* Implemented a new algorithm for hard-link handling that speeds
up the code significantly. (J.W. Schultz and Wayne Davison)
+ * The --hard-link option now uses the first existing file in the
+ group of linked files as the basis for the transfer. This
+ prevents the sub-optimal transfer of a file's data when a new
+ hardlink is added on the sending side and it sorts alphabetically
+ earlier in the list than the files that are already present on the
+ receiving side.
+
* Got rid of support for protocol versions 17 and 18 (which are
both over 6 years old). (Wayne Davison)
* More optimal data transmission for --checksum (protocol 28).
- * Less memory used for holding --checksum data.
+ * Less memory is used when --checksum is specified.
- * Less memory used per-file in the file list.
+ * Less memory is used in the file list (a per-file savings).
* The 2 pipes used between the receiver and generator processes
(which are forked on the same machine) were reduced to 1 pipe
