So two weeks have passed, and the merge window was pretty normal and is now closed.
This does not seem to be shaping up to be a particularly big release, and there seems to be nothing particularly special about it. The most special thing that happened is purely numerology: we've passed the six million git objects mark, and that is reason enough to call the next kernel 5.0. Except I probably won't, because I don't want to be too predictable. The version numbers are meaningless, which should mean that they don't even follow silly numerological rules - even if v3.0 and v4.0 happened to be at the 2M and 4M mark respectively.
But v5.0 will happen some day. And it should be meaningless. You have been warned.
