Hi all, On January 21, we will be merging Firefox 66 from mozilla-central to beta for the first time. In order to avoid invalidating the testing we get out of late Nightly and the early Developer Edition builds and to ensure that we can roll out Beta 66 to a wider audience with confidence, we'd like to ask that any risky changes be avoided from January 21 until after the version bump to 67 on January 28. Please also be mindful of any landings late this week or over the weekend as there will be very little buffer between the first merge and shipping the 66.0b1 builds.
Some reminders for the soft code freeze period: Do: - Be ready to backout patches that cause crash spikes, new crashes, severe regressions - Monitor new regressions and escalate merge blockers - Support release management by prioritizing fixing of merge blockers Do Not: - Land a risky patch or a large patch - Land new features (that affects the current Nightly version) — be mindful that code behind NIGHTLY_BUILD or RELEASE_OR_BETA ifdefs can lead to unexpected CI results - Flip prefs that enable new Features that were untested in Nightly cycle - Plan to kick off new experiments that might impact a feature's merge readiness Please let us know if you have any questions/concerns. Thanks, Release Management Team -- ---- Liz Henry (:lizzard) Firefox Release Manager lhe...@mozilla.com _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
