Auto Updater

The updater reads each mod file in the mods directory and computes a SHA-512 hash for it. It then asks the Modrinth API for the latest version matching that hash, takes the first file listed, and saves its JAR into an updated subfolder inside the mods directory. Every saved file is checked against the hash Modrinth expects, and a file that fails the check is fetched again before the program moves on to the next one. JSON responses with several files are not handled, because the author notes that such entries do not seem common.

The workflow is meant to be checked by hand. The previous mods are moved into a backup folder, and the new files are moved from the subfolder into the main mods directory only after the player has looked them over. Once the player is satisfied, the old copies can be deleted, and the updated folder can be removed without affecting the game. A cancel button in the interface stops the process, and a key press in the world opens the screen.

Auto Updater is client-side only, so only the player's client needs it and servers do not. It requires Fabric API, and it is published only for Fabric. Its files target 26.2, with the latest one being 1.3.1+26.2, dated 2026-08-19. The source code and issue tracker are public, and the mod is released under the Apache License 2.0.
