According to Jython's documentation:

  
Jython is an implementation of the
  Python language for the Java platform.
  Jython 2.5 implements the same
  language as CPython 2.5, and nearly
  all of the Core Python standard
  library modules. (CPython is the C
  implementation of the Python
  language.) Jython 2.5 uses the same
  regression test suite as CPython, with
  some minor modifications.

Are there any plans to support Python 3? If so, when is it scheduled to be released?
