Soft code freeze for Firefox 117 starts on July 27

[Ryan VanderMeulen]

Hello,
With Firefox 116 in the Release Candidate phase this week, we are nearing the end of the Nightly 117 cycle.

In order to avoid invalidating the testing we get out of late Nightly and to ensure that we can roll out Beta 117 to a wider audience with confidence next week, we'd like to ask that any risky changes be avoided from Thursday, July 27 until after the version bump to 118 on July 31.

Also, please be advised that string freeze for Firefox 117 begins Friday, July 28. 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,
Ryan VanderMeulen
Firefox Release Manager
