- - Added two config items to the rsyncd.conf parsing: "pre-xfer exec"
- and "post-xfer exec". These allow a command to be specified on a
- per-module basis that will be run before and/or after a daemon-mode
- transfer.
+ - The --hard-link option now uses less memory on both the sending and
+ receiving side for all protocol versions. For protocol 30, the use
+ of a hashtable on the sending side allows us to more efficiently
+ convey to the receiver what files are linked together. This reduces
+ the amount of data sent over the socket by a considerable margin, and
+ moves the in-memory storage of the device+inode information from the
+ receiving side (for protocols < 30) to the sending side (note that
+ older rsync versions kept the device+inode information on both
+ sides).
