The last time I submitted a version it got stuck in the review queue for 2 weeks. So this time I am releasing a patch for the issues identified in 3.9.4. Please note that each of these issues is minor and only occurs in a less used scenario (rotating headers, static tabbed sidebar with custom tab headers and tall site footers). People who haven’t faced issues don’t need the patch.
You can get the patch from the Google Code page. I have deliberately left the version number at 3.9.4, so that you can update it directly from WP when they approve it there. For instructions on how to install the patch, see the “Having Installation Trouble” section.
