This talk starts at 13:15 and ends at 13:45 hs.(UTC+1:00)
  • Movim: Building a Decentralized Social Network on XMPP: In this talk, Timothée Jaussoin will present how Movim leverages the XMPP standard and its extensions to deliver features users expect from modern social platforms (communities, IM, group chats, video calls, blogging and a complete publishing platform into a unified experience), without giving up your data to a centralized platform, while remaining fully federated, interoperable with other XMPP clients like Conversations and Dino, and capable of bridging to centralized platforms like Discord, Telegram, and WhatsApp!. This talk starts at 13:45 and ends at 14:15 hs. (UTC+1:00)

• XMPP at 39C3 CCC: the Critical Decentralisation Cluster (CDC) returned to the 39th Chaos Communication Congress in Hamburg (Germany) during this last December 27-30 2025. The CDC provided a friendly space for discussions and exchanges on technology and politics with other communities working towards decentralization. The XMPP assembly was part of it thanks to neox and mathieui active involvement, with the latter being responsible for the sparkly XMPP stickers!!

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).

Proposed

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.

• Initial Authentication Pipelining
  • This specification defines a protocol for discovering if the SASL2 <authenticate> can be pipelined safely along with the stream open, and if so allows the client to perform this pipelining safely.

New

• Version 0.1.0 of XEP-0508 (Forums)
  • Accepted as Experimental by council vote (dg)
• Version 0.1.0 of XEP-0509 (Initial Authentication Pipelining)
  • Accepted as Experimental by council vote (dg)

Deferred

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.

Updated

• Version 1.35.3 of XEP-0045 (Multi-User Chat)
  • muc#roomconfig_allowinvites doesn’t restrict owners but enables additional permissions for members. (spw)
• Version 0.7.0 of XEP-0353 (Jingle Message Initiation)
  • Remove local redefinition of jingle <reason/> element in XML schema and reference existing.
  • Make usage of <reason/> element optional in schema, as specified in the text.
  • Add missing definition of ’empty’ type in XML schema. (lnj)

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 can help improve the XEP before returning it to the Council for advancement to Stable.

• Last Call for comments on XEP-0377 (Spam Reporting)
  • This Last Call begins on 2025-12-12 and shall end at the close of business on 2026-01-05.

Stable

• Version 1.0.0 of XEP-0440 (SASL Channel-Binding Type Capability)
  • Accept as Stable as per Council Vote from 2025-11-18 (XEP Editor (dg))

Deprecated

• No XEPs deprecated this month.

Rejected

• No XEPs rejected this month.
