No, it isn't. Else we'd be at v0.1xx or greater. You're right in principle though. A proper document management by version number alone would increment said number with each release. If we were forced to specify we have a doc management by version number and date - please see the Release Notes.
Addendum: As soon as we launch some physical calculators we'll behave and do document management following the simple textbooks for sake of ... simplicity ... and clarity. Almost promised.
Alas, I'm afraid there are still a lot of functions to be coded - some 50% I'd guess. We're still open to supporters and collaborators (sounds like labor quite rightly), so whoever has the necessary capabilities and spare time to dedicate to this project (and looks for eternal fame in the community ) shall feel free to apply for these tasks.
