How to Know If ModernFix-mVUS Is Right for Your Minecraft Version
ModernFix-mVUS exists specifically for Minecraft versions that the official ModernFix releases do not cover. If you are unsure whether you should be using it, the answer depends entirely on which version you play.
Understand the Fork's Purpose
This mod is a fork that publishes builds for versions outside the official release range. It also stops releasing builds once the official ModernFix supports a given version. That means the fork is a stopgap, not a permanent replacement. If your version is already handled by official releases, use those instead and skip this fork entirely.
Match the Mod to Your Version
Check the Minecraft version your modpack or launcher is running. If official ModernFix does not list a build for that version, ModernFix-mVUS is likely the intended option. If official builds do exist for your version, the fork will not add anything you cannot get elsewhere, and mixing both is unnecessary.
Plan for Version Upgrades
Because the fork retires builds once official support arrives, you may need to swap mods when you update Minecraft. Before upgrading, check whether official support now covers your target version. If it does, remove ModernFix-mVUS and switch to the official mod to stay on the maintained path. Keeping both installed is redundant and can cause conflicts.
