Hello, 14w04a has added new AI to villagers, and i have made this post to help people find out what the changes are and what uses they can have.
I currently know a little on the subject, but im sure there i more than i know:
Farmers-
*now harvest and picks up wheat
*now plant wheat
*now make bread? (ive only heard of this, cant confirm it)
Butcher-
*picks up wheat, doesnt seem to use it for animal guiding or breeding yet.
If you know anymore about the new AI, or any uses for it, please post them
