Welcome back. As the podiatrist said, lots of exciting stuff is afoot.

Modernize infrastructure:

The big news from the past few weeks comes from the TaskCluster migration project where we now have nightly updates being served for both Linux and Android builds on the Date project branch. If you’re following along in treeherder, this is the equivalent of “tier 2” status. We’re currently working on polish bugs and a whole bunch of verification work before we attempt to elevate these new nightly builds to tier 1 status on the mozilla-central branch, effectively supplanting the buildbot-generated variants. We hope to achieve that goal before the end of 2017. Even tier 2 is a huge milestone here, so cheers to everyone on the team who has helped make this happen, chiefly Aki, Callek, Kim, Jordan, and Mihai.

A special shout-out to Dustin who helped organize the above migration work over the past few months but writing a custom dependency tracking tool. The code is here https://github.com/taskcluster/migration and you can see output here: http://migration.taskcluster.net/ It’s been super helpful!

Improve Release Pipeline:

Many improvements to Balrog were put into production this past week, including one from a new volunteer. Ben blogged about them in detail.

Aki released several scriptworker releases to stabilize polling and gpg homedir creation. scriptworker 1.0.0b1 enables chain of trust verification.

Aki added multi-signing-format capability to scriptworker and signingscript; this is live on the Date project branch.

Aki added a shared scriptworker puppet module, making it easier to add new instance types. https://bugzilla.mozilla.org/show_bug.cgi?id=1309293

Aki released dephash 0.3.0 with pip>=9.0.0 and hashin>=0.7.0 support.

Improve CI Pipeline:

Nick optimized our requests for AWS spot pricing, shaving several minutes off the runtime of the script which launches new instances in response to pending buildbot jobs.

Kim disabled Windows XP tests on trunk, and winxp talos on all branches (https://bugzilla.mozilla.org/show_bug.cgi?id=1310836 and https://bugzilla.mozilla.org/show_bug.cgi?id=1317716) Now Alin is rebalancing the Windows 8 pools so we can enable e10s testing on Windows 8 with the re-imaged XP machines. Recall that Windows XP is moving to the ESR branch with Firefox 52 which is currently on the Aurora/Developer Edition release branch.

Kim enabled Android x86 nightly builds on the Date project branch: https://bugzilla.mozilla.org/show_bug.cgi?id=1319546

Kim enabled SETA on the graphics projects branch to reduce wait times for test machines: https://bugzilla.mozilla.org/show_bug.cgi?id=1319490

Operational:

Rok has deployed the first service based on the new releng microservices architecture. You can find the new version of TryChooser here: https://mozilla-releng.net/trychooser/ More information about the services and framework itself can be found here: https://docs.mozilla-releng.net/

Release:

Firefox 50 has been released. We’re are currently in the beta cycle for Firefox 51, which will be extra long to avoid trying to push out a major version release during the busy holiday season. We are still on-deck to release a minor security release during this period. Everyone involved in the process applauds this decision.

See you next *mumble* *mumble*!
