Please take care of yourself, seek help and also have an eye even on your virtual colleagues! Searching for help in your current location may be more satisfying, however this could be a start:

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.

  • Disco Feature Attachment

    • This specification provides a way to indicate that a feature is implemented for a specific namespace
  • Pubsub Caching Hints

    • This specification provides a way to get caching information from a Pubsub node


  • No new XEP 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.


  • Version 1.0.0 of XEP-0429 (Special Interests Group End to End Encryption)

    • Accepted by Council (XEP Editor: jsc)
  • Version 0.2 of XEP-0413 (Order-By)

    • Add a way to discover on which protocols Order-By applies
    • Remove references to SQL (except in implementation notes)
    • Specify that order-by operate on the whole item set and inside a RSM result set
    • Explicitly says that creation and modification dates are set by Pubsub service itself
    • Specify that Clark notation should be used for extensions
    • Add a full example with Pubsub and RSM
    • Add hint for SQL based implementations removed XEP-0060 and XEP-0313 as dependencies, they are mentioned as use cases, but are not mandatory
    • Better wording following feedback
    • Namespace bump (jp)
  • Version 1.0.0 of XEP-0381 (Internet of Things Special Interest Group (IoT SIG))

    • Integrate various comments from various sources (dwd)

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 Last Call this month.


  • No Draft 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. We really need more support!

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
