+ - If a file has a read error on the sending side, the receiver will
+ no longer keep the resulting file unless the --partial option was
+ specified. (Note: both sides must be running 2.6.3 for this to
+ work -- older receivers always keep the file, and older senders
+ don't tell the receiver that the file was not read correctly.)
+
+ - If a file gets resent in a single transfer and the --backup option
+ is enabled, rsync no longer performs a duplicate backup (losing the
+ original file in the process).
