This release is NOT source and binary compatible with earlier versions
of Commons Math. Starting with version 2.0 of the library, the minimal
version of the Java platform required to compile and use commons-math
is Java 5. Switching to this new version is thought to be an easy task
and it is recommended to do it. Most of the compilation errors users
will encounter after the switch will be due to classes moved due to
packages reorganization. These errors are simply solved by adjusting
the import statements in users code. In any case, you can ask for help
by sending a message to the users mailing list: user@commons.apache.org.
