Hunting and taming. Domesticated animals will keep you occupied for quite some time and will provide you with nice stuff.

Righteo! I guess hunting is next on the list. A mixture of UA and for boars/bears the old "surround em With boats" trick!

You can create stockpiles now, which are little piles of different items. You can stockpile boards, blocks, stick, stones, metal, bricks, clay, and much, MUCH more. Just pick something up with left-click and right-click it onto the ground to start one.

Various items, when dropped, do special things. If you drop a itsy bitsy spider on the ground, it'll start running around. If you drop a barkboat in the water, it'll float around. Stuff like webs and seeds don't disappear anymore, you can see and pick it up from the ground. (Dropping powders still makes them disappear.)
