+
+ Apache Commons Math 3.0 RELEASE NOTES
+
+The Commons Math team is pleased to announce the release of
commons-math3-3.0-SNAPSHOT
The Math project is a library of lightweight, self-contained mathematics and
statistics components addressing the most common practical problems not
immediately available in the Java programming language or commons-lang.
+This is a major release: It combines bug fixes, new features and changes to
existing features.
+Most notable among the new features are: Iterative solvers, Kalman filter,
ISAAC RNG, Illinois and Pegasus root finders, enhanced ODE framework,
refactored geometry package, Binary Space Partition trees.
+Most notable among the changes are: Exclusive use of unchecked exceptions,
removal of interfaces for which a single implementation is assumed to exist,
improved coding and API consistency across packages, performance (matrix
product, FFT) and robustness (SVD).
+Because of the base package name change, this release can be used together
with earlier versions of Commons Math. The minimal version of the Java platform
required to compile and use Commons Math is Java 5. Users are encouraged to
upgrade to this version as, in addition to new features, this release includes
numerous bug fixes. Users of Commons Math 2.0-2 should recompile their code
against the 3.0 JAR file and must adjust the import statements to use the
appropriate org.apache.commons.math3 base package. Most of the compilation
errors users will encounter after the switch will be due to moved or deleted
classes/interfaces resulting from package reorganization.
+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).
+

interpolation model
of the starter integrator inside only one step was wrong. The model
may have a too
low order to compute high degrees derivatives in the Nordsieck vector.
Now we use several
steps and use only grid points instead of interpolated points.
