The next update of the MusicBrainz server will happen on May 24th. For this update we will have the following new features:
- Release groups: Group together like releases (same titled releases by the same artist) into one group.
- Support for attaching ISRC codes to tracks.
- Bug fixes.
No later than this weekend I will post a call for testing with details on what has changed and what bugs were fixed. Stay tuned!
