rsync 2.5.3 (not released yet)
+ SECURITY FIXES:
+
+ * Make sure that supplementary groups are removed from a server
+ process after changing uid and gid. (Ethan Benson)
+
ENHANCEMENTS:
* Command to initiate connections is only shown with -vv, rather
what was historically used so as not to break scripts that try
to parse the output.
+ * Added --no-whole-file and --no-blocking-io options (Dave Dykstra)
+
+ * Made the --write-batch and --read-batch options actually work
+ and added documentation in the man page (Jos Backus)
