Release notes

• Breaking change: the meetings team feature flag is now disabled and locked by default. (#5292)

API changes

• cellsInternal in API version v17 now exposes storage quotas as totalLimitBytes and perUserQuotaBytes. totalLimitBytes is optional for backward compatibility with existing records, any negative value for either field is accepted as unlimited, and unlimited values are returned as -1. (#5271)

• • In API version v17 POST /register may now return a new 403 managed-by-scim error when a SCIM-managed pending user changes the display name during registration
  • The GET /teams/invitations/info?code=... response may now include the optional managed_by field (#5268)

• In API version v17, preventAdminlessGroups feature config updates should use
  duration string fields deletionTimeoutDuration and reminderTimeoutDurations.
  Feature config responses include both the new duration fields and the legacy
  day-based deletionTimeout and reminderTimeouts fields for backwards
  compatibility. API versions before v17 continue to accept the legacy
  day-based fields. (#5308)

• Added PUT /meetings/:domain/:id/invitations to replace the full list of invited emails of a meeting. (#5285)

• Added MeetingConversation as a new GroupConvType. Conversations can now be
  created with group_conv_type: "meeting". (#5296)

• Previously, POST /sso/get-by-email and GET /sso/initiate-login endpoints
  treated an IdP as globally configured for all domains when there was only one
  for a team. This led to information leakage and confusion. Now, these endpoints
  always treat IdPs as bound to a domain when multi-ingress is configured. I.e.
  IdP domain and request domain must match, otherwise an error is returned.

  To align with the others, this check is also added to the HEAD /sso/initiate-login
  pre-check endpoint. (#5291)

Features

• Prevent adminless groups (#5254, #5256, #5260)

• Changed the backgroundEffects team feature flag to be disabled by default (still unlocked). (#5269)

• Add idpCertFingerprintAllowlist configuration to restrict IdP certificates by
  fingerprint. This setting only changes the behaviour of wire-server if
  configured. So, no e.g. migration or action is required as long as this feature
  is not intended to be used. (#5272)

Bug fixes and other updates

• Do not allow changing the profile name during registration for SCIM users (#5268)

• Fix recurring meetings disappearing from GET /meetings/list (and
  GET/PUT/DELETE /meetings/{id}, the invitation endpoints, and the background
  cleanup worker) once the original time slot passed. Expiry and cleanup now
  account for recurrence.until; open-ended recurring meetings (no until) never
  auto-expire. (#5309)

• Bugfix: backgroundEffects feature flag was not configurable at the helm chart level. Now it is. (#5300)

• Fix MLS participant adds on meeting conversations by granting InviteAccess
  alongside PrivateAccess when creating the underlying conversation. Without
  InviteAccess, Galley rejects member joins after MLS commits with 403
  access-denied. (#5305)

• Fix CSP headers for SAML endpoints. These were falsely emitted for versioned SAML endpoints. (#5288)

Internal changes

• Fixed flaky cross-domain integration tests by pre-warming the static federation path (domain1 <-> domain2) once in test setup (#5312)

• Added logging on stale MLS commits in subconversations (#5251)

• Extend the conversation Code store to support meeting access codes in addition to conversation codes. Adds a backwards-compatible target column to the conversation_codes Postgres table (defaults to 'conv'); the Cassandra store continues to serve conversation codes only. Foundational work for meeting access codes. (#5281)

• Background worker now builds conversation subsystem config from the loaded Galley config and no longer fetches it over internal Galley RPC. (#5313)
