Welcome to the XMPP Newsletter, great to have you here again! This issue covers the month of April 2022.

Like this newsletter, many projects and their efforts in the XMPP community are a result of people’s voluntary work. If you are happy with the services and software you may be using, especially throughout the current situation, please consider saying thanks or help these projects! Interested in supporting the Newsletter team? Read more at the bottom.

XSF Announcements

XSF and Google Summer of Code 2022

  • The XSF has been accepted as hosting organization at Google Summer of Code 2022 (GSoC).
  • XMPP Newsletter via mail: We migrated to our own server for a mailing list in order to move away from Tinyletter. It is a read-only list on which, once you subscribe to it, you will receive the XMPP Newsletter on a monthly basis. We moved away from Tinyletter due to privacy concerns.
  • By the way, have you checked our nice XMPP RFC page? :-)

XMPP Community Projects

A new community space for XMPP related projects and individuals has been created in the Fediverse! Join us on our new Lemmy instance and chat about all XMPP things!


Are you looking for an XMPP provider that suits you? There is a new website based on the data of XMPP Providers. XMPP Providers has a curated list of providers and tools for filtering and creating badges for them. The machine-readable list of providers can be integrated in XMPP clients to simplify the registration. You can help by improving your website (as a provider), by automating the manual tasks (as a developer), and by adding new providers to the list (as an interested contributor). Read the first blog post!

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).

By the way, features a new page about XMPP RFCs.


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 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 0.4 of XEP-0356 (Privileged Entity)
    • Add “iq” privilege (necessary to implement XEPs such as Pubsub Account Management (XEP-0376)).
    • Roster pushes are now transmitted to privileged entity with “roster” permission of “get” or “both”. This can be disabled.
    • Reformulate to specify than only initial stanza and “unavailable” stanzas are transmitted with “presence” pemission.
    • Namespace bump. (jp)

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 XEPs advanced 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.
