+ - We try to work around some buggy IPv6 implementations that fail to
+ implement IPV6_V6ONLY. This should fix the "address in use" error
+ that some daemons get when running on an OS with a buggy IPv6
+ implementation. Also, if the new code gets this error, we might
+ suggest that the user specify --ipv4 or --ipv6 (if we think it will
+ help).
+
+ - When the remote rsync dies, make a better effort to recover any error
+ messages it may have sent instead of just dying with a write error
+ trying to send data over the socket.
+
+ - When using --delete and a --backup-dir that contains files that are
+ hard-linked to their destination equivalents, rsync now makes sure
+ that removed files really get removed (works around a really weird
+ rename() behavior).
+
+ - Avoid a bogus run-time complaint about a lack of 64-bit integers when
+ int64 is defined as an off_t and it actually has 64-bits.
