Many bug fixes and better compatibility with newer versions of WordPress.
Updated all default color schemes that come packaged with the plugin. (You will need to delete all old versions of the default schemes and then deactivate and reactivate the plugin in order to get the new versions)
Added a new "Orange" default color scheme.
Added minified versions of all admin scripts and styles used by the plugin to improve speed. Can be set to use non-minified versions by changing the EACS_DEBUG flag in the main plugin file.
Went back to prefixed function names instead of PHP 5.3 namespaces because of many complaints. Maybe we can try again some time in the future.
Version 4.0 is a complete rewrite from the ground up. Everything has been restructured and improved.
Schemes have been moved from the file system to the database to prevent various file permissions issues the old versions suffered from.
Simplified a lot of the code thanks to using a custom post type in the background.
Old scheme exports are not compatible with the new version. However, a simple copy-paste procedure from the old scheme file into the Add Scheme page should work fine.
Fixed (hopefully) the image display problems in the lower preview pane when adding/editing a color scheme
Fixed a bug in the last modified times function
Added a new Preview function which opens a preview of the selected color scheme in a lightbox
Added some more in-depth permissions functionality
Added the ability for the primary colors to actually affect the color scheme
Added the ability to set a default color scheme which will affect all new users
Added the ability to force a certain color scheme on all users regardless of what they choose
Updated the included readme, screenshot, and .POT file to include the new changes
