Messaging Layer Security (MLS) has been accepted by the IETF for publication as a standard. MLS is and #EndToEndEncryption method designed for group messaging. I've been working on integrating a variant of it with @Matrix.org (keep an eye out for demos coming soon). I've sat in on some of the IETF meetings, and the (not yet published) RFC may even contain some words that I've strung together. Congratulations to everyone who worked on it!
