Subject Re: [DISCUSS] Looking to a 2.8.0 release
Date Tue, 21 Apr 2015 22:12:07 GMT
The feature set here seems pretty long, even for 2 - 3 months. Can we come
up with a minimum set of features (or a number of features) that justify a
new minor release, and start stabilizing as soon as those are in?
