Added

• Added selection commands for:Dimension
  • Shape
  • Centre
  • Radius
  • Region corners
  • Relighting mode
• Added /luc selection to display the current configuration.

Changed

• Updated to Minecraft 26.2.

• Updated Fabric API to 0.157.0+26.2.
• Updated Fabric Loom to 1.17.
• Updated Gradle to 9.5.1.
• Updated ModMenu to 20.0.1.
• Reworked commands into a Chunky-style configure-then-start workflow:

  /luc world [dimension]
  /luc shape <square|circle|rectangle|world>
  /luc center [x z]
  /luc radius <radius> [radiusZ]
  /luc corners <x1 z1 x2 z2>
  /luc mode [missing-only|full|full-2-pass]
  /luc selection
  /luc preview
  /luc start
  /luc progress
  /luc pause
  /luc continue
  /luc cancel
  

• Simplified dimension discovery and world-folder resolution using direct Minecraft 26.2 APIs.
• Simplified chunk tracking and resend handling.
• Updated the configuration screen for Minecraft 26.2.
• Updated the README with the new workflow and examples.

Optimised

• Removed over 800 net lines of obsolete compatibility and duplicate command code.
• Avoided calculating chunk ticket areas twice during task submission.
• Reduced the number of required mixin accessors.
• Replaced reflection-based API discovery with direct calls to Minecraft 26.2 APIs.

Security

• Persisted chunk NBT is now read with a bounded allocation quota instead of allowing unlimited heap allocation.

Removed

The following redundant commands and command variants were removed:

• /luc estimate
• /luc status
• /luc dimensions
• /luc reset
• /luc region
• /luc resume
• Direct coordinate arguments under /luc start
• Direct coordinate arguments under /luc preview Use /luc progress instead of /luc status, and /luc continue instead of /luc resume.

Breaking changes

Existing scripts or command blocks using removed command variants must be updated to the new selection workflow.

For example:

/luc world minecraft:overworld
/luc shape circle
/luc center 0 0
/luc radius 5000
/luc mode missing-only
/luc preview
/luc start
