The 50th release of the XMPP Newsletter!

This is the 50th release of the XMPP Newsletter since it started in February 2019. We think it is worth to celebrate this achievement and say thanks to all the contributors as well as all our readers! Back at the Summit in Brussels, JC Brand, Nicolas Vérité (Nyco) and Severino Ferrer (S0ul) proposed and initiated the XMPP Newsletter. Since then almost every month there has been a release full of news from the XMPP universe. Hence, we are looking forward to the next releases and invite you to participate in this community effort! We would love to see more contributors as well as more translations of the XMPP Newsletter. Read more about how to help below.

That being said, welcome to the 50th edition of the XMPP Newsletter, great to have you here again! This issue covers the month of March 2024.

XMPP Events

  • XMPP Italian happy hour [IT]: monthly Italian XMPP web meeting, every third Monday of the month at 7:00 PM local time (online event, with web meeting mode and live streaming).


  • Last November the Linux Inlaws Podcast hosted Edward and Matt from the XSF Board 2024. The episode has been published recently and can be accessed via


Axel Reimer published an XMPP app decision table. It compares typical instant messaging features of popular XMPP apps and might be a guideline for new users who want to try an XMPP app. The table is available in English and German.

You can now ask all your questions about XMPP Providers in the new support chat. That chat is hosted on an own XMPP server which is set up with the new XMPP Providers Server project. It is a simple, Ansible-based all-in-one server setup that can be used for your own XMPP server as well.

Snikket Hosting is now publicly available! The launch is about providing new ways to get started with Snikket, not replacing the options that are already available. If you are already self-hosting Snikket, or planning to, nothing is changing for you. Though please do donate to support the project, even a little helps!

Libraries & Tools

  • A new release of go-xmpp 0.1.4.
  • A new release of go-sendxmpp 0.9.0.

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.


  • Version 0.1.0 of XEP-0485 (PubSub Server Information)
    • Promoted to Experimental. (dg)

    • Promoted to Experimental (XEP Editor: dg)
  • Version 0.1.0 of XEP-0490 (Message Displayed Synchronization)

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.
