Software news

Clients and applications

  • Gajim 1.7.3 has been released. This release enables you to mute notifications for specific contacts and brings some improvements and bug fixes.


  • ejabberd 23.04 has been released. This a big new release with many changes including support XEP-0425 (Message moderation), Real-Time Block List for MUC rooms and several SQL improvements.

Libraries & Tools

  • QXmpp 1.5.4 and QXmpp 1.5.5 have been released! They fix some important bugs.
  • Web Console Chat has been released. This is an installation guide and a collection of patches to make sure existing XMPP console clients are safe enough before serving them to the web with ttyd for your web-chat service.

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 XEPs 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 0.2.0 of XEP-0472 (Pubsub Social Feed)
    • Change the pubsub#type to be consistent with other XEPs
    • Add a Discovery section (tj)
  • Version 0.4.1 of XEP-0356 (Privileged Entity)
    • Fixed some typos (gh/@bodqhrohro)
  • Version 0.2.0 of XEP-0428 (Fallback Indication)
    • Add ‘for’ attribute such that entities can discover what the fallback is for.
    • Allow to specify that only one of or is meant as a fallback.
    • Allow to specify the part of respective text that is meant as fallback where applicable.
    • Don’t use encryption example, which should use XEP-0380 instead. (lmw)
  • Version 0.4.0 of XEP-0388 (Extensible SASL Profile)
    • Bump namespace
    • Add reference to and
    • Update security considerations and business rules
    • Clarify and tasks
    • Add expansion point to inline stream resumption and BIND2 (and possibly others)
    • Add optional element
    • Move from Deferred to Experimental (tm)
  • Version 0.4.0 of XEP-0386 (Bind 2)
    • Various changes, made in parallel with working client and server implementation experience, and SASL2 updates.
    • More tightly define the integration with XEP-0388 and several session feature XEPs: XEP-0198, XEP-0280, XEP-0352.
    • Replace the custom latest-id element with the new metadata element from XEP-0313, which also provides richer information.
    • Drop unread tracking, as this is a deep topic not directly related to resource binding. Instead the details of integration with other extensions have been better defined and demonstrated, to allow such functionality when it is fully defined and exists.
    • Adjust proposed namespace on aesthetic grounds and consistency with SASL2’s approach. As this protocol may become part of the new preferred connection flow for a long time to come, it makes no sense to include the redundant and potentially confusing ‘2’ when there is no conflict without it. Similarly, the ‘.0’ has been dropped from the XEP’s title, as it isn’t really a version number.
    • Allow the client some influence over the resulting resource identifier, and define a standard format for these combined identifiers.
    • Specify that servers should terminate old sessions from a client when it binds a new resource. (mw)
  • Version 0.7.0 of XEP-0359 (Unique and Stable Stanza IDs)
    • Add security consideration regarding spoofability and reference example (fs)
  • Version 0.12.0 of XEP-0292 (vCard4 Over XMPP)
    • Remove raw-IQ mode and specifies the reuse of PEP (spw)

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 help improving 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.

Call for Experience

A Call For Experience - like a Last Call, is an explicit call for comments, but in this case it’s mostly directed at people who’ve implemented, and ideally deployed, the specification. The Council then votes to move it to Final.

  • No Call for Experience this month.
