Distant Horizons: A Level of Detail mod

Highlights:

• Up API version 4.1.0 -> 5.0.0
• Loading pre-existing LODs improved by about 5x
• Importing pre-existing chunks improved by about 20x
• Decreased new database size by about 40% (existing databases will be unaffected)

Full Changelog

Additions:

• Added MC 1.21.11 support
• Add far clip fading
  • DH clouds should fade seamlessly into the horizon instead of having a sharp cut-off
  • disabled on lower graphics configs
• Auto disable vanilla clouds and MC chunk fading (1.21.11 only) in the vanilla config when first starting DH
  • this can be disabled in the graphics config

Improvements:

• Improved occlusion culling on saved LOD data
  • thanks Scaevolus
• Massively improved importing existing worlds speed (roughly a 20x speed improvement)
• Optimize biome color handling
• Improve LOD loading speed (roughly a 5x speed improvement)
• Improve compressor speed
  • Replace Z_STD stream compression with block compression (6x speed improvement for reading, 3x speed improvment for writing)
• Reduce database size
  • Add var int encoding
    • thanks Scaevolus
• Speed up world shutdown time
• Improve logging/messaging for corrupted databases

Changes:

• Up API version 4.1.0 -> 5.0.0
• Sepearted file/chat log configs
• Replace Z_STD stream compression with block compression
• Change DB format version 1 -> 2
  • adjacent data is no longer stored in the main data BLOB, but in 4 different columns, which allows for a drastic LOD loading speed improvement
• Dont render snow as an additional block above the ground
  • trees will no longer be an extra block thick and snowly plains wont have a weird extra block when walking on them
• Allow world gen limiting (IE max radius around a given X/Z chunk pos) on singleplayer
• Remove some unneeded log messages
• Add thread pool priority config
  • Formerly DH used priority 0 (lowest possible), now the priority is 5 (java default)
  • Setting this to 1 higher than C2MEs thread priority may prevent holes when using DH with Chunky+C2ME

Bug Fixes:

• Fix internal server generation (IE: Full - Generate Chunks) not generting chunks
• Fix changing render distance causing issues with Iris
  • LodRenderer is now a singleton and the OpenGL IDs provided are stable across config and level changes
• Fix generating chunks on pre-generated worlds
  • this may cause a new issue where incomplete chunks are shown (IE all stone-gray chunks where only SURFACE was generated), but this is preferible
• Fix a crash with Reploy mod during shutdown
• Fix Iris not setting face culling in the MC state manager
• Fix biome blending causing grids and/or incorrect colors
• Fix /dh command being deleted after reloading
  • thanks Acuadragon100
• Fix world gen stopping when MC is paused
  • DH now uses local timers instead of MC server/client ticks
• Fix some Iris issues on NeoForge
  • Oculus will still have these issues
• Fix handling of empty server keys
• fix debug LOD only mode when transparency is disabled

Removals:

• Compression config option
  • Now the only compression option is Z_STD_BLOCK, which is nearly as compression efficient as LZMA (without causing the whole PC to stutter due to RAM bandwidth saturation) and as fast as LZ4.
