+ - Added the --info=FLAGS and --debug=FLAGS options to allow finer-grained
+ control over what is output. Added an extra type of --progress output
+ using --info=progress2.
+
+ - The --msgs2stderr option can help with debugging rsync by allowing the
+ debug messages to get output to stderr rather than travel via the socket
+ protocol.
+
+ - Added the --delete-missing-args and --ignore-missing-args options to
+ either delete or ignore user-specified files on the receiver that are
+ missing on the sender (normally the absence of user-specified files
+ generates an error).
+
+ - Added a "T" (terabyte) category to the --human-readable size suffixes.
+
+ - Added the --usermap/--groupmap/--chown options for manipulating file
+ ownership during the copy.
+
+ - Added the "%C" escape to the log-output handling, which will output the
+ MD5 checksum of any transferred file, or all files if --checksum was
+ specified (when protocol 30 or above is in effect).
+
+ - Added the "reverse lookup" parameter to the rsync daemon config file to
+ allow reverse-DNS lookups to be disabled.
+
+ - Added a way for more than one group to be specified in the daemon's
+ config file, including a way to specify that you want all of the
+ specified user's groups without having to name them. Also changed the
+ daemon to complain about an inability to set explicitly-specified uid/gid
+ values, even when not run by a super-user.
+
+ - Added a way to reference environment variables in a daemon's config file
+ (using %VAR% references).
+
+ - When replacing a non-dir with a symlink/hard-link/device/special-file,
+ the update should now be done in an atomic manner.
+
+ - Fixed a free of the wrong pointer in uncache_tmp_xattrs() (which only
+ sometimes affects an --xattr transfer when --backup is used).
+
+ - When backing up a file, try to hard-link the file into place so that the
+ upcoming replacement of the destination file will be atomic.
