Version 2.5.0 of XEP-0030 (Service Discovery) has been released.
Abstract:
This specification defines an XMPP protocol extension for discovering
information about other XMPP entities. Two kinds of information can be
discovered: (1) the identity and capabilities of an entity, including
the protocols and features it supports; and (2) the items associated
with an entity, such as the list of rooms hosted at a multi-user chat
service.
Changelog:
Add note about some entities not advertising the feature. (pep)
