We now have a new version of GreenPepper that is compatible with Confluence 4.0. There is a stable beta version available. Those of you who are interested in testing it, you are more than welcome to do so. You will find more information on our EAP page here.
We are fine tuning the details and adding the last functionalities needed for a full release, more news before the end of the week.
Thank you
The GreenPepper Team
