Release Engineering

A brief look at RelEng since Whistler

It's really great to see you all here. One of the things I really love about these weeks together is that chance to spend time with you in person. We always finish these weeks with great ideas to chew on in the coming months.

Our Team

Welcome Vlad, Alin!

Welcome (back!) Mihai!

If you haven't met Vlad, Alin, please introduce yourself. They have made a HUGE impact on our team since joining us this summer.

Releases

  • July 2nd - Shipped Firefox 39
  • 8 releases shipped since then...
  • including 5 point releases...
  • and our big "moment in time" release, Firefox 42
  • We also turned on Funsize in production for Nightly / Aurora builds!
One of our main areas continues to be releases. Since Whistler, we've had quite a few...exciting releases. Our big moment-in-time release, Firefox 42, introduced great features like new developer tools, tracking protection and this morning we've seen the impact this release and user campaign has had.

FxOS moment-in-time release (2.5)

Heroic efforts by many to pull this together

We relied on team work and great tools to support new products like B2GDroid

Some big last-minute asks. Lots of hard work, late nights, but we got it done. A big thank-you to everybody involved for this.

Release build promotion

Streamlining our release pipeline to ship the CI builds we've already built and tested

Great progress this quarter on release build promotion. We have nearly all our binary deliverables created. Scheduling in TC, using BBB to drive jobs in buildbot. bouncer, update verify and final verify are working (?)
