Version 1.1 adds support for Minecraft 1.21. There is no version for 1.20.x due to the effort required to port the extensive internal changes to these versions. To use this mod on servers that run 1.20.x, you can install it on a 1.21 client and use ViaFabric or ViaFabricPlus.
This is the initial release of Disable Player Reporting! Please report any issues over at the issue tracker.
