I will eventually release the latest server build of SRB2U+ here if there are any major changes or bug fixes.
This one has quite a lot of fixes and some pretty hot changes.
Fixed OpenGL viewport stretching at high resolutions
Fixed sound effects shifting
Fixed discord invites not working
Updated EXE with the uncapped plus logo
Implemented custom character support on rich presence
Experimental Lua interpolation support (fixes addons like L_PaperPeeloutCD-v1.2.pk3)
Now you can hide the character that you are playing from your discord rich presence status in the Options Menu -> Data Options -> Discord Options -> Show Character On Status.
As for the custom character support in rich presence:
If you want to add your character CSS to appear on rich presence, contact me on discord or on the mb and send a full res version of your character CSS and skin name.
Here's a pretty raw list with all the custom characters skinnames that are currently supported: http://srb2.mooo.com/SRB2RPC/customcharlist
