Added a brand-new Drush command called "drush omega-wizard" (drush owiz) that allows users to create subthemes through a Drush wizard. This allows people who do not know the syntax of "drush omega-subtheme" to conveniently generate themes with the same power that the "drush omega-subtheme" command offers.
Fixed a bug in omega_discovery() that caused sub-themes to not be able to override base-theme definitions.
Quick follow-up for 7.x-4.0-alpha3 that fixes a problem with compatibility checks for extension dependencies making it work with development versions of modules now as well. Also, it appears that the theme function include files were named incorrectly all the time.
This beta release fixes several known issues, and adds several new features.
Updates to beta2 from beta1 should be painless. At the most, if you have your content region ordered visually differently than the HTML order, you may need to adjust some settings in the UI to get them to render properly again.
The beta1 release of Omega marks the next generation in Drupal theming with responsive layouts, customizable grids all based on 960.gs standards, advanced theme caching with drastically improved performance, more solid debugging, and more features that can be possibly counted here.
The 3.x version is still highly undocumented, and the documentation at http://himer.us/omega960 still relates to the 2.x version of Omega.
Fixes for various minor issues.
IE support (fallback) for IE 6, 7 and 8 which do not respect media queries for responsive layouts.
Update .info defaults for all core and starterkit themes (check your .info and/or theme settings to ensure everything is checked/placed appropriately)
This should be the last "major" update prior to a beta release.
