+Rewrites
+--------
+* rrd_restore now uses libxml for parsing which makes things much more
+ tolerant towards xml variations. The old code could mostly just parse the
+ xml as it was output by rrd_dump (by Florian octo Forster)
+
+* rrd_update rewritten to make it more modular. Fixed two longstanding
+ HW bugs in the process (Evan Miller)
+
+Misc
+----
+* ruby rrd_fetch will return step as a last property -- Mike Perham
+
+Incompatibility
+---------------
+* If you create an RRD with the new MHWPREDICT function, the resulting rrdfile will
+ be version 0004 and can only be used in rrdtool 1.3.
