MusicBrainz Server update, 2020-08-10

After a slow summer month, and hot on the heels of the release of Picard 2.4, an update for MusicBrainz Server has finally arrived, fixing ten bugs, converting almost as many templates to React, making small improvements and bringing a few handy new features.

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

Picard 2.4 released

The Picard team is happy to announce that version 2.4 of MusicBrainz Picard is now available for download. MusicBrainz Picard is the official tag editor for the MusicBrainz database and helps you get your music collection sorted and cleaned up with the latest data from MusicBrainz.

This releases brings significant performance improvements, improved documentation, new features and many bugfixes.

What’s new?

Better performance and responsiveness

Picard 2.4 features heavily improved performance and responsiveness of the user interface when loading or saving a large amount of files.

Improved online documentation

There is a completely new User Guide for MusicBrainz Picard, which replaces the documentation previously available on the Picard website. This documentation is much more complete and easier to update and maintain.

We are also looking for contributors who help to improve the documentation. If you have some ideas for improvements have a look at the Picard Docs project on GitHub.

Support for tagging WAVE and DSDIFF

Picard now finally supports writing tags to WAVE files. This was previously not possible, as there is lack of a proper standard to tagging WAVE files. Now Picard will allow you to write ID3v2 tags to WAVE files. As this is not supported by all players and tagging tools, Picard can optionally fall back to writing RIFF INFO tags to the files. Just be aware that RIFF INFO is very limited in regards to tags available and support for non latin character sets.

As a new file format Picard now supports DSDIFF (also known by their file extension as DFF) files. These can be loaded and saved using ID3v2. Similar to WAVE there is no standard way for tagging DSDIFF files, but many playback tools which support DSDIFF also support the ID3v2 tags.

Script auto completion and inline documentation

The script editors in the options dialogue (both for file naming and metadata scripts) now support auto completion for function and variable names. In addition there is a new script documentation dialogue, which shows the documentation for all scripting functions without the need to open the online documentation in your browser.

Dark mode support for Windows 10

On Windows 10 Picard now respects your settings for the Windows dark mode. If enabled, Picard will use a dark color theme and optimized syntax highlighting. This work also allows us to further improve Picard for dark themes on other platforms in the future.

Updated translations

With this release a lot of translatable text has been added to Picard, and many translations have been updated.

But not all translations are completed and we always need help maintaining the translations for Picard. Translating is easy and can be done online: Head over to MusicBrainz’s translation page on Transifex and click on “Help Translate MusicBrainz”. Any changes to the translations will be included in the next release.

More changes and bugfixes

Picard 2.4 has many more improvements and fixes. See the full changelog for details on all changes since the last stable Picard 2.3.2.


Picard 2.4 is available for download from the download page. For Windows 10 users installing from the Windows Store an update will come automatically as soon as the new release has been approved by Microsoft.


This release contains code changes by Gabriel Ferreira, Laurent Monin, Bob Swift, Philipp Wolfer, RaysDev, Wieland Hoffmann and new contributors Adam James, jcaesar and elvquant.

Special thanks go to Gabriel Ferreira for his excellent work in profiling and improving Picard performance and to Bob Swift, who completely overhauled Picard’s documentation, making it much more complete then it ever has been, and to all the translators who updated their language translations on Transifex.

MusicBrainz Server update, 2020-06-29

The React conversion is back with this release. We’ve also fixed a regression that listed unrelated “recording of” relationship edits in history of artists, recordings, and releases, and made a lot of people quite frustrated during the last two weeks (sorry about that!). New edits won’t be wrongly listed anymore, and the existing wrongly-listed edits will be progressively unlisted during the following days. Finally, two new data reports have been created, and small display improvements have been made.

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 loujin for contributing code. Thanks to DjSlash, hibiscuskazeneko, insolite, jesus2099, and mavit for having reported bugs and suggested improvements. Thanks to Atsushi Nakamura, kellnerd and salorock for updating the translations. And thanks to all others who tested the beta version!

MusicBrainz Server update, 2020-06-15

Today’s release focuses on stability with almost half of changes being bugfixes. It also provides a fair number of small improvements and new features. On a side note, the third party affiliated Magic Tagger is now known as AudioRanger.

MusicBrainz Server update, 2020-06-02

Now that PostgreSQL has been upgraded to version 12 (see earlier instructions), regular improvements, bugfixes, and React/JSX template refactoring are back on the menu. The most noticeable improvement is probably that we are now able to display more specific error messages in the URL relationship editor when a link is not allowed, instead of always giving a generic “not good”-style message. There are even new features, for admins only, that will allow them to spot and delete sock-puppets and to temporarily disable edit notes from editors who continue to be disrespectful to others without having to delete their accounts outright.

In news not directly connected to the MusicBrainz website, the public search endpoint has been moved from the old search server to the Solr-based search server. This can be used by slave servers if they do not need, or can not afford, to host their own search indexes.

And while talking about slave servers, a new release of MusicBrainz Docker is also available. It follows this update of MusicBrainz Server and fixes a regression that affects servers with live indexing. See the release notes for update instructions.

Thanks to Cyna for converting more edits’ display to React, to KamranMackey and navap for updating external links’ icons. Thanks to alastairp, BestSteve, chaban, chirlu, cyberskull, Freso, hibiscuskazeneko, jesus2099, and Kid Devine for having reported bugs and suggested improvements.

Picard 2.3.2 released

Picard 2.3.2 has been released and is available for download. This is mainly a bug-fix release with few minor improvements, see below for a full list of changes.

This release contains code changes by zas, rdswift, outsidecontext, RaysDev and new contributors Undearius and Gabrielcarvfer, who also is working on some interesting changes regarding UI responsiveness.
Thanks a lot to everybody who contributed to this release with code, translations, bug reports and general feedback.


Picard 2.3.2 is available for download from the download page.


Below is a list of all changes since Picard 2.3.1. If you are upgrading from an older version you might want to read previous release post.

Breaking change:

$find script function now returns “” rather than -1 on not found, for the sake of consistency. You may want to review your scripts.

Notable improvements:

Picard was trying to guess the file format based on file content. This was very IO expensive and in many cases not needed. So we decided to change the logic to:

  • Try guessing the format by file extension first
  • If no extension or no matching file extension is available, guess by file content
  • If format was guessed by extension and loading the file with mutagen fails with an exception, retry with guessing by file content. Retry loading if the newly guessed format is different from the format guessed by extension.

Also notable, On Windows 10, support for fractional scaling was implemented.

The complete list of changes is the following:


  • [PICARD-1775] – $firstwords function doesn’t catch IndexError
  • [PICARD-1776] – $datetime crashes when invalid format specified
  • [PICARD-1781] – Have $find return “” rather than “-1” on not found
  • [PICARD-1783] – Deleting performer, comment or lyrics tag fails for some cases in ID3, Vorbis, MP4 and Apev2 tags
  • [PICARD-1784] – Host not found error when downloading PDF artwork
  • [PICARD-1785] – $delete(_id3:TXXX:foo) does not delete the ID3 frames
  • [PICARD-1786] – Deleting tag stored in ID3 TIPL frame only removes first occurrence
  • [PICARD-1787] – Deleting case-insensitive TXXX frames does not delete anything
  • [PICARD-1788] – Saving ID3 tags marked as case-insensitive causes duplicated TXXX frames
  • [PICARD-1790] – Crash when selecting plugin that can be updated
  • [PICARD-1791] – Network access is disabled error under VPN service
  • [PICARD-1795] – iTunes tags not removable (reappear after being deleted)
  • [PICARD-1801] – List index out of range when saving Vorbis file
  • [PICARD-1803] – Instrument EWI is rewritten “e w i”


  • [PICARD-1777] – Support fractional scaling on Windows 10
  • [PICARD-1800] – Simplify Unicode ‘Bullet’ to ASCII ‘Hyphen-minus’
  • [PICARD-1809] – Optimize format detection logic

Reminder: Upgrading to PostgreSQL 12 on May 18, 2020

As we announced in February, in two weeks time (May 18, 2020) we’ll be upgrading our production database server to PostgreSQL v12 (from v9.5). At the same time, v12 will become the minimum supported version for MusicBrainz Server, so we ask that you upgrade afterwards as soon as possible! If you’re still unsure, a Q&A is below.

When do I need to upgrade my postgres by?

As soon as possible after May 18 if you’d like to keep your musicbrainz-server code up to date.

How do I perform the upgrade?

We’ll provide instructions closer to May 18. It’s recommended that you don’t upgrade until then, since we’ll be providing scripts to resolve some issues.

Will the live data feed (replication packets) stop working right away if I don’t upgrade?

No, as long as you keep your musicbrainz-server code checkout on the v-2020-05-11 tag (which will be the final release before May 18) or earlier. Future releases may work for a while too.

This is not a schema change release, so replication will continue to work smoothly until you upgrade. No tables or views will change.

However, to make the upgrade process smoother we’ll be dropping the musicbrainz-collate and musicbrainz-unaccent extensions, instead using PG’s builtin collation support for the former and replacing the latter with the unaccent extension from postgresql-contrib. A few SQL functions are being added to enable this, and some indexes need to be rebuilt. This will all happen as part of upgrade scripts we provide (or you can import from scratch). Some features of musicbrainz-server that use these old extensions may cease to work if you don’t apply them.

The extension changes above don’t actually make use of any new PG 12 features. We’ll avoid using such features for at least 1 month.

If I’m already running PostgreSQL 12, do I need to do anything?

Yes, but things will be easier for you. As mentioned in the previous answer, we’ll be dropping the musicbrainz-collate and musicbrainz-unaccent extensions to make the upgrade process smoother for pre-v12 instances. So you’ll only have to run some upgrade scripts we provide to replace those extensions and rebuild some indexes.

My host/distribution doesn’t have PostgreSQL 12 yet!

If you’re running Debian or Ubuntu, the PGDG maintains an APT repository with the latest versions. These are the same packages MetaBrainz uses in production.

Amazon RDS supports PostgreSQL 12 since March 31.

I absolutely cannot upgrade yet! What should I do?

You can stay on the v-2020-05-11 release of musicbrainz-server or earlier until then. Replication packets (i.e. the live data feed) will continue to work until the next schema change on that tag, but you’ll have upgraded to v12 by then, right?

Instead of performing a pg_upgrade and running these upgrade scripts you mentioned, can I just import fresh data dumps into a new v12 cluster?

Of course. Just make sure your musicbrainz-server git checkout is on the v-2020-05-18 tag (once that’s released) or later before performing the import. And keep in mind it may be slower than a direct upgrade.

MusicBrainz Server update, 2020-04-27

A large variety of issue types have been addressed in today’s release!

As a new feature, search indexes are now dumped and made available along with database dumps under the FTP directory search-indexes. They are mainly intended to be loaded on a MusicBrainz slave server to start a mirror with search.

Among improvements, a noticeable one is to lighten the area’s overview page that was heavily crowded with all sorts of relationships that have been scattered over more specific tabs.

As for bugfixes, the major one secures user/admin forms against CSRF attacks.

Thanks to atj for contributing code to support Traxsource URLs. Thanks to alex_s7, chaban, danbloo, Lotheric, murdos, Skeebadoo for reporting issues. Thanks to kellnerd, Jormangeud, mfmeulenbelt, salorock for updating the translations in German, Finnish, Dutch, Italian, respectively. And thanks to all others who tested the beta version!
