! The recent Wess rewrite (adding the ability to mix regular CSS with indented CSS) broke the @replace feature. (Class-CSS.php)
! I visited Wedge.org on an old Powerbook using Safari 5.1, and it couldn't get to use the CSS, so I'm guessing Safari 5.1 Mac != Safari 5.1 Windows, and Apple, you suck. So I'm extending the maximum version to 5.1 rather than 5.0, and I'd like for anyone with a more recent Mac to confirm that Wedge.org works fine on Safari 6. I think Safari 7 is safe.
