If 2.1.x is finalised and merged into 2.2 then it needed to be bumped past the last 2.1.x, so v3.1.3. > I'm not sure what exactly should be done with that.

Otherwise it definitely doesn't feel right ;-). There is no need to skip over v3.1.3 since you haven't used it yet. As I see it, your options are v3.1.3 or v3.2.0, depdending on whether 2.1.x is considered a dead branch. Cheers, Kent.
