This was an admittedly minor bug, but one that probably shouldn’t have QA regardless. In FF/IE, there’s a small border around images that double as links where there shouldn’t be.
This bug has been fixed, and the latest version can be downloaded here.
Another bug was found. This one affected photo posts. While updating the theme for release, I changed from 400px-wide to 500px-wide images and that caused a minor spacing issue.
As far as I can tell, the bug only affected Internet Explorer. The bug has been fixed, and and updated version is available for downloading.
