- an editing history for posts
- community posts - a new kind of publication or bookmark post that can be edited and improved by the community of all users, such that especially for publications the metadata can be completed or corrected
- a complete overhaul of BibSonomy's group mechanisms, introducing group roles like group admin and group moderator, as well as a much easier way to request and to join new groups and to invite users
- approved posts - users can now obtain the ability to approve the quality of a post's meta data and mark the post accordingly.
We also improved our Pingback implementation, the sync api, and as always various scrapers.
