A long time has passed since the last update. We did a few releases but did not take the time to write a message about it. Today the demo site was updated to have the last released version (1.7.1p4), and we updated the download section to provide this latest release. An overview of what has changed can be found in the changelog.
Starting with the next version we will be moving our code to GitHub to make it easier to contribute to the project.
When you find bugs or encounter problems, please file a report in our bugtracker. Contributions to the documentation are greatly appreciated and we are more than happy to review your proposed changes!
