Changelog v0.11.1

v0.11.1

Released 5th August 2026.

This version includes protocol support for 1.26.40, adds End crystals, custom dimensions and concurrent chunk loading, and reworks the explosion API around world.ExplosionSource.

Changes

block

• Implemented End crystals
• Added cinnabar and sulfur building block sets, including bricks, polished variants, slabs, stairs and walls
• Blast resistance and explosion behaviour now match vanilla
• Reduced explosion block selection overhead

cube

• Bounding boxes are now generic over float32 and float64

entity

• Added support for the AlwaysShowNameTag data flag
• Reduced movement collision scan overhead

item

• Moved the item NBT codec out of internal/nbtconv into server/item, so importing server/item on its own no longer depends on another package pulling the codec into the binary

player

• Added the HandleSetOnFire player handler, receiving the duration the player is set on fire for
• The airborne mining penalty is no longer applied to flying players

server

• Replaced explosion positions with a world.ExplosionSource, giving handlers the originating block or entity alongside the position, and deriving radius, item drop chance and damage from a single size
• config.Allow is now passed to gophertunnel for earlier handling, removing redundant resource pack serving

session

• The player's build platform is now included in the player list

world

• Added concurrent chunk loading, generation and light calculations, moving disk reads, generation and lighting off the transaction goroutine:
  • Added Config.ChunkLoadWorkers (default 1) to generate multiple chunks in parallel, requiring a concurrency-safe generator
  • Provider calls are serialised internally, so providers need not be concurrency-safe
• Added a custom dimension registry via RegisterDimension(), accepting IDs between 1000 and 65535
• Added the HandlePortalCreate and HandlePortalActivate world handlers for portal lifecycle events

world/sound

• Added sound.Custom for playing sounds defined by a resource pack

Breaking Changes

world

• Loader.Load is now asynchronous: chunks appear after it returns
• Tx.Light returns 0 for unloaded chunks instead of generating them
• World.HighestLightBlocker is now off-owner only: use Tx.HighestLightBlocker inside a transaction
• Explosion handlers and Explodable now take a world.ExplosionSource instead of a position, and ExplosionConfig is no longer passed to Explodable
• Handler gained HandlePortalCreate and HandlePortalActivate, which custom handlers embedding NopHandler inherit

cube

• cube.BBox is now generic, so code naming the type explicitly needs a type parameter

item

• nbtconv.WriteItem and nbtconv.MapItem moved to server/item

Bug Fixes

block

• Fixed panic when calling BreakInfo() on unplaced smelter blocks
• Fixed panic when decoding pot sherd NBT
• Fixed outdated custom block components
• Custom block components now send destroy seconds instead of hardness
• Hopper cooldown ticks are no longer broadcast as block changes

server

• Fixed End crystal fire and placement parity with vanilla
• Simplified and fixed End crystal explosion logic
• Empty custom item entries are no longer sent

world

• Fixed the outermost ring of the load radius being dropped when populating the load queue
• Fixed chunk distance overflowing int32 for far-apart positions, such as long teleports
