We will not be updating to snapshot 15w31a, or 1.8.8.
15w31a reasons are because It is extremely buggy, practically unstable, and pretty much a mine field for maps.
1.8.8 reasons is because, It does nothing to servers.. It only changes things for clients, and realms.
(Spacing is not carried over to this news post, please see our Tumblr or Facebook to see a better format.)
