v86.2.0 (2021-11-02)

Full Changelog

Push

What's Changed

- We've changed the database schema to avoid confusion about the state of subscriptions and
  in particular, avoid `SQL: UNIQUE constraint failed: push_record.channel_id` errors
  reported in [#4575](https://github.com/mozilla/application-services/issues/4575). This is
  technically a breaking change as a dictionary described in the UDL changed, but in practice,
  none of our consumers used it, so we are not declaring it as breaking in this context.

Logins

What's New

- Added support for recording telemetry when the logins encryption key needs to be regenerated.
