Blocks
These can also be called "Block IDs." These values apply to both inventory items and to blocks placed in the world. Bold entries are not available in Alpha and italics entries are not available in Classic. Entries marked with a D require additional data to fully define the block in an Alpha world.

Saplings
0x0 is a freshly planted sapling. The data value is incremented at random intervals. When it becomes 15, a new tree is created in its place.

0x0 is a full block. Water goes up to 0x7, Lava can only go up to 0x3. If bit 0x8 is set, this liquid is "falling" and only spreads downward.
Soil
0x0 is dry land, 0x1-0x8 are increasing levels of wetness. The wetness value depends on how far the block is away from water.
Crops
Crops grow from 0x0 to 0x7 (not pictured).
