Picard 3 beta 4 fixes startup issues on macOS

We have released Picard 3 beta 4. The recently released beta 3 did crash on macOS and when running the picard-plugins command line tool, both has been fixed in this. In addition beta 4 fixes display issues in the new log view.

Download links and a detailed list of changes since Picard 3 beta 3 are available below. For a more detailed overview of what is new in Picard 3 please see the previous blog post Picard 3 Alpha Release.

While we have all the major features implemented and with the latest bug fixes we are confident in the current code, this is still a pre-release and there might be bugs. If you use this, do so with care, backup your files and please report any issues you encounter.

Some of the changes are also backward incompatible, hence we recommend you make a backup of your Picard.ini config file before trying the beta version. You can do so in Picard’s Options under Advanced > Maintenance.

MusicBrainz database schema change release, 2026-05-11 (with upgrade instructions)

We’re happy to announce the release of our May 2026 database schema change now! Thanks to all who were patient during Monday’s downtime as we released everything to our production servers.

This is a fairly small database schema change release which mostly improves things behind the scenes. Of the schema change tickets, the only one that affects users directly is you are most likely to notice while you browse and edit in MusicBrainz is MBS-14092 (which allows adding series of series, for example for award series for podcasts).

Thanks to chaban, UltimateRiff and yyb987 for having reported bugs and suggested improvements, and thanks to jmrr83, salo.rock and wileyfoxyx for updating the translations.

A new release of MusicBrainz Docker is also available that matches this update of MusicBrainz Server. See the (amended) release notes for update instructions.

MusicBrainz Server update, 2026-04-27

This release mostly consists of a very substantial rewrite of the external links editor code, to make that section of our editors more efficient. While doing that we also fixed a few long-standing links editor bugs. While we kept this code in beta for quite a while so the community could help us catch most new bugs, do not hesitate to report any issues you might find.

A new release of MusicBrainz Docker is also available that matches this update of MusicBrainz Server. See the release notes for update instructions.

Thanks to rinsuki for having contributed to the code. Thanks to fabe56, HibiscusKazeneko and Lioncat6 for having reported bugs and suggested improvements.
