Hi all,
With Firefox 80 release candidates already shipping, we are nearing the
end of the Nightly 81 cycle.
In order to avoid invalidating the testing we get out of late Nightly
and to ensure that we can roll out 81 Betas to a wider audience with
confidence, we'd like to ask that any risky changes be avoided from
Thursday August 20 until after the version bump to 82 on August 24.
Some reminders for the soft code freeze period:
Do:
- Be ready to back out 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 affect 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 the 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,
Sebastian & the Release Management team
