Full Changelog

Logins

What's changed

• The update() and add_or_update() methods will log rather than return an error when trying to update a duplicate login (#4648)

Logins, Places, SyncManager

What's Changed

• These packages all use parking_lot::Mutex instead of std::Mutex, meaning we should no
  longer see errors about mutexes being poisoned.

Push

What's fixed

• Fixes a bug where the subscriptions would fail because the server didn't return the uaid, this seems to happen only when the client sends request that include the uaid.(#4697)

General

• We now use xcode 13.1 to generate our iOS build artifacts. (#4692)
