Charter: https://datatracker.ietf.org/doc/charter-ietf-mls/

The Messaging Layer Security (MLS) protocol, RFC 9420, specifies a key
establishment protocol that provides efficient asynchronous group key
establishment with forward secrecy (FS) and post-compromise security (PCS)
for groups in size ranging from two to thousands.

The MLS WG will maintain the protocol and will work on the
following MLS protocol extensions:

* Support for use of MLS in protocols developed by the MIMI working group
* Support for new credential types
* Support for common operational patterns in messaging applications
* Support for quantum resistance
* Framework for safe extensibility
* Detection of lost application messages
* Support for sending messages to individual members of a group

Many of the extensions to support these features will be included in
draft-ietf-mls-extensions, but some of the extensions will be published in
separate specifications.

Milestones:

  Dec 2024 - Submit MLS extensions I-D to IESG as Proposed Standard
