The Apache Commons team is pleased to announce the release of version 
2.0 of Commons Math.  Commons Math is a library of lightweight, 
self-contained mathematics and statistics components addressing the most 
common problems not available in the Java programming language or 
Commons Lang.

Version 2.0 is a major release, including bug fixes, new features and 
enhancements to existing features.  Most notable among the new features 
are matrix decomposition algorithms, sparse matrices and vectors, 
genetic algorithms, new optimization algorithms, curve fitting 
algorithms,  state derivatives in ODE step handlers,  new multistep 
integrators,  multiple regression, correlation, rank transformations and 
Mersenne twister pseudo random number generator.

This release is NOT source and binary compatible with earlier versions 
of Commons Math.  Starting with version 2.0 of the  library, the minimal 
version of the Java platform required to compile and use commons-math is 
Java 5. 

Source and binary distributions are available for download from the 
Apache Commons Math download site:

Please verify signatures using the KEYS file available at the above 
location when downloading the release.

Maven users please note that the maven repository groupId for Commons 
Math has changed in version 2.0 to "org.apache.commons."  The artifactId 
remains "commons-math."
