Big Feature: MSAAThe return of a long forgotten feature, with optimizations and improvements. Noticeable reduction to artifacts caused by subpixel geometry and glinting.
Big Feature: SCPUIA modernized approach to defining menus in FS
Tired of having your Menus in FSO be at a resolution of potato? Use SCPUI to have them rendered from Fake-HTML to the actual screensize as opposed to a prebuilt graphics!
Tired of being limited to whatever people in the SCP hardcoded in for buttons? Use SCPUI to define buttons and all other manner of shenanigans as Lua-code just as you like.
Tired of needing to replace a bajillion interface graphics to reskin FSO? Use SCPUI, and especially Mjn's existing collection of Lua, CSS, Fake-HTML and images, and you only need to replace about 250 graphics.
Big Feature: Localized Volumetric NebulaeAllows specifying a POF as the "hull" of a nebula, which will be rendered using ray marching
