We’re very close to a 0.4.2 release… If you’re feeling brave and know your way around svn code, we invite you to try out the soon to be released 0.4.2 version.
You can check out pre-release branch here:
Please see “Pre-release Notes” in the README for some important information about using the svn version.
We’re putting on the finishing touches, so updates should continue over the next few days (hours?). If you do try it out & have any problems please let us know in #mumbles (freenode), or on the forum.
