Or it might be the unstable version of 0.10.

The dots are there for a reason.

IMHO, it should be followed by 0.12, because 0.10 is too confusable with 0.1, but 0.12 is clearly a new version...

They use a variation on semantic versioning, which is pretty standard:

    major.minor.revision

revision is incremented when backwards compatible bug fixes are added

minor is incremented when backwards compatible features are added

major is incremented when backwards incompatible change is introduced.

All of them are integers, and the smaller ones are reset to 0 when a bigger one is incremented.

For versions 0.x.x (pre v1), backwards incompatible changes are allowed at any time.

There are more rules, see http://semver.org/

imo next version will be 1.0 because they are on the fast releasing period

[JakaJancar]

Possibly, I'm just commenting on the logic that 0.9 is followed by 1.0 (or 1.9 by 2.0, if you want).
