Performance (Thu)

Aurora / Dev Edition

Beta

Release

QE

• [Florin] I'll be on vacation between Nov 1st and Nov 10th (back in office on the 11th) - people to contact:
  • Desktop - Andrei Vaida and Cornel Ionce
  • Mobile - Ioana Chiorean
  • Ondemand Update tests - Andrei Vaida, Rail Aliiev, Mihai Tabara

Nightly

[Andrei]

• New features picked up: Skia Content for Windows (1186552), Downloads Panel (950058, 1289139).
• First-party-isolation (1299996) is also planned to ride Fx52 -- we're syncing there with Kamil.

Aurora / Dev Edition

[Andrei]

• Mid-Aurora feature sign offs completed.
• Testing on layout.show_previous_page telemetry experiment has been completed, we're currently following up with Dominik on a few potential issues (nothing blocking).
• The once-per-cycle WebRTC sign off is currently underway -- should be done tomorrow.
• Aurora Testday planned for tomorrow, focused on new features, see: http://tinyurl.com/zauaj4w.

Beta

[Andrei]

• Pre-Release feature sign offs are underway, everything green so far. Simplify Page (962433) will not go through this process, since its milestone has already been changed to Fx51.
• Testing on Sign-in Unblock, Device Manager and Apps/Service Manager has been completed, no blockers identified.
• New feature found at the last minute: Directory Uploading (1188880). We won't be able to sign it off properly at this point, but regression testing is already in progress for it, see: http://tinyurl.com/z2b2hlk.

Action items

Mobile

[Mihai Ninu] We signed off the Beta 10 last Tuesday with no major issues. [Mihai Ninu] As discussed last week, the HLS feature is under discussion if it should be released or not with this beta, no decision taken yet. QE proposes it should be kept under Aurora flag until some of the major issues are fixed. [Mihai Pop]

• Yesterday I've had the Kickoff Meeting with the Taipei team for the Presentation API feature - Bug 1184036 - meta bug
• It's set to Target Milestone 52, but has not landed yet in Nightly
• I would recommend to postpone this at least to Firefox 53, since Nightly 52 will merge to Aurora next week
• Bug 1313368 - [Presentation API] Fennec stalls when trying to load a page - critical bug
  • This could be something we can include in the Nightly52 -> Aurora52 merge criteria
