Today we released BibSonomy 2.0.29 which includes some smaller updates that nevertheless might help you a lot: * The tag search now supports the "but not" negation, i.e., you can search for posts that have some tags but not some other tags using the system tag sys:not:TAG. For example, you can get all posts that have the tag folksonomy but not the tag bookmarking by searching for folksonomy+sys:not:bookmarking. * Firefox and Chrome add-ons now replace the well-known bookmarklets - you can get them from the buttons page. * We included tag autocompletion on some places, including the editTags page and at the quick tag editor in post lists. * We made the layout using less space on your screen (reload the page with Shift-F5 to see the effect). * The QR code scanner is now also available to post publications.Release 2.0.29
