+
+ - The filter rules now support a perishable ("p") modifier that marks rules
+ that should not have an effect in a directory that is being deleted. e.g.
+ -f '-p .svn/' would only affect "live" .svn directories.
+
+ - Rsync checks all the alternate-destination args for validity (e.g.
+ --link-dest). This lets the user know when they specified a directory
+ that does not exist.
+
+ - If we get an error setting the time on a symlink, we don't complain about
+ it anymore (since some operating systems don't support that, and it's not
+ that important).
+
+ - Protocol 30 now uses MD5 checksums instead of MD4.
+
+ - Changed the --append option to not checksum the existing data in the
+ destination file, which speeds up file appending.
+
+ - Added the --append-verify option, which works like the older --append
+ option (verifying the existing data in the destination file). For
+ compatibility with older rsync versions, any use of --append that is
+ talking protocol 29 or older will revert to the --append-verify method.
+
+ - Added the --contimeout=SECONDS option that lets the user specify a
+ connection timeout for rsync daemon access.
+
+ - Documented and extended the support for the RSYNC_CONNECT_PROG variable
+ that can be used to enhance the client side of a daemon connection.
+
+ - Improved the dashes and double-quotes in the nroff manpage output.
+
+ - Rsync now supports a lot more --no-OPTION override options.
