Version 2.1.0 of the Simple Review component and modules has been released. There have been numerous fixes and small features added (most of which have been covered in beta releases), of course the main point is that it now runs natively on Joomla 1.5. I have included a German translation in the main release (look out for translation instructions soon).
If you find any problems please post them in the forum.
An upgrade path for existing users will be made available in the next few days.
