0.4.0

Voxels

• Face data now tracks its source per face, not per cell (fixes stale light/face data on refresh)
• Fixed vertex grid cracks at section edges
• Batch uploads reuse one buffer and fence instead of allocating each time (faster)
• Face data shrunk from 18,432 to 16,128 bytes per slot
• Model and sprite reads split from GPU upload lifetime
• Chunks now queue a harvest on arrival, so missed sections fill in without waiting on camera move

Water

• Water prepass now draws for every water tier, not just reflection mode
• Prepass targets no longer depend on the draw gate
• Fixed cloud shadows and fluid column height scans

World data for packs

• Packs can read the world's day count and day fraction
• Day values crossfade over real time instead of cutting at the day boundary
• Wider climate data: temperature, downfall, biome tags
• Nether fog options added
• End portal and gateway get their own slot
• Glass refraction strength exposed to terrain

Graph engine

• Compute results reuse across frames when inputs match
• Independent passes can overlap instead of waiting in strict order
• New consolidate pass for reading several targets through one array texture
• Passes can be gated per dimension
• 3D volume textures supported for compute passes

Debug and profiling

• GPU/CPU timings tagged by frame ID
• Profiler overlay can filter by pass, counter, or slowest only
• Can dump one frame's raw pass inputs/outputs

Fixes

• Deferred slot reporting fixed for forward and particle paths
• Linear-filter check no longer looks at compute-only images
• Tests now pin field order in u_Globals, not just total size

Docs

• Fixed stale mixin and test counts in AGENTS.md
• Fixed u_Globals byte size in ARCHITECTURE.md
