The VSCode extension "COMP/CON Content Authoring" is no longer being maintained and will be removed from the VSCode marketplace. Please use the new "COMP/CON Content Tools" extension instead, which can be found here.
COMP/CON Content Tools currently supports C/C v2 and will support C/C v3 after release. For questions, comments, or more information, please check the #COMPCON channel in the Lancer Discord.
