Carbon Loader Update (2.2)
The carbon loader has been re-worked from the ground up with security AND user-experience in mind. We have tested and optimized loader speeds, memory usage and startup time. The new loader is 10x faster than the previous loader.

Download your loader again. (Chose Retention-Carbon-ARM, if your CPU architecture is arm64.)

Note: WINDOWS support will only be given specifically to those who run Windows RDP hosted servers. If you do, please make a ticket at on our discord.

• Reverted Expert knockback profile changes back to normal.
• Improved performance and reduced CPU usage and ram usage.
• Fixed Exit codes and shutdown logic (Reported by @im_a_blobfish ).
• Fixed invalidly placed blocks not updating properly (Reported by @quadflame & @refrainsclub)
• Fixed Bukkit world unloading not working properly for Optimized Region File cache and file implementation.
