Landing video is up, didn't see anyone else post it yet:

Apparently the fins got stuck at a steep angle when the hydraulic fluid ran out, and the engine gimbal couldn't compensate for it and still decelerate enough to land softly.
Unfortunately, from the video, it looks like there won't be many pieces left that are large enough to determine whether it really will be reusable when they land it in one piece. Hopefully next time it will work.
Wasn't this also the first time they did a boostback manoeuvre where it turns around and heads back toward Florida? I think the previous attempts just fell into the sea wherever it was heading.
Edit: here you go, this is how it's supposed to work:
