For users

• Support MC 1.21.8.
• Fixed bamboo spawning on beaches.
• Probably fixed sinytra connector compatibility again.
• Fixed tropical fish not spawning anywhere.
• By small but very loud demand, made it impossible to be stranded on the nether roof in Big Globe worlds.

For data pack developers

• Fixed scripts calling setBlockState() with a null block state causing problems.
• Implemented perlin derivative grids.
  • Min and max values of perlin derivative grids are NOT implemented. Thankfully, not much uses those as far as I can tell. Seems to just be rock layers. So like... don't use perlin derivative grids for rock layers. Regular perlin grids are fine.
