Memory Leak Fix (UNOFFICIAL)

A standalone Fabric port of Memory Leak Fix for Minecraft 1.21.1, based on the upstream 1.1.5 code by FX - PR0CESS. It carries three upstream leak fixes adapted for this Minecraft version.

Compatibility

• Minecraft 1.21.1
• Fabric Loader 0.16.14 or newer
• Java 21 or newer

Testing

The port was built and smoke-tested in the Fabric development client. It reached the title screen with all three mixins applied, and a short singleplayer world smoke test saved and closed cleanly. The final standalone release JAR has not yet had a separate installed-profile or long-duration stress test. No performance benchmark is claimed.
