+1 Notes on the Free Translation Project
+***************************************
+
+Free software is going international!  The Free Translation Project is a
+way to get maintainers of free software, translators, and users all
+together, so that free software will gradually become able to speak many
+languages.  A few packages already provide translations for their
+messages.
+
+   If you found this 'ABOUT-NLS' file inside a distribution, you may
+assume that the distributed package does use GNU 'gettext' internally,
+itself available at your nearest GNU archive site.  But you do _not_
+need to install GNU 'gettext' prior to configuring, installing or using
+this package with messages translated.
+
+   Installers will find here some useful hints.  These notes also
+explain how users should proceed for getting the programs to use the
+available translations.  They tell how people wanting to contribute and
+work on translations can contact the appropriate team.
+
+1.1 INSTALL Matters
+===================
+
+Some packages are "localizable" when properly installed; the programs
+they contain can be made to speak your own native language.  Most such
+packages use GNU 'gettext'.  Other packages have their own ways to
+internationalization, predating GNU 'gettext'.
+
+   By default, this package will be installed to allow translation of
+messages.  It will automatically detect whether the system already
+provides the GNU 'gettext' functions.  Installers may use special
+options at configuration time for changing the default behaviour.  The
+command:
+
+     ./configure --disable-nls
+
+will _totally_ disable translation of messages.
+
+   When you already have GNU 'gettext' installed on your system and run
+configure without an option for your new package, 'configure' will
+probably detect the previously built and installed 'libintl' library and
+will decide to use it.  If not, you may have to to use the
+'--with-libintl-prefix' option to tell 'configure' where to look for it.
+
+   Internationalized packages usually have many 'po/LL.po' files, where
+LL gives an ISO 639 two-letter code identifying the language.  Unless
+translations have been forbidden at 'configure' time by using the
+'--disable-nls' switch, all available translations are installed
+together with the package.  However, the environment variable 'LINGUAS'
+may be set, prior to configuration, to limit the installed set.
+'LINGUAS' should then contain a space separated list of two-letter
+codes, stating which languages are allowed.
+
+1.2 Using This Package
+======================
+
+As a user, if your language has been installed for this package, you
+only have to set the 'LANG' environment variable to the appropriate
+'LL_CC' combination.  If you happen to have the 'LC_ALL' or some other
+'LC_xxx' environment variables set, you should unset them before setting
+'LANG', otherwise the setting of 'LANG' will not have the desired
+effect.  Here 'LL' is an ISO 639 two-letter language code, and 'CC' is
+an ISO 3166 two-letter country code.  For example, let's suppose that
+you speak German and live in Germany.  At the shell prompt, merely
+execute 'setenv LANG de_DE' (in 'csh'), 'export LANG; LANG=de_DE' (in
+'sh') or 'export LANG=de_DE' (in 'bash').  This can be done from your
+'.login' or '.profile' file, once and for all.
+
+   You might think that the country code specification is redundant.
+But in fact, some languages have dialects in different countries.  For
+example, 'de_AT' is used for Austria, and 'pt_BR' for Brazil.  The
+country code serves to distinguish the dialects.
+
+   The locale naming convention of 'LL_CC', with 'LL' denoting the
+language and 'CC' denoting the country, is the one use on systems based
+on GNU libc.  On other systems, some variations of this scheme are used,
+such as 'LL' or 'LL_CC.ENCODING'.  You can get the list of locales
+supported by your system for your language by running the command
+'locale -a | grep '^LL''.
+
+   Not all programs have translations for all languages.  By default, an
+English message is shown in place of a nonexistent translation.  If you
+understand other languages, you can set up a priority list of languages.
+This is done through a different environment variable, called
+'LANGUAGE'.  GNU 'gettext' gives preference to 'LANGUAGE' over 'LANG'
+for the purpose of message handling, but you still need to have 'LANG'
+set to the primary language; this is required by other parts of the
+system libraries.  For example, some Swedish users who would rather read
+translations in German than English for when Swedish is not available,
+set 'LANGUAGE' to 'sv:de' while leaving 'LANG' to 'sv_SE'.
+
+   Special advice for Norwegian users: The language code for Norwegian
+bokma*l changed from 'no' to 'nb' recently (in 2003).  During the
+transition period, while some message catalogs for this language are
+installed under 'nb' and some older ones under 'no', it's recommended
+for Norwegian users to set 'LANGUAGE' to 'nb:no' so that both newer and
+older translations are used.
+
+   In the 'LANGUAGE' environment variable, but not in the 'LANG'
+environment variable, 'LL_CC' combinations can be abbreviated as 'LL' to
+denote the language's main dialect.  For example, 'de' is equivalent to
+'de_DE' (German as spoken in Germany), and 'pt' to 'pt_PT' (Portuguese
+as spoken in Portugal) in this context.
+
+1.3 Translating Teams
+=====================
+
+For the Free Translation Project to be a success, we need interested
+people who like their own language and write it well, and who are also
+able to synergize with other translators speaking the same language.
+Each translation team has its own mailing list.  The up-to-date list of
+teams can be found at the Free Translation Project's homepage,
+'http://translationproject.org/', in the "Teams" area.
+
+   If you'd like to volunteer to _work_ at translating messages, you
+should become a member of the translating team for your own language.
+The subscribing address is _not_ the same as the list itself, it has
+'-request' appended.  For example, speakers of Swedish can send a
+message to 'sv-request@li.org', having this message body:
+
+     subscribe
+
+   Keep in mind that team members are expected to participate _actively_
+in translations, or at solving translational difficulties, rather than
+merely lurking around.  If your team does not exist yet and you want to
+start one, or if you are unsure about what to do or how to get started,
+please write to 'coordinator@translationproject.org' to reach the
+coordinator for all translator teams.
+
+   The English team is special.  It works at improving and uniformizing
+the terminology in use.  Proven linguistic skills are praised more than
+programming skills, here.
+
+1.4 Available Packages
+======================
+
+Languages are not equally supported in all packages.  The following
+matrix shows the current state of internationalization, as of Jun 2014.
+The matrix shows, in regard of each package, for which languages PO
+files have been submitted to translation coordination, with a
+translation percentage of at least 50%.

+   Some counters in the preceding matrix are higher than the number of
+visible blocks let us expect.  This is because a few extra PO files are
+used for implementing regional variants of languages, or language
+dialects.
+
+   For a PO file in the matrix above to be effective, the package to
+which it applies should also have been internationalized and distributed
+as such by its maintainer.  There might be an observable lag between the
+mere existence a PO file and its wide availability in a distribution.
+
+   If Jun 2014 seems to be old, you may fetch a more recent copy of this
+'ABOUT-NLS' file on most GNU archive sites.  The most up-to-date matrix
+with full percentage details can be found at
+'http://translationproject.org/extra/matrix.html'.
+
+1.5 Using 'gettext' in new packages
+===================================
+
+If you are writing a freely available program and want to
+internationalize it you are welcome to use GNU 'gettext' in your
+package.  Of course you have to respect the GNU Lesser General Public
+License which covers the use of the GNU 'gettext' library.  This means
+in particular that even non-free programs can use 'libintl' as a shared
+library, whereas only free software can use 'libintl' as a static
+library or use modified versions of 'libintl'.
+
+   Once the sources are changed appropriately and the setup can handle
+the use of 'gettext' the only thing missing are the translations.  The
+Free Translation Project is also available for packages which are not
+developed inside the GNU project.  Therefore the information given above
+applies also for every other Free Software Project.  Contact
+'coordinator@translationproject.org' to make the '.pot' files available
+to the translation teams.

+the previous version, bash-5.2-rc4.
+
+1. Changes to Bash
+
+2. Changes to Readline
+
+a. When replacing a history entry, make sure the existing entry has a non-NULL
+   timestamp before copying it; it may have been added by the application, not
+   the history library.
+
+3. New Features in Bash
+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.2-rc4, and
+the previous version, bash-5.2-rc3.
+
+1. Changes to Bash
+
+a. Changed how the compatibility mode enabling of extglob works in conjunction
+   with parsing conditional commands.
+
+b. Fixed a problem with aliases containing command substitutions.
+
+2. Changes to Readline
+

+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.2-rc3, and
+the previous version, bash-5.2-rc2.
+
+1. Changes to Bash
+
+a. Added a compatibility mode feature that causes the parser to parse command
+   substitutions as if extglob were enabled. If it is enabled before execution,
+   parse at execution will succeed. If not, the subsequent execution parse will
+   fail.
+
+b. Fixed an issue with handling a `return' executed in a trap action if the
+   trap is executed while running in a shell function.
+
+2. Changes to Readline
+
+3. New Features in Bash
+
+4. New Features in Readline
+
+a. Readline now checks for changes to locale settings (LC_ALL/LC_CTYPE/LANG)
+   each time it is called, and modifies the appropriate locale-specific display
+   and key binding variables when the locale changes.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.2-rc2, and
+the previous version, bash-5.2-rc1.
+
+1. Changes to Bash
+
+a. Fixed a bug that could disable history saving after a compound array
+   assignment in an interactive shell.
+
+b. Fixed a bug that could cause incorrect error messages when running a DEBUG
+   trap during a conditional or arithmetic command.
+
+c. Fixed a bug that caused test to print an error message when given ! ! arg
+   as arguments.
+
+d. Fixed a bug that resulted in incorrect error messages when completing a
+   backquoted command substitution.
+
+e. Changed command substitution parsing to reproduce the original text more
+   closely when reconsituting the command string from the parsed command.
+
+f. Fixed a bug that could cause an EXIT trap to use the wrong variable context
+   when the errexit option is set.
+
+g. Fixed a bug that could cause the parser to incorrectly delimit a token when
+   an alias expansion ended with a multibyte character.
+
+2. Changes to Readline
+
+3. New Features in Bash
+
+a. Since there is no `declare -' equivalent of `local -', make sure to use
+   `local -' in the output of `local -p'.
+
+b. Null anchored matches in pattern substitution now process `&' in the
+   replacement string, like sed.
+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.2-rc1, and
+the previous version, bash-5.2-beta.
+
+1. Changes to Bash
+
+a. Changes to `wait -p' and how it sets the variable name in the presence of
+   valid and invalid PID arguments.
+
+b. Fixed a bug that caused compgen to dump core if the completion engine was
+   not initialized.
+
+c. Fixed a memory leak in the variable name programmable completion code.
+
+d. Here-documents and here-strings use tempfiles if the shell compatibility
+   level is 50 or lower.
+
+e. Non-interactive shells exit on a syntax error encountered while parsing a
+   command substitution.
+
+f. Fixed a bug with inherited parser state while parsing a command substitution.
+
+g. Fixed a bug that caused the shell not to check for terminating signals
+   after executing the command_string supplied with `-c' and before executing
+   the exit trap.
+
+h. Changes to avoid a make race condition while generating builtins.c.
+
+i. Make it explicit that BASH_REMATCH is always a global variable, and that
+   local copies are (currently) ignored.
+
+j. Fixed a bug that caused an ambiguous redirection (>&word) to be printed
+   incorrectly (>&word) if no file descriptor was supplied.
+
+2. Changes to Readline
+
+a. Fixed a bug that caused rl_eof_found to be set prematurely while reading a
+   multi-character key sequence in callback mode.
+
+3. New Features in Bash
+
+a. In posix mode, the `printf' builtin checks for the `L' length modifier and
+   uses long double for floating point conversion specifiers if it's present,
+   double otherwise.
+
+b. The `globbing' completion code now takes the `globstar' option into account.
+
+c. `suspend -f' now forces the shell to suspend even if job control is not
+   currently enabled.
+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.2-beta, and
+the previous version, bash-5.2-alpha.
+
+1. Changes to Bash
+
+a. Fixed a problem with command-oriented history and multi-line commands that
+   caused embedded blank lines to be run together.
+
+b. Changed the way `&' is quoted when performing pattern substitution and
+   `patsub_replacement' is enabled.
+
+c. Fixed some integer overflows when expanding strings or reading the output
+   of command substitution larger than 2GB.
+
+d. `wait -p' without the `-n' option now does something useful if there are no
+   jobs.
+
+e. Fixed an issue with read timeouts in posix mode.
+
+f. Changed here-document processing to process $'...' and $"..." only when they
+   appear in the WORD portion of ${PARAM OP WORD} in the here-document body
+   and the body is being expanded.
+
+g. Changed alias expansion in command substitution to be posix-conformant
+   (performed while initially parsing the command substitution) when in posix
+   mode.
+
+h. Bash optimizes away more forks in subshells.
+
+i. Here-document construction now performs quote removal on the here-document
+   delimiter only if it's marked as quoted, which prevents quote characters in
+   command substitutions from being removed.
+
+j. Prompt string expansion now gives invisible characters in the expansion of
+   the \w, \W, and \s escape sequences a visible representation to avoid
+   problems with redisplay.
+
+k. Fixed a problem with SIGINT during the execution of a command bound with
+   `bind -x' affecting the saved terminal settings.
+
+l. Fixed an inconsistency with how $@ expands in a construct like ${@:+set}
+   or ${array[@]:+set} in the presence of null positional parameters or
+   array elements.
+
+2. Changes to Readline
+
+a. Prevent some display problems when running a command as the result of a
+   trap or one bound using `bind -x' and the command generates output.
+
+b. Fixed an issue with multi-line prompt strings that have one or more
+   invisible characters at the end of a physical line.
+
+c. Fixed an issue that caused a history line's undo list to be cleared when
+   it should not have been.
+
+3. New Features in Bash
+
+a. There is a new bindable readline command name: `vi-edit-and-execute-command'.
+
+4. New Features in Readline
+
+a. Two new bindable string variables: active-region-start-color and
+   active-region-end-color. The first sets the color used to display the
+   active region; the second turns it off. If set, these are used in place
+   of terminal standout mode.
+
+b. New readline state (RL_STATE_EOF) and application-visible variable
+   (rl_eof_found) to allow applications to detect when readline reads EOF
+   before calling the deprep-terminal hook.
+
+c. There is a new configuration option: --with-shared-termcap-library, which
+   forces linking the shared readline library with the shared termcap (or
+   curses/ncurses/termlib) library so applications don't have to do it.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.2-alpha, and
+the previous version, bash-5.1-release.
+
+1. Changes to Bash
+
+a. Fixed a bug that assigned a value to the variable name supplied as an
+   argument to `wait -p' when there were no jobs.
+
+b. Fixed a bug that resulted in performing incorrect word expansion on the
+   key/value pairs in a compound array assignment.
+
+c. Fixed a bug that could put the child forked to run a command substitution
+   into the wrong process group.
+
+d. Fixed a problem that could cause the lastpipe option to work incorrectly if
+   file descriptor 0 was closed.
+
+e. Bash tries to suppress traps if a forked child receives a trapped signal
+   before it has a chance to reset its signal handlers.
+
+f. Fixed several memory leaks in compound array assignments.
+
+g. Fixed a problem with performing an assignment with `+=' to an array element
+   that was the value of a nameref.
+
+h. Fixed a bug that could cause a nameref containing an array reference using
+   `@' or `*' not to expand to multiple words.
+
+i. Fixed a bug where extended glob functions could match `.' or `..' when it
+   wasn't explicitly specified, even if dotglob was set.
+
+j. Fixed a bug that caused non-interactive posix-mode shells not to exit on a
+   variable assignment error while assigning into the temporary environment.
+
+k. Fixed a bug that caused parsing errors if an alias contained a compound
+   array assignment.
+
+l. Fixed a couple of instances where bash checked syntax too aggressively when
+   trying to determine how to add a partial command to command-oriented
+   history.
+
+m. Fixed a parser problem that caused it not to allow reserved words to follow
+   the `((' and `[[' commands.
+
+n. Fixed a bad offset calculation when using negative offsets to `history -d'.
+
+o. Fixed an off-by-one error that caused a read past the end of a buffer when
+   reading a multibyte character from the output of a command substitution.
+
+p. Fixed a problem with a failed `exec' command not setting $? to the right
+   value for an exit trap.
+
+q. Fixed a problem that caused bash not to unlink FIFOs created as part of
+   expanding redirections for an external command.
+
+r. Fixed a bug that could cause aliases not to be expanded in case statements.
+
+s. Fixed a bug that could cause word completion to attempt programmable
+   completion for the target of a redirection, instead of filename completion.
+
+t. Fixed a bug that could result in errors after rebinding a key sequence with
+   `bind -x' multiple times.
+
+u. Fixed a problem that could result in not quoting the result when performing
+   command name completion with a glob pattern in the command name.
+
+v. `mapfile' now uses fully-buffered reads in more cases, which should improve
+   bulk read performance.
+
+w. Fixed a bug that caused `wait -n' to not reset its internal state when
+   interrupted by a signal, resulting in subsequent calls failing.
+
+x. Fixed a bug with parsing numeric arguments to readline key sequences
+   installed with `bind -x'.
+
+y. Bash suppresses forking in several additional cases, including most uses
+   of $(<file).
+
+z. If there are multiple `!' tokens in a [[ command, toggle the invert state
+   instead of setting it unconditionally.
+
+aa. Fixed a bug where running `fc' on an empty history list would cause the
+    shell to crash.
+
+bb. Word completion now checks whether or not a quote character closes a
+    quoted string begun on a previous line, so readline doesn't interpret the
+    quote as starting a new quoted string.
+
+cc. Fixed a typo that translated \UNNNNNNNN characters that were not valid in
+    the current locale encoding as \uNNNNNNNN.
+
+dd. Fixed an issue that could cause bash to print timing statistics for the
+    wrong command when `set -e' causes a command to fail.
+
+ee. Bash now runs the exit trap in function context if a failed command in
+    the function causes the shell to exit.
+
+ff. Some fixes to how subshells modify $SHLVL.
+
+gg. Fixed a bug that caused `mapfile -t' not to remove the delimiter when the
+    delimiter is > 128 in the current encoding.
+
+hh. Fixed a problem that could cause the shell to attempt to free unallocated
+    memory if an expansion error occurred.
+
+ii. Fixed a bug in the bash malloc implementation of malloc_usable_size. Bash
+    did not use it, but it could cause problems with library functions that
+    did.
+
+jj. If the `exec' builtin fails, and the shell does not exit, it restores
+    trapped signals to their trapped state.
+
+kk. Fixed a bug that could cause variable assignment arguments to `declare' to
+    expand variables using attributes that the call to declare was turning off.
+
+ll. Fixed a bug with LINENO and arithmetic for commands.
+
+mm. Fixed a posix-mode bug that caused tildes not to be expanded after an
+    unquoted colon on the right side of an assignment statement.
+
+nn. Fixed a problem with `caller' and line numbers when executing an ERR trap.
+
+oo. Fixed a problem that could make the value returned by ${a:=b} not be the
+    final value assigned to a (e.g., if `a' has an attribute that modifies
+    the value on assignment).
+
+pp. Fixed a problem with saving multi-line here-documents to the history list
+    where the here-document delimiter does not appear on the first line.
+
+qq. Fixed a bug with using += to assign to dynamic variables like RANDOM.
+
+rr. Fixed a bug that caused `set -n' to modify $? if set after execution had
+    started.
+
+ss. Builtins like printf/read/wait now behave more consistently when assigning
+    arbitrary keys to associative arrays (like `]'. when appropriately quoted).
+
+tt. Fixed a problem with here-document collection printing the wrong prompt
+    when parsing a compound list in an interactive shell.
+
+uu. Fixed a problem with quoting shell expansion characters (like `$') when
+    they appear in a tab-completed word along with characters that do need
+    quoting (e.g.. $HOME/VirtualBox VMs).
+
+2. Changes to Readline
+
+a. Fixed a problem with cleaning up active marks when using callback mode.
+
+b. Fixed a problem with arithmetic comparison operators checking the version.
+
+c. Fixed a problem that could cause readline not to build on systems without
+   POSIX signal functions.
+
+d. Fixed a bug that could cause readline to crash if the application removed
+   the callback line handler before readline read all typeahead.
+
+e. Added additional checks for read errors in the middle of readline commands.
+
+f. Fixed a redisplay problem that occurred when switching from the digit-
+   argument prompt `(arg: N)' back to the regular prompt and the regular
+   prompt contained invisible characters.
+
+g. Fixed a problem with restoring the prompt when aborting an incremental
+   search.
+
+h. Fix a problem with characters > 128 not being displayed correctly in certain
+   single-byte encodings.
+
+i. Fixed a problem with unix-filename-rubout that caused it to delete too much
+   when applied to a pathname consisting only of one or more slashes.
+
+j. Fixed a display problem that caused the prompt to be wrapped incorrectly if
+   the screen changed dimensions during a call to readline() and the prompt
+   became longer than the screen width.
+
+k. Fixed a problem that caused the \r output by turning off bracketed paste
+   to overwrite the line if terminal echo was disabled.
+
+l. Fixed a bug that could cause colored-completion-prefix to not display if
+   completion-prefix-display-length was set.
+
+m. Fixed a problem with line wrapping prompts when a group of invisible
+   characters runs to the right edge of the screen and the prompt extends
+   longer then the screen width.
+
+n. Fixed a couple problems that could cause rl_end to be set incorrectly by
+   transpose-words.
+
+3. New Features in Bash
+
+a. The bash malloc returns memory that is aligned on 16-byte boundaries.
+
+b. There is a new internal timer framework used for read builtin timeouts.
+
+c. Rewrote the command substitution parsing code to call the parser recursively
+   and rebuild the command string from the parsed command. This allows better
+   syntax checking and catches errors much earlier. Along with this, if
+   command substitution parsing completes with here-documents remaining to be
+   read, the shell prints a warning message and reads the here-document bodies
+   from the current input stream.
+
+d. The `ulimit' builtin now treats an operand remaining after all of the options
+   and arguments are parsed as an argument to the last command specified by
+   an option. This is for POSIX compatibility.
+
+e. Here-document parsing now handles $'...' and $"..." quoting when reading the
+   here-document body.
+
+f. The `shell-expand-line' and `history-and-alias-expand-line' bindable readline
+   commands now understand $'...' and $"..." quoting.
+
+g. There is a new `spell-correct-word' bindable readline command to perform
+   spelling correction on the current word.
+
+h. The `unset' builtin now attempts to treat arguments as array subscripts
+   without parsing or expanding the subscript, even when `assoc_expand_once'
+   is not set.
+
+i. There is a default value for $BASH_LOADABLES_PATH in config-top.h.
+
+j. Associative array assignment and certain instances of referencing (e.g.,
+   `test -v') now allow `@' and `*' to be used as keys.
+
+k. Bash attempts to expand indexed and associative array subscripts only
+   once when executing shell constructs and word expansions.
+
+l. The `unset' builtin allows a subscript of `@' or `*' to unset a key with
+   that value for associative arrays instead of unsetting the entire array
+   (which you can still do with `unset arrayname'). For indexed arrays, it
+   removes all elements of the array without unsetting it (like `A=()').
+
+m. Additional builtins (printf/test/read/wait) do a better job of not
+   parsing array subscripts if array_expand_once is set.
+
+n. New READLINE_ARGUMENT variable set to numeric argument for readline commands
+   defined using `bind -x'.
+
+o. The new `varredir_close' shell option causes bash to automatically close
+   file descriptors opened with {var}<fn and other styles of varassign
+   redirection unless they're arguments to the `exec' builtin.
+
+p. The `$0' special parameter is now set to the name of the script when running
+   any (non-interactive) startup files such as $BASH_ENV.
+
+q. The `enable' builtin tries to load a loadable builtin using the default
+   search path if `enable name' (without any options) attempts to enable a
+   non-existent builtin.
+
+r. The `printf' builtin has a new format specifier: %Q. This acts like %q but
+   applies any specified precision to the original unquoted argument, then
+   quotes and outputs the result.
+
+s. The new `noexpand_translations' option controls whether or not the translated
+   output of $"..." is single-quoted.
+
+t. There is a new parameter transformation operator: @k. This is like @K, but
+   expands the result to separate words after word splitting.
+
+u. There is an alternate array implementation, selectable at `configure' time,
+   that optimizes access speed over memory use (use the new configure
+    --enable-alt-array-implementation option).
+
+v. If an [N]<&WORD- or [N]>&WORD- redirection has WORD expand to the empty
+   string, treat the redirection as [N]<&- or [N]>&- and close file descriptor
+   N (default 0).
+
+w. Invalid parameter transformation operators are now invalid word expansions,
+   and so cause fatal errors in non-interactive shells.
+
+x. New shell option: patsub_replacement. When enabled, a `&' in the replacement
+   string of the pattern substitution expansion is replaced by the portion of
+   the string that matched the pattern. Backslash will escape the `&' and
+   insert a literal `&'.
+
+y. `command -p' no longer looks in the hash table for the specified command.
+
+z. The new `--enable-translatable-strings' option to `configure' allows $"..."
+   support to be compiled in or out.
+
+aa. The new `globskipdots' shell option forces pathname expansion never to
+    return `.' or `..' unless explicitly matched. It is enabled by default.
+
+bb. Array references using `@' and `*' that are the value of nameref variables
+    (declare -n ref='v[@]' ; echo $ref) no longer cause the shell to exit if
+    set -u is enabled and the array (v) is unset.
+
+4. New Features in Readline
+
+a. There is now an HS_HISTORY_VERSION containing the version number of the
+   history library for applications to use.
+
+b. History expansion better understands multiple history expansions that may
+   contain strings that would ordinarily inhibit history expansion (e.g.,
+   `abc!$!$').
+
+c. There is a new framework for readline timeouts, including new public
+   functions to set timeouts and query how much time is remaining before a
+   timeout hits, and a hook function that can trigger when readline times
+   out. There is a new state value to indicate a timeout.
+
+d. Automatically bind termcap key sequences for page-up and page-down to
+   history-search-backward and history-search-forward, respectively.
+
+e. There is a new `fetch-history' bindable command that retrieves the history
+   entry corresponding to its numeric argument. Negative arguments count back
+   from the end of the history.
+
+f. `vi-undo' is now a bindable command.
+
+g. There is a new option: `enable-active-region'. This separates control of
+   the active region and bracketed-paste. It has the same default value as
+   bracketed-paste, and enabling bracketed paste enables the active region.
+   Users can now turn off the active region while leaving bracketed paste
+   enabled.
+
+h. rl_completer_word_break_characters is now `const char *' like
+   rl_basic_word_break_characters.
+
+i. Readline looks in $LS_COLORS for a custom filename extension
+   (*.readline-colored-completion-prefix) and uses that as the default color
+   for the common prefix displayed when `colored-completion-prefix' is set.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.1-rc3, and
+the previous version, bash-5.1-rc2.
+
+1. Changes to Bash
+
+a. The `assoc_expand_once' option now affects the evaluation of the -v primary
+   to test and the [[ compound command.
+
+2. Changes to Readline
+
+a. Fixed a bug that could cause point to be set beyond the end of the line
+   buffer when aborting an incremental search.
+
+3. New Features in Bash
+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.1-rc2, and
+the previous version, bash-5.1-rc1.
+
+1. Changes to Bash
+
+a. Process substitutions started from an interactive shell no longer have their
+   standard input implicitly redirected from /dev/null.
+
+b. Fixed an issue with setting the SIGINT trap handler in an interactive shell
+   when temporarily running $PROMPT_COMMAND non-interactively.
+
+2. Changes to Readline
+
+a. Terminals that are named "dumb" or unknown do not enable bracketed paste
+   by default.
+
+b. Ensure that disabling bracketed paste turns off highlighting the incremental
+   search string when the search is successful.

+   double quotes.
+
+c. Fixed a case where the shells's exit status could be greater than 255.
+
+d. Modified changed to process substitution so the executed command has its
+   stdin redirected from /dev/null if it was previously interactive and
+   reading commands from the terminal.
+
+2. New Features in Bash
+
+a. There is a new contributed loadable builtin: asort.
+

+   initialized.
+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.1-beta, and
+the previous version, bash-5.1-alpha.
+
+1. Changes to Bash
+

+
+d. A few minor changes to move potential uses of stdio functions out of signal
+   handling paths.
+
+e. Make sure SIGCHLD is blocked in all cases where waitchld() is not called
+   from a signal handler.
+
+f. Changed `command' builtin processing so it no longer starts an extra process
+   when run asynchronously (command x &).
+
+g. Avoid performing tilde expansion after `:' in words that look like assignment
+   statements when in posix mode.
+
+h. Slight changes to how the `complete' builtin prints out options and actions
+   for completion specifications.
+
+i. Several changes to how `local -' restores the values of options and
+   $SHELLOPTS.
+
+j. Don't treat a word in a compound assignment as an assignment statement
+   unless it has a valid subscript before the `='.
+
+k. Fixed a bug with the DEBUG trap and process substitution that caused the
+   terminal's process group to be set incorrectly.
+
+l. Fixed a bug that left readline's signal handlers installed while running a
+   shell command from a bindable readline command.
+
+m. Fixed the `fc' builtin to clamp out of range history specifications at the
+   boundaries of the history list for POSIX conformance.
+
+n. Fixed a bug that caused ${foo@a} to treat foo as an unset variable if it
+   was an array without a value for subscript 0/"0" but had other set
+   elements.
+
+o. Fixed a bug that caused the history code to attempt to parse command
+   substitutions looking for shell comments before adding them to the history,
+   even while parsing here-documents.
+
+p. Fixed a bug that could cause a syntax error in a command read by `eval' to
+   exit an interactive shell.
+
+2. New Features in Bash

+
+c. Bash attempts to optimize away forks in the last command in a function body
+   under appropriate circumstances.
+
+d. The globbing code now uses fnmatch(3) to check collation elements (if
+   available) even in cases without multibyte characters.
+
+e. The `fg' and `bg' builtins now return an error in a command substitution
+   when asked to restart a job inherited from the parent shell.
+
+f. The shell now attempts to unlink all FIFOs on exit, whether a consuming

+
+3. Changes to Readline
+
+a. Make sure that all undo groups are closed when leaving vi insertion mode.
+
+b. Make sure that the vi-mode `C' and `c' commands enter insert mode even if
+   the motion command doesn't have any effect.
+
+c. Fixed several potential memory leaks in the callback mode context handling.
+
+d. If readline is handling a SIGTTOU, make sure SIGTTOU is blocked while
+   executing the terminal cleanup code, since it's no longer run in a signal
+   handling context.
+
+4. New Features in Readline
+
+a. The signal cleanup code now blocks SIGINT while processing after a SIGINT.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.1-alpha, and
+the previous version, bash-5.0-release.
+
+1. Changes to Bash
+
+a. Fixed a bug that caused a posix-mode shell to not exit if the return builtin
+   was executed outside a function or dot script.
+
+b. Fixed a bug where `declare +f' could potentially turn off the function
+   attribute.
+
+c. Restored bash-4.4 pathname expansion behavior when a word to be expanded had
+   only backslashes, not any of the other globbing characters. This came after
+   an extensive POSIX group discussion (interp #1234).
+
+d. There are more changes to avoid performing word expansions multiple times on
+   arithmetic expressions.
+
+e. Fixed a bug with alias expansion when the alias ends with a TAB.
+
+f. Fixed a bug that caused programmable completion to return an error if the
+   shell function name supplied as an argument to `complete -F' was invalid.
+
+g. There are several fixes to buffer overflows found as the result of fuzzing
+   with random input.
+
+h. Fixed a bug that caused the edit-and-execute-command editing command to
+   start with the previous history line if invoked on an empty line.
+
+i. Fixed a bug that potentially caused `bind --help' to change readline's
+   output stream.
+
+j. Turning off posix mode now restores the vi-insertion mode binding for TAB
+   that was in effect when posix mode was enabled.
+
+k. Restore the previous state of job control being enabled if `exec' fails in
+   an interactive shell.
+
+l. Fixed a bug that caused the terminal's process group to be set incorrectly
+   if job control was turned off before starting an interactive shell.
+
+m. Fixed a bug that caused a crash when HISTSIZE=0.
+
+n. Fixed a word expansion bug that caused null strings on the rhs of expansions
+   to be discarded incorrectly.
+
+o. History list management does a better job of handling the situation where
+   the number of history entries from the current shell session is greater than
+   the number of entries in the history list.
+
+p. Fixed a bug that caused the `fc' builtin to attempt to dereference a newly-
+   freed history entry.
+
+q. Fixed a bug that made the `Q' variable transformation not work well with
+   `set -u'.
+
+r. There are several word expansion fixes for expanding $* and $@ in contexts
+   where word splitting is not going to be performed, since each positional
+   parameter must expand to a separate word.
+
+s. Fixed a bug that could cause ^D to exit bash immediately even if there were
+   stopped jobs.
+
+t. Fixed a bug with double-quoting and backslash-quoting strings containing
+   multibyte characters for reuse.
+
+u. Fixed a bug that caused the line number to be reported incorrectly if the
+   shell executed a (command) subshell.
+
+v. Fixed a bug that caused the shell to fail to reap process substitutions
+   when they went out of scope, which had unpredictable results.
+
+w. Fixed a bug that caused null strings in arguments to [[ conditional command
+   operators to compare incorrectly.
+
+x. Changed the behavior of `wait' without arguments to only wait for background
+   processes the current shell instance started, not background children it may
+   have inherited.
+
+y. Fixed a bug that could cause command substitution to leave file descriptors
+   open if the shell received many SIGINTs.
+
+z. Bash now behaves better if the `**' filename expansion operator encounters a
+   symbolic link to a directory, avoiding more cases where it might return
+   duplicate pathnames.
+
+aa. Programmable completion now canonicalizes directory names in the same way
+    as bash word completion, so `..' is handled consistently.
+
+bb. Fixed a bug when using RETURN as the delimiter to the read builtin; it
+    caused readline to set the binding for RETURN incorrectly.
+
+cc. Fixed a bug that caused `history -d' to delay printing an out-of-range
+    error message.
+
+dd. Fixed a bug with `bash -c command' where `command' ends with an expanded
+    alias.
+
+ee. Fixed a bug that could result in `history -n' adding spurious line feeds to
+    commands in the history list.
+
+ff. The $RANDOM random number generator now XORs the top and bottom halves of
+    the internal 32-bit value to introduce more randomness. Setting the shell
+    compatibility level to 50 or lower undoes this.
+
+gg. Fixed several problems caused by running the DEBUG trap on simple commands
+    executed as part of a pipeline.
+
+ii. Fixed a bug that didn't allow `bind -r' to remove the binding for \C-@.
+
+jj. Several fixes to the bash-backward-shellword bindable readline command to
+    behave better when at the last character on the line.
+
+kk. If `set -x' is enabled, bash doesn't print a command twice if it's run by
+    the `command' builtin.
+
+ll. Fixed a bug with printing function definitions containing here documents.
+
+mm. Fixed a bug that could cause the `bind' builtin to set $? to -1.
+
+nn. Fixed a bug that didn't reset the timezone information correctly when the
+    TZ variable was unset.
+
+oo. Fixed several issues with assigning an associative array variable using a
+    compound assignment that expands the value of the same variable.
+
+pp. Fixed several places where the shell set $? without setting PIPESTATUS.
+
+qq. Fixed a problem with glob bracket expressions containing invalid character
+    classes, collating symbols, or equivalence classes -- they should not
+    require a closing right bracket.
+
+rr. Fixed a bug where running a builtin in a subshell did not run the EXIT trap.
+
+ss. Fixed several problems with posix-mode variable assignments preceding
+    shell function calls and posix special builtins, so that they create and
+    modify variables at the current scope.
+
+tt. Fix history initialization so `bash +o history' works as expected.
+
+uu. Fixed a bug in the bindable edit-and-execute-command command that could
+    interfere with the shell's parsing state.
+
+vv. Fixed an issue with nested traps running command substitutions in command
+    lines with command substitutions.
+
+ww. Fixed a bug with globbing pathnames that contain invalid multibyte
+    characters (sequences that don't correspond to a character in the current
+    locale).
+
+xx. Fixed a bug that caused the shell not to exit if a function definition
+    failed while errexit was enabled.
+
+yy. Process substitution processes now get their input from /dev/null, since
+    they are asynchronous, not interactive, and not jobs.
+
+zz. Setting nocaseglob no longer turns on case-insensitive regexp matching.
+
+aaa. Fixed a bug that resulted in extra blank lines being added to some history
+     entries containing here-documents.
+
+bbb. Fixed a bug that resulted in incorrect matching of some patterns in word
+     expansion if they expanded to the empty string.
+
+ccc. Fixed here-string expansion so it behaves the same as expansion of the
+     rhs of an assignment statement.
+
+ddd. Changed here-document parsing to no longer allow the end of the here
+     document to delimit a command substitution.
+
+eee. Several fixes to history expansion: multiple :p modifiers work, a ^ word
+     designator works as part of a range, and a `-' is treated as part of a
+     search string if it immediately follows a `!'.
+
+fff. Fixed a bug in pattern substitution with null matches in a string
+     containing multibyte characters.
+
+ggg. Unbinding a key sequence bound with `bind -x' now removes the key sequence
+     from the additional keymap `bind -x' uses.
+
+hhh. Fixed a bug with command start detection for completion so that it doesn't
+     mistake brace expansion for the start of a command.
+
+iii. Fixed a bug that caused local variables with the same name as variables
+     appearing in a function's temporary environment to not be marked as local.
+
+jjj. Fixed a bug that could cause SIGCHLD to be blocked when executing return
+     or exec in the rightmost pipeline element with lastpipe enabled.
+
+kkk. Fixed a bug that could result in commands without the execute bit set
+     being added to the command hash table.
+
+lll. Fixed a bug that allowed non-digits to follow the `#' in a `base#number'
+     integer constant.
+
+mmm. Fixed a bug that made `time -- command' attempt to execute `--'.
+
+nnn. Fixed a couple of bugs with variable transformation using arrays
+     subscripted with `*' or `@'.
+
+ooo. A failure to create a variable using `declare' in a function no longer
+     causes the function to return immediately.
+
+ppp. Fixed a bug that could cause the := word expansion to add a non-null
+     value if attempting to assign a null string when double-quoted.
+
+qqq. Fixed a bug that could cause backslashes quoting double quotes in here
+     document bodies to not be removed when expanding the body.
+
+rrr. Fixed a bug that caused commands following a subshell while the shell is
+     reading input from stdin but not interactive, while job control is
+     enabled, to be executed twice.
+
+sss. Fixed a bug where receiving SIGTERM from a different process while
+     readline was active could cause the shell to terminate.
+
+ttt. In posix mode, running a trap after the read builtin now sees the exit
+     status of the read builtin (e.g., 130 after a SIGINT) in $?.
+
+uuu. Fixed a bug with nameref variables referencing array subscripts used in
+     arithmetic expressions.
+
+vvv. Fixed a bug that caused the pipeline process group id to be reset in the
+     middle of a command list run by a shell started to run a command
+     substitution.
+
+www. Restricted shells can no longer read and write history files with pathnames
+     containing slashes.
+
+xxx. Fixed a couple of problems with 0 and -0 used as arguments to `fc' when
+     not listing commands from the history.
+
+yyy. When `test' is supplied four or more arguments, treat an argument that
+     looks like an operator (e.g., -e), but is in a place where only a string
+     is valid, as a string, as it would be when using the POSIX rules, instead
+     of an operator with a missing argument.
+
+zzz. There is no `compat50' shopt option. Changes to the shell compatibility
+     level should use the BASH_COMPAT variable.
+
+aaaa. Redirection failures with compound commands are now treated as errors
+      that cause the shell to exit if `errexit' is enabled.
+
+bbbb. Redirection failure error messages no longer expand the word in the
+      redirection again.
+
+cccc. History expansion is no longer performed while parsing a here-document
+      inside a command substitution.
+
+2. Changes to Readline
+
+a. There are a number of fixes that were found as the result of fuzzing with
+   random input.
+
+b. Changed the revert-all-at-newline behavior to make sure to start at the end
+   of the history list when doing it, instead of the line where the user hit
+   return.
+
+c. When parsing `set' commands from the inputrc file or an application, readline
+   now allows trailing whitespace.
+
+d. Fixed a bug that left a file descriptor open to the history file if the
+   file size was 0.
+
+e. Fixed a problem with binding key sequences containing meta characters.
+
+f. Fixed a bug that caused the wrong line to be displayed if the user tried to
+   move back beyond the beginning of the history list, or forward past the end
+   of the history list.
+
+g. If readline catches SIGTSTP, it now sets a hook that allows the calling
+   application to handle it if it desires.
+
+h. Fixed a redisplay problem with a prompt string containing embedded newlines.
+
+i. Fixed a problem with completing filenames containing invalid multibyte
+   sequences when case-insensitive comparisons are enabled.
+
+j. Fixed a redisplay problem with prompt strings containing invisible multibyte
+   characters.
+
+k. Fixed a problem with multibyte characters mapped to editing commands that
+   modify the search string in incremental search.
+
+l. Fixed a bug with maintaining the key sequence while resolving a bound
+   command in the presence of ambiguous sequences (sequences with a common
+   prefix), in most cases while attempting to unbind it.
+
+m. Fixed several buffer overflows found as the result of fuzzing.
+
+n. Reworked backslash handling when translating key sequences for key binding
+   to be more uniform and consistent, which introduces a slight backwards
+   incompatibility.
+
+o. Fixed a bug with saving the history that resulted in errors not being
+   propagated to the calling application when the history file is not writable.
+
+p. Readline only calls chown(2) on a newly-written history file if it really
+   needs to, instead of having it be a no-op.
+
+q. Readline now behaves better when operate-and-get-next is used when the
+   history list is `full': when there are already $HISTSIZE entries.
+
+r. Fixed a bug that could cause vi redo (`.') of a replace command not to work
+   correctly in the C or POSIX locale.
+
+s. Fixed a bug with vi-mode digit arguments that caused the last command to be
+   set incorrectly. This prevents yank-last-arg from working as intended, for
+   example.
+
+3. New Features in Bash
+
+a. `bind -x' now supports different bindings for different editing modes and
+   keymaps.
+
+b. Bash attempts to optimize the number of times it forks when executing
+   commands in subshells and from `bash -c'.
+
+c. Here documents and here strings now use pipes for the expanded document if
+   it's smaller than the pipe buffer size, reverting to temporary files if it's
+   larger.
+
+d. There are new loadable builtins: mktemp, accept, mkfifo, csv, cut/lcut
+
+e. In posix mode, `trap -p' now displays signals whose disposition is SIG_DFL
+   and those that were SIG_IGN when the shell starts.
+
+f. The shell now expands the history number (e.g., in PS1) even if it is not
+   currently saving commands to the history list.
+
+g. `read -e' may now be used with arbitrary file descriptors (`read -u N').
+
+h. The `select' builtin now runs traps if its internal call to the read builtin
+   is interrupted by a signal.
+
+i. SRANDOM: a new variable that expands to a 32-bit random number that is not
+   produced by an LCRNG, and uses getrandom/getentropy, falling back to
+   /dev/urandom or arc4random if available. There is a fallback generator if
+   none of these are available.
+
+j. shell-transpose-words: a new bindable readline command that uses the same
+   definition of word as shell-forward-word, etc.
+
+k. The shell now adds default bindings for shell-forward-word,
+   shell-backward-word, shell-transpose-words, and shell-kill-word.
+
+l. Bash now allows ARGV0 appearing in the initial shell environment to set $0.
+
+m. If `unset' is executed without option arguments, bash tries to unset a shell
+   function if a name argument cannot be a shell variable name because it's not
+   an identifier.
+
+n. The `test -N' operator uses nanosecond timestamp granularity if it's
+   available.
+
+o. Bash posix mode now treats assignment statements preceding shell function
+   definitions the same as in its default mode, since POSIX has changed and
+   no longer requires those assignments to persist after the function returns
+   (POSIX interp 654).
+
+p. BASH_REMATCH is no longer readonly.
+
+q. wait: has a new -p VARNAME option, which stores the PID returned by `wait -n'
+   or `wait' without arguments.
+
+r. Sorting the results of pathname expansion now uses byte-by-byte comparisons
+   if two strings collate equally to impose a total order; the result of a
+   POSIX interpretation (#963 and #1070).
+
+s. Bash now allows SIGINT trap handlers to execute recursively.
+
+t. Bash now saves and restores state around setting and unsetting posix mode,
+   instead of having unsetting posix mode set a known state.
+
+u. Process substitution is now available in posix mode.
+
+v. READLINE_MARK: a new variable available while executing commands bound with
+   `bind -x', contains the value of the mark.
+
+w. Bash removes SIGCHLD from the set of blocked signals if it's blocked at shell
+   startup.
+
+x. `test -v N' can now test whether or not positional parameter N is set.
+
+y. `local' now honors the `-p' option to display all local variables at the
+    current context.
+
+z. The `@a' variable transformation now prints attributes for unset array
+   variables.
+
+aa. The `@A' variable transformation now prints a declare command that sets a
+    variable's attributes if the variable has attributes but is unset.
+
+bb. `declare' and `local' now have a -I option that inherits attributes and
+    value from a variable with the same name at a previous scope.
+
+cc. When run from a -c command, `jobs' now reports the status of completed jobs.
+
+dd. New `U', `u', and `L' parameter transformations to convert to uppercase,
+    convert first character to uppercase, and convert to lowercase,
+    respectively.
+
+ee. PROMPT_COMMAND: can now be an  array variable, each element of which can
+    contain a command to be executed like a string PROMPT_COMMAND variable.
+
+ff. `ulimit' has a -R option to report and set the RLIMIT_RTTIME resource.
+
+gg. Associative arrays may be assigned using a list of key-value pairs within
+    a compound assignment. Compound assignments where the words are not of
+    the form [key]=value are assumed to be key-value assignments. A missing or
+    empty key is an error; a missing value is treated as NULL. Assignments may
+    not mix the two forms.
+
+hh. New `K' parameter transformation to display associative arrays as key-
+    value pairs.
+
+ii. Writing history to syslog now handles messages longer than the syslog max
+    length by writing multiple messages with a sequence number.
+
+jj. SECONDS and RANDOM may now be assigned using arithmetic expressions, since
+    they are nominally integer variables. LINENO is not an integer variable.
+
+kk. Bash temporarily suppresses the verbose option when running the DEBUG trap
+    while running a command from the `fc' builtin.
+
+ll. `wait -n' now accepts a list of job specifications as arguments and will
+    wait for the first one in the list to change state.
+
+mm. The associative array implementation can now dynamically increase the
+    size of the hash table based on insertion patterns.
+
+nn. HISTFILE is now readonly in a restricted shell.
+
+oo. The bash malloc now returns memory that is 16-byte aligned on 64-bit
+    systems.
+
+4. New Features in Readline
+
+a. If a second consecutive completion attempt produces matches where the first
+   did not, treat it as a new completion attempt and insert a match as
+   appropriate.
+
+b. Bracketed paste mode works in more places: incremental search strings, vi
+   overstrike mode, character search, and reading numeric arguments.
+
+c. Readline automatically switches to horizontal scrolling if the terminal has
+   only one line.
+
+d. Unbinding all key sequences bound to a particular readline function now
+   descends into keymaps for multi-key sequences.
+
+e. rl-clear-display: new bindable command that clears the screen and, if
+   possible, the scrollback buffer (bound to emacs mode M-C-l by default).
+
+f. New active mark and face feature: when enabled, it will highlight the text
+   inserted by a bracketed paste (the `active region') and the text found by
+   incremental and non-incremental history searches. This is tied to bracketed
+   paste and can be disabled by turning off bracketed paste.
+
+g. Readline sets the mark in several additional commands.
+
+h. Bracketed paste mode is enabled by default.
+
+i. Readline tries to take advantage of the more regular structure of UTF-8
+   characters to identify the beginning and end of characters when moving
+   through the line buffer.
+
+j. The bindable operate-and-get-next command (and its default bindings) are
+   now part of readline instead of a bash-specific addition.

+   to an associative array with assoc_expand_once enabled.
+
+e. Fixed a bug that could cause a huge memory allocation when completing a
+   word beginning with an invalid tilde expansion.

+
+h. Fixed a bug that caused the output of `set' to cut off some variables before
+   printing the value.
+
+i. Treat a failure to assign a variable when using the ${x:=value} expansion
+   as an expansion error, so non-interactive posix-mode shells exit
+
+j. Fixed a problem when expanding $* in a context where word splitting is not
+   performed when IFS is NULL.
+
+k. Temp files used to store here documents are forced readable, no matter what
+   the user's umask says.
+
+l. Fixed a problem where an interrupted brace expansion could cause the shell
+   to attempt to free an invalid memory location.
+
+m. Make sure to check for any terminating signals after running a trap
+   handler; don't wait until the next time we process traps.
+
+n. Fixed a bug that caused "return" to act like a special builtin with respect
+   to variable assignments even when preceded by "command".
+
+o. POSIX-mode shells now return failure if the cd builtin fails due to the
+   absolute directory name being longer than PATH_MAX, instead of trying
+   again with a relative pathname.
+
+p. Fixed a problem with FUNCNAME occasionally being visible when not executing
+   a shell function.
+
+q. Fixed a problem with the expansions performed on the WORD in the case
+   command.
+
+r. Fixed a slight POSIX compatibility when removing "IFS whitespace" during
+   word splitting and the read builtin.
+
+s. Fixed a problem with expanding an array with subscript `*' when all the

+
+a. Fixed a bug with adding multibyte characters to an incremental search string.
+
+b. Fixed a bug with redoing text insertions in vi mode.
+

+
+g. Trap execution now honors the (internal) max invocations of `eval', since
+   traps are supposed to be executed as if using `eval'.
+
+h. The $_ variable doesn't change when the shell executes a command that forks.
+
+i. The `kill' builtin now supports -sSIGNAME and -nSIGNUM, even though

+
+j. POSIX mode now enables the `shift_verbose' option.
+
+4. New Features in Readline
+
+a. Readline now allows application-defined keymap names; there is a new public
+   function, rl_set_keymap_name(), to do that.
+
+b. The "Insert" keypad key, if available, now puts readline into overwrite
+   mode.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.0-beta, and
+the previous version, bash-5.0-alpha.
+
+1.  Changes to Bash
+
+a. Fixed a bug that allowed subshells to "inherit" enclosing loops -- this
+   is where POSIX says the subshell is not "enclosed" by the loop.
+
+b. Added more UTF-8-specific versions of multibyte functions, and optimized
+   existing functions if the current locale uses UTF-8 encoding.
+
+c. In POSIX mode, assignments preceding regular builtins should not persist
+   when the builtin completes.
+
+d. Added additional checks to special array assignment (e.g., BASH_ALIASES)
+   so it can't be used to bypass validity checks performed in other places.
+
+e. The `!!' history expansion now refers to the previous history entry as
+   expected, even if used on the second or subsequent line of a multi-line
+   history entry.
+
+f. Fixed a bug that could cause the shell to dereference a NULL pointer if
+   the environment (`environ') is set to NULL.
+
+g. Bash uses slightly better integer overflow handling for brace sequence
+   expansion on systems where ints are 32 bits and intmax_t is 64 bits.
+
+h. Fixed a bug setting attributes for a variable named as an argument to
+   `declare' that also appears as a nameref in the temporary environment.
+
+i. Fixed several bugs that could cause assignments to namerefs to create
+   variables with invalid names.
+
+j. Fixed a bug that could result in the SIGINT handler being set incorrectly
+   in asynchronous subshells.
+
+k. Fixed a bug that could cause `bash -t' to not execute the specified command.
+
+l. Fixed several bugs that caused the shell to operate on the wrong variable
+   when using namerefs with the same name as a global variable in shell
+   functions.
+
+m. Internal changes to how the shell handles variables with invalid names in
+   the initial environment and to prevent variables with invalid names from
+   being added to the environment instead of passing them on to children.
+
+n. Changes to make sure that an expansion that results in a quoted null string
+   is reflected in the expansion, even if the word expands to nothing.
+
+o. Changes to make sure that $* and ${array[*]} (and $@/${array[@]}) expand
+   the same way after the recent changes for POSIX interpretation 888.
+
+p. Saving and restoring the positional parameters at function entry and exit
+   is considerably more efficient; noticeably so when there are large numbers
+   of positional parameters.
+
+q. Fixed a bug that caused `lastpipe' and `pipefail' to return an incorrect
+   status for the pipeline if there was more than one external command in a
+   loop body appearing in the last pipeline element.
+
+r. Fixed a bug that caused value conversion errors with the printf builtin's
+   %u and %f conversion specifications and invalid constants.
+
+2.  Changes to Readline
+
+a. Added more UTF-8-specific versions of multibyte functions, and optimized
+   existing functions if the current locale uses UTF-8 encoding.
+
+b. Fixed a problem with bracketed-paste inserting more than one character and
+   interacting with other readline functions.
+
+c. Fixed a bug that caused the history library to attempt to append a history
+   line to a non-existent history entry.
+
+d. If using bracketed paste mode, output a newline after the \r that is the
+   last character of the mode disable string to avoid overwriting output.
+
+e. Fixes to the vi-mode `b', `B', `w', `W', `e', and `E' commands to better
+   handle multibyte characters.
+
+f. Fixed a redisplay problem that caused an extra newline to be generated on
+   accept-line when the line length is exactly the screenwidth.
+
+3.  New Features in Bash
+
+a. Bash no longer allows variable assignments preceding a special builtin that
+   changes variable attributes to propagate back to the calling environment
+   unless the compatibility level is 44 or lower.
+
+b. You can set the default value for $HISTSIZE at build time in config-top.h.
+
+c. The `complete' builtin now accepts a -I option that applies the completion
+   to the initial word on the line.
+
+d. The internal bash malloc now uses mmap (if available) to satisfy requests
+   greater than 128K bytes, so free can use mfree to return the pages to the
+   kernel.
+
+e. The shell doesn't automatically set BASH_ARGC and BASH_ARGV at startup
+   unless it's in debugging mode, as the documentation has always said, but
+   will dynamically create them if a script references them at the top level
+   without having enabled debugging mode.
+
+f. The localvar_inherit option will not attempt to inherit a value from a
+   variable of an incompatible type (indexed vs. associative arrays, for
+   example).
+
+g. The `globasciiranges' option is now enabled by default; it can be set to
+   off by default at configuration time.
+
+4.  New Features in Readline
+
+a. The history expansion library now understands command and process
+   substitution and extended globbing and allows them to appear anywhere in a
+   word.
+
+b. The history library has a new variable that allows applications to set the
+   initial quoting state, so quoting state can be inherited from a previous
+   line.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.0-alpha, and
+the previous version, bash-4.4-release.
+
+1.  Changes to Bash
+
+a. Fixed a bug that could cause traps in background jobs to give the terminal
+   to the wrong process group.
+
+b. Fixed a bug that caused `kill -l 0' to print an out-of-range error.
+
+c. Fixed a problem that could result in here-documents being displayed in
+   the wrong order.
+
+d. Fixed a number of out-of-bounds and free memory read errors found via
+   fuzzing.
+
+e. Fixed a subshell inheritance problem that could cause a subshell to wait for
+   the wrong process.
+
+f. Fixed a bug that caused SHLVL to be incremented one too many times when
+   creating subshells.
+
+g. A job dying due to SIGINT can now interrupt sourcing a file in a shell with

+
+l. The shell does a better job of saving multi-line history entries with
+   embedded comments.
+
+m. Fixed a bug that could cause quoted bracket expressions in regular expression
+   arguments to `[[' to not match correctly.
+
+n. Fixed a bug that could cause an IFS character in a word to result in an
+   extra '\001' character in the expansion.
+
+o. A trailing backslash in a glob pattern can match a trailing backslash in the
+   string.
+
+p. Fixed a memory leak in the process creation code path when job control is
+   enabled.
+
+q. Fixed a bug that caused `printf' to output broken surrogate pairs for
+   Japanese locales.
+
+r. Fixed a bug that caused a SIGINT generated from `kill' in a dot script to
+   kill an interactive shell.
+
+s. Fixed a bug that could cause the `read' builtin to not fully read a
+   multibyte character.
+
+t. Fixed a bug that could cause identifiers to be evaluated in conditional
+   arithmetic expressions even when evaluation is suppressed.
+
+u. Fixed a bug that could result in command substitution, when executed in a
+   context where word splitting is not performed, to leave a stray '\001'
+   character in the string.
+
+v. Fixed a bug that could cause history expansion to be disabled in a non-
+   interactive shell even if `-o histexpand' is supplied at startup.
+
+w. Fixed a bug that caused `read -N' to strip leading whitespace IFS characters.
+
+x. Fixed a bug that caused spurious tilde expansion in arithmetic expressions.
+
+y. If indirect expansion attempts to indirectly reference through an unset
+   variable, report an error.
+
+z. Added a guard to prevent the shell from looping while receiving an endless
+   stream of SIGTTIN at shell startup.
+
+aa. Fixed a bug with parsing here documents inside a command substitution when
+    looking for the closing delimiter.
+
+bb. Fixed a bug that caused printf to not quote all <blank> characters in the
+    current locale when using the `%q' format specifier.
+
+cc. Fixed a bug with bash's internal buffered I/O system that caused the input
+    pointer to not be reset when read(2) returned an EOF.
+
+dd. Bash now installs its SIGWINCH signal handler with SA_RESTART, so it will
+    not interrupt open/read/write system calls.
+
+ee. The ERR trap now reports line numbers more reliably.
+
+ff. The shell no longer tries to manipulate the terminal process group if a
+    command or process substitution is killed by SIGTERM when job control is
+    enabled.
+
+gg. Fixed a bug that caused extglob patterns to match filenames beginning with
+    a period.
+
+hh. File descriptors open for writing to here documents are no longer available
+    to subshells.
+
+ii. Make sure word completion doesn't perform command or process substitution.
+
+jj. Fixed a bug with parsing $$'...' inside a command substitution.
+
+kk. Fixed a bug that caused bash to remove backslash-newline pairs from the
+    body of a here-document with a quoted delimiter inside a command
+    substitution.
+
+ll. Fixed a bug that could cause the shell to hang when adding a pid to the
+    table of background process exit statuses.
+
+mm. Fixed a bug that could cause 0x01 characters to be doubled in the output
+    of process substitution.
+
+nn. Restricted shells now clear the hash table before making the PATH variable
+    read-only.
+
+oo. There are a number of changes to the expansion of $* and $@ in contexts
+    where word splitting does not occur (quoted and unquoted), with IFS set
+    to NULL or a non-standard value, mostly to deal with the consequences of
+    the behavior defined in Posix interpretation 888.
+
+pp. There are a number of changes to nameref variable handling to avoid
+    creating variables with invalid names.
+
+qq. A non-interactive posix mode shell no longer exits when an assignment
+    statement fails if the assignment is utimately being performed by the
+    `command' builtin.
+
+rr. When using character class names for globbing, don't allow case
+    insensitivity, even if nocaseglob is enabled.
+
+ss. Fixed a bug that allowed some redirections to stay in place if a later
+    redirection failed.
+
+tt. Fixed a bug in how command and process substitutions are recognized within
+    other parameter expansions.
+
+uu. Fixed a bug that caused bash to loop under certain circumstances when
+    performing arithmetic expansion on a variable whose value is an invalid
+    expression.
+
+vv. Fixed a bug that could cause bash to expand aliases inappropriately while
+    parsing compound commands like `case'.

+    various prompt strings.
+
+aaa. Fixed a bug that could cause a core dump if READLINE_LINE was unset
+     inside a shell function bound to a key sequence with `bind -x'.
+
+bbb. Fixed a bug that could cause bash to not read a token terminator correctly
+     if a command substitution was used inside an arithmetic `for' command.
+
+ccc. Fixed problems that could occur with a fatal arithmetic expansion error
+     in a context (like prompt expansion) where you can't jump back to the
+     top level.
+
+ddd. Expression errors in arithmetic `for' commands are treated more like
+     shell syntax errors.
+
+eee. Fixed a parser synchronization error resulting from a syntax error
+     followed immediately by an EOF.
+
+fff. When executing a shell function, the first line in the function ($LINENO)
+     is line 1 instead of line 0, as Posix requires.
+
+ggg. In Posix mode, bash will canonicalize the value of PWD it inherits from
+     the environment and use that to set its idea of the current directory.
+
+hhh. If LINENO is exported, bash needs to regenerate its value each time it
+     constructs the environment.
+
+iii. Fixed a bug with restoring the SIGINT handler when using `wait -n'.
+
+jjj. Make sure the `coproc' command returns an appropriate status if the NAME
+     argument is invalid.
+
+kkk. Fixed a problem with arithmetic expressions containing array references
+     that contain arithmetic expressions with syntax errors.
+
+lll. The `select' command and help builtin will use $COLUMNS before the window
+     size returned from the kernel as the terminal width.
+
+mmm. `read -n 0' and `read -N 0' now try a zero-length read in an attempt to
+     detect file descriptor errors.
+
+nnn. The `read' builtin now does a better job of acting on signals that don't
+     interrupt read(2).
+
+ooo. Fixed some cases where `printf -v' did not return failure status on a
+     variable assignment error.
+
+ppp. Fixed temporary environment propagation back to the current environment
+     so that it doesn't happen for special builtins run by the `command'
+     builtin.
+
+qqq. Fixed a bug when searching for the end of a here-document delimiter in a
+     command substitution.
+
+rrr. Fixed a bug that could cause `cd ${DIRSTACK[0]}' to fail.
+
+sss. Fixed a bug that could cause reserved words to not be recognized in a
+     for statement without the `in' inside a command substitution.
+
+ttt. Fixed a bug that could cause a double-free in a timed command with an
+     expansion error.
+
+uuu. Fixed a bug that could cause a core dump if a script switches from a UTF-8
+     locale to a different locale after displaying a lone surrogate character.
+
+vvv. Fixed cases where bash prematurely removed FIFOs attached to process
+     substitutions.
+
+www. Fixed a problem with calculating the size of the table that stores exit
+     statuses from background processes when the child process resource limit
+     is very large.
+
+xxx. Fixed a memory leak with functions using `return' when using FIFOs for
+     standard input.
+
+yyy. `wait' without arguments attempts to wait for all active process
+     substitution processes.
+
+zzz. Fixed a bug where an indirect parameter was subjected to word splitting
+     when trying to find the indirected variable name.
+
+aaaa. Fixed a bug that could allow restricted shell users to add commands to
+      the hash table.
+
+bbbb. When using the `!(patlist)' extended globbing operator, a filename
+      beginning with a `.' that doesn't match any of the patterns is not
+      returned as a match if leading dots must be matched explicitly.
+
+cccc. Fixed a bug that could cause line number and source file information for
+      a function definition to be incorrect if there are multiple definitions.
+
+dddd. Fixed a bug that could cause builtins like `readonly' to behave
+      differently when applied to arrays and scalar variables within functions.
+
+eeee. Fixed a bug that could cause alias expansion to add an extra space to
+      a quoted string that begins outside the alias expansion.
+
+ffff. Fixed a bug that could result in unwanted alias expansion after timing
+      the null command.
+
+gggg. Fixed a bug that could cause a core dump if a timestamp in a history
+      file overflowed a time_t.
+
+hhhh. Restricted shells can no longer redirect from /dev/tcp or /dev/udp, since
+      the kernel calls make those file descriptors read-write.
+
+iiii. Fixed a problem with splitting double-quoted words for programmable
+      completion when the double quote immediately follows another word
+      delimiter.
+
+jjjj. Fixed a bug resulting in a use-after-free if two file descriptors share
+      the same input buffer.
+
+kkkk. The error message resulting from ${x:?} and ${x?} now differs depending
+      on whether the variable is null or unset.
+
+llll. In Posix mode, the shell exits if a variable assignment fails and precedes
+      an empty simple command (after expansion).
+
+mmmm. Fixed a timing problem with SIGALRM that could cause the read builtin to
+      drop characters.
+
+nnnn. Added code to deal with kill(2) failing to send the shell a fatal signal
+      due to Linux pid namespace peculiarities.
+
+oooo. Fixed a bug that made \C-@ (NUL) unusable in key sequences used for
+      `bind -x' commands.
+
+pppp. Fixed a bug that could cause SIGINT recursion when running an external
+      command in a trap the shell takes after a command exits due to SIGINT.
+
+qqqq. Make sure the shell turns off job control before running the command-
+      not-found handle, so the command doesn't try to manipulate process
+      groups.
+
+rrrr. Fixed a problem with timing process substitutions that caused the shell
+      to print timing information for the calling command.
+
+ssss. Fixed a bug that caused backquotes in a here-document delimiter to mark
+      the delimiter as quoted (inhibiting expansion of the here-document
+      contents).
+
+tttt. Fixed several problems with 0x01 and 0x177 in case pattern lists and
+      conditional command pattern matches.
+
+uuuu. Fixed a bug that could cause the pattern matching engine to not recognize
+      locale-specific character classes.
+
+vvvv. The auto-configuration now tests for /dev/stdin and /dev/fd independently.
+
+wwww. The `globstar' code now skips over symbolic links to directories,
+      preventing them from being scanned twice.
+
+xxxx. When running `bind -x' commands, bash now sets READLINE_POINT based on
+      the number of characters in the readline line buffer, not the number of
+      bytes.
+
+yyyy. Fixed a problem that could cause recursive trap evaluation of the RETURN
+      trap when using `eval return'.
+
+zzzz. Fixed a bug with expanding 0x01 in an unquoted here-document.
+
+aaaaa. The process substitution code now closes and unlinks FIFOs when the
+       process on the other side exits, in order to prevent SIGPIPE or
+       waiting until a FIFO opened for read has a writer.
+
+bbbbb. Fixed a bug with recursive calls to the parser overwriting the token in
+       an {id}>foo construct.
+
+ccccc. After a Posix discussion, the pattern matching engine just skips over
+       invalid character classes in bracket expressions, instead of matching
+       them like individual characters in the expression.
+
+ddddd. Fixed a posix-mode problem with variable scoping when creating variables
+       from assignment statements preceding special builtins.
+
+eeeee. Fixed a bug that could cause patterns containing backslashes to not be
+       run through the pattern matching engine.
+
+fffff. Fixed a bug that could cause redirections to compound commands to not
+       be `undone' if the file descriptor in the redirection was closed when
+       the redirection was initially processed.
+
+ggggg. Fixed a bug that could cause buffer corruption when using `bind -x' in
+       a command execute as a result of a key binding installed by `bind -x'.
+
+2.  Changes to Readline
+
+a. Added a guard to prevent nested macros from causing an infinite expansion
+   loop.
+
+b. Instead of allocating enough history list entries to hold the maximum list
+   size, cap the number allocated initially.
+
+c. Added a strategy to avoid allocating huge amounts of memory if a block of
+   history entries without timestamps occurs after a block with timestamps.
+
+d. Added support for keyboard timeouts when an ESC character is the last
+   character in a macro.
+
+e. There are several performance improvements when in a UTF-8 locale.
+
+f. Readline does a better job of preserving the original set of blocked
+   signals when using pselect() to wait for input.
+
+g. Fixed a bug that caused multibyte characters in macros to be mishandled.
+
+h. Fixed several bugs in the code that calculates line breaks when expanding
+   prompts that span several lines, contain multibyte characters, and contain
+   invisible character seqeuences.
+
+i. Fixed several bugs in cursor positioning when displaying lines with prompts
+   containing invisible characters and multibyte characters.
+
+j. When performing case-insensitive completion, Readline no longer sorts the
+   list of matches unless directed to do so.
+
+k. Fixed a problem with key sequences ending with a backslash.
+
+l. Fixed out-of-bounds and free memory read errors found via fuzzing.
+
+m. Fixed several cases where the mark was set to an invalid value.
+
+n. Fixed a problem with the case-changing operators in the case where the
+   lower and upper case versions of a character do not have the same number
+   of bytes.
+
+o. Handle incremental and non-incremental search character reads returning EOF.
+
+p. Handle the case where a failing readline command at the end of a multi-key
+   sequence could be misinterpreted.
+
+q. The history library now prints a meaningful error message if the history
+   file isn't a regular file.
+
+r. Fixed a problem with vi-mode redo (`.') on a command when trying to replace
+   a multibyte character.
+
+s. The key binding code now attempts to remove a keymap if a key unbinding
+   leaves it empty.
+
+t. Fixed a line-wrapping issue that caused problems for some terminal
+   emulators.
+
+u. If there is a key bound to the tty's VDISCARD special character, readline
+   disables VDISCARD while it is active.
+
+v. Fixed a problem with exiting bracketed paste mode on terminals that assume
+   the bracketed paste mode character sequence contains visible characters.
+
+w. Fixed a bug that could cause a key binding command to refer to an
+   uninitialized variable.
+
+3.  New Features in Bash
+
+a. The `wait' builtin can now wait for the last process substitution created.
+
+b. There is an EPOCHSECONDS variable, which expands to the time in seconds
+   since the Unix epoch.
+
+c. There is an EPOCHREALTIME variable, which expands to the time in seconds
+   since the Unix epoch with microsecond granularity.
+
+d. New loadable builtins: rm, stat, fdflags.
+
+e. BASH_ARGV0: a new variable that expands to $0 and sets $0 on assignment.
+
+f. When supplied a numeric argument, the shell-expand-line bindable readline
+   command does not perform quote removal and suppresses command and process
+   substitution.
+
+g. `history -d' understands negative arguments: negative arguments offset from
+   the end of the history list.
+
+h. The `name' argument to the `coproc' reserved word now undergoes word
+   expansion, so unique coprocs can be created in loops.
+
+i. A nameref name resolution loop in a function now resolves to a variable by
+   that name in the global scope.
+
+j. The `wait' builtin now has a `-f' option, which signifies to wait until the
+   specified job or process terminates, instead of waiting until it changes
+   state.
+
+k. There is a define in config-top.h that allows the shell to use a static
+   value for $PATH, overriding whatever is in the environment at startup, for
+   use by the restricted shell.
+
+l. Process substitution does not inherit the `v' option, like command
+   substitution.
+
+m. If a non-interactive shell with job control enabled detects that a foreground
+   job died due to SIGINT, it acts as if it received the SIGINT.
+
+n. The SIGCHLD trap is run once for each exiting child process even if job
+   control is not enabled when the shell is in Posix mode.
+
+o. A new shopt option: localvar_inherit; if set, a local variable inherits the
+   value of a variable with the same name at the nearest preceding scope.
+
+p. `bind -r' now checks whether a key sequence is bound before binding it to
+   NULL, to avoid creating keymaps for a multi-key sequence.
+
+q. A numeric argument to the line editing `operate-and-get-next' command
+   specifies which history entry to use.
+
+r. The positional parameters are now assigned before running the shell startup
+   files, so startup files can use $@.
+
+s. There is a compile-time option that forces the shell to disable the check
+   for an inherited OLDPWD being a directory.
+
+t. The `history' builtin can now delete ranges of history entries using
+   `-d start-end'.
+
+u. The `vi-edit-and-execute-command' bindable readline command now puts readline
+   back in vi insertion mode after executing commands from the edited file.
+
+v. The command completion code now matches aliases and shell function names
+   case-insensitively if the readline completion-ignore-case variable is set.
+
+w. There is a new `assoc_expand_once' shell option that attempts to expand
+   associative array subscripts only once.
+
+x. The shell only sets up BASH_ARGV and BASH_ARGC at startup if extended
+   debugging mode is active. The old behavior of unconditionally setting them
+   is available as part of the shell compatibility options.
+
+y. The `umask' builtin now allows modes and masks greater than octal 777.
+
+z. The `times' builtin now honors the current locale when printing a decimal
+   point.
+
+aa. There is a new (disabled by default, undocumented) shell option to enable
+    and disable sending history to syslog at runtime.
+
+4.  New Features in Readline
+
+a. Non-incremental vi-mode search (`N', `n') can search for a shell pattern, as
+   Posix specifies (uses fnmatch(3) if available).
+
+b. There are new `next-screen-line' and `previous-screen-line' bindable
+   commands, which move the cursor to the same column in the next, or previous,
+   physical line, respectively.
+
+c. There are default key bindings for control-arrow-key key combinations.
+
+d. A negative argument (-N) to `quoted-insert' means to insert the next N
+   characters using quoted-insert.
+
+e. New public function: rl_check_signals(), which allows applications to
+   respond to signals that readline catches while waiting for input using
+   a custom read function.
+
+f. There is new support for conditionally testing the readline version in an
+   inputrc file, with a full set of arithmetic comparison operators available.
+
+g. There is a simple variable comparison facility available for use within an
+   inputrc file. Allowable operators are equality and inequality; string
+   variables may be compared to a value; boolean variables must be compared to
+   either `on' or `off'; variable names are separated from the operator by
+   whitespace.

+    number of any signal readline has caught but not yet handled.
+
+b.  New application-settable variable: rl_persistent_signal_handlers: if set
+    to a non-zero value, readline will enable the readline-6.2 signal handler

+    rl_callback_handler_install is called and removed removed when a complete
+    line has been read.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.4-beta2, and
+the previous version, bash-4.4-rc1.

+
+b.  Fixed a bug that caused subshells to free trap strings associated with
+    inherited signals.

+    associated with enabling an option, instead of just marking the option
+    as enabled.
+
+d.  Fixed a bug that allowed assignments to BASH_CMDS when the shell was in
+    restricted mode.
+
+e.  Fixed a bug caused by an accidental omission of part of the original patch

+    circuiting.
+
+i.  Fixed a memory leak in the code that removes duplicate history entries.
+
+j.  There are a number of bug fixes to coproc, mapfile, declare, unset,
+    and assignment statements that prevent nameref variables from creating
+    and unsetting variables with invalid names.
+
+k.  Fixed a bug that caused variables to be inadvertently marked as both an
+    associative and an indexed array.
+
+l.  Fixed a bug that caused `bash -c' to not run a trap specified in the
+    command string.
+
+j.  There are a number of bug fixes to coproc, mapfile, declare, and assignment
+    statements that prevent nameref variables from overwriting or modifying
+    attributes of readonly variables.
+
+k.  Fixed a bug that caused command substitution to attempt to set the
+    terminal's process group incorrectly.
+    
+l.  Fixed a bug that could cause prompt string expansion to display error
+    messages when the `nounset' shell option is set.
+
+m.  Fixed a bug that caused "$@" to not expand to an empty string under the
+    circumstances when Posix says it should ("${@-${@-$@}}").
+
+n.  Fixed several bugs caused by referencing nameref variables whose values
+    are names of unset variables (or names that are valid for referencing
+    but not assignment), including creating variables in the temporary
+    environment.
+
+o.  Function tracing and error tracing are disabled if --debugger is supplied
+    at startup but the shell can't find the debugger start file.
+
+p.  Fixed a bug when IFS is used as the control variable in a for statement.
+
+q.  Fixed a bug with SIGINT received by a command substitution in an interactive
+    shell.
+
+r.  The checks for nameref variable self-references are more thorough.
+
+s.  Fixed several bugs with multi-line aliases.
+
+t.  Fixed `test' to handle the four-argument case where $1 == '(' and

+u.  Fixed a bug in the expansion of $* in the cases where word splitting is
+    not performed.
+
+v.  Fixed a bug in execution of case statements where IFS includes the
+    pattern matching characters.
+
+2.  Changes to Readline
+
+a.  When refreshing the line as the result of a key sequence, Readline attempts
+    to redraw only the last line of a multiline prompt.
+
+b.  Fixed an issue that caused completion of git commands to display
+    incorrectly when using colored-completion-prefix.
+
+c.  Fixed several redisplay bugs having to do with multibyte characters and
+    invisible characters in prompt strings.
+
+3.  New Features in Bash
+
+a.  Value conversions (arithmetic expansions, case modification, etc.) now
+    happen when assigning elements of an array using compound assignment.
+
+b.  There is a new option settable in config-top.h that makes multiple
+    directory arguments to `cd' a fatal error.
+
+c.  Bash now uses mktemp() when creating internal temporary files; it produces
+    a warning at build time on many Linux systems.
+
+4.  New Features in Readline
+
+a.  The default binding for ^W in vi mode now uses word boundaries specified
+    by Posix (vi-unix-word-rubout is bindable command name).
+
+b.  rl_clear_visible_line: new application-callable function; clears all
+    screen lines occupied by the current visible readline line.
+
+c.  rl_tty_set_echoing: application-callable function that controls whether
+    or not readline thinks it is echoing terminal output.
+
+d.  Handle >| and strings of digits preceding and following redirection
+    specifications as single tokens when tokenizing the line for history
+    expansion.
+
+e.  Fixed a bug with displaying completions when the prefix display length
+    is greater than the length of the completions to be displayed.
+
+f.  The :p history modifier now applies to the entire line, so any expansion
+    specifying :p causes the line to be printed instead of expanded.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.4-rc1, and
+the previous version, bash-4.4-beta.
+
+1.  Changes to Bash
+
+a.  Fixed several problems with bash completion not special-casing bash syntax
+    constructs.

+c.  Fixed a bug that caused prompt expansion to loop when PS1 contained a
+    syntax error.
+
+d.  Fixed a bug that caused the ${array[@]@A} expansion to split the results
+    even when double-quoted.
+
+e.  There is a new implementation of the code that saves the last CHILD_MAX
+    exited background pids so their status can be queried later.
+
+f.  Bash-4.4 can now be configured and built on very old versions of Solaris 2.
+
+g.  Fixed problems with --help support for several builtins.
+
+h.  Fixed values added to BASH_SOURCE and BASH_LINENO for functions inherited
+    from the environment.

+    under certain circumstances.
+
+j.  Fixed a bug that caused `fc' to return an incorrect exit status when
+    executing commands from the history list.
+
+k.  Fixed a bug that caused the shell to exit when a process substitution
+    received a SIGINT when run in certain terminal emulators.
+
+l.  EXECIGNORE now honors the setting of `extglob' when attempting to match
+    executable names.
+
+m.  Fixed a bug where `return' used the wrong exit status when executed in a
+    DEBUG trap.
+
+n.  Fixed a bug that caused a command containing a here-document and an escaped
+    newline to be stored in the history list incorrectly.
+
+o.  Fixed a bug that caused set -e to be honored in cases of builtins invoking
+    other builtins when it should be ignored.
+
+p.  Fixed a bug that caused `readonly' and `export' to create local array
+    variables when used within shell functions.
+
+q.  Fixed a bug that allowed subshells begun to execute process substitutions
+    to have access to the command's temporary environment.
+
+r.  Fixed a bug that could cause the shell to dump core when receiving a
+    SIGCHLD for which a trap has been set while running in posix mode.
+
+s.  Fixed a bug that caused bash to not restore BASH_ARGC, BASH_ARGV,
+    BASH_SOURCE, BASH_LINENO, and FUNCNAME if the shell received a SIGINT
+    while reading commands from a file while executing  `.'.
+
+t.  Fixed a bug that caused the `-o history' option to have no effect when
+    supplied on the command line when starting a new shell.
+
+u.  Fixed a bug that caused history expansions occurring in command
+    substitutions to not be performed.
+
+v.  Fixed a bug that caused `eval' run in a non-interactive shell to disable
+    history expansion for the remainder of the shell script, even if the script
+    had previously enabled it.
+
+w.  Fixed a bug that caused "$@" to not expand to multiple words when IFS is set
+    to the empty string.
+
+x.  Fixed a bug that caused process and command substitution to inherit output
+    buffered in the stdio library but not written.
+
+y.  Fixed a bug that caused a terminating signal received during `echo' to run
+    an exit trap in a signal handler context.
+
+z.  Fixed a bug that caused a builtin command containing a process substitution
+    to return the wrong exit status.
+
+aa. Fixed a bug that caused `()' subshells with piped input to incorrectly
+    redirect the standard input of some of the commands in the subshell from
+    /dev/null.
+
+bb. The history builtin now uses more descriptive error messages for missing or
+    invalid timestamps.
+
+2.  Changes to Readline
+
+a.  The history file writing functions only attempt to create and use a backup
+    history file if the history file exists and is a regular file.
+
+b.  Fixed an out-of-bounds read in readline's internal tilde expansion
+    interface.
+
+c.  Fixed several redisplay bugs with prompt strings containing multibyte
+    and non-visible characters whose physical length is longer than the screen
+    width.
+
+d.  Fixed a redisplay bug with prompt strings containing invisible characters
+    whose physical length exceeds the screen width and using incremental search.
+
+e.  Readline prints more descriptive error messages when it encounters errors
+    while reading an inputrc file.
+
+f.  Fixed a bug in the character insertion code that attempts to optimize
+    typeahead when it reads a character that is not bound to self-insert and
+    resets the key sequence state.
+
+3.  New Features in Bash
+
+a.  BASH_COMPAT and FUNCNEST can be inherited and set from the shell's initial
+    environment.
+
+b.  inherit_errexit: a new `shopt' option that, when set, causes command
+    substitutions to inherit the -e option.  By default, those subshells disable
+    -e.  It's enabled as part of turning on posix mode.
+
+c.  New prompt string: PS0.  Expanded and displayed by interactive shells after
+    reading a complete command but before executing it.
+
+d.  Interactive shells now behave as if SIGTSTP/SIGTTIN/SIGTTOU are set to
+    SIG_DFL when the shell is started, so they are set to SIG_DFL in child
+    processes.
+
+e.  Posix-mode shells now allow double quotes to quote the history expansion
+    character.
+
+f.  OLDPWD can be inherited from the environment if it names a directory.
+
+g.  Shells running as root no longer inherit PS4 from the environment, closing
+    a security hole involving PS4 expansion performing command substitution.
+
+h.  If executing an implicit `cd' when the `autocd' option is set, bash will
+    now invoke a function named `cd' if one exists before executing the `cd'
+    builtin.
+
+4.  New Features in Readline
+
+a.  If an incremental search string has its last character removed with DEL,
+    the resulting empty search string no longer matches the previous line.
+
+b.  If readline reads a history file that begins with `#' (or the value of
+    the history comment character) and has enabled history timestamps, the
+    history entries are assumed to be delimited by timestamps.  This allows
+    multi-line history entries.
+
+c.  Readline now throws an error if it parses a key binding without a
+    terminating `:' or whitespace.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.4-beta, and
+the previous version, bash-4.4-alpha.

+
+e.  Fixed a bug that caused the && and || operators to be incorrectly optimized.
+
+f.  The shell now undoes redirections before exiting the shell when the `-e'
+    option is enabled, and a shell function fails.
+
+g.  History expansion now skips over the history expansion character in command
+    and process substitution.
+
+h.  Fixed a bug that caused stray '\001' characters to be added to the output
+    of `declare -p'.
+
+i.  Fixed a memory leak when processing declare commands that perform compound
+    array assignments.
+
+j.  Fixed a bug that could cause the shell to crash when reading input from a
+    file and the limit on open file descriptors is high.
+
+k.  Fixed a bug that caused the ERR and RETURN traps to be unset if they were
+    set in a shell function but unset previously.
+
+l.  Fixed a bug that caused several signals to be ignored if `exec' failed in
+    an interactive shell.
+
+m.  A posix-mode non-interactive shell now considers a parameter expansion error
+    to be a fatal error.
+
+n.  The `time' command now prints timing statistics for failed commands when

+
+o.  Fixed a bug that caused the shell to crash when attempting to indirectly
+    expand a shell variable with an invalid name.
+
+p.  Fixed a bug that caused the shell to crash when running a trap containing
+    a process substitution.
+
+q.  Bash now prints the keyword `function' before a function with the same name
+    as a reserved word when using `declare -f' to avoid parse errors when
+    reusing the output as input.
+
+r.  Fixed a bug that caused the shell to crash when using declare -g to attempt
+    to redefine an existing global indexed array variable as an associative
+    array.
+
+s.  Fixed a memory leak that occurred when interrupting brace expansions
+    generating a sequence.
+
+t.  Fixed a bug that resulted in alias expansion in redirections.
+
+u.  The `declare -a' and `declare -A' commands now print fewer warnings when
+    attempting to create and initialize an array at the same time, but
+    relying on word expansions to construct the compound assignment.
+
+v.  The `help' builtin now behaves better in locales where each wide
+    character occupies more than one display column.
+
+w.  The `read' builtin no longer has a possible race condition when a timeout
+    occurs.
+
+x.  Fixed several expansion problems encountered when IFS="'".
+
+y.  Fixed a problem with the expansion of $'\c?'.
+
+z.  Bash no longer splits the expansion of here-strings, as the documentation
+    has always said.
+
+aa. Bash now puts `s' in the value of $- if the shell is reading from standard
+    input, as Posix requires.
+
+bb. Fixed a bug that caused the shell to crash if invoked with a NULL
+    environment.
+
+cc. The shell now only trusts an inherited value for $PWD if it begins with a
+    `/'.
+

+
+ee. Fixed a bug that could cause the shell to crash when processing nested here
+    documents inside a command substitution.
+
+ff. Array keys and values are now displayed using $'...' quoting where
+    appropriate.

+
+ii. Fixed a bug that could cause the shell to crash if variable indirection
+    resulted in a NULL variable.
+
+jj. Fixed a bug that could cause the shell to crash if a long string contained
+    multiple unterminated parameter expansion constructs.
+
+kk. Improved the code that acts on SIGINT received while waiting for a child
+    process only if the child exits due to SIGINT.
+
+ll. $BASH_SUBSHELL now has more consistent values in asynchronous simple
+    commands.
+
+2.  Changes to Readline
+

+    likely to collide with files.
+
+b.  Fixed a bug that caused vi-mode character search to misbehave when
+    running in callback mode.
+
+c.  Fixed a bug that caused output to be delayed when input is coming from a
+    macro in vi-mode.
+
+d.  Fixed a bug that caused the vi-mode `.' command to misbehave when redoing
+    a multi-key key sequence via a macro.
+
+e.  Fixed a bug that caused problems with applications that supply their own
+    input function when performing completion.
+
+f.  When read returns -1/EIO when attempting to read a key, return an error
+    instead of line termination back to the caller.
+
+g.  Updated tty auditing feature based on patch from Red Hat.
+
+h.  Fixed a bug that could cause the history library to crash on overflows
+    introduced by malicious editing of timestamps in the history file.
+
+3.  New Features in Bash
+
+a.  `make install' now installs the example loadable builtins and a set of
+    bash headers to use when developing new loadable builtins.
+
+b.  `enable -f' now attempts to call functions named BUILTIN_builtin_load when
+    loading BUILTIN, and BUILTIN_builtin_unload when deleting it.  This allows
+    loadable builtins to run initialization and cleanup code.
+
+c.  There is a new BASH_LOADABLES_PATH variable containing a list of directories
+    where the `enable -f' command looks for shared objects containing loadable
+    builtins.
+
+d.  The `complete_fullquote' option to `shopt' changes filename completion to
+    quote all shell metacharacters in filenames and directory names.
+
+e.  The `kill' builtin now has a `-L' option, equivalent to `-l', for
+    compatibility with Linux standalone versions of kill.
+
+4.  New Features in Readline
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.4-alpha, and
+the previous version, bash-4.3-release.
+
+1.  Changes to Bash
+
+a.  A bug that caused pipelines to be corrupted while running the DEBUG trap
+    was fixed.
+
+b.  A bug that accidentally omitted the `-R' unary operator from `test' was
+    fixed.
+
+c.  A bug that could cause the shell to not restore the terminal's process
+    group on shell exit was fixed.
+
+d.  Several changes were made to programmable completion to accommodate
+    assumptions made by the bash-completion package.
+
+e.  Bash no longer inhibits C-style escape processing ($'...') while performing
+    pattern substitution word expansions.
+
+f.  Fixed a bug that caused `return' executed from a trap handler to use the
+    wrong return status when one was not supplied as an argument.
+
+g.  In Posix mode, defining a function with the same name as a special
+    builtin is now an error, fatal only when the shell is not interactive.
+
+h.  Fixed a bug that caused compound array assignments to discard unset or null
+    variables used as subscripts, thereby making it appear as if the index was
+    not present.
+
+i.  Fixed a bug that caused extended glob patterns to incorrectly match
+    filenames with a leading `.'.
+
+j.  Fixed a bug involving sign extension when reallocating the input line
+    after a history expansion, causing segmentation faults.
+
+k.  Bash now does a better job at identifying syntax errors during word
+    completion and tailoring completion appropriately.
+
+l.  Bash now uses the current locale's decimal point in command timing output.
+
+m.  Fixed a bug that caused segmentation faults while reading here documents if
+    PS2 contains a command substitution.
+
+n.  There are several changes to how $@ is expanded when unquoted but in a
+    context where word splitting is not performed (e.g., on the rhs of an
+    assignment or in a conditional command).
+
+o.  Bash now quotes command hash table entries that contain shell metacharacters
+    when displaying hash table contents.
+
+p.  Fixed a potential file descriptor leak when dup2() fails while performing a
+    redirection.
+
+q.  Fixed a bug that caused directory names evaluated during word completion to
+    be dequoted twice.
+
+r.  Fixed several bugs which could result in indirect variable expansion and
+    namerefs creating variables with invalid names or referencing variables
+    set to the empty string.
+
+s.  Fixed a bug that caused bash to not expand $0 in word expansions where it
+    should.
+
+t.  Fixed a bug that caused bash to perform process substitution if <(
+    appeared inside an arithmetic context.
+
+u.  Fixed a bug in extglob pattern parsing that caused slashes in the pattern
+    to be confused as directory names.
+
+v.  Fixed several bugs with treatment of invisible variables (variables with
+    attributes that are unset because they have never been assigned values).
+
+w.  Fixed a bug that caused the `read' builtin to not clean up readline's
+    state when using the -e and -t options together and the read timed out.
+
+x.  Fixed a bug that caused the shell to exit with the wrong (but non-zero)
+    value if a command was not found or was not executable.
+
+y.  Fixed a bug that caused the `time' reserved word to not be recognized as
+    such in all contexts where it should have been.
+
+z.  Fixed a bug that caused the shell to close process substitution file
+    descriptors when executing a script without the `#!' leading line.
+
+aa. Fixed a typo that caused the `compat42' shell option to set the wrong
+    compatibility level.
+
+bb. The shell now handles process substitution commands with embedded
+    parentheses the same way as it does when parsing command substitution.
+
+cc. Fixed a bug that caused nested pipelines and the `lastpipe' shell option
+    to produce core dumps.
+
+dd. Fixed a bug that caused patterns containing `*' to match pathnames in cases
+    where slashes must be matched explicitly.
+
+ee. Fixed a problem with patterns containing `:' in colon-separated variables
+    like GLOBIGNORE. 
+
+ff. Fixed a bug that caused indirect variable expansion using indexed arrays to
+    always use index 0.
+
+gg. Fixed a parsing problem that caused quoted newlines immediately following a
+    command substitution to be mishandled in certain cases.
+
+hh. Fixed a potential buffer overflow on systems without locale_charset or the
+    bash replacement.
+
+ii. Fixed a bug that caused background processes to modify the terminal's
+    process group under certain circumstances.
+
+jj. Asynchronous commands now always set $? to 0 and are not affected by
+    whether or not the command's exit status is being inverted.
+
+kk. Fixed a problem that caused a line ending with an escaped newline and
+    containingh a prior `eval' to be incorrectly parsed.
+
+ll. Fixed an issue with programmable completion and `!' in extglob patterns
+    used as arguments to `compgen -X'.
+
+mm. Word completion now treats the two-character token `>|' as requiring
+    filename expansion.
+
+nn. Bash no longer expands tildes in $PATH elements while in Posix mode.
+
+oo. Fixed a bug that caused bash to not clean up readline's state, including
+    the terminal settings, if it received a fatal signal while in a readline()
+    call (including `read -e' and `read -s').
+
+pp. Fixed bug that caused importing shell functions from the environment to
+    execute additional commands following the function.
+
+qq. Fixed a bug that caused the parser to return a lookahead character pushed
+    back by a previous call, even when on another line.
+
+rr. Fixed a bug that caused many here-documents or many nested case statements
+    to overflow an internal stack.
+
+ss. Changed the way bash encodes exported functions for inclusion in the
+    environment to avoid name collisions with valid variable names and to
+    indicate that they are exported functions.
+
+tt. Fixed a bug that could result in an invalid memory access when processing
+    a here document delimited by end of file or end of string.
+
+uu. Fixed a bug that could cause an invalid memory access if a command was run
+    before initializing the job control framework.
+
+vv. When in Posix mode, bash prints shell function definitions as Posix
+    specifies them, without the leading `function' keyword.
+
+ww. The variable attribute display builtins no longer display variables with
+    invalid names that were imported from the environment.
+
+xx. Fixed a bug that could allow `break' or `continue' executed from shell
+    functions to affect loops running outside of the function.
+
+yy. Fixed a bug that could cause a restricted shell to attempt to import shell
+    functions from the environment.
+
+zz. The shell now allows double-quoted identifiers in arithmetic expressions.
+
+aaa. Fixed a bug that could allow scalar variables subscripted using [@] in
+     word expansions to be incorrectly quoted.
+
+bbb. The shell now makes sure to ignore SIGTSTP/SIGTTIN/SIGTTOU in child
+     processes if they were ignored at shell startup, even if job control is
+     in effect.
+
+ccc. Fixed a bug that could cause $* to be split on spaces when IFS is set to
+     the empty string.
+
+ddd. Posix says that expanding $* in a pattern context where the expansion is
+     double-quoted should not treat $* as if it were double quoted.
+
+eee. Bash now restores getopts' internal state between calls to getopts even if
+     a shell function declares a local copy of OPTIND.
+
+fff. Fixed a bug that could cause `history -r' or `history -n' to read identical
+     lines from the history file more than once.
+
+ggg. The commands executed by `bind -x' now redisplay at most the final line
+     of a multi-line prompt, and those commands may return 124 to indicate that
+     the entire prompt should be redrawn.
+
+hhh. Fixed a bug that could cause `mapfile' to create variables with invalid
+     names.
+
+iii. The shell only goes into debugging mode when --debugger is supplied if
+     the debugger initialization file is present.
+
+jjj. Fixed a bug that disallowed an assignment to (implicit) subscript 0 of an
+     existing array in a declare command that set the readonly attribute.
+
+kkk. Fixed a bug that inadvertently allowed assignments to FUNCNAME to disable
+     its special status.
+
+lll. Appending to an existing array variable using the compound assignment
+     syntax (var+=(aaa)) should not affect assignments to existing subscripts
+     appearing in the compound assignment.
+
+mmm. Fixed a bug that could cause the shell to crash when a variable with a
+     null value was passed in the temporary environment and the variable's
+     attributes are modified using `declare' while performing a redirection.
+
+nnn. Fixed a bug in printf so that a missing precision specifier after a `.'
+     is treated as 0.
+
+ooo. Fixed a bug that attempted to use the internal command timing to time
+     pipeline components if the pipeline elements are separated by newlines.
+
+ppp. Fixed a bug that caused `declare -al foo=(ONE TWO THREE)' to not lowercase
+     the values on assignment.
+
+qqq. Bash does a better job of determining whether or not files are executable
+     when running on Windows, since the X_OK flag to access(2) is not supported.
+
+rrr. Fixed a bug that caused some of the shell's internal traps (e.g., ERR) to
+     be interrupted (and leave incorrect state) by pending SIGINTs.
+
+sss. Fixed a bug in the bash interface to history expansion to avoid attempting
+     expansion if the history expansion character occurs in a command
+     substitution.
+
+ttt. Fixed a bug that caused the select command to crash if the REPLY variable
+     ends up empty (e.g., if it's made readonly)
+
+uuu. Bash handles backslash-quoting of multibyte characters better when quoting
+     output that is intended to be reused.
+
+vvv. System-specific changes for: Windows, Cygwin.
+
+www. Fixes for upper and lower-casing multibyte characters, some locales have
+     characters whose upper and lowercase versions have different numbers of
+     bytes.
+
+xxx. Fixed a bug that caused the ERR trap in a shell function to have the
+     wrong value for $LINENO.
+
+yyy. Fixed a bug that resulted in incorrect quoting of regexps for the =~
+     operator when an open brace appears without a close brace.
+
+zzz. Fixed a bug in the array unset operation that caused it to attempt to
+     parse embedded single and double quotes.
+
+aaaa. Fixed a bug that caused $* to not expand with the first character of
+      $IFS as a separator in a context where word splitting will not take
+      place.
+
+bbbb. Fixed two bugs that could cause the shell to dereference a null pointer
+      while attempting to print an error message from arithmetic expansion.
+
+cccc. Fixed a bug that resulted in short-circuited evaluation when reading
+      commands from a string ending in an unquoted backslash, or when sourcing
+      a file that ends with an unquoted backslash.
+
+dddd. Fixed a bug that resulted in the no-fork optimization not cleaning up
+      any FIFOs created by process substitution.
+
+eeee. If the -T option is not set, allow the source builtin and shell functions
+      to set a DEBUG trap that persists after the sourced file or function
+      returns, instead of restoring the old (unset) value unconditionally.
+
+ffff. Fixed a bug that caused redirections to not be undone on some syntax
+      errors, e.g., when parsing a command substitution.
+
+gggg. Bash only adds asynchronous commands to the table of background pids
+      whose status it remembers, to avoid it growing too large during scripts
+      that create and reap large numbers of child processes.  This means that
+      `wait' no longer works on synchronous jobs, but $? can be used to get
+      the exit status in those cases.
+
+hhhh. Bash now checks whether or not a shell script argument is a directory
+      before trying to open it; Posix says implementations may allow open(2)
+      on a directory.
+
+iiii. Fixed a bug that could cause the shell to set the terminal's process
+      group to a background process group when running as part of a pipeline.
+
+jjjj. Made a few changes to strings to avoid possible potential negative effects
+      caused by malicious translations.
+
+kkkk. Fixed a bug that caused the `unset' builtin to continue to treat its
+      arguments as functions after unsetting a function when invoked with no
+      options.
+
+llll. Fixed a bug that would not replace empty strings using pattern
+      substitution even if the pattern matched the empty string.
+
+mmmm. Fixed a bug with word completion that prevented some characters from
+      being backslash-quoted (backquote, dollar sign).
+
+nnnn. Fixed a bug that prevented a command from the history re-executed by the
+      `fc' builtin from setting verbose mode.
+
+oooo. Fixed a bug that caused the shell to not enable and disable function
+      tracing with changes to the `extdebug' shell option.
+
+pppp. Fixed a bug that caused assignments to nameref variables pointing to
+      unset variables with attributes but no values to create variables with
+      incorrect names.
+
+qqqq. Fixed a bug that caused `unset' on nameref variables (without -n) to
+      unset the wrong variable under certain circumstances.
+
+rrrr. Fixed a bug that caused close braces occurring in brace expansions within
+      command substitutions to incorrectly terminate parameter expansions.
+
+ssss. Fixed a bug that caused `command -p' to temporarily alter $PATH.
+
+tttt. Fixed a bug that caused interactive shells compiled without job control
+      to return incorrect status values for child processes when running a
+      single command that creates enough children to use the entire PID space.
+
+uuuu. `esac' should not be recognized as a reserved word when it appears as the
+      second or later pattern in a case statement pattern list.
+
+vvvv. Fixed a bug that caused the completion code to read past the end of the
+      readline line buffer while skipping assignment statements to find the
+      command name.
+
+wwww. Fixed a bug that caused case statements within loops contained in a
+      command substitution to be parsed incorrectly.
+
+xxxx. Fixed a bug that could cause SIGCHLD handling to be delayed after
+      running `wait' with no arguments and interrupting it with ^C without
+      a trap handler installed.
+
+2.  Changes to Readline
+
+a.  A bug that caused vi-mode `.' to be unable to redo `c', `d', and `y'
+    commands with modifiers was fixed.
+
+b.  Fixed a bug that caused callback mode to dump core when reading a
+    multiple-key sequence (e.g., arrow keys).
+
+c.  Fixed a bug that caused the redisplay code to erase some of the line when
+    using horizontal scrolling with incremental search.
+
+d.  Readline's input handler now performs signal processing if read(2) is
+    interrupted by SIGALRM or SIGVTALRM.
+
+e.  Fixed a problem with revert-all-at-newline freeing freed memory.
+
+f.  Clarified the documentation for the history_quotes_inhibit_expansion
+    variable to note that it inhibits scanning for the history comment
+    character and that it only affects double-quoted strings.
+
+g.  Fixed an off-by-one error in the prompt printed when performing searches.
+
+h.  Use pselect(2), if available, to wait for input before calling read(2), so
+    a SIGWINCH can interrupt it, since it doesn't interrupt read(2).
+
+i.  Some memory leaks caused by signals interrupting filename completion have
+    been fixed.
+
+j.  Reading EOF twice on a non-empty line causes EOF to be returned, rather
+    than the partial line.  This can cause partial lines to be executed on
+    SIGHUP, for example.
+
+k.  Fixed a bug concerning deleting multibyte characters from the search
+    string while performing an incremental search.
+
+l.  Fixed a bug with tilde expanding directory names in filename completion.
+
+m.  Fixed a bug that did not allow binding sequences beginning with a `\'.
+
+n.  Fixed a redisplay bug involving incorrect line wrapping when the prompt
+    contains a multibyte character in the last screen column.
+
+o.  Fixed a bug that caused history expansion to disregard characters that are
+    documented to delimit a history event specifier without requiring `:'.
+
+p.  Fixed a bug that could cause reading past the end of a string when reading
+    the value when binding the set of isearch terminators.
+
+q.  Fixed a bug that caused readline commands that depend on knowing which
+    key invoked them to misbehave when dispatching key sequences that are
+    prefixes of other key bindings.
+
+r.  Paren matching now works in vi insert mode.
+
+3.  New Features in Bash
+
+a.  There is now a settable configuration #define that will cause the shell
+    to exit if the shell is running setuid without the -p option and setuid
+    to the real uid fails.
+
+b.  Command and process substitutions now turn off the `-v' option when
+    executing, as other shells seem to do.
+
+c.  The default value for the `checkhash' shell option may now be set at
+    compile time with a #define.
+
+d.  The `mapfile' builtin now has a -d option to use an arbitrary character
+    as the record delimiter, and a -t option  to strip the delimiter as
+    supplied with -d.
+
+e.  The maximum number of nested recursive calls to `eval' is now settable in
+    config-top.h; the default is no limit.
+
+f.  The `-p' option to declare and similar builtins will display attributes for
+    named variables even when those variables have not been assigned values
+    (which are technically unset).
+
+g.  The maximum number of nested recursive calls to `source' is now settable
+    in config-top.h; the default is no limit.
+
+h.  All builtin commands recognize the `--help' option and print a usage
+    summary.
+
+i.  Bash does not allow function names containing `/' and `=' to be exported.
+
+j.  The `ulimit' builtin has new -k (kqueues) and -P (pseudoterminals) options.
+
+k.  The shell now allows `time ; othercommand' to time null commands.
+
+l.  There is a new `--enable-function-import' configuration option to allow
+    importing shell functions from the environment; import is enabled by
+    default.
+
+m.  `printf -v var ""' will now set `var' to the empty string, as if `var=""'
+    had been executed.
+
+n.  GLOBIGNORE, the pattern substitution word expansion, and programmable
+    completion match filtering now honor the value of the `nocasematch' option.
+
+o.  There is a new ${parameter@spec} family of operators to transform the
+    value of `parameter'.
+
+p.  Bash no longer attempts to perform compound assignment if a variable on the
+    rhs of an assignment statement argument to `declare' has the form of a
+    compound assignment (e.g., w='(word)' ; declare foo=$w); compound
+    assignments are accepted if the variable was already declared as an array,
+    but with a warning.
+
+q.  The declare builtin no longer displays array variables using the compound
+    assignment syntax with quotes; that will generate warnings when re-used as
+    input, and isn't necessary.
+
+r.  Executing the rhs of && and || will no longer cause the shell to fork if
+    it's not necessary.
+
+s.  The `local' builtin takes a new argument: `-', which will cause it to save
+    the single-letter shell options and restore their previous values at
+    function return.
+
+t.  `complete' and `compgen' have a new `-o nosort' option, which forces
+    readline to not sort the completion matches.
+
+u.  Bash now allows waiting for the most recent process substitution, since it
+    appears as $!.
+
+v.  The `unset' builtin now unsets a scalar variable if it is subscripted with
+    a `0', analogous to the ${var[0]} expansion.
+
+w.  `set -i' is no longer valid, as in other shells.
+
+x.  BASH_SUBSHELL is now updated for process substitution and group commands
+    in pipelines, and is available with the same value when running any exit
+    trap.
+
+y.  Bash now checks $INSIDE_EMACS as well as $EMACS when deciding whether or
+    not bash is being run in a GNU Emacs shell window.
+
+z.  Bash now treats SIGINT received when running a non-builtin command in a
+    loop the way it has traditionally treated running a builtin command:
+    running any trap handler and breaking out of the loop.
+
+aa. New variable: EXECIGNORE; a colon-separate list of patterns that will
+    cause matching filenames to be ignored when searching for commands.
+
+bb. Aliases whose value ends in a shell metacharacter now expand in a way to
+    allow them to be `pasted' to the next token, which can potentially change
+    the meaning of a command (e.g., turning `&' into `&&').
+
+4.  New Features in Readline
+
+a.  The history truncation code now uses the same error recovery mechanism as
+    the history writing code, and restores the old version of the history file
+    on error.  The error recovery mechanism handles symlinked history files.
+
+b.  There is a new bindable variable, `enable-bracketed-paste', which enables
+    support for a terminal's bracketed paste mode.
+
+c.  The editing mode indicators can now be strings and are user-settable
+    (new `emacs-mode-string', `vi-cmd-mode-string' and `vi-ins-mode-string'
+    variables).  Mode strings can contain invisible character sequences.
+    Setting mode strings to null strings restores the defaults.
+
+d.  Prompt expansion adds the mode string to the last line of a multi-line
+    prompt (one with embedded newlines).
+
+e.  There is a new bindable variable, `colored-completion-prefix', which, if
+    set, causes the common prefix of a set of possible completions to be
+    displayed in color.
+
+f.  There is a new bindable command `vi-yank-pop', a vi-mode version of emacs-
+    mode yank-pop.
+
+g.  The redisplay code underwent several efficiency improvements for multibyte
+    locales.
+
+h.  The insert-char function attempts to batch-insert all pending typeahead
+    that maps to self-insert, as long as it is coming from the terminal.
+
+i.  rl_callback_sigcleanup: a new application function that can clean up and
+    unset any state set by readline's callback mode.  Intended to be used
+    after a signal.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.3-release, and
+the previous version, bash-4.3-rc2.
+
+1.  Changes to Bash
+
+a.  Only Posix-mode shells should exit on an assignment failure in the
+    temporary environment preceding a special builtin.  This is how it's been
+    documented.
+
+b.  Fixed a bug that caused a failed special builtin to not exit a posix-mode
+    shell if the failing builtin was on the LHS of a && or ||.
+
+c.  Changed the handling of unquoted backslashes in regular expressions to be
+    closer to bash-4.2.
+
+d.  globstar (**) no longer traverses symbolic links that resolve to
+    directories.  This eliminates some duplicate entries.
+
+e.  Fixed a bug that caused a SIGCHLD trap handler to not be able to change the
+    SIGCHLD disposition.
+
+f.  Fixed a bug that caused a crash when -x was enabled and a command
+    contained a printable multibyte (wide) character.
+
+g.  Fixed a bug that caused an interactive shell without line editing enabled
+    to read invalid data after receiving a SIGINT.
+
+h.  Fixed a bug that caused command word completion to fail if the directory in
+    $PATH where the completion would be found contained single or double quotes.
+
+i.  Fixed a bug that caused a shell with -v enabled to print commands in $()
+    multiple times.
+
+2.  Changes to Readline
+
+a.  Fixed a bug that caused `undo' to reference freed memory or null pointers.
+
+3.  New Features in Bash
+
+a.  The [[ -v ]] option now understands array references (foo[1]) and returns
+    success if the referenced element has a value.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.3-rc2, and the
+previous version, bash-4.3-rc1.

+d. Fixed a bug that caused asynchronous commands to not set $? correctly.
+
+e. Fixed a bug that caused out-of-order execution when executing aliases with
+   embedded newlines containing `.' commands.
+
+f. Fixed a bug that caused error messages generated by expansion errors in
+   `for' commands to have the wrong line number.
+
+g. Fixed a bug that caused the `wait' builtin to not be interruptible in an
+   interactive shell with job control enabled.
+
+h. Fixed a bug that caused SIGINT and SIGQUIT to not be trappable in
+   asynchronous subshell commands.
+
+i. Bash now requires that the value assigned to a nameref variable be a valid
+   shell identifier (variable name or array reference).
+
+j. Converting an existing variable to a nameref variable now turns off the
+   -i/-l/-u/-c attributes.
+
+k. Displaying a nameref variable with `declare -p' now displays the nameref
+   variable and its value rather than following the nameref chain.
+
+l. Fixed a problem with interrupt handling that caused a second and subsequent
+   SIGINT to be ignored by interactive shells.
+
+m. Fixed a bug that caused certain positional parameter and array expansions
+   to mishandle (discard) null positional parameters and array elements.
+
+n. The shell no longer blocks receipt of signals while running trap handlers
+   for those signals, and allows most trap handlers to be run recursively
+   (running trap handlers while a trap handler is executing).
+
+o. The shell now handles backslashes in regular expression arguments to the
+   [[ command's =~ operator slightly differently, resulting in more
+   consistent behavior.
+
+2.  Changes to Readline
+
+a. Fixed a bug that could cause readline to crash and seg fault attempting to
+   expand an empty history entry.
+
+b. Fixed a bug that caused a bad entry in the $LS_COLORS variable to abort all
+   color processing but leave color enabled.
+
+c. Fixed a bug that caused display problems with multi-line prompts containing
+   invisible characters on multiple lines.
+
+d. Fixed a bug that caused effects made by undoing changes to a history line to
+   be discarded.

+3.  New Features in Bash
+
+4.  New Features in Readline
+
+a.  When creating shared libraries on Mac OS X, the pathname written into the
+    library (install_name) no longer includes the minor version number.

+previous version, bash-4.3-beta2.
+
+1.  Changes to Bash
+
+a. Fixed a bug in bash completion that caused a tilde to be expanded even if
+   the `direxpand' option was not enabled.
+
+b. Fixed a potential bug that could cause corrupted input in interactive shells
+   running without line editing and with `ignoreeof' enabled.
+
+c. Fixed a bug that could cause failures when opening pipes back to shells
+   created to run process substitutions.
+
+d. Fixed a bug that caused an assignment to TEXTDOMAIN to require TEXTDOMAINDIR
+   to be set in order to actually change the current text domain.
+
+e. Changed the way redirections are printed to avoid confusion when the target
+   of an output redirection is a process substitution beginning with `>'.
+
+2.  Changes to Readline
+
+a. Shared library building is now supported on Mac OS X 10.9 (Darwin 13).
+
+3.  New Features in Bash
+
+a. `cd' has a new `-@' option to browse a file's extended attributes on
+   systems that support O_XATTR.
+
+4.  New Features in Readline
+
+a. There are additional default key bindings for MinGW32
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.3-beta2, and the
+previous version, bash-4.3-beta.
+
+1.  Changes to Bash
+
+a.  Fixed a bug that caused assignment to an unset variable using a negative
+    subscript to result in a segmentation fault.
+
+b.  Fixed a bug that caused assignment to a string variable using a negative
+    subscript to use the incorrect index.
+
+c.  Fixed a bug that caused some strings to be interpreted as invalid
+    extended globbing expressions when used with the help builtin.
+
+d.  Fixed a bug that caused an attempt to trap a signal whose disposition
+    cannot be changed to reference uninitialized memory.
+
+e.  Command completion now skips assignment statements preceding a command
+    name and completes the command.
+
+f.  Fixed a bug that caused `compgen -f' in a non-interactive shell to dump
+    core under certain circumstances.
+
+g.  Fixed a bug that caused the `read -N' to misbehave when the input stream
+    contains 0xff.
+
+2.  Changes to Readline
+
+a.  Changed message when an incremental search fails to include "failed" in
+    the prompt and display the entire search string instead of just the last
+    matching portion.
+
+b.  Fixed a bug that caused an arrow key typed to an incremental search prompt
+    to process the key sequence incorrectly.
+
+c.  Additional key bindings for arrow keys on MinGW.
+
+3.  New Features in Bash
+
+a.  The help builtin now attempts substring matching (as it did through
+    bash-4.2) if exact string matching fails.
+
+b.  The fc builtin now interprets -0 as the current command line.
+
+c.  Completing directory names containing shell variables now adds a trailing
+    slash if the expanded result is a directory.
+
+4.  New Features in Readline
+
+a.  rl_change_environment: new application-settable variable that controls
+    whether or not Readline modifies the environment (currently readline
+    modifies only LINES and COLUMNS).
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.3-beta, and the
+previous version, bash-4.3-alpha.
+
+1.  Changes to Bash
+
+a.  Fixed a bug in the prompt directory name "trimming" code that caused
+    memory corruption and garbled the results.
+
+b.  Fixed a bug that caused single quotes that resulted from $'...' quoting
+    in the replacement portion of a double-quoted ${word/pat/rep} expansion
+    to be treated as quote characters.
+
+c.  Fixed a bug that caused assignment statements preceding a command word to
+    result in assignment statements following a declaration command to not be
+    expanded like assignment statements.
+
+d.  Fixed a bug with variable search order in the presence of local variables
+    with the same name as variables in the temporary environment supplied to
+    a shell function.
+
+e.  Fixed a bug that caused constructs like 1<(2) to be interpreted as process
+    substitutions even in an arithmetic context.
+
+f.  Fixed several cases where `invisible' variables (variables with attributes
+    but no values, which are technically unset) were treated incorrectly.
+
+g.  Fixed a bug that caused group commands in pipelines that were not the
+    last element to not run the EXIT trap.
+
+h.  Fixed a bug that caused `unset -n' to not unset a nameref variable in
+    certain cases.
+
+i.  Fixed the nameref circular reference checking to be less strict and only
+    disallow a nameref variable with the same value as its name at the global
+    scope.
+
+j.  Fixed a bug that caused trap handlers to be executed recursively,
+    corrupting internal data structures.
+
+k.  Fixed a bug that could result in bash not compiling if certain options were
+    not enabled.
+
+l.  Fixed a bug that caused the arithmetic expansion code to attempt variable
+    assignments when operator precedence prohibited them.
+
+m.  Word expansions like ${foo##bar} now understand indirect variable references.
+
+n.  Fixed a bug that caused `declare -fp name' to not display a function 
+    definition.
+
+o.  Fixed a bug that caused asynchronous child processes to modify the stdin
+    file pointer when bash was using it to read a script, which modified the
+    parent's value as well.
+
+2.  Changes to Readline
+
+a.  Fixed a bug in vi mode that caused the arrow keys to set the saved last
+    vi-mode command to the wrong value.
+

+    waiting for a child process to exit.
+
+g.  Bash doesn't try to run things in a signal handler context when it gets a

+    process substitutions containing comments and quoted strings.
+
+t.  Fixed a problem with the bash malloc's internal idea of the top of the
+    memory heap that resulted in incorrect decisions to try to reduce the
+    break and give memory back to the kernel.
+
+u.  There are changes to the expansions performed on compound array assignments,
+    in an effort to make foo=( [ind1]=bar [ind2]=baz ) identical to
+    foo[ind1]=bar foo[ind2]=baz.
+
+v.  Bash now reports an error if `read -a name' is used when `name' is an

+
+z.  Fixed several bugs with the built-in snprintf replacement and field widths
+    and floating point.
+
+aa. Fixed a bug that caused incorrect offset calculations and input buffer

+
+bb. Fixed several bugs where bash performed arithmetic evaluation in contexts
+    where evaluation is suppressed.
+
+cc. Fixed a bug that caused bash to close FIFOs used for process substitution
+    too early when a shell function was executing, but protect against using
+    all file descriptors when the shell functions are invoked inside loops.
+
+dd. Added checks for printable (and non-printable) multibyte characters for
+    use in error messages.
+
+ee. Fixed a bug that caused ^O (operate-and-get-next) to not work correctly
+    at the end of the history list.
+
+ff. Fixed a bug that caused command-oriented history to incorrectly combine
+    here documents into one line.
+
+gg. Fixed a bug that caused importing SHELLOPTS from the environment into a
+    Posix-mode shell to print an error message and refuse to parse it.
+
+hh. Fixed a bug that caused the shell to delete an extra history entry when
+    using `history -s'.
+
+ii. Fixed a bug that caused floating-point exceptions and overflow errors
+    for the / and % arithmetic operators when using INTMAX_MIN and -1.
+
+jj. Fixed a bug that caused parsing errors when reading an arithmetic for
+    loop inside a command substitution.
+
+kk. Fixed a bug that caused a readonly function to be unset when unset was
+    called without the -f or -v option.
+
+ll. Fixed several bugs in the code that quotes characters special to regular
+    expressions when used in a quoted string on the RHS of the =~ operator
+    to the [[ command.
+
+mm. Fixed a bug that caused redirections to fail because the file descriptor
+    limit was set to a value less than 10.
+
+nn. Fixed a bug that caused the `read' builtin to execute code in a signal
+    handler context if read timed out.
+
+oo. Fixed a bug that caused extended globbing patterns to not match files
+    beginning with `.' correctly when a `.' was explicitly supplied in the
+    pattern.
+
+pp. Fixed a bug that caused key sequences longer than two characters to not
+    work when used with `bind -x'.
+
+qq. Fixed a bug that resulted in redefined functions having the wrong source
+    file names in BASH_SOURCE.
+
+rr. Fixed a bug that caused the read builtin to assign null strings to variables
+    when using `read -N', which caused core dumps when referenced
+
+ss. Fixed a bug that caused `bash -m script' to not enable job control while
+    running the script.
+
+tt. Fixed a bug that caused `printf -v var' to dump core when used with the

+
+uu. Fixed a bug that caused the shell to exit with the wrong status if -e was
+    active and the shell exited on a substitution error.
+
+vv. Fixed a bug that caused the shell to seg fault if an array variable with
+    the same name as an existing associative array was implicitly created by
+    an assignment (declare a[n]=b).
+
+ww. Fixed a bug that caused a redirection to misbehave if the number specified
+    for a file descriptor overflows an intmax_t.
+
+xx. Fixed several bugs with the handling of valid and invalid unicode character
+    values when used with the \u and \U escape sequences to printf and $'...'.
+
+yy. Fixed a bug that caused tildes to not be escaped in expanded filenames,
+    making them subject to later expansion.
+
+zz. When using the pattern substitution word expansion, bash now runs the
+    replacement string through quote removal, since it allows quotes in that
+    string to act as escape characters.  This is not backwards compatible, so
+    it can be disabled by setting the bash compatibility mode to 4.2.
+
+aaa. Fixed the rest of the cases where the shell runs non-allowed code in a
+     signal handler context.
+
+bbb. Fixed a bug that caused spurious DEL characters (\177) to appear in
+     double-quoted expansion where the RHS is evaluated to the empty string.
+
+ccc. Fixed a bug that caused the use of the shell's internal random number
+     generator for temporary file names to perturb the random number
+     sequence.
+
+ddd. Fixed several bugs that caused `declare -g' to not set the right global
+     variables or to misbehave when declaring global indexed arrays.
+
+eee. Fixed a logic bug that caused extended globbing in a multibyte locale to
+     cause failures when using the pattern substititution word expansions.
+
+fff. Fixed a bug that caused the `lastpipe' option to corrupt the file
+     descriptor used to read the script.
+
+ggg. Fixed a bug that causes the shell to delete DEL characters in the
+     expanded value of variables used in the same quoted string as variables
+     that expand to nothing.
+
+hhh. Fixed a bug that caused the shell to assign the wrong value from an
+     assignment like (( x=7 )) when `x' was an existing array variable.
+
+iii. Fixed a bug that caused the shell to misbehave when generating sequences
+     and the boundary values overflow an intmax_t.
+
+jjj. Fixed a bug caused expansion errors if an expansion of "$@" appeared
+     next to another expansion (e.g.. "${@}${x}").
+
+kkk. Fixed a potential buffer overflow bug when performing /dev/fd expansion.
+
+lll. Fixed a bug that resulted in an extra semicolon being added to compound
+     assignments when they were added to the history list.
+
+mmm. Fixed a bug that caused mapfile to read one extra line from the input.
+
+nnn. Fixed a bug that caused the mail checking code to use uninitialized
+     values.
+
+ooo. Fixed a bug that prevented history timestamps from being saved if the
+     history comment character is unset.
+
+ppp. Fixed a bug that caused the case-modifying expansions to not work with
+     multibyte characters.
+
+qqq. Fixed a bug that caused the edit-and-execute bindable readline command
+     to see the wrong data if invoked in the middle of a multi-line quoted
+     string.
+
+rrr. Fixed a bug that resulted in the shell returning the wrong exit status
+     for a background command on systems that recycle PIDs very quickly.
+
+sss. Fixed a bug that caused asynchronous group commands to not run any EXIT
+     trap defined in the body of the command.
+
+ttt. Fixed a bug that caused `eval "... ; return"' to not clean up properly.
+
+uuu. Fixed a bug that caused the shell to dump core if `read' reads an escaped
+     IFS whitespace character.
+
+vvv. Fixed a bug that caused BASH_COMMAND to be set to an incorrect value when
+     executing a (...) subshell.
+
+www. Fixed a couple of pointer aliasing bugs with the token string in arithmetic
+     evaluation.
+
+xxx. Fixed a bug with parsing multi-line command substitutions when reading
+     the `do' keyword followed by whitespace.
+
+yyy. Fixed a bug that caused the shell to seg fault if the time given to the
+     printf %(...)T format overflowed the value accepted by localtime(3).
+
+zzz. Fixed a problem with displaying help topics in two columns when the
+     translated text contained multibyte characters.
+
+aaaa. Fixed a bug with the extended globbing pattern matcher where a `*' was
+      followed by a negated extended glob pattern.
+
+bbbb. Fixed a race condition with short-lived coproc creation and reaping that
+      caused the child process to be reaped before the various coproc shell
+      variables were initialized.
+
+cccc. Fixed a bug where turning off `errexit' in command substitution subshells
+      was not reflected in $SHELLOPTS.
+
+dddd. Partially fixed an inconsistency in how the shell treated shell
+      functions run from an EXIT trap.
+
+eeee. Fixed a bug in how the shell invalidated FIFOs used for process
+      substitution when executing a pipeline (once rather than in every child).
+
+ffff. Fixed a bug that occurred when expanding a special variable ($@, $*)
+      within double quotes and the expansion resulted in an empty string.
+
+gggg. Fixed bugs with executing a SIGCHLD trap handler to make sure that it's
+      executed once per exited child.
+
+hhhh. Fixed a bug that caused `declare' and `test' to find variables that
+      had been given attributes but not assigned values.  Such variables are
+      not set.
+
+iiii. Fixed a bug that caused commands in process substitutions to not look in
+      the local temporary environment when performing word expansions.
+
+jjjj. Fixed several problems with globstar expansions (**/**) returning null
+      filenames and multiple instances of the same pathname.
+
+kkkk. Fixed an oversight that did not allow the exit status of `coproc' to
+      be inverted using `!'.
+
+llll. Fixed a bug that caused the -e option to be re-enabled using `set -e'
+      even when executing in a context where -e is ignored.
+
+mmmm. Fixed a (mostly theoretical) bug with input lines longer than SIZE_MAX.
+
+nnnn. Fixed a bug that could result in double evaluation of command
+      substitutions when they appear in failed redirections.
+
+oooo. Fixed a bug that could cause seg faults during `mapfile' callbacks if
+      the callback unsets the array variable mapfile is using.
+
+pppp. Fixed several problems with variable assignments using ${var:=value}
+      when the variable assignment is supposed to have side effects.
+
+qqqq. Fixed a bug that caused a failure of an assignment statement preceding a
+      builtin caused the next invocation of a special builtin to exit the shell.
+
+rrrr. Fixed several problems with IFS when it appears in the temporary environment
+      and is used in redirections.
+
+ssss. Fixed a problem that caused IFS changes using ${IFS:=value} to modify
+      how preceding expansions were split.
+
+tttt. Fixed a problem that caused subshells to not run an EXIT trap they set.
+
+uuuu. Fixed a problem that caused shells started in posix mode to attempt to
+      import shell functions with invalid names from the environment.  We now
+      print a warning.
+
+vvvv. Worked around a kernel problem that caused SIGCHLD to interrupt open(2)
+      on a FIFO used for process substitution, even if the SIGCHLD handler was
+      installed with the SA_RESTART flag.
+
+wwww. Fixed a problem that resulted in inconsistent expansion of $* and ${a[*]}.
+
+xxxx. Fixed a problem that caused `read -t' to crash when interrupted by
+      SIGINT.
+
+yyyy. Fixed a problem that caused pattern removal to fail randomly because the
+      pattern matcher read beyond the end of a string.
+
+zzzz. Fixed a bug that caused core dumps when shell functions tried to create
+      local shadow copies of special variables like GROUPS.
+
+aaaaa. Fixed a bug that caused SIGTERM to be occasionally lost by children of
+       interactive shells when it arrived before the child process reset the
+       handler from SIG_DFL.
+
+bbbbb. Fixed a bug that caused redirections like <&n- to leave file descriptor
+       n closed if executed with a builtin command.
+
+ccccc. Fixed a bug that caused incorrect completion quoting when completing a
+       word containing a globbing character with `show-all-if-ambiguous' set.
+
+ddddd. Fixed a bug that caused printf's %q format specifier not to quote a
+       tilde even if it appeared in a location where it would be subject to
+       tilde expansion.
+
+2.  Changes to Readline
+
+a.  Fixed a bug that did not allow the `dd', `cc', or `yy' vi editing mode
+    commands to work on the entire line.
+
+b.  Fixed a bug that caused redisplay problems with prompts longer than 128
+    characters and history searches.
+
+c.  Fixed a bug that caused readline to try and run code to modify its idea
+    of the screen size in a signal handler context upon receiving a SIGWINCH.
+
+d.  Fixed a bug that caused the `meta' key to be enabled beyond the duration
+    of an individual call top readline().
+    
+e.  Added a workaround for a wcwidth bug in Mac OS X that caused readline's
+    redisplay to mishandle zero-width combining characters.
+
+f.  Fixed a bug that caused readline to `forget' part of a key sequence when
+    a multiple-key sequence caused it to break out of an incremental search.
+
+g.  Fixed bugs that caused readline to execute code in a signal handler
+    context if interrupted while reading from the file system during completion.
+
+h.  Fixed a bug that caused readline to `forget' part of a key sequence when
+    reading an unbound multi-character key sequence.
+
+i.  Fixed a bug that caused Readline's signal handlers to be installed beyond
+    the bounds of a single call to readline().
+
+j.  Fixed a bug that caused the `.' command to not redo the most recent `R'
+    command in vi mode.
+
+k.  Fixed a bug that caused ignoring case in completion matches to result in
+    readline using the wrong match.
+
+l.  Paren matching now works in vi insert mode.
+
+m.  Fix menu-completion to make show-all-if-ambiguous and menu-complete-display-prefix
+    work together.
+
+n.  Fixed a bug that didn't allow the `cc', `dd', or `yy' commands to be redone
+    in vi editing mode.
+
+o.  Fixed a bug that caused the filename comparison code to not compare
+    multibyte characters correctly when using case-sensitive or case-mapping
+    comparisons.
+
+p.  Fixed the input reading loop to call the input hook function only when there
+    is no terminal input available.
+
+q.  Fixed a bug that caused binding a macro to a multi-character key sequence
+    where the sequence and macro value share a common prefix to not perform
+    the macro replacement.
+
+r.  Fixed several redisplay errors with multibyte characters and prompts
+    containing invisible characters when using horizontal scrolling.
+
+s.  Fixed a bug that caused redisplay errors when trying to overwrite
+    existing characters using multibyte characters.
+
+3.  New Features in Bash
+
+a.  The `helptopic' completion action now maps to all the help topics, not just
+    the shell builtins.
+
+b.  The `help' builtin no longer does prefix substring matching, so `help read'
+    does not match `readonly'.
+
+c.  The shell can be compiled to not display a message about processes that
+    terminate due to SIGTERM.
+
+d.  Non-interactive shells now react to the setting of checkwinsize and set
+    LINES and COLUMNS after a foreground job exits.
+
+e.  There is a new shell option, `globasciiranges', which, when set to on,
+    forces globbing range comparisons to use character ordering as if they
+    were run in the C locale.
+
+f.  There is a new shell option, `direxpand', which makes filename completion
+    expand variables in directory names in the way bash-4.1 did.
+
+g.  In Posix mode, the `command' builtin does not change whether or not a
+    builtin it shadows is treated as an assignment builtin.
+
+h.  The `return' and `exit' builtins accept negative exit status arguments.
+
+i.  The word completion code checks whether or not a filename containing a
+    shell variable expands to a directory name and appends `/' to the word
+    as appropriate.  The same code expands shell variables in command names
+    when performing command completion.
+
+j.  In Posix mode, it is now an error to attempt to define a shell function
+    with the same name as a Posix special builtin.
+
+k.  When compiled for strict Posix conformance, history expansion is disabled
+    by default.
+
+l.  The history expansion character (!) does not cause history expansion when
+    followed by the closing quote in a double-quoted string.
+
+m.  `complete' and its siblings compgen/compopt now takes a new `-o noquote'
+    option to inhibit quoting of the completions.
+
+n.  Setting HISTSIZE to a value less than zero causes the history list to be
+    unlimited (setting it 0 zero disables the history list).
+
+o.  Setting HISTFILESIZE to a value less than zero causes the history file size
+    to be unlimited (setting it to 0 causes the history file to be truncated
+    to zero size).
+
+p.  The `read' builtin now skips NUL bytes in the input.
+
+q.  There is a new `bind -X' option to print all key sequences bound to Unix
+    commands.
+
+r.  When in Posix mode, `read' is interruptible by a trapped signal.  After
+    running the trap handler, read returns 128+signal and throws away any
+    partially-read input.
+
+s.  The command completion code skips whitespace and assignment statements
+    before looking for the command name word to be completed.
+
+t.  The build process has a new mechanism for constructing separate help files
+    that better reflects the current set of compilation options.
+
+u.  The -nt and -ot options to test now work with files with nanosecond
+    timestamp resolution.
+
+v.  The shell saves the command history in any shell for which history is
+    enabled and HISTFILE is set, not just interactive shells.
+
+w.  The shell has `nameref' variables and new -n(/+n) options to declare and
+    unset to use them, and a `test -R' option to test for them.
+
+x.  The shell now allows assigning, referencing, and unsetting elements of
+    indexed arrays using negative subscripts (a[-1]=2, echo ${a[-1]}) which
+    count back from the last element of the array.
+
+y.  The {x}<word redirection feature now allows words like {array[ind]} and
+    can use variables with special meanings to the shell (e.g., BASH_XTRACEFD).
+
+z.  There is a new CHILD_MAX special shell variable; its value controls the
+    number of exited child statuses the shell remembers.
+
+aa. There is a new configuration option (--enable-direxpand-default) that
+    causes the `direxpand' shell option to be enabled by default.
+
+bb. Bash does not do anything special to ensure that the file descriptor
+    assigned to X in {x}<foo remains open after the block containing it
+    completes.
+
+cc. The `wait' builtin has a new `-n' option to wait for the next child to
+    change status.
+
+dd. The `printf' %(...)T format specifier now uses the current time if no
+    argument is supplied.
+
+ee. There is a new variable, BASH_COMPAT, that controls the current shell
+    compatibility level.
+
+ff. The `popd' builtin now treats additional arguments as errors.
+
+gg. The brace expansion code now treats a failed sequence expansion as a
+    simple string and will continue to expand brace terms in the remainder
+    of the word.
+
+4.  New Features in Readline
+
+a.  Readline is now more responsive to SIGHUP and other fatal signals when
+    reading input from the terminal or performing word completion but no
+    longer attempts to run any not-allowable functions from a signal handler
+    context.
+
+b.  There are new bindable commands to search the history for the string of
+    characters between the beginning of the line and the point
+    (history-substring-search-forward, history-substring-search-backward)
+
+c.  Readline allows quoted strings as the values of variables when setting
+    them with `set'.  As a side effect, trailing spaces and tabs are ignored
+    when setting a string variable's value.
+
+d.  The history library creates a backup of the history file when writing it
+    and restores the backup on a write error.
+
+e.  New application-settable variable: rl_filename_stat_hook: a function called
+    with a filename before using it in a call to stat(2).  Bash uses it to
+    expand shell variables so things like $HOME/Downloads have a slash
+    appended.
+
+f.  New bindable function `print-last-kbd-macro', prints the most-recently-
+    defined keyboard macro in a reusable format.
+
+g.  New user-settable variable `colored-stats', enables use of colored text
+    to denote file types when displaying possible completions (colored analog
+    of visible-stats).
+
+h.  New user-settable variable `keyseq-timout', acts as an inter-character
+    timeout when reading input or incremental search strings.
+
+i.  New application-callable function: rl_clear_history. Clears the history list
+    and frees all readline-associated private data.
+
+j.  New user-settable variable, show-mode-in-prompt, adds a characters to the
+    beginning of the prompt indicating the current editing mode.
+
+k.  New application-settable variable: rl_input_available_hook; function to be
+    called when readline needs to check whether there is data available on its
+    input source.  The default hook checks rl_instream.
+
+l.  Readline calls an application-set event hook (rl_signal_event_hook) after
+    it gets a signal while reading input (read returns -1/EINTR but readline
+    does not handle the signal immediately) to allow the application to handle
+    or otherwise note it.  Not currently called for SIGHUP or SIGTERM.
+
+m.  If the user-settable variable `history-size' is set to a value less than
+    0, the history list size is unlimited.

+and the previous version, bash-4.2-rc1.
+
+1.  Changes to Bash
+
+a.  Changes to bash_directory_completion_hook so that it's assigned to the
+    readline rl_directory_rewrite_hook variable, which modifies the directory
+    name passed to opendir without modifying the directory name the user
+    typed.
+
+b.  Fixed bug in select builtin that caused it to not terminate correctly if
+    the read timed out due to $TMOUT.
+
+c.  Fixed a problem that resulted in non-repeatable sequences of random
+    numbers when RANDOM=0.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.2-rc1,
+and the previous version, bash-4.2-beta.
+
+1.  Changes to Bash
+
+a.  Fixed a bug that caused some redirection errors to leak file descriptors.
+
+b.  Fixed a bug that caused unary `+' and `-' arithmetic operators to have a
+    higher precedence than unary `!' and `~'.
+
+c.  Fixed a bug that caused simple commands in a pipeline to affect the exit
+    status ($?) seen by subsequent pipeline commands.
+
+d.  A number of cygwin-specific changes to avoid the use of text-mode files
+    and file access, and to make sure that \r is handled correctly.
+
+e.  Fixed a bug that caused the read builtin to not return failure if an
+    attempt is made to assign to a readonly variable.
+
+f.  Fixed a bug that caused some builtin usage messages to not be translated.
+
+g.  Fixed a bug that caused the getopts builtin to not return failure if an
+    attempt is made to assign to a readonly variable.  Now it returns 2.
+
+h.  Fixed the cd and pwd builtins to return failure if PWD is readonly and
+    cannot be assigned to.
+
+i.  Added code to check the return value of access(2) on Solaris systems,
+    since it returns success for executable tests (e.g., `test -x') when
+    run by root, even if the file permissions don't allow execution.
+
+2.  Changes to Readline
+
+a.  Fixed a bug that caused directory names in words to be completed to not
+    be dequoted correctly.
+
+3.  New Features in Bash
+
+4.  New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.2-beta,
+and the previous version, bash-4.2-alpha.
+
+1.  Changes to Bash
+
+a.  Fixed a bug that caused the \W prompt string escape to not add a closing
+    NULL.
+
+b.  Fixed a bug that caused partially-quoted words that were not subject to
+    word splitting to retained quoted NULLs.
+
+c.  Added considerable efficiency speedups when pattern matching in multibyte
+    locales by skipping multibyte character functions where possible.
+
+d.  Added considerable speedups to variable expansion when in multibyte locales.
+
+e.  Fixed a bug that caused the expansion of $* when there are no positional
+    parameters to cause the shell to dump core when used in a pattern
+    matching context.
+
+f.  Fixed a bug that caused variable expansions preceding regular builtins to
+    not change the shell environment during their execution.
+
+2.  Changes to Readline
+
+a.  Fixed a bug that made an explicit argument of 0 to yank-last-arg behave
+    as if it were a negative argument.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.2-alpha,
+and the previous version, bash-4.1-release.
+
+1.  Changes to Bash
+
+a.  Fixed a bug in the parser when processing alias expansions containing
+    quoted newlines.
+
+b.  Fixed a memory leak in associative array expansion.
+
+c.  Fixed a bug that caused quoted here-strings to be requoted when printed.
+
+d.  Fixed a bug in arithmetic expansion that caused the index in an array
+    expansion to be evaluated twice under certain circumstances.
+
+e.  Fixed several bugs with the expansion and display of variables that have
+    been given attributes but not values and are technically unset.
+
+f.  Fixed a bug that caused core dumps when using filename completion that
+    expands to a filename containing a globbing character.
+
+g.  Fixed a bug that caused assignment statements preceding a special builtin
+    when running in Posix mode to not persist after the builtin completed
+    when the special builtin was executed in a shell function without any
+    local variables.
+
+h.  Fixed a bug that caused a command to remain in the hash table even after
+    `hash command' did not find anything if there was already an existing
+    hashed pathname.
+
+i.  Fixed several bugs caused by executing unsafe functions from a signal
+    handler in the cases where a signal handler is executed immediately
+    rather than setting a flag for later execution.
+
+j.  Fixed a bug that caused some internal flag variables to be set
+    incorrectly if `read -t' timed out.
+
+k.  Fixed a Posix compatibility issue by making sure that a backslash escaping
+    a `}' within a double-quoted ${...} parameter expansion is removed as part
+    of the parameter expansion.
+
+l.  Fixed a bug that caused execution of a trap to overwrite PIPESTATUS.
+
+m.  Fixed a bug that caused here documents to not be displayed correctly
+    when attached to commands inside compound commands.
+
+n.  Fixed a bug that caused the printf builtin to use the wrong precision
+    when using the `*' modifier.
+
+o.  Fixed a bug that caused an arriving SIGCHLD to interrupt output functions
+    like those invoked by echo or printf.
+
+p.  Changed to use a more robust mechanism than eaccess(2) when test is
+    checking filenames for execution permission.
+
+q.  Fixed a bug that caused spurious semicolons to be added into the command
+    history in certain cases.
+
+r.  Fixed a bug that caused the shell to free non-allocated memory when
+    unsetting element 0 of an associative array after it was assigned
+    implicitly.
+
+s.  Fixed a bug that could cause the shell to dump core if using the `v'
+    vi editing command on a multi-line command.
+
+t.  Fixed a bug that left FIFOs opened by process substitutions open long
+    enough to potentially cause file descriptor exhaustion when running a
+    shell function or shell builtin.
+
+u.  Fixed a bug that caused the history expansion functions to not recognize
+    process substitution or extended glob patterns as single words.
+
+v.  Fixed a bug that caused restricted shells to set a restricted command's
+    exit status incorrectly.
+
+w.  Fixed a bug that caused bash to ignore the wrong set of filenames when
+    completing a command using the `complete-filename' readline command.
+
+x.  Fixed a bug that caused a -PID argument following a -s sig or -n sig to
+    not be interpreted as a signal specification.
+
+y.  Changed posix-mode behavior of a parse error in a `.' script or `eval'
+    command to exit the shell under Posix-specified conditions.  Previous
+    versions printed a warning.
+
+z.  Fixed a bug in \W prompt expansion that resulted in incorrect expansion
+    in the event of overlapping strings.
+
+aa. Fixed a bug that caused the := parameter expansion operator to return the
+    wrong value as the result of the expansion.
+
+bb. When in Posix mode, a single quote is not treated specially in a
+    double-quoted ${...} expansion, unless the expansion operator is
+    # or % or the non-Posix `//', `^', and `,'.  In particular, it does
+    not define a new quoting context.  This is from Posix interpretation 221.
+
+cc. Fixed a bug that inadvertently allowed program names containing slashes
+    to be entered into the command hash table.
+
+dd. Fixed a bug that caused the select builtin to incorrectly compute the
+    display width of the arguments in the presence of multibyte characters.
+
+ee. Fixed a bug that caused bash to not change the xtrace file descriptor if
+    BASH_XTRACEFD was found in the shell environment at startup.
+
+ff. Fixed a memory leak in the pattern removal parameter expansion.
+
+gg. Fixed a bug that caused SIGINT to fail to interrupt a nested loop if the
+    loop was in a pipeline.
+
+hh. Fixed a problem in $(...) parsing that caused the parser to add an extra
+    space to a here-document delimiter if the first word contained a `/'.
+
+ii. Fixed a bug that caused functions defined with the `function' reserved
+    word to require braces around the function body.
+
+jj. Fixed a bug that caused bash to dump core when a variable expansion being
+    used as an array subscript failed.
+
+kk. Fixed a bug that caused bash to dump core if the case-modification
+    expansions were used on a variable with a null value.
+
+ll. Fixed a bug that caused partially-quoted strings to be split incorrectly
+    if a variable with a null value was expanded within double quotes.
+
+mm. The pattern substitution word expansion has been sped up dramatically
+    when running in a locale with multibyte characters.
+
+nn. Fixed a bug that caused history -a to not write the correct lines to
+    the history file if all the new lines in the history list were added
+    since the last time the history file was read or written.
+
+oo. Fixed a bug that caused completion of a word with an unclosed `` command
+    substitution to set the prompt incorrectly.
+
+pp. Fixed a bug that caused extended globbing patterns in $HISTIGNORE or
+    $GLOBIGNORE to be incorrectly scanned.
+
+qq. Fixed a bug caused by closing file descriptors 3-20 on shell startup.  The
+    shell now sets them to close-on-exec.
+
+rr. Fixed a bug that caused the exit status of `exec file' to be set incorrectly
+    if `file' was a directory.
+
+ss. Fixed a bug in the `.' builtin to make a non-interactive posix-mode shell
+    exit if the file argument to `.' is not found.  Prefixing exec with 
+    `command' makes the shell not exit. Posix requires this behavior.
+
+tt. Fixed a bug that caused `sh -c 'command exec; exit 1' to hang.
+
+uu. Fixed a bug in $(...) command substitution parsing that caused the shell
+    to treat backslash-newline incorrectly when parsing a comment.
+
+vv. Fixed bug that caused brace expansion sequence generation to misbehave
+    when supplied integers greater than 2**31 - 1.
+
+ww. Fixed a bug that caused failure to save file descriptors for redirections
+    to corrupt shell file descriptors.
+
+xx. Fixed a bug that caused bash-forward-shellword to not correctly handle
+    quoted strings.
+
+2.  Changes to Readline
+
+a.  Fixed a bug that caused the unconverted filename to be added to the list of
+    completions when the application specified filename conversion functions.
+
+b.  Fixed a bug that caused the wrong filename to be passed to opendir when the
+    application has specified a filename dequoting function.
+
+c.  Fixed a bug when repeating a character search in vi mode in the case where
+    there was no search to repeat.
+
+d.  When show-all-if-ambiguous is set, the completion routines no longer insert
+    a common match prefix that is shorter than the text being completed.
+
+e.  The full set of vi editing commands may now be used in callback mode.
+
+f.  Fixed a bug that caused readline to not update its idea of the terminal
+    dimensions while running in `no-echo' mode.
+
+h.  Fixed a bug that caused readline to dump core if an application called
+    rl_prep_terminal without setting rl_instream.
+
+i.  Fixed a bug that caused meta-prefixed characters bound to incremental
+    search forward or backward to not be recognized if they were typed
+    subsequently.
+
+j.  The incremental search code treats key sequences that map to the same
+    functions as (default) ^G, ^W, and ^Y as equivalent to those characters.
+
+k.  Fixed a bug in menu-complete that caused it to misbehave with large
+    negative argument.
+
+l.  Fixed a bug that caused vi-mode yank-last-arg to ring the bell when invoked
+    at the end of the line.
+
+3.  New Features in Bash
+
+a.  `exec -a foo' now sets $0 to `foo' in an executable shell script without a
+    leading #!.
+
+b.  Subshells begun to execute command substitutions or run shell functions or
+    builtins in subshells do not reset trap strings until a new trap is
+    specified.  This allows $(trap) to display the caller's traps and the
+    trap strings to persist until a new trap is set.
+
+c.  `trap -p' will now show signals ignored at shell startup, though their
+    disposition still cannot be modified.
+
+d.  $'...', echo, and printf understand \uXXXX and \UXXXXXXXX escape sequences.
+
+e.  declare/typeset has a new `-g' option, which creates variables in the
+    global scope even when run in a shell function.
+
+f.  test/[/[[ have a new -v variable unary operator, which returns success if
+    `variable' has been set.
+
+g.  Posix parsing changes to allow `! time command' and multiple consecutive
+    instances of `!' (which toggle) and `time' (which have no cumulative
+    effect).
+
+h.  Posix change to allow `time' as a command by itself to print the elapsed
+    user, system, and real times for the shell and its children.
+
+j.  $((...)) is always parsed as an arithmetic expansion first, instead of as
+    a potential nested command substitution, as Posix requires.
+
+k.  A new FUNCNEST variable to allow the user to control the maximum shell
+    function nesting (recursive execution) level.
+
+l.  The mapfile builtin now supplies a third argument to the callback command:
+    the line about to be assigned to the supplied array index.
+
+m.  The printf builtin has a new %(fmt)T specifier, which allows time values
+    to use strftime-like formatting.
+
+n.  There is a new `compat41' shell option.
+
+o.  The cd builtin has a new Posix-mandated `-e' option.
+
+p.  Negative subscripts to indexed arrays, previously errors, now are treated
+    as offsets from the maximum assigned index + 1.
+
+q.  Negative length specifications in the ${var:offset:length} expansion,
+    previously errors, are now treated as offsets from the end of the variable.
+
+r.  Parsing change to allow `time -p --'.
+
+s.  Posix-mode parsing change to not recognize `time' as a keyword if the
+    following token begins with a `-'.  This means no more Posix-mode
+    `time -p'.  Posix interpretation 267.
+
+t.  There is a new `lastpipe' shell option that runs the last command of a
+    pipeline in the current shell context.  The lastpipe option has no
+    effect if job control is enabled.
+
+u.  History expansion no longer expands the `$!' variable expansion.
+
+v.  Posix mode shells no longer exit if a variable assignment error occurs
+    with an assignment preceding a command that is not a special builtin.
+
+w.  Non-interactive mode shells exit if -u is enabled and an attempt is made
+    to use an unset variable with the % or # expansions, the `//', `^', or
+    `,' expansions, or the parameter length expansion.
+
+x.  Posix-mode shells use the argument passed to `.' as-is if a $PATH search
+    fails, effectively searching the current directory.  Posix-2008 change.
+
+4.  New Features in Readline
+
+a.  The history library does not try to write the history filename in the
+    current directory if $HOME is unset.  This closes a potential security
+    problem if the application does not specify a history filename.
+
+b.  New bindable variable `completion-display-width' to set the number of
+    columns used when displaying completions.
+
+c.  New bindable variable `completion-case-map' to cause case-insensitive
+    completion to treat `-' and `_' as identical.
+
+d.  There are new bindable vi-mode command names to avoid readline's case-
+    insensitive matching not allowing them to be bound separately.
+
+e.  New bindable variable `menu-complete-display-prefix' causes the menu
+    completion code to display the common prefix of the possible completions
+    before cycling through the list, instead of after.
+

+b.  Fixed a bug that caused the shell to incorrectly split case patterns if
+    they contained characters in $IFS.
+
+c.  Fixed a bug that caused the shell to set $? to the wrong value when using
+    a construct ending with a variable assignment with set -x enabled and PS4
+    containing a command substitution.
+

+
+e.  Fixed a bug that caused the shell to set $? incorrectly if a parse error
+    occurred in an evaluation context ("eval", trap command, dot script, etc.)
+

+
+i.  Fixed a bug that caused bash to incorrectly report the presence of new

+
+j.  Fixed a bug that caused the shell to not recognize a here-document ending

+
+k.  Fixed a bug that caused the shell to crash when a a dynamic array variable
+    was assigned a scalar value.
+
+2.  Changes to Readline
+
+3.  New Features in Bash

+    callbacks in the history list.
+
+b.  There is a new `compat40' shopt option.

+    only if the compatibility level is greater than 40 (set to 41 by default).
+
+4.  New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.1-alpha,
+and the previous version, bash-4.0-release.
+
+1.  Changes to Bash
+
+a.  Fixed bugs in the parser involving new parsing of the commands contained

+
+b.  Fixed a bug that caused the shell to dump core when performing programmable
+    completion using a shell function.
+
+c.  Fixed a bug in `mapfile' that caused it to invoke callbacks at the wrong
+    time.

+
+e.  Fixed several bugs encountered when reading subscripts in associative
+    array assignments and expansions.
+
+f.  Fixed a bug that under some circumstances caused an associative array to
+    be converted to an indexed array.
+
+g.  Fixed a bug that caused syntax errors and SIGINT interrupts to not set
+    $? to a value > 128.
+
+h.  Fixed a bug that caused the shell to remove FIFOs associated with process
+    substitution inside shell functions.
+
+i.  Fixed a bug that caused terminal attributes to not be reset when the
+    `read' builtin timed out.
+
+j.  Fixed a bug in brace expansion that caused unwanted zero padding of the
+    expanded terms.
+
+k.  Fixed a bug that prevented the |& construct from working as intended when
+    used with a simple command with additional redirections.
+
+l.  Fixed a bug with the case statement ;& terminator that caused the shell to
+    dereference a NULL pointer.
+
+m.  Fixed a bug that caused assignment statements or redirections preceding
+    a simple command name to inhibit alias expansion.
+
+n.  Fixed the behavior of `set -u' to conform to the latest Posix interpretation:
+    every expansion of an unset variable except $@ and $* will cause the
+    shell to exit.
+
+o.  Fixed a bug that caused double-quoted expansions of $* inside word
+    expansions like ${x#$*} to not expand properly when $IFS is empty.
+
+p.  Fixed a bug that caused traps to set $LINENO to the wrong value when they
+    execute.
+
+q.  Fixed a bug that caused off-by-one errors when computing history lines in
+    the `fc' builtin.
+
+r.  Fixed a bug that caused some terminating signals to not exit the shell
+    quickly enough, forcing the kernel to send the signal (e.g., SIGSEGV)
+    multiple times.
+
+s.  Fixed a bug that caused the shell to attempt to add empty lines to the
+    history list when reading here documents.
+
+t.  Made some internal changes that dramatically speeds up sequential indexed
+    array access.
+
+u.  Fixed a bug that caused the shell to write past the end of a string when
+    completing a double-quoted string ending in a backslash.
+
+v.  Fixed a bug that caused the shell to replace too many characters when a
+    pattern match was null in a ${foo//bar} expansion.
+
+w.  Fixed bugs in the expansion of ** that caused duplicate directory names
+    and the contents of the current directory to be omitted.
+
+x.  Fixed a bug that caused $? to not be set correctly when referencing an
+    unset variable with set -u and set -e enabled.
+
+y.  Fixed a bug caused by executing an external program from the DEBUG trap
+    while a pipeline was running.  The effect was to disturb the pipeline
+    state, occasionally causing it to hang.
+
+z.  Fixed a bug that caused the ** glob expansion to dump core if it
+    encountered an unsearchable directory.
+
+aa. Fixed a bug that caused `command -v' and `command -V' to not honor the
+    path set by the -p option.
+
+bb. Fixed a bug that caused brace expansion to take place too soon in some
+    compound array assignments.
+
+cc. Fixed a bug that caused programmable completion functions' changes to
+    READLINE_POINT to not be reflected back to readline.
+
+dd. Fixed a bug that caused the shell to dump core if a trap was executed
+    during a shell assignment statement.
+
+ee. Fixed an off-by-one error when computing the number of positional
+    parameters for the ${@:0:n} expansion.
+
+ff. Fixed a problem with setting COMP_CWORD for programmable completion
+    functions that could leave it set to -1.
+
+gg. Fixed a bug that caused the ERR trap to be triggered in some cases where
+    `set -e' would not have caused the shell to exit.
+
+hh. Fixed a bug that caused changes made by `compopt' to not persist past the
+    completion function in which compopt was executed.
+
+ii. Fixed a bug that caused the list of hostname completions to not be cleared
+    when HOSTNAME was unset.
+
+jj. Fixed a bug that caused variable expansion in here documents to look in
+    any temporary environment.
+
+kk. Bash and readline can now convert file names between precomposed and
+    decomposed Unicode on Mac OS X ("keyboard" and file system forms,
+    respectively).  This affects filename completion (using new
+    rl_filename_rewrite_hook), globbing, and readline redisplay.
+
+ll. The ERR and EXIT traps now see a non-zero value for $? when a parser
+    error after set -e has been enabled causes the shell to exit.
+
+mm. Fixed a bug that in brace expansion that caused zero-prefixed terms to
+    not contain the correct number of digits.
+
+nn. Fixed a bug that caused the shell to free non-allocated memory when
+    unsetting an associative array which had had a value implicitly assigned
+    to index "0".
+
+oo. Fixed a memory leak in the ${!prefix@} expansion.
+
+pp. Fixed a bug that caused printf to not correctly report all write errors.
+
+qq. Fixed a bug that caused single and double quotes to act as delimiters
+    when splitting a command line into words for programmable completion.
+
+rr. Fixed a bug that caused ** globbing that caused **/path/* to match every
+    directory, not just those matching `path'.
+
+ss. Fixed a bug that caused the shell to dump core when running `help' without
+    arguments if the terminal width was fewer than 7 characters.
+
+2.  Changes to Readline
+
+a.  The SIGWINCH signal handler now avoids calling the redisplay code if
+    one arrives while in the middle of redisplay.
+
+b.  Changes to the timeout code to make sure that timeout values greater
+    than one second are handled better.
+
+c.  Fixed a bug in the redisplay code that was triggered by a prompt
+    containing invisible characters exactly the width of the screen.
+
+d.  Fixed a bug in the redisplay code encountered when running in horizontal
+    scroll mode.
+
+e.  Fixed a bug that prevented menu completion from properly completing
+    filenames.
+
+f.  Fixed a redisplay bug caused by a multibyte character causing a line to
+    wrap.
+
+g.  Fixed a bug that caused key sequences of two characters to not be
+    recognized when a longer sequence identical in the first two characters
+    was bound.
+
+h.  Fixed a bug that caused history expansion to be attempted on $'...'
+    single-quoted strings.
+
+i.  Fixed a bug that caused incorrect redisplay when the prompt contained
+    multibyte characters in an `invisible' sequence bracketed by \[ and
+    \].
+
+j.  Fixed a bug that caused history expansion to short-circuit after
+    encountering a multibyte character.
+
+3.  New Features in Bash
+
+a.  Here-documents within $(...) command substitutions may once more be
+    delimited by the closing right paren, instead of requiring a newline.
+
+b.  Bash's file status checks (executable, readable, etc.) now take file
+    system ACLs into account on file systems that support them.
+
+c.  Bash now passes environment variables with names that are not valid
+    shell variable names through into the environment passed to child
+    processes.
+
+d.  The `execute-unix-command' readline function now attempts to clear and
+    reuse the current line rather than move to a new one after the command
+    executes.
+
+e.  `printf -v' can now assign values to array indices.
+
+f.  New `complete -E' and `compopt -E' options that work on the "empty"
+    completion: completion attempted on an empty command line.
+
+g.  New complete/compgen/compopt -D option to define a `default' completion:
+    a completion to be invoked on command for which no completion has been
+    defined.  If this function returns 124, programmable completion is
+    attempted again, allowing a user to dynamically build a set of completions
+    as completion is attempted by having the default completion function
+    install individual completion functions each time it is invoked.
+
+h.  When displaying associative arrays, subscripts are now quoted.
+
+i.  Changes to dabbrev-expand to make it more `emacs-like': no space appended
+    after matches, completions are not sorted, and most recent history entries
+    are presented first.
+
+j.  The [[ and (( commands are now subject to the setting of `set -e' and the
+    ERR trap.
+
+k.  The source/. builtin now removes NUL bytes from the file before attempting
+    to parse commands.
+
+l.  There is a new configuration option (in config-top.h) that forces bash to
+    forward all history entries to syslog.
+
+m.  A new variable $BASHOPTS to export shell options settable using `shopt' to
+    child processes.
+
+n.  There is a new configure option that forces the extglob option to be
+    enabled by default.
+
+o.  New variable $BASH_XTRACEFD; when set to an integer bash will write xtrace
+    output to that file descriptor.
+
+p.  If the optional left-hand-side of a redirection is of the form {var}, the
+    shell assigns the file descriptor used to $var or uses $var as the file
+    descriptor to move or close, depending on the redirection operator.
+
+q.  The < and > operators to the [[ conditional command now do string
+    comparison according to the current locale.
+
+r.  Programmable completion now uses the completion for `b' instead of `a'
+    when completion is attempted on a line like: a $(b c.
+
+s.  Force extglob on temporarily when parsing the pattern argument to
+    the == and != operators to the [[ command, for compatibility.
+
+t.  Changed the behavior of interrupting the wait builtin when a SIGCHLD is
+    received and a trap on SIGCHLD is set to be Posix-mode only.
+
+u.  The read builtin has a new `-N nchars' option, which reads exactly NCHARS
+    characters, ignoring delimiters like newline.
+
+4.  New Features in Readline
+
+a.  New bindable function: menu-complete-backward.
+
+b.  In the vi insertion keymap, C-n is now bound to menu-complete by default,
+    and C-p to menu-complete-backward.
+
+c.  When in vi command mode, repeatedly hitting ESC now does nothing, even
+    when ESC introduces a bound key sequence.  This is closer to how
+    historical vi behaves.
+
+d.  New bindable function: skip-csi-sequence.  Can be used as a default to
+    consume key sequences generated by keys like Home and End without having
+    to bind all keys.
+
+e.  New application-settable function: rl_filename_rewrite_hook.  Can be used
+    to rewrite or modify filenames read from the file system before they are
+    compared to the word to be completed.
+
+f.  New bindable variable: skip-completed-text, active when completing in the
+    middle of a word.  If enabled, it means that characters in the completion
+    that match characters in the remainder of the word are "skipped" rather
+    than inserted into the line.
+
+g.  The pre-readline-6.0 version of menu completion is available as
+    "old-menu-complete" for users who do not like the readline-6.0 version.
+
+h.  New bindable variable: echo-control-characters.  If enabled, and the
+    tty ECHOCTL bit is set, controls the echoing of characters corresponding
+    to keyboard-generated signals.
+
+i.  New bindable variable: enable-meta-key.  Controls whether or not readline
+    sends the smm/rmm sequences if the terminal indicates it has a meta key
+    that enables eight-bit characters.
