+Version 2.8.7 contains no user-visible changes.
+
+User-visible changes in version 2.8.6:
+
+* New diff3 option --strip-trailing-cr.
+
+* With -N and -P, inaccessible empty regular files (the kind of files
+  that 'patch' creates to indicate nonexistent backups) are now
+  treated as nonexistent when they are in the 'backup' file position.
+
+* If multiple SKIP values are given to cmp, e.g., `cmp -i 10 -i 20',
+  cmp now uses the maximal value instead of the last one.
+
+* diff now omits the ".000000000" on hosts that do not support
+  fractional time stamps.
+
+Version 2.8.5 was not publicly released.
+
+User-visible changes in version 2.8.4:
+
+* Diff now simply prints "Files A and B differ" instead of "Binary
+  files A and B differ".  The message is output if either A or B
+  appears to be a binary file, and the old wording was misleading
+  because it implied that both files are binary, which is not
+  necessarily the case.
+
+User-visible changes in version 2.8.3:
+
+* New locale: en_US.
+
+User-visible changes in version 2.8.2:
+
+* New diff and sdiff option:
+  --tabsize=COLUMNS
+* If --ignore-space-change or --ignore-all-space is also specified,
+  --ignore-blank-lines now considers lines to be empty if they contain
+  only white space.
+* More platforms now handle multibyte characters correctly when
+  excluding files by name (diff -x and -X).
+* New locales: hu, pt_BR.
+
+User-visible changes in version 2.8.1:
+
+* Documentation fixes.
+
+User-visible changes in version 2.8:
+
+* cmp and diff now conform to POSIX 1003.1-2001 (IEEE Std 1003.1-2001)
+  if the underlying system conforms to POSIX and if the _POSIX2_VERSION
+  environment variable is set to 200112.  Conformance removes support
+  for `diff -NUM', where NUM is a number.  Use -C NUM or -U NUM instead.
+* cmp now supports trailing operands SKIP1 and SKIP2, like BSD cmp.
+* cmp -i or --ignore-initial now accepts SKIP1:SKIP2 option value.
+* New cmp option: -n or --bytes.
+* cmp's old -c or --print-chars option has been renamed;
+  use -b or --print-bytes instead.
+* cmp now outputs "byte" rather than "char" outside the POSIX locale.
+* cmp -l's index column width now adjusts to fit larger (or smaller) files.
+* cmp -l -s and cmp -s -l are not allowed.  Use cmp -s or cmp -l instead.
+* diff uses ISO 8601 style time stamps for output times (e.g. "2001-11-23
+  16:44:36.875702460 -0800") unless in the C or POSIX locale and the
+  -c style is specified.
+* diff's -I and -F options use the regexp syntax of grep, not of Emacs.
+* diff now accepts multiple context arguments, and uses their maximum value.
+* New diff and sdiff options:
+  -E  --ignore-tab-expansion
+  --strip-trailing-cr
+* New diff options:
+  --from-file=FILE, --to-file=FILE
+  --ignore-file-name-case
+  --no-ignore-file-name-case
+* New diff3 and sdiff option:
+  --diff-program=PROGRAM
+* The following diff options are still accepted, but are no longer documented.
+  They may be withdrawn in future releases.
+  -h (omit; it has no effect)
+  -H (use --speed-large-files instead)
+  -L (use --label instead)
+  -P (use --unidirectional-new-file instead)
+  --inhibit-hunk-merge (omit; it has no effect)
+* Recursive diffs now sort file names according to the LC_COLLATE locale
+  category if possible, instead of using native byte comparison.
+* Recursive diffs now detect and report directory loops.
+* Diff printf specs can now use the "0" and "'" flags.
+* The new sdiff interactive command `ed' precedes each version with a header.
+* On 64-bit hosts, files larger than 2 GB can be compared.
+* Some internationalization support has been added, but multibyte locales
+  are still not completely supported yet.
+* Some diagnostics have been reworded slightly for consistency.
+  Also, `diff -D FOO' now outputs `/* ! FOO */' instead of `/* not FOO */'.
+* The `patch' part of the manual now describes `patch' version 2.5.4.
+* Man pages are now distributed and installed.
+* There is support for DJGPP; see the 'ms' subdirectory and the files
+  m4/dos.m4 and */setmode.*.
