ejabberd development keeps on its steady pace and we are energized by the growing momentum. Thank you all for your feedback and contributions for that release.

This new ejabberd release contains many many bugfixes, internal improvements, but also, as usual, some new features.

We are very excited by the experimental support for Mediated Information eXchange (MIX) we have added in ejabberd 16.03. This is the future of Multi User Chat for XMPP. While still rough, you can already give it a try and help improve the specification. You can learn more from our previous blog post: Experimental MIX Support for Group Conversations added to ejabberd

We have also started improvements of various third-party backends such a Microsoft SQL Server and LDAP. This is the beginning of a process to improve support of those backend, so please, bare with us and keep us posted on your results.
