This shouldn't change until you're ready to release. Your improvements should go in this pr and that should be merge, you would then increment the version when you are ready to release.

Since the previous version was 0.0.9 going to 0.1.0 is legit. But that is t a decision you can make right now. Maybe you merge this an do a bunch more work and when we decide to release this is the real deal 1.0. Can't make version decisions until release time. Also check out http://semver.org/ for details on how to version and how version bumps should progress.
