<release version="3.2" date="2013-04-03" description="
This is a minor release: It combines bug fixes and new features.
Changes to existing features were made in a backwards-compatible
way such as to allow drop-in replacement of the v3.1[.1] JAR file.
Most notable among the new features are: Framework for automatic
differentiation, Lévy distribution, prime numbers, discrete
distributions, real field allowing to use several algorithms
(solvers, linear algebra, 3D geometry) with different real-like
classes (high accuracy or automatic differentiation), spherical
coordinates with gradients and Hessians, reorganized clustering
package with different distances implementations.
The minimal version of the Java platform required to compile and use
Commons Math is Java 5.
Users are encouraged to upgrade to this version as this release not
only includes bug fixes but also deprecates numerous classes and
methods that will be deleted from the next major release (4.0).
Caveat:
1. The implementation of the BOBYQA optimization algorithm is in alpha
state (cf. MATH-621): Many code paths are untested, and we are looking
for volunteers to improve the code readability, robustness and performance
and to extend the unit tests suite.
2. A few methods in the FastMath class are in fact slower that their
counterpart in either Math or StrictMath (cf. MATH-740 and MATH-901).
