 ============
+Major Changes between 1.2.x and 1.3.x
+
+see http://oss.oetiker.ch/rrdtool-trac/wiki/RRDtool13
+for up to date information
+
+File access methods (Bernhard Fischer)
+-------------------
+* introduced file-accessor functions rrd_read/rrd_seek/rrd_write
+* implemented full mmap-based file access with madvise hints for improved
+  scalability, much reduced memory-footprint and much less blocking on
+  disk
+* implemented optional full file-descriptor access instead of FILE* access
+
+Graphing (Tobi Oetiker)
+--------
+* libart has been replaced by cairo/pango
+* pango markup is supported
+* full gridfitting 
+* --graph-render-mode=mono for non antialiased graphing
+* --font-render-mode=mono for non antialiased fonts
+* fonts come through fontconfig, use the Pango fontnameing
+  scheme -> 'Times 20' ... it is not possible to use
+  truetype fonts directly anymore.
+* Tabs are position independent.
+* TRENDNAN filter that ignores NAN values while caculating the TREND data. (Timo Stripf)
+* --full-size-mode to specify the outer border of the image and not just of the graphing canvas (Matthew Chambers)
+* TEXTALIGN command to alter default text alignment behaviour
+* C API supports in-memory graphing with rrd_graph_in_memory (Evan Miller)
+ 
+Forecasting (Evan Miller)
+-----------
+* the new MHWPREDICT consolidation function uses a variation of the Holt-Winters
+  method. It is a drop-in replacement for HWPREDICT, and is better suited for
+  data whose seasonal variations grow or shrink in proportion to the average.
