Changelog - 2026-06-20

Combat, Mobs, and Entities

  • Combat Overhaul: Added full combat system with sword/bow/axe attacks, knockback, critical hits, and attack cooldown
  • New Mobs: Added creepers (explosion mechanics), skeletons (ranged AI + held items), spiders (raycasting/climbing), and improved fish behavior
  • Mob AI Improvements: Mobs now look around, pathfinding optimizations, villager profession/trading improvements, and villager culling fixes
  • Shields: Shield blocking mechanics
  • Drowning/Oxygen: Added oxygen bar and drowning damage for underwater players
  • Item Entities: Items now drop as entities in the world with pickup animation

Blocks, Items, and Interactions

  • New Containers: Added barrels (directional opening/closing) and ender chests with per-player inventory
  • Crafting & Items: Improved crafting system with new recipes, furnace crafting fixes, item durability, and loot tables for villages
  • Beds: Bed placement with proper head/foot orientation, sleeping mechanics, and bed explosion in Nether/End
  • Village Trading: Villager professions with emerald trading and GUI support
  • Special Block Behavior: Added NBT data loading/parsing, Ladders (climbable + impalement damage), Glass, sapling drop rate fixes, and expanded special block state handling
  • World Format: Migrated world save format to structured JSON (world.json), supporting dynamic block change limits and better serialization
  • XP Orbs: Experience orbs drop from mobs/ores with pickup and UI
  • Difficulty Settings: Difficulty now configurable in server.conf (peaceful/easy/normal/hard) with gameplay effects
  • Explosions: Entity explosion system (creepers, beds, TNT) with block damage and physics push

Sound

  • Sound System: Added player footstep sounds, block interaction sounds, shield sounds, damage sounds, and entity ambient sounds

Performance and Optimization

  • Chunk Memory Optimization: Massive reduction in chunk memory usage (~75% reduction) with sparse section storage, uniform-block optimizations, and dynamic allocation
  • World Generation Speed: Huge performance improvements in chunk generation (~6.6× faster) via cave/ore density grids, structure cell caches, y-range guards, and lookup tables
  • CPU Usage: Drastically reduced CPU usage in hot paths - optimized pathfinding, fluid processing, villager AI, and general tick performance; added broadcast_all_movement and scale_movement_updates config options
  • Dynamic Block Limits: Added infinite_block_changes config option for unlimited player edits with dynamic memory allocation

Infrastructure and Tooling

  • Developer Documentation: Added comprehensive DEVELOPER.md covering architecture, thread model, packet flow, chunk pipeline, and extension guides
  • LLM Context File: Added LLM_REPO_DOCS.md for AI-assisted development with canonical codebase overview
  • Missing Features Tracker: Added MISSING_FEATURES.md with priority-ordered unimplemented features
  • Benchmarking Tools: Added bench_worldgen.c and bench_worldgen.sh for world generation performance benchmarking
  • Rebuild Script: Added rebuild.sh - one-command full rebuild from scratch (download server.jar → dump registries → generate code → compile)
  • Village Template Generation: Added build_village_templates.js - generates village building NBT structures from vanilla data
  • Packet Decoding: Added packet decoding helpers for easier debugging and development
  • Agent Skills: Added Zed agent skills for project context and task guidance
  • Config Expansion: New server.conf options: difficulty, infinite_block_changes, sync_blocks_on_interval, scale_movement_updates, enable_pickup_animation, enable_cactus_damage

Build System

  • Code Generation: Enhanced build_registries.js with NBT extraction and expanded block type coverage
  • Extraction Tools: Added decode_tags.py for vanilla data tag decoding
  • Clean Build Support: Build system improvements for reliable clean builds across all targets

Documentation

  • README: Updated with new build instructions for Debian/Ubuntu and Arch Linux dependencies, cross-compilation details, and quick-start guide
  • index.html: Updated project landing page with new screenshots and descriptions
  • Network Graph: Added ASCII infrastructure graph to README
