Thesis 1.0.1 fixes a compatibility issue with the WordPress 2.6 admin interface that prevented the options panel from working properly. The only theme file that has changed for this intermediate release is options.php, which you can find here:
/thesis/lib/classes/options.php
For the simplest upgrade possible, simply replace that file, be sure to hit refresh on your options panel, and you should be good to go!
