 * The diffutils 2.7 documentation for `patch' is obsolete; this should be
   fixed in diffutils 2.8.  Until then, see `patch --help' or `man patch'.
 
+Changes in version 2.3:
+
+* Unless the POSIXLY_CORRECT environment variable is set:
+
+  - `patch' now distinguishes more accurately between empty and
+    nonexistent files if the input is a context diff.
+    A file is assumed to not exist if its context diff header
+    suggests that it is empty, and if the header timestamp
+    is within 24 hours of 1970-01-01 00:00:00 UTC.
+  - Files that ``become nonexistent'' after patching are now removed.
+    When a file is removed, any empty ancestor directories are also removed.
+
+* Files are now automatically gotten from RCS and SCCS
+  if the -g or --get option is specified,
+  or if the PATCH_GET environment variable is set
+  and the -G or --no-get option is not specified.
+
+* If the PATCH_VERSION_CONTROL environment variable is set,
+  it overrides the VERSION_CONTROL environment variable.
+
+* The method used to intuit names of files to be patched is now as follows:
+
+  - Take the old and new names from the context header if present,
+    and take the index name from the `Index:' line if present.
+    Consider the file names to be in the order (old, new, index).
+  - If some named files exist, use the first one if POSIXLY_CORRECT is set,
+    the best one otherwise.
+  - If no named files exist, some names are given, POSIXLY_CORRECT is not set,
+    and the patch appears to create a file, then use the best name
+    requiring the creation of the fewest directories.
+  - Otherwise, ask the user for a file name.
+
+  The ``best'' of a nonempty list of file names is defined as follows:
+    - Take the names with the fewest path name components;
+      of those, take the names with the shortest basename;
+      of those, take the shortest names;
+      of those, take the first name.
+
+* The new --binary option makes `patch' read and write files in binary mode.
+  This option has no effect on POSIX-compliant hosts;
+  it is useful only in on operating systems like DOS
+  that distinguish between text and binary I/O.
+
+* The environment variables TMP and TEMP are consulted for the name of
+  the temporary directory if TMPDIR is not set.
+
+* A port to MS-DOS and MS-Windows is available; see the `pc' directory.
+
+* Backup file names are no longer ever computed by uppercasing characters,
+  since this isn't portable to systems with case-insensitive file names.

 Changes in version 2.2:
 
 * Arbitrary limits removed (e.g. line length, file name length).
