+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
+  returned value
+
+Logging
+-------
+* 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
+
+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.
