! Wess already supports backface-visibility's prefix handling. (common.css)
- Removed tabindex helpers from sel_* select boxes in the post editor. Why, should you ask..? Because they're in the way. If you switch from title to body with the tab key, you'll end up hitting at least two barely used select boxes first, and it's a PITA. Seriously, I'm not going to help 'accessibility' by allowing easier access to features that get in the way of actual productivity. If you customize font faces for all your posts, you have a problem. (Class-Editor.php)
+ Added a new helper function, strhas(), which is the equivalent of strpos() !== false, but also supports arrays of strings, to avoid multiple strpos tests, or even worse -- preg_match tests, which are so much slower than strpos calls (actually, the more calls, the faster strpos gets.) (Subs.php)

* Replaced some obvious culprits with strhas. I'm sure you'll agree that it rocks, at this point. Or you won't care. Which is more likely. (Class-CSS.php, Class-System.php, Login.php, Login2.php, Security.php)
