+* Added that controllers will now search for a layout in $template_root/layouts/$controller_name.r(html|xml), so PostsController will look

 * Added FormHelper#radio_button to work with radio buttons like its already possible with check boxes [Michael Koziarski]
 
 * Added TemplateError#backtrace that makes it much easier to debug template errors from unit and functional tests
