+RRdtool dump / restore Incompatibilities
+----------------------------------------
+rrdtool dump 1.3 does emit completely legal xml. Basically this means that
+it contains an xml header and a DOCTYPE definition. Unfortunately this
+causes older versions of rrdtool restore to be unhappy.
 
-File access methods (Bernhard Fischer)
+To restore a new dump with ann old rrdtool restore version, either remove
+the xml header and the doctype by hand (both on the first line of the dump)
+or use rrdtool dump --no-header.

+Rewrites
+--------
+* rrd_restore now uses libxml for parsing which makes things much more
