 This file contains the release notes since Jikes RVM 2.0.0, released
 on October 14, 2001,
 
-* Jikes RVM 3.0.2  (Future)
+* Jikes RVM 3.1.0  (June 10, 2009)
 
-NOTE:  Release notes are generated directly from JIRA.
-If you want something mentioned in the release notes, make sure there is
-a JIRA item for it that when it is closed, you make it as fixed for 3.0.2.
+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.
