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.

+<td>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 v3.3 JAR file. Most notable among the new features are: new distributions (Gumbel, Laplace, Logistic, Nakagami), and improvements on percentiles algorithms (better handling for NaNs in the regular algorithm, plus a new storeless implementation). Bicubic and tricubic interpolators have been fixed and new implementations added. There have been numerous bug fixes and several improvements on performances or robustness. See below for a full list. The minimum version of the Java platform required to compile and use Apache Commons Math is Java 5.
