+
+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+* libart has been replaced by cairo/pango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)

 Incompatibilities
