 RRDTOOL NEWS
 ============
-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
+##########################################
+Functional Changes between 1.3.x and 1.4.x
+------------------------------------------
 
-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-* libart has been replaced by cairo/pango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.
-
-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.
-
-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
+RRDcached Accelerator
+---------------------
+tbd
 
-* 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
-  returned value
-
-Logging
+RRDdump
 -------
-* a second logging interface: rrdtool updatev
-  Verbose updating of the database; show CPDs being created
-
-* Aberrant Behavior Detection with Holt-Winters Forecasting
-  Compare current data with expected data, detect and log when
-  the rates are outside expected levels
-
-* COMPUTE data type for artificial data-sources calculating their
-  input using RPN math and data from the other data-sources.
- 
-Incompatibilities
------------------
-* Colons in COMMENT arguments to rrdtool graph must be escaped with a backslash
-
-* the --alt-y-mrtg option is gone or rather since 1.2.7 it is back but
-  without functionality.
+* no more spaces in output
+* additional option: --header {none,xsd,dtd}
 
-* In pipe mode, rrdtool answers with OK only if it was successful with the
-  command. Otherwhise the answer will be ERROR...
-
-
-Behind the Scenes
------------------
-* In order to support Holt-Winters and Calculated Datasources,
-  the rrdtool data format has changed. While the new version of rrdtool can
-  read files created with rrdtool 1.0.x. It is not possible to read files
-  created by rrdtool-1.2.x with rrdtool-1.0.x
-
-* External libraries are not included with rrdtool anymore. This is in line
-  with todays trend of using shared libraries everywhere. With the exception
-  of the cgi library most things required by rrdtool will be found on every recent
-  system.
-
-* Memory Mapped IO support for faster logging.
+RRDgraph
+--------
+* VDEF PERCENTNAN (PRECENT that ignores NAN)
