-Graphing
+Graphing (Tobi Oetiker)
 --------
 * libart has been replaced by cairo/pango
 * pango markup is supported
-* full gridfitting
+* 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)
+* draw dashed lines in graphs (Thomas Gutzler)
+ 
+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.
+
+Misc
+----
+* ruby rrd_fetch will return step as a last property -- Mike Perham
+
+Incompatibility
+---------------
+* If you create an RRD with the new MHWPREDICT function, the resulting rrdfile will
+  be version 0004 and can only be used in rrdtool 1.3.
+
+Locale Independent Input
+------------------------
+* Regardles of locale you are in, rrdtool always expects input to be numbers (LC_NUMERIC)
+  in C or POSIX locale for numbers. (not 1,1 but 1.1) this is necessary to make
+  things like RPN work as it uses , as a separator.
