Hi all,<br>
<br>
With Firefox 76 RC shipping soon, we are nearing the end of the
Nightly 77<br>
cycle.<br>
<br>
In order to avoid invalidating the testing we get out of late
Nightly and<br>
to ensure that we can roll out Beta 77 to a wider audience with
confidence,<br>
we'd like to ask that any risky changes be avoided from Thursday
April 30<br>
until after the version bump to 78 on May 4.<br>
<br>
Some reminders for the soft code freeze period:<br>
<br>
Do:<br>
- Be ready to back out patches that cause crash spikes, new crashes,
severe<br>
regressions<br>
- Monitor new regressions and escalate merge blockers<br>
- Support release management by prioritizing fixing of merge
blockers<br>
<br>
Do Not:<br>
- Land a risky patch or a large patch<br>
- Land new features (that affect the current Nightly version) — be
mindful<br>
that code behind NIGHTLY_BUILD or RELEASE_OR_BETA ifdefs can lead to<br>
unexpected CI results<br>
- Flip prefs that enable new Features that were untested in the
Nightly<br>
cycle<br>
- Plan to kick off new experiments that might impact a feature's
merge<br>
readiness<br>
<br>
Please let us know if you have any questions/concerns.<br>
<br>
Thanks,<br>
Pascal & the Release Management team
