Technically it hasn't been a year in development. What has changed is our versioning methodology.

Previously we purposely didn't increment the version to 2.0 despite the fact some 1.9.x releases (of which there were many over the last year) included features as well as maintenance, bug and security patches. This is why the current 1.9.x release is 1.9.19.6.

We've changed how we are handling version numbers going forward. Feature releases will be vX.X, maintenance releases will be vX.X.X and interim builds (a bit like WordPress nightly builds) are vX.X.X.X.

Only maintenance releases and feature releases are deployed via automatic update. Interim builds are only available via our support site until it's pushed out via automatic update.

So the next feature release will be 2.1, then 2.2 and so on. Which is more in line with how WordPress does things from a versioning standpoint.
