I see that a 2.0 Gold-compatible version has been released. I've already upgraded to it, but there's one bug I noticed: The box where you type your posts stretches horizontally when your text reaches the end of it instead of going to a new line. I checked the other themes that are installed on my board, and the box works correctly on those themes.
Admittedly, it's more of an annoyance than anything, as posting does work. Even so, I want it fixed, and some help in doing so is highly appreciated.
EDIT: Managed to fix it on my own. If any of you have the same problem, all you have to do is add a width property to the following line in index.css:
#quickReplyOptions form textarea
margin: 0.25em 0 1em 0;
