<div dir="ltr">Hi all,<br><div>
<br>
With Firefox 86 RC shipping soon, we are nearing the end of the Nightly 87 cycle.<br>
<br>
In order to avoid invalidating the testing we get out of late Nightly and to ensure that we can roll out Beta 87 to a wider audience with confidence next week, we'd like to ask that any risky changes be avoided from Thursday February 18 until after the version bump to 88 on February 22.<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 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 that code behind NIGHTLY_BUILD or RELEASE_OR_BETA ifdefs can lead to unexpected CI results<br>
- Flip prefs that enable new Features that were untested in the Nightly cycle<br>
- Plan to kick off new experiments that might impact a feature's merge readiness<br>
<br>
Please let us know if you have any questions/concerns.<br>
<br>
Thanks,</div><div>Julien</div><div>-- <br></div><div>Firefox Release Manager<br></div></div>
