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.

  • No XEP was proposed this month.


  • No new XEPs this month.


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.


  • Version 2.5.0 of XEP-0030 (Service Discovery)
    • Add note about some entities not advertising the feature. (pep)
  • Version 1.34.6 of XEP-0045 (Multi-User Chat)
    • Remove contradicting keyword on sending subject in §7.2.2. (pep)

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.

  • XEP-0421: Anonymous unique occupant identifiers for MUCs
  • XEP-0440: SASL Channel-Binding Type Capability


  • Version 1.0.0 of XEP-0398 (User Avatar to vCard-Based Avatars Conversion)
    • Accept as Stable as per Council Vote from 2024-04-30. (XEP Editor (dg))


  • No XEP deprecated this month.


  • No XEP rejected this month.

Do not hesitate to join the discussion in our Comm-Team group chat (MUC) and thereby help us sustain this as a community effort. You have a project and want to spread the news? Please consider sharing your news or events here, and promote it to a large audience.

Tasks we do on a regular basis:

  • gathering news in the XMPP universe
  • short summaries of news and events
