Major changes to the .info array for css support. Also added library support for adding js and css in a bulk. Added caching to the css and library registry. Added a default styles.css to every starterkit.

Renamed a few of the grid files (I must've been drunk yesterday) and implemented some advanced Delta stuff into Alpha

Improved the alpha theme registry and made it 100% rock solid (even when not currently being the active theme or while on the theme-settings page).

Added alpha_alter as a convenient method for invoking drupal_alter on the theme layer. Added support for extending the alpha_settings array via alpha_alter. Added 'Formalize' by Nathan Smith into the Omega base theme (toggleable via the theme-settings).

All blocks (debugging, etc.) are now added via hook_block_list_alter / Cleaned up the code once more / Added breadcrumbs CSS.

Even more tweaking. Also added support for conditional stylesheets (both, for responsive styles and for normal optional styles)

Made the debugging blocks depend on the 'Access by role' setting that the debugging grid uses too and improved the settings array and preprocessing

Added support for additional fluid grids / Added functionality to hide certain page elements (like site-name, site-title, etc.) via CSS (element-invisible) / Tweaked the region--branding.tpl.php slightly / Changed the names of the grid.css files to include the name of the grid.

Added the possibility to add the debugging blocks only to regions that would get displayed otherwise.

Added the ability to toggle core elements like , , etc. (in the same way that this is already possible with stuff like ). This will be necesary in situations where the user wants to display that stuff in a block. We will provide functionality for blocks like that with the upcoming 'Omega UI' module.

Added a feature that allows regions and zones to be rendered even if they are completly empty. This can be activated in the Region and Zone settings.

Removed the comment on alpha_theme_get_setting that said that we needed to change the function in order to make it work with Delta... Because THATS NOT TRUE ANYMORE - Delta works independently now.

Brought back 'enabled' for zones and regions. 'Enabled' is now being automatically determined based on wether the corresponding zone / section exists or not.

Changed the section / zone configuration in the theme-settings UI. Zones can no longer be disabled, instead they can be moved out of regions. Zones dont have their own vertical tab anymore, instead they are being configured 'inline' inside of the section configuration.

Improved the section wrappers in the theme settings UI and added some wrapper functions in the omega.inc

Fixed a bug in the hook registry (was completly broken) and removed the fake blocks (those will be part of omega ui)

Started to add comments and documentation to alpha.inc - Fixed some minor 'bug' while reading through the code.

Added support for disabling / excluding core, contrib module and theme stylesheets[] definitions via the Omega / Alpha theme settings

Added support for all Alpha 'fake blocks' / Added page title in region--content.tpl.php in Omega / Moved all tpl.php files in Alpha and Omega from  and  to  (drupal_attributes) / Added a few more &drupal_static's to the functions in alpha.inc / Improved alpha_include_grid() / Some preprocess & process tweaks

updating branding block to respect visibility settings for site name and slogan via element-invisible class

adding default text.css to Omega, setting up Alpha with a first pass at rendering the faked branding block; needs review & refining

variable_get was being called 10s of times in alpha_invoke on the theme load. Saving  as a static variable reduces the variable_get calls down to one on theme load.
