-## [23.2.0] - 2023-06-16
-### Changes
-
-<details><summary> <b>Big Feature: MSAA</b> </summary>
-
-> The return of a long forgotten feature, with optimizations and improvements
-> Noticeable reduction to artifacts caused by subpixel geometry and glinting.
-</details>
-
-<details><summary> <b>Big Feature: SCPUI</b> </summary>
-
-> A 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.
-</details>
-
-<details><summary> <b>Big Feature: Localized Volumetric Nebulae</b> </summary>
-
-> Allows specifying a POF as the "hull" of a nebula, which will be rendered using ray marching
-> Further details can be found on the [GitHub Pull Request](https://github.com/scp-fs2open/fs2open.github.com/pull/5231)
-> Note: As this is a new feature, many improvements and optimizations remain to be made
-> Adapted from Andrew Schneider's 2015 SIGGRAPH talk "The real-time volumetric cloudscapes of Horizon: Zero Dawn"

 Deprecations are a mechanism in FSO where a certain feature or aspect of the engine has changed or is no longer supported. Since this would normally break existing mods we have the mod table feature "[tt]$Target Version:[/tt]" with which a mod can specify what version of FSO it was developed with. The features listed above will be removed or changed when the target version of a mod is at least the version released in this post.
