Gameplay

• The Bag (throw all your trash loot in there and unpack it at your base)

• block selection and drops depends on tool type, you can only select and collect foliage with a sickle
• grass blocks are now craftable through grass seeds

• block selection is now based on the model, allowing you to select through holes in chiseled blocks
• tool stats are now rounded to their visual values in the background

• cave density can be configured per layer
• improved SDF system (rotation and cluster SDFs)
• parentEdgeDistance for subbiomes, makes islands more consistent
• biomes are now placed on a hexagonal grid, reducing the impact of grid artifacts
• surface caves are more connected, and it should be easier to find a cave that is worth exploring
• Borders between new and old surface terrain after version updates look more natural
• fixed subbiomes spawning outside their parent biome

New Biomes

• crying caves

• linux versions with older glibc are supported by the release binary
• progress on the Vulkan rewrite
• fixed client lag spikes on bulk block updates
• block entities now use mod:name ids
• item migrations were fixed, iron ingots from before version 0.2.0 can be stacked with the migrated chisel iron
• fixed random teleportation issue in the physics code
