Users of Commons Math 2.0-2 should recompile their code against the 3.0 JAR file and must adjust the import statements to use the appropriate org.apache.commons.math3 base package. Most of the compilation errors users will encounter after the switch will be due to moved or deleted classes/interfaces resulting from package reorganization. Caveat: 1.

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 inc lude 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.math3.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.</td></tr> -<tr class="b"> +<tr class="a"> <td><a href="#a2.1">2.1</a></td> <td>2010-04-02</td> <td>This is primarily a maintenance release, but it also includes new features and enhancements.

Users of Commons Math 1.0-1.2 should recompile their code against the 2.0 jar.
