The development sped up and thanks to the feedback we got from users we can release another version this week.
This new version is alot more stable and usable - we fixed the PHP4 backward compatibility and other problems. We even added a small new feature: - captcha input for the registration form.
If you want to be safe and sound do no use this version for production - the braver ones are allowed to do so. We fixed almost every issue reported to us this week and we will continue to do so if you, the users, are helping us with your feedback, bug reports, translations etc.
Now have fun with this new version and download it here.
