We are pleased to announce ejabberd 20.04. In addition to various bugfixes and improvements, this release massively improves audio and video calls support.

ejabberd 20.04 now implements XEP-0215: External Service Discovery, via the new mod_stun_disco module, which allows XMPP clients to discover STUN/TURN services and to obtain temporary credentials for using them.

The format of the temporary credentials handed out to clients is described in an IETF draft. Therefore, in addition of the ejabberd 20.04 built-in STUN/TURN support, the module can also be used with external STUN/TURN servers that support the same draft (such as coturn or restund). It also allows (non-XMPP) WebRTC applications to use ejabberd 20.04 built-in STUN/TURN support.

To promote this usage, STUN/TURN service is now enabled by default starting ejabberd 20.04.

It means that ejabberd 20.04 can now be used by modern clients with audio/video calls features. if you want to test it, Conversation or Movim clients already support XEP-0215.

See Changelog below for a list of the other changes in this release.
