Maven 3.1.0 update
Most things are ready release-wise but I found a rather nasty performance regression. Seems to be two contributing factors: differing versions of Wagon seem to contribute to a large slow down and there appears to be some massive classloader leakage which is probably something I did recently. Running the ITs in embedded mode always reveals these problems and they show the following.
3.0.3
Tests run: 714, Failures: 4, Errors: 2, Skipped: 0, Time elapsed: 342.985 sec <<< FAILURE!
3.0.4 with Wagon 2.2
Tests run: 714, Failures: 4, Errors: 2, Skipped: 0, Time elapsed: 371.001 sec <<< FAILURE!
3.0.4 with Wagon 2.3
Tests run: 714, Failures: 4, Errors: 2, Skipped: 0, Time elapsed: 472.893 sec <<< FAILURE!
3.1.0 with Wagon 2.3
Tests run: 656, Failures: 13, Errors: 233, Skipped: 0, Time elapsed: 576.268 sec <<< FAILURE!
With trunk everything is tanking with permgen failures so I'm trying to track this down with Igor. So I would have like to have put 3.1.0 up for vote today but I'm going to track this down first and try and get the performance back to at least 3.0.3 levels. I'm also going to put the performance framework Igor developed back up on a machine.
Thanks,
Jason

Running from the command it's probably not the end of the world. But I always run this to make sure long-lived processes work and it generally finds any nasty stuff hiding because using the same Maven instance over and over doesn't last very long with anything leaking badly. Igor and I are getting the same results but I think it's a function of a couple things it seems. First we don't dispose of the plugin class realms and purge them like we do in m2e, and then I believe there are some plugins that are loading more things and just blowing the permgen. So we're trying to figure out how to purge the class realm cache. This will take care of the memory problem, and then I'll start looking at the speed.

as long as it's the same value for ant bootstrap build and mvn build

Not sure if it matter with the setup that's there, but that's say "3.0-SNAPSHOT" not "3.1-SNAPSHOT".
