 * Request forgery protection has been tightened up to apply to HTML-formatted content requests only.
 * Polymorphic URLs behave more sensibly if a passed parameter is nil. For example, calling `polymorphic_path([@project, @date, @area])` with a nil date will give you `project_area_path`.

When templates are collected in the template resolver file paths they only include the template language extension and not the mime type.
