Picard 3 Release Candidate 4

We received good feedback on the previous release candidate 3, which resulted in several bugfixes and small improvements. The Picard team hence decided to release a fourth release candidate in preparation for the final release of Picard 3.0.

It fixes an important performance issue, so if you are currently running any of previous alpha, beta or release candidate versions upgrade ASAP.
It also fixes issues related to internationalization, causing some of existing translations to not actually show in the application (mainly constants).

Please test, test, and test, report any issue on forums, matrix, or, ideally, on the ticket system. When reporting an issue, always provide details about your environment and a full debug log helps us a lot. Also now is a good time for final review and improvements of the translations.

Download links and a detailed list of changes since Picard 3 release candidate 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.

If you are updating from Picard 2, note that some of the changes are backward incompatible, hence we recommend you make a backup of your Picard.ini config file before trying this version. You can do so in Picard’s Options under Advanced > Maintenance.

MusicBrainz Server update, 2026-09-21

Hi! It’s been a while since our last release since we have been working on stability improvements for both website and search to better cope with all the load we are handling recently. The first related changes are part of this release, with more to come, including limiting searches to 500 results (if you need something further down the search, sorry but you probably need a better search!). Additionally, the very annoying bug that sometimes lost track times when parsing tracklists should hopefully be gone now (thanks dvirtz!), and a lot more aggregator and shortener links are now blocked; even when not yet blocked, remember to always add all the relevant destination links rather than redirects and aggregators if possible.

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 derat, dvirtz, ibmibmibm and mib for having contributed to the code. Thanks to DenizC, derat, dvirtz, HibiscusKazeneko, j.rohr, outsidecontext, Raman Sinclair, rinsuki and salo.rock for having reported bugs and suggested improvements. Thanks to AligFu, AndrejsD1718, BestSteve, blueday, Covium, Denatura, EmO686, Flavia Telcean, joao_over9k, Kolesteraw, Life4649, liilliil, mfmeulenbelt, naturbrilian, NorwayFun, Priit Jõerüüt, pXF, syntariavoxmortem, TheParaziT, Vaclovas Intas, vacuousVersifier and wileyfoxyx for updating the translations. And thanks to all others who tested the beta version!

The git tag is v-2026-09-21.0.

Picard 3 Release Candidate 3

Please test, test, and test, report any issue on forums, matrix, or, ideally, on the ticket system.

When reporting an issue, always provide details about your environment and a full debug log helps us a lot.
Also that’s (always) a good time to review and improve translations.

The super special (lousy) shirt plan

Editors are by far MetaBrainz’ biggest and most irreplaceable resource.

They (you) spend countless hours entering data for free, be it for the love of music, to tidy their own collections and listen histories, to support their scenes, to archive historical and cultural data, to apply the cool and soothing editing brain-balm, or a combination of all of the above and more.

Some of the top editors have provided the backbone of MusicBrainz for years, decades, and often perform the more tedious data maintenance and checking tasks.

A few summits ago, the question was asked – can we give these editors, say those with 1 million+ edits, some recognition without getting into the quagmire of things like gamifying?

Enter super special (lousy) shirt plan.

reo showcasing his super special lousy shirt – a *real* and rare image of a top MusicBrainz editor **outside**!?

Picard 3 Release Candidate 1

The Picard team is excited to announce the first release candidate for Picard 3. With this release we are confident that Picard 3 is now suitable for testing by a wider audience. The final 3.0 release is planned to happen in a few weeks.

Since we are near a final release, we tried to focus on bugfixes, final changes to the Plugin API and further UI/UX improvements. On the UI side, Picard now fully supports dark / light mode across all supported operating systems, with the ability to change the theme without a restart.

Search upgrades: Nov 30, 2026

MusicBrainz is announcing a set of upgrades for its search service on November 30, 2026. The main change will be upgrading Solr from version 9 to 10. Fixes and improvements will be released alongside this. Some of these changes may break some specific search requests. Finally, a new feature will be released making it possible to use the search service to search for (musical) genres. See below for more information.

Breaking changes

The following tickets may break search requests in some way.

SEARCH-444: Improper ‘relation-list’ in ‘area’ and ‘url’ JSON output. This will be a breaking change for accessing related entities in area and URL search results.
SEARCH-642: Drop ‘id’ fields for cdstub and tag. This will technically be a breaking change, but it was broken by design as the values for these search fields are not documented and have never been intended for public use anyway.
SEARCH-666: Use quality names rather than numeric IDs. This will be a breaking change for release searches that use quality search field.
SEARCH-752: Relationships have an extra ‘target’ property in JSON output. Fixing it by removing the redundant property target will be a breaking change if you are accessing it in search results. The “proper” way to do this is to use the property target-type and access the property id under the property named after this target type.
SEARCH-764: Upgrade to Solr 10. This will be a breaking change for mirror owners only, not for search requests. More specifically, it is advised to change the Solr configuration and to re-index the whole MusicBrainz database.

Soft changes

The following tickets will improve search with breaking any requests:

SEARCH-452: Index all URL relationships. So far, only URL relationships to Artist and Release were indexed. URL relationships to all other entity types will be indexed too.
SEARCH-646: Return exact match first for tag search. It should improve tag search results using indexed Solr search compared to direct Postgres search.
SEARCH-677: Include disambiguation of event’s place and work’s recording. Places related to searched events and recordings related to searched works will now be outputted with disambiguation comment, in the same way other related entities are outputted in search results.
SEARCH-680: Index genre annotations. It will add genre annotations to the results of annotation search which is already supported for all other annotation-able entity types.
SEARCH-681: Support indexed search of genres. It will add “Genre” as a target type for search, just like most other searchable entity types.
SEARCH-751: Missing ‘target-type’ property in ‘relationships’ of ‘event’ and ‘work’ JSON output. This will be fixed by adding the property where it is missing.
SEARCH-753: Missing ‘target-type’ property in ‘relationships’ of ‘area’ and ‘url’ JSON output. This will be fixed by adding the property where it is missing.

Miscellaneous

A MusicBrainz Server release is also expected to go with some of these changes.

We’ll post upgrade instructions for standalone/mirror servers on the day of the release. If you have any questions, feel free to comment below or on the relevant above-linked tickets.

GSoC 2026: Development of a new Calibre plugin for BookBrainz

Hello, Everyone!

I am Md Waqib Sk (waqib2992 on IRC), an undergraduate student at Indian Institute of Technology Kharagpur. This summer, I had the opportunity to participate in Google Summer of Code 2026 with MetaBrainz, where I worked on developing a calibre plugin for BookBrainz.

I was mentored by Nicolas Pelletier (monkey on IRC). This post summarizes my project, its outcomes, and my experience over the course of the program.

Project Overview

Calibre is a free, open-source e-book manager used to organize and read digital books. My project was about introducing a new plugin that connected calibre with BookBrainz.

The main proposed features of the plugin were:

1. Metadata update: Search selected book from calibre in BookBrainz database and update it’s metadata accordingly.

2. Browse BookBrainz: Search editions/public collections by name/bbid through the plugin and add or download the corresponding metadata.

GSoC 2026: Bringing Internationalization (i18n) to BookBrainz

Introduction

Greetings, everyone!

I am Garv Thakre (@garvthakre:matrix.org on Matrix), an Agentic-AI FullStack Developer . This summer, I had the opportunity to participate in Google Summer of Code 2026 with MetaBrainz, where I worked on the internationalization (i18n) for BookBrainz.

I was mentored by Nicolas Pelletier (@monkey:chatbrainz.org on Matrix). This post summarizes my project, its outcomes, and my experience over the course of the program.

Project Overview

BookBrainz aims to collect information about every book ever written, but until now, the interface was only in English. Since books exist in thousands of languages, having an English-only UI made it tough for non-English contributors to navigate, read, or add metadata.

My main goal this summer was to get BookBrainz ready for translation and set up the foundation so the community can actually start localizing it. Here is what that involved:
