“Since the last update from around the time of 1.1alpha2, Thusnelda has moved to the SVN trunk where work has concentrated on final features, cleanup and testing for the Theora 1.1 (Thusnelda) final. We’re very close to the complete 1.1 and have already released two 1.1 release candidates. We’d optimistically scheduled final 1.1 release for last week, however we’re taken some additional time to do more testing/tuning of the two-pass rate control.”
A latest snapshot is available as part of Fedora 12 Alpha and in Rawhide for those who want to try it out
