     * Added sticky table headers.
     * Check for clean URL support automatically with JavaScript.
     * Removed default/settings.php. Instead the installer will create it from default.settings.php.
+    * Made it possible to configure your own date formats.
 - Theme system:
     * Added .info files to themes and made it easier to specify regions and features.
     * Added theme registry: modules can directly provide .tpl.php files for their themes without having to create theme_ functions.
