Highlights include Sliding Sync (instant login/launch/sync), Native OIDC (industry-standard authentication), Native Group VoIP (end-to-end encrypted large-scale voice & video conferencing) and Faster Joins (lazy-loading room state when your server joins a room).
Been waiting for this for a long time! Another thing that’s been on the horizon I’m eagerly waiting for is p2p. They’ve been working on Dendrite, which is a much more efficient Synapse, and the goal is to be efficiently running it to effectively running it on your own device as like an invisible self-host. They’re working on MXIDs as well so @hostname.com wouldn’t be a thing anymore. P2p with all this other tech would make Matrix really the privacy holy grail imo.
Are you sure about that? I think they’ll still exist, but will be less meaningful, as a users identity will be backed by cryptography instead of their name with the HS name
afaik server domains would essentially just be aliases for a user’s UUID, like how it works with rooms.
