Soft code freeze for Firefox 110 starts on January 12 @ 8am UTC
Pascal Chevrel
Hello,
With Firefox 109 in the Release Candidate phase this week, we are
nearing the end of the Nightly 110 cycle.
In order to avoid invalidating the testing we get out of late
Nightly and to ensure that we can roll out Beta 110 to a wider
audience with confidence next week, we'd like to ask that any
risky changes be avoided from Thursday, January 12 until after the
version bump to 111 on January 16.
Also, please be advised that string freeze for Firefox 110 begins
Friday, January 13. In order to ensure that our localizers have
adequate time to translate strings, please make sure that all
string changes have landed by EOD Friday.
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.
Thank you,
Pascal Chevrel
