+    -   Per-file dynamic block size is now sqrt(file length).
+
+       The per-file checksum size is determined according
+       to an algorythm provided by Donovan Baarda which
+       reduces the probability of rsync algorithm
+       corrupting data and falling back using the whole md4

-    - Fixed a crash bug when interacting with older rsync versions and
+    -   for protocol version >= 27, mdfour_tail() is called when the
+       block size (including checksum_seed) is a multiple of 64.
+       Previously it was not called, giving the wrong MD4 checksum.
+       (Craig Barratt)
+  
+    -   for protocol version >= 27, a 64 bit bit counter is used in
+       mdfour.c as required by the RFC.  Previously only a 32 bit bit
+       counter was used, causing incorrect MD4 file checksums for
+       file sizes >= 512MB - 4.  (Craig Barratt)
