+NEWS for rsync version 2.5.7
+Protocol: 27 (changed)
+Changes since version 2.5.6:
+
+  ENHANCEMENTS:
+
+    - Added --files-from, --no-relative, --no-implied-dirs, and --from0.
+      Note that --from0 affects the line-ending character for all the
+      --*-from options. (Wayne Davison)
+
+    -  Length of csum2 is now per-file starting with protocol verison
+       27. (J.W. Schultz)
+
+    -   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
+       checksums. (J.W. Schultz, Donovan Baarda)
+
+  BUG FIXES:
+
+    -   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)
+
+
+    - Fixed a crash bug when interacting with  Craiolder rsync versioss and
+      multiple files of the same name are destined for the same dir.
+      (Wayne Davison)
+
+    - Keep tmp names from overflowing MAXPATHLEN.
+
+  INTERNAL:
+
+    - Eliminated vestigial support for old versions that we stopped
+      supporting. (J.W. Schultz)
+
+    - Simplified some of the option-parsing code. (Wayne Davison)
