Features:

• Improve water particle water collision detection:
  • Accounts for fluid height.
  • Allows water particles to survive in any blocks that can create them (entities swimming in blocks that return true for isAABBInsideMaterial, but aren't a fluid, for example).
• New config setting that allows FluidState redstone behavior to be disabled.

Bug Fixes:

• Block material entity acceleration now only caches chunks as-needed (probably fixes #290).
• Fix a couple very rare crashes related to fluid entity collision.
• Fix a crash that would happen if a mod attempted to render a fluid block without a world loaded.
• Fix a possible crash related to MutableBlockPos multi-threading (probably fixes the 1st half of #289).
• Fix fluid collision not working at all for very small fluid heights.
• Much better fix for MC-2591 (it actually works now).
• Rewrite the FluidState redstone logic implementation. This fixes many (maybe all?) modded redstone-related conflicts!

Compatibility Fixes:

• Cleanroom Mod Loader:
  • Fix a strange crash with Cleanroom on mobile (fixes #292).
  • Should no longer require the Fugue mod for Fluidlogged API to run.
• Dynamic Surroundings:
  • Account for FluidStates when checking fluid color for the position.
  • Add FluidState support for Dynamic Surroundings' underwater breathing effect.
  • Fluid drop particles no longer phase through FluidStates.
  • Now plays all ambient/random block effects for FluidStates!
  • Rain drop particles no longer phase through FluidStates.
  • Rain drop particles now create water ripples on FluidStates.
  • Steam jet effect now accounts for FluidStates when counting the amount of surrounding "hot" blocks.
  • Water splash jet effect is now FluidState-sensitive.
• Galacticraft:
  • Fix a crash when fire checks whether certain Galacticraft fluids are flammable (fixes #291).
  • Make Galacticraft's fluid drip particle account for FluidStates during its collision check.
• Immersive Engineering:
  • Wires (and other IE-like wires from other addons like Industrial Wires) now correctly trigger electrocuted damage + knockback with this mod installed (fixes #286).
• NuclearCraft:
  • Make all NuclearCraft source gas fluid blocks only vaporize their FluidState while fluidlogged instead of the whole block (fixes 2nd half of #289).
• OreLib:
  • Allow OreLib's IBlockAccessEx class to read FluidStates. This fix was originally part of my Subaquatic mod, but I'm moving it so it can be updated here as necessary.
• Tropicraft:
  • Allow Tropicraft's fish hook entity to account for FluidStates when deciding which blocks to play splash effects for.

API Changes:

• Blocks without a material of lava are automatically marked as entity flammable if they return true for Block.isAABBInsideMaterial(world, pos, aabb, Material.LAVA).
• Buckets now correctly pass the player into FluidUtil.tryPlaceFluid. This fixes a very minor unintentional code behavioral difference between forge and this mod.
• Fix a bad return value in PluginWorld.Hooks.setBlockToAir (client now returns true if a fluid is at the position instead of false). This makes the client & server return the same value.
• New api.world.ICubeData interface:
  • Represents a 16x16x16 section of block data, without a reliance on using Chunks.
  • New FluidloggedUtils methods that accept ICubeData instead of a chunk. The old chunk-based methods still exist for backwards compatibility.
• New api.world.ICubeDataProvider interface:
  • Allows custom IBlockAccess implementations to supply ICubeData.
• New api.world.IFluidEventListener interface:
  • Allows code to be executed when a FluidState changes somewhere in the world.
  • This is intended to be used the same way as IWorldEventListener.notifyBlockUpdate.
  • IFluidloggable.onFluidChange, Block.onBlockAdded, and Block.neighborChanged should still be enough for most cases.
