🔒 Dependency Bounds Specification (fabric.mod.json)

To prevent pre-release locks while ensuring stability, Speedometer uses open-ended lower bounds (>=) in fabric.mod.json:

"depends": {
  "fabricloader": ">=0.15.0",
  "minecraft": ">=26.2"
}

• Fabric Loader: Minimum 0.15.0 required for Java 25 classloading.
• Minecraft Target: Open-ended >=26.2 bound ensuring compatibility across modern Minecraft 26.x updates.
