-NEW 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
-
-NEW 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-* libart has been replaced by cairo/pango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 in-memory graphing with rrd_graph_v (Evan Miller)
-* draw dashed lines in graphs (Thomas Gutzler)
-* new interface graphv which returns inforamation using the rrd_info
- interface (Tobi Oetiker and Mark Plaksin)
-
-NEW 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.
-
-* 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.
-
-Rewrites
---------
-* rrd_restore now uses libxml for parsing which makes things much more
- tolerant towards xml variations. The old code could mostly just parse the
- xml as it was output by rrdtool dump. See also: 'incompatibilities' at the
- top of this document. (by Florian octo Forster)
-
-* rrd_update rewritten to make it more modular. Fixed two longstanding
- HW bugs in the process (Evan Miller)
-
-Internationalization (Takao Fujiwara and Tobi Oetiker)
---------------------
-* The help output by rrdtool has been internationalized. There are no real
- translations included with rrdtool yet, contributions are welcome.
-* The internationalization will only be compiled if libintl and friends are
- available on your system. Use the configure option --disable-libintl if
- you want to disable this feature
-
-Misc
-----
-* ruby rrd_fetch will return step as a last property -- Mike Perham
-
-Locale Independent Numeric 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.

-RRDTOOL NEWS
-============
-Major Changes between 1.0.x and 1.2.x
-
-Graphing
---------
-
-* rewritten graphics generation based on libart.
- - anti-aliased output
- - alpha transparency support
- - truetype fonts
-
-* additional graphics formats: EPS, PDF, SVG
-
-* extended multi-part documentation
-
-* VDEF support; define and use variables. Find, and use, the
- maximum rate seen by rrdtool; compute and show the average
-
-* Sliding window (trend) analysis
- Compute a smoother average, for instance over the last 6 CDPs
-
-* percentile (95th or other)
- Remove peaks, 95 percent of all rates are at or below the
