+Major Changes between 1.3.x and 1.4.x
+-------------------------------------
+
+RRD Caching Daemon (rrdcached)
+------------------------------
+by Florian Forster and Kevin Brintnall
+
+The RRD Caching Daemon can dramatically improve the 'update' performance
+of your system. Due to file handling overheads, the time it takes todo one
+update is virtually the same as to doing two updates in a row.
+
+The Cache Daemon intercepts rrdtool update calls, assembling multiple
+updates before writing them to the actual rrd file. When calling rrdtool
+graph in such a setup, the command will tell the daemon to flush out all
+pending updates for the rrd files, required to draw the graph.
+
+See rrdcached documentation.
+
+RRD Dumping and Restoring (rrdtool dump/restore)
+------------------------------------------------
+by Tobi Oetiker
+
+The output of rrdtool dump has been adjusted to be simpler to parse by
+existing xml parsers.
+
+The restore core has been completely re-written yet again and is now relying
+on an incremental xml parser. This has the advantage that the memory
+consumption while restoring xml files is only slightly larger than the
+resulting rrd file. Which is much less than the requirements of the 1.3 and
+even 1.2
+
+RRD Graphing functions (rrdtool graph)
+--------------------------------------
+by Martin Sperl
+
+* VDEF PERCENTNAN (a PRECENT that ignores NAN)
+
+* CDEF PREDICT and PREDICTSIGMA functions for on-the-fly
+ data prediction without the need to modify existing rrd files as it is
+ required for HoltWinters.
+
+* LibDBI integration provides a path to read data directly of a supported
+ SQL database into rrdtool graph. See rrdgraph_libdbi documentation.
