• birch as b2g-inbound has been great success. Official "b2g-inbound" branch is coming, soon "birch" will revert to being normal twig again. Details in bug 875989 or ask hwine.
• "integration/fx-team" will get sheriff coverage, landing to mozilla-central. We will monitor this experiment for next few weeks.
  • If you are on fx-team, please land on "fx-team" instead of "mozilla-inbound" unless directed otherwise by sheriffs.
• Try-repo-reset last week to address performance problems. If you see delays while pushing to try, please let sheriffs or RelEng know (or file a bug!)
• Talos-on-mozharness change coming tomorrow (Wednesday 24th). Details here: https://groups.google.com/forum/#!topic/mozilla.dev.tree-management/HRWB05plBnI

Quality Programs

MemShrink (njn)

Luke Wagner reworked asm.js parsing. The parsing memory peak in the Unreal demo has dropped from 800+ MiB to less than 10 MiB; parsing is a bit faster, too.

Justin Lebar and others have been making ongoing progress on fixing slow leaks in B2G. This is *extremely* important work.

• New meeting rooms for this meeting (lmandel)
  • SFO Warfield
  • TOR Finch
  • PDX Widmer
