No, that's not a typo. For the last 10 years, there's been talk of a
mythical 3.0 release, which would brake backwards compatibility. But
we never did and we won't. So from now on we'll skip the '2.' in
Ariadne version numbers. The next major release will be 8.0 and not
2.8.0. Read here what we have in mind for it:
