55 Sounds like a big improvement. I'm not too familiar with CI, so forgive me if this is obvious: should overlays now use the 'stable' branch as their primary remote, so they can ensure that any breakage introduced is caused by their own overlay instead of a flub by us? If so, then I wonder if this will help indirectly improve overlay quality.
57 Being able to say "as of X commit, the tree is in good shape" is a big deal imo. Thanks for working to make that happen. Is there anything other devs can do to assist your development, or do we stick to the usual 'if in doubt talk to QA'?
