CC revised class list, the full list can be found on the 4th page of the CC dev discussion

Minecraft: getting the ChunkCubes around the player to preload when loading a new world (or dimension); dimension-jumping y-shifting (to make y like x&z); a few misc methods.

BiomeTerrainDefaultFileWriter: writes the default terrain file

Chunk: edited to use a CubeArray of ChunkCubes. Leave all the methods, but re-route them to use ChunkCubes.

ChunkBlockMap: edited to be able to use CubeBlockDatas. This might not still need to be edited.

ChunkCube: added ChunkCubes.

ChunkCubeAir: added air versions of ChunkCubes, which use much less memory.

ChunkCubeCoord: added coordinates for ChunkCubes.

ChunkLoader: edited to fix a ("level.setInteger("xPos", i);") bug; to add method stubs (since ChunkCubes are never saved in pre-Scaevolus format); to create CC versions of storeCubeInCompound, storeChunkInCompound, and loadCubeIntoWorldFromCompound; to create loadChunkIntoWorldFromCompound methods for loading (potentially a range) chunk data from any needed format; to add loadEntities, loadTileEntities, loadTileTicks, and getBlocksHeightShift methods for general use; and to add getSaveDir() (basically a method for my convenience in determining the current save dir). NOTE: this handles (or handled) 4096IDs item ID shifting

ChunkProvider: edited to support ChunkCube methods, as well as Chunk methods

ChunkProviderClient: edited to support ChunkCube methods, as well as Chunk methods

ChunkProviderGenerateBase: added to create method stubs for the methods that are basically functionless in generating ChunkProviders

ChunkProviderGenerate: edited to support generating ChunkCubes, as well as just Chunks; added higher-terrain functionality

ChunkProviderLoadOrGenerate: this does not appear to be used anywhere in vanilla Minecraft code. Thus, I just edited it to make it compile.
//I think I might have edited one or two components - not sure which, though I think ComponentVillage.java was, if nothing else - to remove height/depth hardcoded limits

CubeArray: Added to store ChunkCubes, without having to allocate an array of (MaxHeight/16) ChunkCube pointers every time a Chunk was created. They usually only have to allocate an array of 50 ChunkCube pointers.

CubeArrayIterator: Added to iterate through CubeArrays.

CubeBlockData12Bit: Added to store ChunkCube data (for old-style 256IDs saves).

*CubeBlockData16Bit: Added to store ChunkCube data (for Robinton-4096IDs saves).

*CubeBlockData: Added. This class had 2 versions, which could be swapped to switch from CC-regular to CC-4096IDs. One version was a subclass of CubeBlockData12Bit, the other of CubeBlockData16Bit.

CubeBlockDataDelayedInit: Added for ChunkCubeAirs.

CubePopulatorModBase: Added a basic default (do-nothing) implementation of the ICubePopulator interface, with all methods overridable.

*CubicChunksHooks: Added a class to load and store data on which other mods were currently installed.

EmptyCube: Added always-empty version of ChunkCube. Very usefull for whatever's above the sky, and below the core.

Entity: slightly edited to remove a hard-coded depth limit. NOTE: I've put in a hook for this in my new Magic mod.

EntityRenderer: edited to fix hardcoded y-values.

*GameSettings: edited to add "LimitYRenderOnFar" and "use74sFarViewMod" settings.

*HeightMap: added class to store Height Maps. I don't think I ever actually used this.

IChunkLoader: edited to add ChunkCube methods.

IChunkProvider: edited to add ChunkCube methods.

ICubeBlockData: added as an interface for anything storing Cube Block Data (IDs & MDs but not light).

ICubePopulator: added as the base interface for any mod that populates terrain. ChunkProvider automatically queries any ModLoader loaded mod classes that implement ICubePopulator whenever generating or populating a ChunkCube.

ItemBlock: edited to remove hardcoded y=128/y=256 limit.

*ItemMap: edited to support ChunkCubes. May no longer need to edit.

MapGenBase: edited to add cubic generation methods.

mod_CubicChunks: added to display CubicChunks info with ModLoader.

NBTBase: edited to support NBTTagShortArrays.

NBTTagCompound: edited to support NBTTagShortArrays and a few helpful methods.

NBTTagShortArray: added to support saving short[].

NibbleArray: edited to support delayed-init NibbleArrays.

NibbleArrayDelayedInit: added for ChunkCubeAirs.

Packet6SpawnPosition: possibly edited to support full y-range.

Packet14BlockDig: edited to support full y-range.
Packet15Place: edited to support full y-range.
Packet17Sleep: probably edited to support full y-range.
Packet24MobSpawn: possibly edited to support full y-range.
Packet50PreChunk: edited to support Cubic Chunks.
Packet51MapChunk: edited to support Cubic Chunks.
Packet52MultiBlockChange: edited to support full y-range.
Packet53BlockChange: edited to support full y-range.
Packet61DoorChange: edited to support full y-range.
Packet130UpdateSign: edited to support full y-range.

RegionFile: edited to support different sector sizes.

RegionFileCache: edited to support different RegionFile types for Chunks and ChunkCubes.

RegionFileLarge: added to support saving Chunks and loading old RegionFiles.

RegionFileSmall: added to support saving ChunkCubes.

RenderGlobal: edited to support rendering full y-range.

ThreadedFileIOBase: edited to dramatically speed up saving during save-and-quit.

World: drastically edited to allow use of ChunkCubes, and to remove hard-coded height constraints.

WorldClient: slightly edited to allow use of ChunkCubes, and to remove hard-coded height constraints.
