Release 234 - 1.21.11 and Versioning overhaul

1.21.11 and Versioning overhaul

This is the last main update for the year, although there may be some minor patches over the next few weeks.

The default minecraft version has been updated to 1.21.11, along with some versioning overhauls to better handle future java and bedrock versions. Minecraft versioning is changing next year, so this update adds some groundwork to help support that.
