Extensions and specifications

The XMPP Standards Foundation develops extensions to XMPP in its XEP series in addition to XMPP RFCs.

Developers and other standards experts from around the world collaborate on these extensions, developing new specifications for emerging practices, and refining existing ways of doing things. Proposed by anybody, the particularly successful ones end up as Final or Active - depending on their type - while others are carefully archived as Deferred. This life cycle is described in XEP-0001, which contains the formal and canonical definitions for the types, states, and processes. Read more about the standards process. Communication around Standards and Extensions happens in the Standards Mailing List (online archive).


The XEP development process starts by writing up an idea and submitting it to the XMPP Editor. Within two weeks, the Council decides whether to accept this proposal as an Experimental XEP.

  • PubSub Server Information
    • This document defines a data format whereby basic information of an XMPP domain can be expressed and exposed over pub-sub.
  • Host Meta 2 - One Method To Rule Them All
    • This document defines an XMPP Extension Protocol for extending XEP-0156 by modifying the JSON Web Host Metadata Link format to support discovering all possible XMPP connection methods, for c2s and s2s


  • Version 0.1.0 of XEP-0484 (Fast Authentication Streamlining Tokens)
    • This specification defines a token-based method to streamline authentication in XMPP, allowing fully authenticated stream establishment within a single round-trip. Promoted to Experimental. (XEP Editor: kis)
  • Version 0.1.0 of XEP-0483 (HTTP Online Meetings)
    • This specification defines a protocol extension to request URLs from an external HTTP entity usable to initiate and invite participants to an online meeting. Promoted to Experimental. (XEP Editor: kis)


If an experimental XEP is not updated for more than twelve months, it will be moved off Experimental to Deferred. If there is another update, it will put the XEP back onto Experimental.

  • No XEPs deferred this month.


Last Call

Last calls are issued once everyone seems satisfied with the current XEP status. After the Council decides whether the XEP seems ready, the XMPP Editor issues a Last Call for comments. The feedback gathered during the Last Call can help improve the XEP before returning it to the Council for advancement to Stable.

  • No last call this month.


  • No XEP moved to stable this month.


  • No XEP deprecated this month.
