Release notes

• User search provides information about user type (regular, app, legacy bot) now. Also, Elasticsearch re-indexing requires postgres access now. If you run brig-index directly anywhere, make sure to add the relevant settings. The Elasticsearch index must be refilled from Cassandra in order for the changes to the search results to take effect. See https://docs.wire.com/latest/developer/reference/elastic-search.html?h=index#refill-es-documents-from-cassandra (#4913, #4957)

• Conversation codes can now be migrated to PostgreSQL. For existing installations:

  • Set postgresMigration.conversationCodes: migration-to-postgresql in both galley and background-worker.
  • Run the backfill with migrateConversationCodes: true.
  • Wait for wire_conv_codes_migration_finished to reach 1.0.
  • Switch to postgresMigration.conversationCodes: postgresql and disable migrateConversationCodes. (#4961)

• The background-worker defaults for the postgres migration now match galley and point to cassandra (previously postgres). This currenlty only affects the background job, which is not expected to run before postgres is in use. However, if you relied on the defaults after migrating to postgres, please update your config to keep using postgres. (#4965)

• Drop support for kubernetes versions below 1.27 (#4969)

API changes

• New end-point GET /teams/:tid/apps listing all team apps. (#4960)

• Add type field to search results received from GET /search/contacts (#4913)

Features

• nginx-ingress-services: Add federator.tls.issuer option to use a separate ClusterIssuer for federation mTLS certificates. (#4964)

• Log changes to IdP configurations made via the IdP REST API to syslog. (#4935)

• Allow commit bundles to contain one application message. The message must be for the epoch after the commit, and it gets sent after the commit has been accepted. (#4929)

Bug fixes and other updates

• background-worker's default settings for postgresMigration have been correctly set to cassandra. (#4965)

Internal changes

• Circumvent potential performance issue with TVar (Map ...) (#4948)

• Migration of conversation codes from cassandra to postgres (#4959, #4961)

• • Test for team and user email templates added
  • Refactoring to make email rendering testable
  • Removed SMS and call templates (#4699)

• Drop cryptobox, handle prekey in pure Haskell. (#4719)

• Move Feature Flags read to wire-subsystems. (#4918, #4974)

• Federator: Replace Linux-only hinotify with cross-platform fsnotify library
  for certificate file monitoring. This enables native file system watching
  on both Linux and macOS, removing the need for platform-specific stubs. (#4955)

• Simplify and modernize the Nix setup of rusty-jwt-tools. This includes
  updating to version 0.14.0. (#4952)
