+Major Changes between 1.3.x and 1.4.x
+-------------------------------------
+$Id$
+
+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.
+
+Miscellaneous Changes
+---------------------
+* graph legends can now be placed left, right or above the graph with the
+  new --legend-direction and --legend-positon placement options. 
+  by Melchior Rabe
+
+* switched to using automake 1.11 which provides a 'silent' build process,
+  causing errors and warnings to stand out much more than before.
+  by Tobi Oetiker
+
+* switched from intltoolize to autopoint for the i18n configuration.
+  by Tobi Oetiker
+
+* new graph option --grid-dash on:off to configure the dash length
+  in the grid painted over the graph by Tobi Oetiker
+
+* lua bindings for rrdtool
+  by Fidelis Assis
+
+* various improvements to rrd_open functions and mmap handling
+  by Daniel Pocock
+
+* allow the HW smoothing window size to be set to 0 with rrdtool tune
+  by sylvain luiset
+
+* new graph option --border to set the 3d border width 
+  by Bernhard Reutner-Fischer
+
+* draw different color swats depending on the type of line drawn in the
+  graph by Loïc Tortay
+
+for more detail see the CHANGES file.
