<br>
On August 26th, we will be merging Firefox 70 from mozilla-central to beta<br>
for the first time. In order to avoid invalidating the testing we get<br>
out of late Nightly and the early Developer Edition builds and to ensure<br>
that we can roll out Beta 70 to a wider audience with confidence, we'd<br>
like to ask that any risky changes be avoided from July 1st until after<br>
the version bump to 71 on Sept 2. Please also be mindful of any<br>
landings late this week or over the weekend as there will be very little<br>
buffer between the first merge and shipping the 70.0b1 builds.<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,<br>
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 affects the current Nightly version) — be<br>
mindful that code behind NIGHTLY_BUILD or RELEASE_OR_BETA ifdefs can<br>
lead to unexpected CI results<br>
- Flip prefs that enable new Features that were untested in Nightly 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>
