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).

Proposed

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.

• TLS Channel-Binding Downgrade Protection
  • This specification provides a way to secure the SASL and SASL2 SCRAM handshakes against channel-binding downgrades through TLS version downgrades.

New

• No new XEPs this month.

Deferred

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.

Updated

• Version 0.2.0 of XEP-0449 (Stickers)
  • Make pack attribute explicitly a MAY. Add more details about sending/receiving stickers without a sticker pack. (lmw)
• Version 0.2.0 of XEP-0463 (MUC Affiliations Versioning)
  • Use a dedicated child element of <x/> rather than namespaced attributes. (lmw)
• Version 0.3.0 of XEP-0503 (Server-side spaces)
  • Fix pubsub node field name in room disco info.
  • Specify how to attach images (avatar and banner) to a space. (nc)

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.

Stable

• No stable XEPs this month.

Deprecated

• No XEPs deprecated this month.

Rejected

• No XEPs rejected this month.
