Deprecations:None
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 "
$Target Version:" 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.
