Some remars about version numbering.
0.0.x versions are testing version, sort of alphas. They are not guaranteed bug free, and are provided just for early adopters.

By the way, I thank all of you for your bugs and features requests.

When the app and the underlying will be more stable and feature complete, I will move to 1.0.0. 0.5.0 will mean "half of the goal reached" etc.
