As of now we are declaring this work a success! We have unfrozen Nightly updates for 10% of our userbase right now. We plan to update 100% of our users tomorrow after the next set of Nightlies are produced.
There are a few minor issues we are following up on at this time, but expect to have them resolved ASAP. This work was accomplished without closing the trees, so big thank you to everyone who made this milestone possible. ~Justin Wood (Callek) On Wed, Jul 26, 2017 at 10:54 AM, Justin Wood <jw...@mozilla.com> wrote: > This work has now begun. > > On Wed, Jul 26, 2017 at 9:13 AM, Justin Wood <jw...@mozilla.com> wrote: > >> Hello Everyone, >> >> Just a reminder that this work will be taking place in just under >> aproximately 2 hours.
