+This is primarily a maintenance release, but it also includes new features and
enhancements.
+
+ Users of version 2.1 are encouraged to upgrade to 2.2, as this release
includes some important bug fixes.
+
+ See the detailed list of changes below for full description of all bug fixes
and enhancements.
+
+ This release contains some minor compatibility breaks with version 2.1 in
some internal classes but none
+ of them are in APIs likely to be accessed by user code:
+ the MessagesResources_fr class has been removed (replaced by a properties
file);
+ the arguments of the EventState.reinitializeBegin method have changed;
+ some protected fields which already had public accessors in
AbstractStepInterpolator have been replaced.
+
+ There is a behavior change that users of the multiple regression classes
should be aware of. In version
+ 2.1, there was no way to estimate models without intercept terms, and, while
this was not clear from
+ the documentation, design (X) matrices needed to include initial unitary
columns. In 2.2, initial
+ unitary columns are not necessary and whether or not models include
intercept terms is configurable.
+ See the change log and javadoc for the classes in
org.apache.commons.math.stat.regression for details.
+
+ The major new features are:
+ a new FastMath class, both faster, more accurate and with a few additional
functions than StrictMath and Math;
+ a new package for floating point arbitrary precision computing, including
high level functions like exponential, sine, square root ...;
+ new linear and tricubic interpolators;
+ a new Gaussian curve fitter;
+ a new erfc function;
+ characteristic support for distributions;
+ a set of new Well Equidistributed Long-period Linear (WELL) random
generators.">
