Chests were added with the other wood stuffs. There are the normal ones and trapped chest, which give off a redstone signal if opened. Both can be made into a double chest to store more items. You can put two different kinds of chests next to each other, single or double, like how you can with the chests from the IDT mod.
Fixed chests removing items if you went out of the chunk and back in. (I think this was a bug, haven't been able to replicate it, so maybe I fixed it?)
