Jikes RVM version 3.1.0 has been released and is available for download at http://downloads.sourceforge.net/jikesrvm/jikesrvm-3.1.0.tar.bz2

It's been almost nine months since the release of Jikes RVM 3.0.1, and quite a bit has changed in Jikes RVM. We'd like to call out several items that may be of particular interest to the community.

  1. Jikes RVM has switched to using native threading instead of m-to-n (aka green) threading.
  2. The default mature space collector has changed from Mark-Sweep to Immix.
  3. Jikes RVM is now licensed under the Eclipse Public License (EPL).
  4. The 3.1 release significantly improves over the performance of 3.0.1, with speedups of 10% and 21% on average for DaCapo and SPEC benchmarks respectively on an Intel C2Q. Highlights include a 29% improvement in jbb and a 32% improvement in jython.

Details are given below, or are browsable online in our JIRA instance at http://jira.codehaus.org/browse/RVM/fixforversion/14620.
