QE

[Cornel]

• e10s multi testing [1393638] completed [Fx 55] - GREEN
  • report: https://goo.gl/hJx1cN

Nightly

[Adrian]

• QA Photon work on all areas: status @ https://docs.google.com/spreadsheets/d/1ERWXWhTDgPi15py-rCLuYGO5kgp6MtrocxvSATjMIEE/edit#gid=0
• QA Photon: waiting for the TP sign-offs and preparing for the pre-Beta test runs and pre-Beta sign off

Beta

[Cornel]

• 56.0b9 signed off without any issues
• 64-bit migration testing completed on "beta-cdntest", "aurora-cdntest", "aurora" and "beta" - GREEN
• Pre-release sign-offs are currently underway (due Sep 8)

[Bogdan] [Photon Preferences Search] We are concerned about this feature since there still are several new bugs that affect both the usability and design of the feature. We are inclined not to let this feature reach 56 release only after fixing the newly found issues. Here is a list with all the new bugs that need fixing: https://goo.gl/GkQoRm [Julia]

• DevTools GoFaster - Per engineering, the feature is missing 57 due to blockers on the add-on startup code and the stabilization issues (see https://goo.gl/umcTfC )

Mobile

[Ninu]

• Tuesday - Signed off the 56.0b9 build with no major issues
• Today - Signed off the Nightly Pre-check part 2 session with no major issues

Roundtable

• [julien] some users get 3 watersheds on 56.0bX, do we want/need to avoid that?

beta 3 - signing/compression beta 8 - to get the mig64 flag 64-bit - beta 9 to be migrated to 64-bits

• can we repackage beta 8 signing?
  • required for 56.0 RCs https://bugzilla.mozilla.org/show_bug.cgi?id=1393789
  • no QA resource available to test that

• did we turn automated update tests back on? - liz will follow up with florin
  • planned for next week

System Add-ons

[Adrian] - not sure where this item should go

• Shield Opt-Out - QA mostly done, waiting for two fixes to land so we can smoke test it and sign it off
