In the download area you can download Alan V3 and related material. Alan v3 is in beta state, almost feature complete and no major incompatibilities with the actual release is foreseen. This means that a game developed with a beta release should work as-is without re-compilation even after the official release of 3.0. However, bugs or other problems that are discovered during the beta period might trash this intent. Download the manual and read up on the section on conversion!
The beta releases are officially supported for production work. They have been rigorously tested automatically (about 500 automated test cases of different types) prior to release. Any feed-back will be much appreciated!
You can also download the latest, smoking, development snapshots. These are directly off the development team and have no guarantees, but you are welcome to try them out.
You can read the changes between versions in the Changes section.
