Hi all, On October 15, we will be merging Firefox 64 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 64 to a wider audience with confidence, we'd like to ask that any risky changes be avoided from October 15 until after the version bump to 65 on October 22. Please also be mindful of any landings late this week or over the weekend: we're shortening the soft code freeze this cycle to reduce confusion and friction, but that means we don't have a buffer between the first merge and shipping the 64.0b1 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 _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
