This is a small update to add proper support for copper doors in Minecraft 1.21. Also note that support for versions before 1.20.6 is now officially dropped, and LWC 2.3.2 should be used instead for those versions. Java 21 is also now required.

Changelog:

• Added copper doors and trapdoors to the default configuration
• Updated door matchers to properly support copper doors
• Improved server startup time by opting out of remapping on Paper
• Updated Chinese translation (@NayaCcR)
