We are proud to announce the release of jsxc, jsxc.owncloud, jsxc.nextcloud and jsxc.sogo 3.1.
This release will add 3 new XMPP Extension Protocols (XEP), the long-awaited possibility to share your screen with your contact and a lot of minor improvements. For a full list of changes, see our change log below. We recommend to update as soon as possible.
If you find bugs report them to our issue tracker and translate missing segments on webtranslateit.
Thanks to everyone who contributed. 
(Please don't get confused by the first bug fix release, but it was necessary, because shortly after releasing 3.1.0 we detected a build failure.)
