What's New

• Rollouts: allows winning branch promotion and targeting rollouts of features. #4567.
  • for both Android and iOS.

What's fixed

• Fixed a bug in iOS where the installation date would be set to start of EPOCH (#4597)
• Fixed a bug in Android where we were missing disqualification events after a global opt-out (#4606)

Push

• We've changed how the push database is opened, which should mean we now automatically handle
  some kinds of database corruption.

General

What's changed

• The bundled version of Glean has been updated to v42.0.1.
  See the Glean Changelog for full details.
  (Note there is a breaking change in Rust, but that doesn't impact consumers of Application Services)

@grigoryk @csadilek , we missed it in the changelog - but this has a useful change related to the recent logins work, removing many (some? not sure about the severity) logs from sentry that shouldn't have been a sentry errors, ref: mozilla/application-services@73b922e
(cc: @bendk)

We probably want to get this in before the end of the cycle to prevent the logs from crowding sentry

As per the discussion in slack, I opened #11192 that includes only the logins changes, this PR can wait till next cycle

We released 86.2.0, so updated this PR to update to that instead! In addition to the changelog above, the changelog for 86.2.0:

v86.2.0 (2021-11-02)

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. 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.

Tested this new version with Fenix, looks good to me 👍

[eliserichards]

I'm confirming with the rest of the team before we merge this @tarikeshaq

[jonalmeida]

I tested a fresh and existing install with push, and I did not come across any bugs. I actually think this solved a push bug with web content push too!

r+ and let's land it!
