<release version="3.3" date="TBD" description="TBD">
<release version="3.3" date="2014-05-05" 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.x JAR file.
Most notable among the new features are:
Framework for creating artifical neural nets, self organizing feature maps,
computational geometry algorithms (convex hull, enclosing ball), performance
improvements of the linear simplex solver, refactoring of curve fitters,
low-discrepancy random generators (sobol, halton), least-squares fitting.
The minimum 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).
3. A few methods/constructors in the package o.a.c.m.geometry.partitioning
have changed their signature in a non backwards-compatible way. The respective
classes are intended to be package private only and are not supposed to be
used for other purposes.

<action dev="luc" type="fix" issue="MATH-1115">
Build properly empty polyhedrons set when given equal min/max boundaries. Also explained
better in the javadoc about some wrong usage of PolyhedronsSet constructor.
