+v1.11
+-----
+ - Asset URLs can be obtained, see "Getting asset paths / urls".
+ - Casset::add_group() has been re-implemented.
+ - Callbacks now exist: You can use these to process js/css files after they're loaded, but before they're cached. Allows use of SASS, Coffeescript, etc.
+ - Exception now thrown if someone attempts to define a group that already exists.
+ - Group options are now specified using array syntax, instead of separate function arguments.
+ - Option to inline groups moved from Caset::render() to when the group's defined.
+ - Option to add attributes to a group's tag moved from Casset::render() to when the group's defined.
+ - Add dependencies between groups. Rendering a group will automatically render its dependencies.
+ - New functions to allow changing of group options on-the-fly.
