+This is a major release: It combines bug fixes, new features and
+changes to existing features.
+
+Most notable among the new features are: XXX
+
+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.
+
+Because of the bas 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 due to 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
+counterparts in either Math or StrictMath (cf. MATH-740).
