[math] Inserting 3.6 into changes history.
Repository: commons-math
Updated Branches:
refs/heads/master bd557f1b8 -> 7e1c299da
Inserting 3.6 into changes history.
The actions that were tagged in 4.0 as "backported in 3.6" because they
were present in both master and MATH_3_X branch have been removed from
the 4.0 specific changes as they already appear below in the 3.6
specific changes.

+ <release version="3.6" date="2016-01-05" 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:
+ 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).
