diffstat 1.51
correct suffix-check for ".xz" files as command-line parameters rather
than as piped input (report by Moritz Barsnick).
06-Oct-2009
diffstat 1.50
build/test fixes for MSYS (MinGW)
improve configure check for get_unlocked function.
use $TMPDIR for path of temporary file used in decompression.
correct else-condition for detecting compression type (patch by Zach
Hirsch).
31-Aug-2009
diffstat 1.49
improve lzma support, add support for xz (patch by Eric Blake).
add special case for no-newline message from some diff's (Ubuntu
#269895).
improve configure check for getopt header.
add configure special case for HPUX 11 with _XOPEN_SOURCE definition.
update config.guess, config.sub
11-Aug-2009
diffstat 1.48
add decompression tests for lzma and pack file types.
check for zcat and uncompress in preference to "compress -dc".
modify to check the first few bytes of standard input, and use a
corresponding decompression utility if the stream appears to be
compressed. This requires making a temporary copy of the data
(Debian #491575).
add -N option, to truncate filenames.
use getc_unlocked() rather than fgetc_unlocked()
modify to recognize Perforce-style diffs (patch by Ed Schouten).
update configure macros to improve compiler warning checks, use
$PATH_SEPARATOR rather than $PATH_SEP (for consistency with some
autoconf versions),
fix typo in configure --with-install-prefix option (report by
Dagobert Michelsen).
update config.guess, config.sub
29-Mar-2009
diffstat 1.47
modify to work with patch ".rej" files, which do not have a header to
tell which file is affected.
fix typo in usage message (reports by Moritz Barsnick, John McNamara,
Richard Quadling).
06-Aug-2008
diffstat 1.46
add "-S", "-D" and "-m" options to provide a way to show the amount
of difference relative to the total sizes of the files.
add "-q" option (Debian #488248, patch by Greg Norris).
04-Sep-2007
diffstat 1.45
add "-b" option (Debian #379380, patch by Greg Norris).
26-Aug-2007
diffstat 1.44
add a check for default-diff output, e.g., "diff foo bar|diffstat",
which has no "diff" command in the output for diffstat to guess that
a diff is beginning.
add a check after completing a chunk for unified diff to ensure that
the next line either begins another chunk for the diff, or starts
another diff, e.g., a context diff (report by Adrian Bunk).
add configure options for leak-checking valgrind, etc.
use install-sh rather than install.sh
updated config.guess and config.sub
updated configure macros CF_GCC_ATTRIBUTES CF_GCC_WARNINGS CF_MSG_LOG
CF_PATH_SYNTAX CF_VERBOSE CF_XOPEN_SOURCE
16-Jul-2006
diffstat 1.43
fix to avoid modifying data which is being used by tsearch() for
ordering the binary tree (report by Adrian Bunk).
02-Jul-2006
diffstat 1.42
do not ignore pathnames in /tmp/, since some tools create usable
pathnames for both old/new files there (Debian #376086).
correct ifdef for fgetc_unlocked().
updated configure macros CF_GCC_VERSION, CF_PATH_SYNTAX and
CF_XOPEN_SOURCE
add configure check for compress, gzip and bzip2 programs that may be
used to decompress files.

improve searching of long sorted lists using tsearch()
improve configure-script checks for Intel compiler warnings.
10-Apr-2005
diffstat 1.39
change order of merging and prefix-stripping so stripping all prefixes,
e.g., with -p9, will be sorted as expected (patch by Jean Delvare).
correct a reference to freed memory after merging found with valgrind.
16-Jan-2005
diffstat 1.38
add makefile.wnt, etc., for win32 port.
fix "make check" to work even when PATH or the build directory has
spaces in it (patch by Eric Blake).
add support for '--help' and '--version' command line arguments, for a
consistent interface with GNU tools, and still compatible to POSIX
requirements on utility options (patch by Eric Blake).
18-Dec-2004
modify makefile.in and run_test.sh to allow "make check" to be run from
a build directory which is not the same as the source directory, i.e.,
when the configure --srcdir option is used (request by Eric Blake).
modify distribution to include sample of regression tests, so a
"make check" will work (request by Eric Blake).
16-Dec-2004
diffstat 1.37
fix a different case for data beginning with "--" which was treated as
a header line.
14-Dec-2004
diffstat 1.36
Fix allocation problems. Open files in binary mode for reading.
Getopt returns -1, not necessarily EOF. Add const where useful. Use
NO_IDENT where necessary. malloc() comes from <stdlib.h> in standard
systems (Patch by Eric Blake <ebb9@byu.net>.)
08-Nov-2004
diffstat 1.35
modify makefile.in to work with configure --srcdir option (report by
Eric Blake).
minor fix for resync of unified diffs checks for range (line beginning
with '@' without header lines (successive lines beginning with "---"
and "+++") (Debian #264098).
miscellaneous updates for configure script
09-Nov-2003
diffstat 1.34
improve check for certain lines (not those that begin a chunk) that
begin with '-', treating all except "---" as a delete (report by
James Rowe <Jay@jnrowe.uklinux.net>).
minor updates to configure script.
14-Feb-2003
diffstat 1.33
modified to work around a case where the filename+date was incomplete,
i.e., missing one of the components such as the day of the month.
While diffstat does not use the date directly, it helps distinguish
some lines from non-patches (report by Moritz Barsnick
<moritz@barsnick.net>).
add "-h" option (request by Moritz Barsnick).
fix a typo in usage message (report by Moritz Barsnick).
add "-e" and "-o" options to simplify testing on OS/2 EMX.
04-Jan-2003
diffstat 1.32
modified to handle patches generated by makepatch-2.00_09, which uses
both "Index" and "diff" lines (report by D Roland Walker). As a side
effect, the additional merging eliminates occasional reports with
zero differences.
modified to avoid buffer overflows.
fixes for Debian #155000 (did not handle a '-' in first content-column
of a unified diff) and #170947 (option to turn the progress messages
off).
update configure script using aclocal.m4 macros
update makefile.in to improve use of autoconf (report/patch by Nix
<nix@esperi.demon.co.uk>).
20-Aug-2002
diffstat 1.31
add -u, -k options to override diffstat's normal sorting (-u) and
merging (-k) of identical filenames. (-u requested by H Peter Anvin
<hpa@zytor.com>).
09-Aug-2002
diffstat 1.30
allow either '/' or '-' as delimiters in dates, to accommodate gendiff
(report by Rik van Riel <riel@conectiva.com.br>). This corresponds to
the time format used in diffutils 2.8 whose changelog states that this
is ISO 8601 (though online references differ).
10-Oct-2001
diffstat 1.29
add bzip2 (.bz2) suffix as suggested by Gregory T Norris
<haphazard@socket.net> in Debian bug report #82969).
add check for diff from RCS archive where the "diff" lines do not
reference a filename.
29-Mar-2000
diffstat 1.28
Add -c option (to prefix output with '#' comment), eliminating a step
in my script that combines diffstat output with a patch. This is a
workaround for OSF1's broken sed utility.
Check for compressed file suffixes .Z and .gz, read uncompressed data
via pipe (Debian wishlist item #53975 by ch@lathspell.westend.com).
Simplified makefile based on comments by M Sweger
<mikesw@whiterose.net>
Adapted changes from Troy Engel <tengel@sonic.net> as "-f" option.
27-May-1998
diffstat 1.27
Debian diff's don't show dates on the lines where we expect to see
filenames.
Patch 5 (16-Jan-1998)
diffstat 1.26
Change copyright terms.
Accommodate patches w/o tabs in header lines (e.g., from cut/paste).
Still prefer the tabs because otherwise we cannot have spaces in
filenames.
Strip suffixes such as ".orig", to avoid confusing output.
Patch 4 (16-Mar-1996)
diffstat 1.24
Corrected state-transition after "Binary".
Added testing subdirectory
Added -p option.
Handle differences from /tmp (e.g., for X11R5 patches).
Patch 3 (06-May-1995)
Repost whole program to comp.sources.misc (1.17)
Mods to scaling: limit to 1:1 if only a few changes were made; added
logic to accumulate error across +/-/! calls.
added logic to recognize 'rcsdiff -u' output.
Patch 2 (26-Dec-1994)
Strip common pathname prefix (1.15)
Patch 1 (13-Nov-1994)
Test for <string.h> vs <strings.h>
Corrected error in 'match()' that didn't handle properly the case when
an argument was a null string (i.e., blank lines in a unified diff).
Added options '-n' and '-V'
Added patchlev.h, CHANGES files.
Added install.sh, for autoconf 2.1
Patch 0 (13-Jun-1994)
Initial release of 'diffstat' (1.12).
