-Changes in version 1.22:
+Changes in version 1.23:
 
-The option '-e, --reproduce', which can recover a missing (zeroed) sector in
-a lzip file, has been added. For it to work, two things are required:
-  - The same version of the lzip tool that created the file.
-  - A reference file containing the uncompressed data corresponding to the
-    missing compressed data of the zeroed sector, plus some context data
-    before and after them.
-Thanks to Nissanka Gooneratne for his help in testing the reproduce mode.
+Decompression time has been reduced by 5-12% depending on the file.
 
-The options '--lzip-level', '--lzip-name', and '--reference-file', auxiliary
-to '-e, --reproduce', have been added.
+In case of error in a numerical argument to a command line option, lziprecover
+now shows the name of the option and the range of valid values.
 
-Option aliases '--dump-tdata', '--remove-tdata', and '--strip-tdata' have
-been removed.
+Options '--dump' and '--strip' now refuse to write compressed data to a
+terminal except when dumping trailing data with '--dump=tdata'.
 
-When decompressing or testing, lziprecover now reports an error if a file
-name is empty (lziprecover -t "").
+The option '-U, --unzcrash' now requires an argument: '1' to test 1-bit
+errors, or 'B<size>' to test zeroed blocks.
 
-Option '-o, --output' now behaves like '-c, --stdout', but sending the
-output unconditionally to a file instead of to standard output. See the new
-description of '-o' in the manual. This change is backwards compatible only
-when decompressing from standard input alone. Therefore commands like:
-  lziprecover -d -o foo - bar.lz < foo.lz
-must now be split into:
-  lziprecover -d -o foo - < foo.lz
-  lziprecover -d bar.lz
-or rewritten as:
-  lziprecover -d - bar.lz < foo.lz > foo
+The memory tester now allocates the dictionary once per member instead of
+doing it for each test. This makes '-U, --unzcrash' about two times faster
+on my machine on files with an uncompressed size larger than about 30 MB.
 
-When using '-c' or '-o', lziprecover now checks whether the output is a
-terminal only once.
+'-W, --debug-decompress' now continues decompressing the members following
+the damaged member if it has been fully decompressed (just failed with a CRC
+mismatch).
 
-Lziprecover now does not even open the output file if the input file is a
-terminal.
+The tool unzcrash now uses execvp instead of popen to avoid invoking /bin/sh
+and run faster. It also prints byte or block position in messages.
 
-'--ignore-errors' now makes '--decompress' and '--test' ignore data errors
-and continue decompressing the remaining members in the file, keeping input
-files unchanged.
+Several descriptions have been improved in manual, '--help', and man page.
 
-'--ignore-errors --range-decompress' now decompresses a truncated last
-member. It also returns 0 if only ignored errors (format errors or data
-errors) are found.
-
-'--ignore-errors' now considers that any fragment of file starting with a
-valid header and large enough to be a member is a (corrupt) member, not a
-gap, even if it lacks a valid trailer.
-
-The words 'decompressed' and 'compressed' have been replaced with the
-shorter 'out' and 'in' in the verbose output when decompressing or testing.
-
-Several compiler warnings have been fixed. (Reported by Nissanka Gooneratne).
-
-Option '--list' now reports corruption or truncation of the last header in a
-multimenber file specifically instead of showing the generic message "Last
-member in input file is truncated or corrupt."
-
-The debug options '-E, --debug-reproduce', '-M, --md5sum', and
-'-U, --unzcrash' have been added.
-
-The commands needed to extract files from a tar.lz archive have been
-documented in the manual, in the output of '--help', and in the man page.
-
-The new chapter 'Reproducing one sector' has been added to the manual.
-
-The new sections 'Merging with a backup' and 'Reproducing a mailbox' have
-been added to the manual.
-
-The debug options for experts have been documented in the manual.
-
-Lzip 1.16 (or clzip 1.6) or newer is required to run the tests.
-
-9 new test files have been added to the testsuite.
+The texinfo category of the manual has been changed from 'Data Compression'
+to 'Compression' to match that of gzip. (Reported by Alfred M. Szmidt).
