Notes

• You can easily use a custom version of authlib-injector on an instance. Select the instance in the main window, click "Edit" (or Ctrl+I/Command+I), go to the Version tab, click "Add Agents", and select your authlib-injector JAR. If your JAR is not correctly identified as authlib-injector, make sure the Agent-Class field in the JAR's MANIFEST.MF is moe.yushi.authlibinjector.Premain.
