Aventurine has added a Coastal Runner, which is the fastest ship in the game. It's a good thing it's so quick, too, because it has no cannons. There's also the Pinnace, a warship featuring three cannons. Harbors and shipyards are also available to build in clan holdings as of the patch.
There's more, including plenty of gameplay tweaks and general fixes. The Darkfall forums has a listing of the full patch notes.
