No server updates out there :(


Smack 4.4.2 has been released, containing mostly bugfixes.

Extensions and specifications

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.


  • Version 0.2.0 of XEP-0456 (Content Rating Labels)
    • This specification provides a wire format in the form of a Service Discovery extension to allow services of various kinds to publish information about the kind of content they allow and/or endorse on their platform.
    • Describe the conversion algorithm. (jsc)


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 1.1 of XEP-0294 (Jingle RTP Header Extensions Negotiation)

    • Add mapping for a=extmap-allow-mixed (ph)
  • Version 0.2.0 of XEP-0408 (Mediated Information eXchange (MIX): Co-existence with MUC)

    • Fix reference to MIX-CORE namespaces (@mathieui)
  • Version 0.3.0 of XEP-0406 (Mediated Information eXchange (MIX): MIX Administration)

    • Fix reference to MIX-CORE namespaces (@mathieui)
  • Version 2.12.0 of XEP-0004 (Data Forms)

    • Clarify that the ‘reported’ element must appear before any ‘item’ element. (fs, jsc)

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 Draft.


  • No Drafts 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.

Help us to build the newsletter

We started drafting in this simple pad in parallel to our efforts in the XSF Github repository. We are always happy to welcome contributors. 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 write about it? Please consider sharing your news or events here, and promote it to a large audience! And even if you can only spend a few minutes of support, these would already be helpful!

Tasks which need to be done on a regular basis are for example:

  • Aggregation of news in the XMPP universe
  • Short formulation of news and events
  • Summary of the monthly communication on extensions (XEP)
  • Review of the newsletter draft
  • Preparation for media images
  • Translations: especially German and Spanish
