+ - Added the --delete-during (--del) option which will delete files
+ from on the receiving side incrementally as each directory in the
+ transfer is being processed (which makes it more efficient than
+ the default, before-the-transfer behavior of --delete).
+
+ - Added the --filter (-f) option and its helper option, -F. Filter
+ rules are an extension to the existing include/exclude handling
+ that also supports nested filter files as well as per-directory
+ filter files (like .cvsignore, but with full filter-rule parsing).
+ This new option was chosen in order to ensure that all existing
+ include/exclude processing remained 100% compatible with older
+ versions.
