It took almost three months to create a new version. The reason is simply that there are not many new features left to be done and that we are now focussing our efforts on the mobile app.
Most of the changes have happened behind the scenes: We have removed many bugs and increased the speed, and much has been done to help the mobile app play nicely with the server software. We also added a new feature: Users have been requesting the possibility to invite their friends to groups.
If you like to see it live, try it at the demo deployment. And stay tuned for soon upcoming news about the mobile app.
