• For changes in the 3rd version digit, for instance from 1.3.1 to 1.3.2, only bug fixes have occurred.
• For changes in the 2nd version digit, for instance from 1.3.1 to 1.4, more features have been added.

But until 1.0 is out, you may experience the full range of incompatibilities at any point.

Below you will find the release notes of the pre-1.0 releases as they are made.
