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

Bifrost bridge fork at implemented offline messages support for matrix rooms accessed via the bridge XMPP users connecting to Matrix rooms via Bifrost bridge did not get offline messages, because group chat (MUC) history support was not implemented in the XMPP server implementation of the bridge (based on xmpp-js). Thanks to great work done by Maranda, we can now have history and also message history (MAM) support for Matrix to XMPP bridged rooms. See this post for complete instructions to use this feature.

The JMP Newsletter announces a new release of the Cheogram Android client, SMS-only phone number ports, deeper integration with Snikket, and a new project for social instance hosting.

Software news

Clients and applications

Gajim 1.4.0, 1.4.1, 1.4.2, and 1.4.3 have been released! After more than a year of development, it’s finally time to announce the release of Gajim 1.4! Gajim 1.4 series comes with a completely redesigned message window and conversation management. Workspaces allow you to organize your chats to keep matters separate where needed. These changes were only possible by touching a lot of Gajim’s code base, and we appreciate all the feedback we got from you.

Gajim’s new user interface

Psi+ portable 11.5.1627 (2022-05-21) and Psi+ installer 11.5.1629 (2022-05-31) have been released.

Jackal 0.60.0 has been released.

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 XEPs proposed this month.


  • Version 0.1.0 of XEP-0465 (Pubsub Public Subscriptions)
    • Accepted by vote of Council on 2022-04-13. (XEP Editor (jsc))
  • Version 0.1.0 of XEP-0466 (Ephemeral Messages)
    • Accepted by vote of Council on 2022-05-03. (XEP Editor (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 0.3 of XEP-0365 (Server to Server communication over STANAG 5066 ARQ)
    • Make use of SLEP Streaming service, which was not available for 0.1. This provides a better service mapping than direct use of 5066 and provides compression. (sek)

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.
