Is the update "stable"?

What I mean is, are there gonna be patches in the next few days or are we going with 4.0 for the foreseeable future (until 4.2 or whatever in a few months I mean)? Because I refuse to waste data and write cycles if I’m to have to update the game all over again the next day because 4.0.1 or something, and from what I hear, things are a bit messy at the moment.

From what @FTB and @PaSte said there will be some more when all platforms run on 4.0, but when they did not say.

I think the server update today fixed some of the issues. It should be a little more stable, at least, it seems to me like it is
