There's a lot going on. Someone is doing a new third party viewer, Crystal Frost, in Unity. Linden Lab has a mobile viewer in alpha test. Rendering is PBR now for new objects. There are mirrors! Content upload is moving to glTF, to be compatible with everybody else. Voice is switching from Vivox to WebRTC. Game controller support is in test. New users get better avatars. The dev staff is larger.

None of this is yet increasing Second Life usership much, but it remains the best metaverse around.

I thought the metaverse thing was going to be bigger. Meta spent so much money to produce so little.
