Blocks

 * Trapdoors, buttons and pressure plates made from all six types of wood.
 * A pumpkin block, without the face. The previous pumpkin block has been renamed "Carved Pumpkin".

 * Multiple vines facing different directions, including on the bottom of blocks, can now be placed in the same block space.

Items
