[ANNOUNCE] Apache Commons Math 3.6 released

[Luc Maisonobe <lu...@apache.org>]

The Apache Commons Team is pleased to announce the availability of
Apache Commons Math 3.6.

Apache 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 3.6 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: field-based version of
Ordinary Differential Equations framework, numerous improvements in
distributions, statistics and neuralnet packages, refactored
implementation of microsphere interpolation algorithm, explicit
specification of rotation convention to use (both vector operator and
frame transform conventions are now available). 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).

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).
