Hurray! Thematic 1.01 is now available via the WordPress Theme Repository. There are a lot of changes in this release. A list of changes can be found in the read me.txt in the root of the theme.
The support forums are open if you need them. We are transitioning support from ThemeShaper to ThematicTheme so please open or move your support requests to the forums here. If you feel the upgrade has adversely affected your site and you need to temporarily revert back to Thematic 0.9.7.7 while you sort out the issue before finally upgrading to 1.0.1 you can find the previous release here.
