Minecraft 1.21.5 — Client & Cheat Compatibility

Quick summary
1.21.5 has strong client support from actively maintained clients. Fabric and Forge loaders are available. Some older modules may need testing on this version because world generation and rendering changed slightly. Check the client compatibility table below.

Version-specific notes
- 1.21.5 introduced data-driven mob variants and decorative block sets. Rendering modules like ESP and Chams may need minor updates to handle new entity types.
- World generation added new biome features. X-Ray behavior is unchanged because it operates on block data, not biome data.
- Client builds for 1.21.5 were published later than those for 1.21.1. If you want maximum community-tested configurations, 1.21.1 remains the safer choice.
