0.5.0:

• The Earth world type now uses all new 3D terrain, no longer based on a simple height map, allowing for vastly more interesting terrain
  • The previous earth generator is now Earth (Legacy). Your world will be automatically upgraded to the new type. To keep the old generator, set the worldGenSaveKey in zoneInfo.json to base:earth_legacy,
• Added the Workbench block, which can rename and modify items- for now it can just change the color of laser guns,
• Added Pixel Displays, which change color depending on the laser that hit it last,
• Added Iron Ladders,
• Added /difficulty command,
• Added a health bar to the remote control screen to view the health of the mob you are looking at,
• Added footstep sounds to blocks,
• Added the Revolver- for now it has only 6 durability and can be crafted with 1 iron ingot. This will change in the future.,
• Added the Rifle (but it's currently unusable and unobtainable),
• Torches are now generally brighter,
• Falling blocks no longer have buoyancy,
• Massive speed up to world generation, such that it no longer stalls generating caves or corn fields,
• Data modding: Added basic item events, so that food among a few other items are data-moddable,
• Moved block events to the game_events/block_events folder- Update your datamods!,
• Fixed bug where custom screens could no longer display items
