- <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.
