Subject Re: Branch 1.4 update
Date Thu, 05 Oct 2017 18:11:46 GMT
As far as I know, Facebook's one use case is the only remaining known place

since the time we last talked about it some more fixes have gone in. Our
testing looks good. If they also see good results with latest branch-1.3 I
would be in favor of moving the stable pointer.
