Amazing update as always! Trigger volumes are so exciting for modding and adventure maps, there is so much potential here. Minecraft had something similar using command blocks but IIRC it was very awkward and hacky to use.

New music is always nice. Server browser is great but I'm a bit worried that people might try to game the system so their servers appear on top.

Chat commands autocomplete is a small but very welcome change. I trip up on commands because I often have many too mods that do different things.

FYI the devs said they were working on a big content update alongside these technical changes, but haven't said when that would be coming. I just want Worldgen v2, myself...
