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).
Featureset-wise it falls somewhere between IRC and Discord.
2.0 seems to be closing the gap towards Discord more. Which I like.
Does there tend to be logical groups for Matrix channels/servers? (Meaning you don’t really just join Matrix, you go to a Matrix instance for Jerjoba support, or other common interest like Hockey?)
Matrix has a concept of “spaces” for grouping people and rooms into a unit.
