#MusicBrainzSchemaChange announcement for 2026-05-11

Schema-wise, this release will be very light. At the same time, we’ll be requiring some major dependency upgrades to Perl, PostgreSQL, and Node.js. We’ll also be switching from Redis to Valkey in production. See below for more information.

The only breaking *schema* change is MBS-14252. It drops columns which are unused even in MusicBrainz Server, so should have little impact.
