I have just uploaded the latest version of Ground Floor to the WordPress.org Theme repository. Most of the updates were focused on cleaning up the CSS file as well as adding the two footer functions: bns_dynamic_copyright (version 1.3), and bns_theme_version (version 1.2.1). Here is the lastest changelog:
