EdX has set a target date for Birch’s official release: Tuesday, February 24.
David Baumgold, the edX engineer in charge, noted that “if a significant number of changes are added to the release candidate branch, a new release candidate will be created and the release date will be pushed back, to give people time to test the new release candidate”.
The “Birch” version is now on its RC3 (Release Candidate) phase. Bugs will continue to be fixed until the target date.
