+
+[bash-5.1 released]
+
+				   12/7
+				   ----
+Makefile.in
+	- bashline.o: add dependency on ${DEFDIR}/builtext.h. Report from
+	  Fazal Majid <fazal@majid.org>
+
+				   12/11
+				   -----
+builtins/wait.def
+	- wait_builtin: don't assign the variable given with -p if there are no
+	  jobs to wait for. Report and fix from OÄuz <oguzismailuysal@gmail.com>
+
+arrayfunc.c
+	- kvpair_assignment_p: return non-zero if argument L appears to be a
+	  key-value pair associative array compound assignment
+	- expand_and_quote_kvpair_word: run a single word in a key-value pair
+	  associative array compound assignment through the appropriate
+	  expansions and single-quote the result
+
+arrayfunc.h
+	- kvpair_assignment_p, expand_and_quote_kvpair_word: extern declarations
+
+subst.c
+	- expand_oneword: detect whether VALUE appears to be a key-value
+	  pair compound assignment and call the appropriate function to expand
+	  each word in the resulting list. Fixes inconsistency reported by
+	  oguzismailuysal@gmail.com
+
+				   12/12
+				   -----
+subst.c
+	- command_substitute: don't reset pipeline_pgrp to shell_pgrp if we
+	  are already forked to run a command (SUBSHELL_FORK). Fixes SIGINT
+	  in command substitution in here-document in forked child issue
+	  reported by oguzismailuysal@gmail.com
+
+				   12/18
+				   -----
+execute_cmd.c
+	- execute_pipeline: execute the lastpipe code even if prev == 0. It
+	  can only be 0 here if stdin was closed when this function was
+	  executed
+	- execute_pipeline: if prev == 0, set lstdin to a sentinel (-1) that
+	  means to close fd 0 after executing the command, and call close(prev)
+	  before restoring stdin. restore_stdin now understands -1, and closes
+	  fd 0. Fixes issue reported by Tomas Janousek <tomi@nomi.cz>
+
+				   12/21
+				   -----
+doc/bashref.texi
+	- PROMPT_COMMANDS: clean up a couple of remaining instances of this
+	  name. Report from Eli Schwartz <eschwartz@archlinux.org>
+
+				   12/26
+				   -----
+subst.c
+	- command_substitute: make sure that the child process always has
+	  pipeline_pgrp == shell_pgrp: if pipeline_pgrp is non-zero when we
+	  get to the child, meaning that we're part of an already-forked
+	  child that is, for instance, running redirections, we need to reset
+	  shell_pgrp to it to preserve the invariant. Fixes bug with terminal
+	  being set to the incorrect pgrp reported by oguzismailuysal@gmail.com
+
+				   12/29
+				   -----
+configure.ac,builtins/shobj-conf,m4/threadlib.m4
+	- midnightbsd: update auto-configuration to treat MidnightBSD like
+	  FreeBSD. From https://savannah.gnu.org/patch/?10006
+
+				   12/30
+				   -----
+examples/loadables/stat.c
+	- stattime: use strftime with a default format or the format supplied
+	  with the -F option to format the file time information
+	- stat_builtin: now takes a -F fmt option for a strftime format string;
+	  change to function calling sequences to pass the format down to
+	  stattime
+
+examples/loadables/Makefile.in
+	- stat: now built and installed by default
+
+				   12/31
+				   -----
+command.h
+	- SUBSHELL_IGNTRAP: new flag value
+
+jobs.c
+	- make_child: set SUBSHELL_IGNTRAP in subshell_environment in the
+	  child process, meaning that we should not execute trap handlers for
+	  trapped signals
+
+execute_cmd.c
+	- execute_in_subshell, execute_simple_command, execute_disk_command:
+	  make sure to unset SUBSHELL_IGNTRAP after a child process restores
+	  the original signal dispositions
+	- execute_simple_command: make sure to set SUBSHELL_IGNTRAP after
+	  make_child returns and we're setting subshell_environment directly
+
+subst.c
+	- command_substitute,process_substitute: unset SUBSHELL_IGNTRAP after
+	  the child process has reset the trapped signal dispositions
+
+trap.c
+	- trap_handler: if we get a signal for which we have set a trap, but
+	  SUBSHELL_IGNTRAP is set in subshell_environmnent, make sure we
+	  restore the original signal disposition and resend the signal to
+	  ourselves. Fixes issue reported by Nikolay Borisov <nborisov@suse.com>
+	  (or at least makes the race window much smaller)
+
+sig.c
+	- initialize_terminating_signal: set the original signal handler from
+	  the return value from sigaction; a minor optimization that saves a
+	  system call or two
+
+				 1/5/2021
+				 --------
+builtins/declare.def
+	- declare_internal: make some option combinations that don't make
+	  sense errors (e.g., -f and -a/-A/-i/-n)
+	- declare_internal: if we build a new variable name by expanding the
+	  value of a nameref variable, make sure to chop the `+' in a `+='
+	  off before going on
+
+				    1/7
+				    ---
+doc/{bash.1,bashref.texi}
+	- bind: add an example to the synopsis making it clear that you can
+	  use any readline command line as a non-option argument, as it says
+	  in the text. From a report from Dan Jacobson <jidanni@jidanni.org>
+
+				   1/12
+				   ----
+locale.c
+	- local_shiftstates -> locale_shiftsates in the non-multibyte code
+	  branch. Reported by Henry Bent <henry.r.bent@gmail.com>
+
+subst.c
+	- expand_compound_assignment_word: make sure to call dispose_words on
+	  the WORD_LIST * returned from expand_oneword after turning it back
+	  into a string. Fixes memory leak reported by Alexander Mescheryakov
+	  <alexander.s.m@gmail.com>
+
+				   1/13
+				   ----
+variables.c
+	- bind_variable_internal: when performing an assignment to a subscripted
+	  array variable that was the value of a nameref (used in the original
+	  assignment), don't call make_variable_value on the value, since that
+	  messes up +=. Just call assign_array_element and let that take care
+	  of calling make_variable_value appropriately. Fixes bug reported by
+	  Oguz <oguzismailuysal@gmail.com>
+
+				   1/14
+				   ----
+findcmd.c
+	- search_for_command: if `checkhash' is set, don't add non-executable
+	  files to the command hash table, since we will just remove them
+	  later
+
+lib/sh/winsize.c
+	- get_new_window_size: set *rp and *cp even if READLINE is not defined
+
+				   1/15
+				   ----
+lib/sh/winsize.c
+	- get_new_window_size: call rl_set_window_size only if we can determine
+	  we're using readline: an interactive shell without no-line-editing,
+	  or if we've already initialized readline, presumably in a non-
+	  interactive shell 
+
+support/Makefile.in
+	- man2html: add LDFLAGS_FOR_BUILD to the recipe. Report from
+	  Jeffrey Walton <noloader@gmail.com>
+
+				   1/17
+				   ----
+lib/readline/misc.c
+	- rl_operate_and_get_next: fix old K&R function declaration. Report
+	  from Tom Tromey <tom@tromey.com>
+
+lib/readline/readline.c
+	- _rl_internal_char_cleanup: move code that cleans up the active region
+	  and deactivates the mark inside this function so callback mode
+	  applications get the intended functionality. Report and fix from
+	  sparrowhawk996@gmail.com
+
+lib/readline/bind.c
+	- rl_parse_and_bind: when using the arithmetic comparison operators on
+	  the version, make sure to invert the tests so that we stop parsing
+	  if the test fails. Report and fix from Tom Tromey <tom@tromey.com>
+
+				   1/19
+				   ----
+Makefile.in
+	- pipesize.h: add dependency on ${BUILTINS_LIBRARY} to avoid parallel
+	  makes trying to create it twice. Report and fix from
+	  Richard Purdie <richard.purdie@linuxfoundation.org>
+
+				   1/21
+				   ----
+subst.c
+	- param_expand: if a nameref expands to array[@] or array[*], make sure
+	  to call chk_atstar so the right variables are set to split the
+	  result. Report from Oguz <oguzismailuysal@gmail.com>
+
+				   1/22
+				   ----
+builtins/declare.def
+	- Rewrote to reduce complexity. Still needs some work.
+
+lib/readline/*.h, lib/tilde/tilde.h
+	- PARAMS: remove, rely on compilers understanding function prototypes
+
+lib/readline/{undo.c,histlib.h}
+	 - _hs_replace_history_data: move extern declaration to histlib.h
+
+lib/readline/readline.c
+	- _rl_parse_colors: instead of an extern declaration for this, include
+	  "parse-colors.h" for it
+
+lib/readline/{histfile.c,histlib.h}
+	- _hs_append_history_line: move extern declaration to histlib.h
+
+lib/readline/history.h
+	- HS_HISTORY_VERSION: define to 0x0801 (current library version) if
+	  it's not already defined. We conditionally define it in case an
+	  application has (unwisely) chosen to use it, since the history
+	  library doesn't do anything with it yet
+
+lib/readine/{rlprivate.h,{search,misc,readline}.c}
+	- _rl_free_history_entry: add extern declaration to rlprivate.h, remove
+	  extern declaration from c source files. Use HS_HISTORY_VERSION as a
+	  sentinel that it's ok to use HIST_ENTRY in rlprivate.h
+
+lib/readline/{rlprivate.h,{isearch,search,undo}.c}
+	- _rl_saved_line_for_history: add extern declaration to rlprivate.h,
+	  remove extern declaration from c source files, using HS_HISTORY_VERSION
+	  in the same way
+
+				   1/24
+				   ----
+lib/readline/signals.c
+	- _rl_handle_signal: make sure that all sigprocmask calls are protected
+	  by HAVE_POSIX_SIGNALS. Report and fix from Tom Tromey <tom@tromey.com>
+
+				   1/26
+				   ----
+lib/readline/callback.c
+	- rl_callback_read_char: make sure rl_linefunc is non-NULL before
+	  calling through the pointer. The line function could have been
+	  removed by the application before readline processes any typeahead
+	  input. Bug reported by Matthias Klose <doko@debian.org>, pointer
+	  to root cause from Koichi Murase <myoga.murase@gmail.com>
+
+lib/glob/glob.c
+	- skipname,wskipname: put in some additional checks for `.' to ensure
+	  that we don't get false positives (or incomplete tests) that can 
+	  affect the results of extglob patterns. Reported by
+	  gregrwm <rhn-users@greatlakedata.com>
+
+				   1/27
+				   ----
+lib/glob/glob.c
+	- extglob_skipname,wextglob_skipname: fixed an off-by-one error (SE
+	  was being set to one character before the end of the pattern string,
+	  not the null character at the end of the pattern string like other
+	  callers of glob_patscan) that caused the last character of the last
+	  subpattern to be cut off when calling skipname
+	- extglob_skipname,wextglob_skipname: some cleanups so the code is
+	  closer to identical for the single-byte and wide character versions
+
+				    2/1
+				    ---
+execute_cmd.c
+	- execute_simple_command: in posix mode, if we have a variable
+	  assignment error while assigning into the temporary environment (e.g.,
+	  assigning to a readonly variable), a non-interactive shell running a
+	  special builtin exits; a non-interactive shell running anything else
+	  jumps back to the top level. A shell compiled with -DSTRICT_POSIX
+	  exits unconditionally.
+	- execute_simple_command: make sure posix mode sets $? to non-zero
+	  if a variable assignment error occurs preceding a non-special builtin
+
+subst.c
+	- do_assignment_statements: take the code from expand_word_list_internal
+	  that performs assignment statements, either standalone or preceding 
+	  simple command names, and factor it out into this function
+	- expand_word_list_internal: call do_assignment_statements where
+	  appropriate
+
+				    2/2
+				    ---
+lib/glob/glob.c
+	- dequote_pathname: fix function definition for non-multibyte systems.
+	  Report and fix from Marc Aurèle La France <tsi@tuyoix.net>
+
+Makefile.in,doc/Makefile.in
+	- for certain targets, remove files before creating them to deal with
+	  symlinked build trees.
+	  Report and fix from Marc Aurèle La France <tsi@tuyoix.net>
+
+examples/loadables/accept.c
+	- include limits.h before typemax.h
+	  Report and fix from Marc Aurèle La France <tsi@tuyoix.net>
+
+builtins/gen-helpfiles.c
+	- if USING_BASH_MALLOC is defined, make sure to undefine malloc as well
+	  as free. Fixes bug reported by George R Goffe <grgoffe@yahoo.com>
+
+builtins/Makefile.in
+	- install-help: now depends on $(HELPFILES_TARGET) so we make sure the
+	  separate helpfiles are created before we try to install them if we
+	  don't go through the `all' makefile target
+
+configure.ac
+	- HELPDIR: now ${datadir}/bash/helpfiles
+
+				    2/3
+				    ---
+parse.y
+	- parse_string_to_word_list: before expanding a compound assignment
+	  statement body, make sure to save any alias that's currently being
+	  expanded. Restore the alias after the compound assignment is parsed.
+	  Reported back in 11/2020 by Alex fxmbsw7 Ratchev <fxmbsw7@gmail.com>
+
+				    2/4
+				    ---
+lib/readline/histexpand.c
+	- history_expand_internal: when calling the history_inhibit_expansion
+	  function, make sure to call it using the string as we've expanded it
+	  to that point (RESULT), adding the expansion and next characters
+	  temporarily, since we make expansion decisions based on what we've
+	  accumulated, not what we started with. This makes things like
+	  echo abc!$!$ work, where before the second `!' inhibited expansion
+	  because bash_history_inhibit_expansion mistakenly took it as the
+	  second character in a `$!' word expansion. Fixes bug reported back
+	  in 10/2020 by Paul Fox <paul.d.fox@gmail.com>
+
+array.h
+	- array_pop: instead of calling array_dispose_element from this macro,
+	  just call array_shift with the AS_DISPOSE flag
+
+				    2/5
+				    ---
+bashhist.c
+	- shell_comment: move condition to return 0 if the delimiter stack is
+	  not empty or the shell is parsing a here document into the function
+	  itself, don't have the callers check so the check is in one place.
+	  Fixes bug reported by Oguz <oguzismailuysal@gmail.com>
+
+array.h,variables.c
+	- ARRAY_ELEMENT_REPLACE: convenience define for modifying an array
+	  element's value
+
+variables.c
+	- pop_args: a couple of code simplifications
+
+				    2/7
+				    ---
+lib/malloc/malloc.c
+	- pagesz: at least MALLOC_PAGESIZE_MIN (4096) bytes
+	- union mhead: now 16-byte aligned on all systems, 32-bit and 64-bit
+	  pointers
+	- binsizes: since the smallest allocation overhead is now 16 bytes,
+	  redo the buckets so binsizes[0] == 32; adjust the thresholds for
+	  split/coalesce/prepopulate/mmap (NBUCKETS = 28; STARTBUCK = 0).
+	  Sizes stay pretty much the same; indices change
+	- consistently use MALLOC_SIZE_T instead of long/unsigned int/int
+	- use MAGIC8_NUMBYTES as the length of the mh_magic8 buffer, in case
+	  it changes later for alignment
+	- internal_remap: new function, calls mremap to reallocate a chunk of
+	  memory allocated using mmap(); called from internal_realloc if the
+	  old size and new size are both bigger than the mmap threshold
+	- internal_realloc: call internal_remap if the old size and new size
+	  are both above the threshold where we use mmap for allocation
+
+				   2/10
+				   ----
+include/timer.h
+	- new file, declaration for a timer struct to be used by a set of
+	  functions to implement timers using SIGALRM or select/pselect
+
+lib/sh/timers.c
+	- new file, set of functions to manipulate timer objects and timeouts
+	  using SIGALRM or select/pselect. Inspired by a patch from
+	  Koichi Murase <myoga.murase@gmail.com>. Not used yet
+
+				   2/11
+				   ----
+builtins/read.def
+	- read_builtin: if there is a timeout set, block SIGCHLD around calls
+	  to zread and its siblings, or calls to readline for `read -e', so
+	  SIGCHLD (and the consequent waitpid) doesn't interrupt the read.
+	  Fixes bug reported by Koichi Murase <myoga.murase@gmail.com>, but
+	  there may be a different fix coming
+
+Makefile.in,builtins/Makefile.in
+	- fix up dependencies, especially on builtins.h and builtext.h
+
+
+				   2/12
+				   ----
+lib/readline/input.c
+	- rl_read_key: if we set rl_done == 1, set RL_STATE_DONE as well
+	  Reported by Koichi Murase <myoga.murase@gmail.com>
+
+lib/readline/isearch.c
+	- _rl_search_getchar: only call _rl_read_mbstring if rl_read_key returns
+	  >= 0, avoid some work
+
+lib/readline/vi_mode.c
+	- _rl_vi_callback_change_char,_rl_vi_change_char: don't overwrite the
+	  last replacement string if _rl_vi_callback_getchar returns -1.
+	  It will likely make no difference, since the next read will return
+	  an error or EOF, but being careful
+	- rl_vi_overstrike: if _rl_overwrite_char doesn't return 0, break out
+	  of the loop
+
+lib/readline/text.c
+	- _rl_overwrite_char: return 1 if _rl_read_mbstring returns < 0 so
+	  we don't try to insert garbage
+
+bashline.c
+	- posix_edit_macros: handle rl_read_key() returning <= 0
+
+				   2/15
+				   ----
+parse.y
+	- read_comsub: make sure to turn on the LEX_RESWDOK flag if we are in
+	  a case statement and read a `)', since we can get a valid `esac'.
+	  Fixes bug reported by Oguz <oguzismailuysal@gmail.com>
+	- read_comsub: if we're in a case statement, recognize `}' as a
+	  reserved word and set the LEX_RESWDOK flag for the next word, since
+	  we can get an esac (or another reserved word) after it
+
+				   2/16
+				   ----
+parse.y
+	- reserved_word_acceptable: add ARITH_CMD and COND_END to the list of
+	  tokens that can precede a reserved word, so you can use reserved
+	  words after ((...)) and [[...]].
+	  Reported by Koichi Murase <myoga.murase@gmail.com>
+
+				   2/17
+				   ----
+parse.y
+	- parse_comsub: use new LEX_CASEWD flag to track when we are reading
+	  the WORD in `case WORD in' and turn on the LEX_RESWDOK flag when
+	  that word ends. This allows $(case x in esac), which no one uses.
+	- parse_comsub: use LEX_PATLIST flag to track when we are reading a
+	  case pattern list so `|' doesn't turn on the LES_RESWDOK flag
+	- parse_comsub: case_level: simple counter to count the number of esacs
+	  we need to see before we're no longer in a case statement; analog of
+	  esacs_needed_count from the lexer
+
+				   2/19
+				   ----
+parse.y
+	- CHECK_FOR_RESERVED_WORD: don't return ESAC if we read `esac' after a
+	  left paren in a case pattern list. From an austingroup-bugs discussion
+	  about https://www.austingroupbugs.net/view.php?id=1454
+	- parse_comsub: if we read a `(' while looking for a case pattern list
+	  and LEX_CKESAC is set, we have a leading left paren in the pattern
+	  list and should turn off LEX_CKESAC so (esac) doesn't prematurely
+	  terminate the case command. From an austingroup-bugs discussion
+	  about https://www.austingroupbugs.net/view.php?id=1454
+
+				   2/26
+				   ----
+builtins/history.def
+	- history_builtin: when checking negative offsets to -d, which are
+	  supposed to count back from the end of the history list, check the
+	  range against 0 instead of history_base, because the calculation is
+	  done against history_length, which is independent of history_base.
+	  Report and fix from Christopher Gurnee <chris@gurneeconsulting.net>
+
+				   2/28
+				   ----
+doc/bashref.texi
+	- replaced a number of uses of @var with a mixture of @env and @dfn
+	  to better match up with the texinfo standards
+
+doc/{bash.1,bashref.texi}
+	- clarify some aspects of the coproc description, especially the
+	  use of NAME and when it's optional
+
+				    3/1
+				    ---
+subst.c
+	- read_comsub: fix off-by-one error in mbrtowc that causes a read one
+	  character past the end of buf. Report and fix from
+	  Platon Pronko <platon7pronko@gmail.com> in
+	  https://savannah.gnu.org/patch/?10035

+builtins/ulimit.def
+	- ulimit_builtin: Posix compatibility: if the last command specified
+	  by an option does not have an option argument, but there is an
+	  operand remaining after all the options are parsed, treat the
+	  operand as an argument to that last command. From an austin-group
+	  discussion and a Geoff Clare suggestion back in November, 2020.

+
+builtins/exec.def
+	- exec_builtin: instead of using restore_original_signals to completely

+	  preserved. Then if the exec fails (and we're not exiting) we can
+	  look at the trap strings and see how to restore the trap state.
+	  This calls restore_traps after reinitializing the shell signal

+	  _rl_completion_prefix_display_length, add explicit check for
+	  prefix_bytes being longer since print_filename passes it through

+	  if we're not going to exit immediately out of this function
+
+				   7/28
+				   ----
+parse.y
+	- parse_comsub: if the compatibility level is <= 51, set extglob while

+	  caught but valid patterns are let through and can be evaluated at
+	  runtime, when extglob may have been set. If it isn't set, it will
+	  still be a parser error when the command substitution is executed.
+	  Fixes report from Sam James <sam@gentoo.org> about gentoo scripts.
+	- reset_parser: set extended_glob from global_extglob if the parser
+	  state includes PST_CMDSUBST
+	- xparse_dolparen: set global_extglob but don't modify extended_glob,
+	  so parse errors can be caught before forking a child for command
+	  substitution, as part of word expansion, but after extglob may have
+	  been set by command execution (e.g., in a shell function)

+lib/readline/nls.c

+	- _rl_set_localevars: new function, code from _rl_init_eightbit that
+	  checks the current locale (passed as an argument) and sets the
+	  various locale-aware variables based on it. It accepts a second
+	  argument: FORCE. If non-zero, it means to restore the default "C"
+	  locale values if the locale is "C" or "POSIX", now that this
+	  function can be called multiple times
+	- _rl_init_eightbit: now just calls _rl_init_locale and
+	  _rl_set_localevars
+	- _rl_reset_locale: new function, checks whether our the locale has
+	  changed since we last called _rl_init_locale to set our internal
+	  idea of its value. If it has changed, call _rl_set_localevars with
+	  the new locale and a FORCE argument of 1 to change the

+parse.y
+	- parse_comsub: don't clear the pushed string list; we might need it to

+	  case we used it. From
+	  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1018727
