The Alpha4 release of Omega for Drupal 7 includes bug fixes for the local task tabs rendering properly, and also includes a new feature which allows front and internal pages to have different options for display on the main content/sidebars.

The focus of this release was stabilization and various bug fixes. Referenced taxonomy terms are now exported and synchronized with the profile field options. Further profile taxonomy integrate nicely with profile_checkboxes, Views, ApacheSolr etc.:
