A significant update for a popular game has disrupted the ecosystem of mods and saved games. Valve has introduced new version control options for Steam Workshop to help players select compatible mod and game versions more easily. These options include new Steam APIs that allow developers to define past game versions and enable mod authors to specify compatibility with specific game versions. The new features can automatically manage version mismatches, allowing Steam to close the game, switch to the appropriate version, and relaunch it if a player attempts to use an incompatible mod. This requires cooperation from developers and mod authors to implement the necessary configurations.
