Release Notes: Support has been added for diff3-style merges and for most features of the "diff --git" format, including renames and copies, permission changes, and symlink diffs, but not including binary diffs. Filenames can now be double-quoted as C string literals. Normal patches are no longer applied to symlinks (this behavior can be reverted with the new "--follow-symlinks" option). Timestamps with timezones are now honored correctly. Messages have been improved. Behavior and handling in several scenarios has been improved. Various minor bugs have been fixed.
Release Notes: The "check" makefile target was added. The --merge option was added. Reject files now can be used as regular patches. The original version of a file that is patched more than once is backed up, and at most only one reject file is made. The -r option now works correctly. Rejected hunks come out in unified diff format if the input patch was of that format. Various bugs were fixed.
