- CPView and subclasses support multiple-value hidden bindings. - CPControl and subclasses support multiple-value enabled bindings. - CPWindow and CPBox support multiple-value title with pattern bindings. - CPButton supports multiple argument + target bindings. - CPImageView and CPTextField support multiple-value editable bindings. - CPMenuItem supports multiple-value enabled bindings. - Fixed bugs in CPObjectController with simple collection operators. - CPColorWell uses black as the placeholder color. - Runtime object attributes from a cib are applied as they are read, not deferred. - NSNumberFormatter now reads the number style from the xib. - Normalized some parameter names. - Formatting. - Test app for all binding types.
