-  - alpha transparency support
-  - truetype fonts
- 
-* additional graphics formats: EPS, PDF, SVG
-
-* extended multi-part documentation

-  maximum rate seen by rrdtool; compute and show the average
+##########################################
+Functional Changes between 1.3.x and 1.4.x
+------------------------------------------
 
-* Sliding window (trend) analysis
-  Compute a smoother average, for instance over the last 6 CDPs
+RRDcached Accelerator
+---------------------
+tbd
 
-* 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
+* no more spaces in output
+* additional option: --header {none,xsd,dtd}
 
-* the --alt-y-mrtg option is gone or rather since 1.2.7 it is back but
-  without functionality.
-
-* 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.
