+News for RRDtool 1.4
+====================
+$Id$
 
+RRD Caching Daemon (rrdcached)
+------------------------------
+by Florian Forster and Kevin Brintnall
 
-##########################################
-Functional Changes between 1.3.x and 1.4.x
-------------------------------------------
+The RRD Caching Daemon can dramatically improve the 'update' performance
+of your system.  Due to filehandling overheads, the time it takes todo one
+update is virtually the same as to doing two updates in a row.
 
-RRDcached Accelerator
+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.
+
+
+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
+consumtion while restoring xml files is only slighly larger than the
+resulting rrd file. Which is much less than the requirements of the 1.3.
+
+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.
+
+Miscellaneous Changes
 ---------------------
