“My update requests have your blood on them.”

This is release candidate week, traditionally one of the busiest times for releng. Your patience is appreciated.

Improve Release Pipeline:

Varun began work on improving Balrog’s backend to make multifile responses (such as GMP) easier to understand and configure. Historically it has been hard for releng to enlist much help from the community due to the access restrictions inherent in our systems. Kudos to Ben for finding suitable community projects in the Balrog space, and then more importantly, finding the time to mentor Varun and others through the work.

Improve CI Pipeline:

With build promotion well underway for the upcoming Firefox 46 release, releng is switching gears and jumping into the TaskCluster migration with both feet. Kim and Mihai will be working full-time on migration efforts, and many others within releng have smaller roles. There is still a lot of work to do just to migrate all existing Linux workloads into TaskCluster, and that will be our focus for the next 3 months.

Release:

We started doing the uplifts for the Firefox 46 release cycle late last week. Release candidates builds should be starting soon. As mentioned above, this is the first non-beta release of Firefox to use the new build promotion process.

Last week, we shipped Firefox and Fennec 45.0.2 and 46.0b10, Firefox 45.0.2esr and Thunderbird 45.0. For further details, check out the release notes here:
