This release should be deployed straight after 5.30. Please also consult the release notes for 5.31 for more changes.

Release notes

• • postgresMigration now has a single source of truth in the Galley chart values. Galley, Brig, and background-worker all read their PostgreSQL migration settings from there.
• If your deployment overrides the full postgresMigration object, add the new domainRegistration field to that override. Otherwise services may fail to start because the config is incomplete.
• To migrate domain registration data to PostgreSQL, set postgresMigration.domainRegistration to migration-to-postgresql, run the background-worker migration with migrateDomainRegistration: true, and switch the setting to postgresql after completion.
• The domain registration migration covers these Cassandra tables: domain_registration, domain_registration_by_team, and domain_registration_challenge. (#5195)

API changes

• Discontinue redundant end-point for fetching user clients. (#5222)

Documentation

• Improve swagger API docs. (#5220)

Internal changes

• New wire-ingress Helm chart — Gateway API / Envoy Gateway replacement for nginx-ingress-services. Not yet production-ready. (#5150)
