7.0.1 was the release candidate for 7.0.2 (stable).

Sounds like they learned their release numbering skills from the KDE folks.

I'm not sure if they do it but many projects use odd=unstable,even=stable version schemes including GNOME.

Yes, but that's usually in the second digit (e.g. 2.4 is stable, 2.5 is development) - switching from unstable to stable in a nominal patch release (third digit) is at least uncommon.
