Puzzles Lib

What it's and who it's for Puzzles Lib is a library mod written by Fuzs. It doesn't add gameplay features on its own. Instead it supplies common code, utilities and APIs that other mods can depend on. If you are a player you only need it when another mod lists it as a required dependency. If you're a mod developer you can use it to avoid rewriting shared infrastructure. ## Supported loaders and Minecraft versions The mod runs on both Fabric and NeoForge. According to the project record the currently supported Minecraft versions are 1.21.1, 26.1, 26.1.1, 26.1.2 and 26.2. Older branches such as 1.20.x, 1.19.x, 1.18.x, 1.17.x and 1.16.5 are marked archived or bugfix only and no longer receive updates. ## Client and server requirements Both client side and server side are marked optional. And that means the library can be installed on just the client, just the server, or both depending on what the dependent mod requires. ## License The project is released under the Mozilla Public License 2.0. ## Recent development activity The repository shows active development on the 26.2.x branch with a latest release dated 2026-09-14. Recent changes include updated mouse scroll input events, new advancement and atlas providers for armor trims, a replacement for registry tag preparation, and an overload for generating loot tables from block set families. The 26.1.x branch remains maintained with backports and selected new features. ## What this means for you If a mod you want to play requires Puzzles Lib, install the version that matches your Minecraft version and mod loader. You do not need to configure anything. Developers looking for a shared utility library can reference the Maven coordinates published for each supported branch.
