Highlights Classes can now define operator methods (operator overloading) e.g.: “==”, “!=”, “>” … See chapter Operator Methods. Class events can be used inside a class (similar to the object-oriented panel #event functions - ) See chapter Class Event Functions. Expressions can now be chained via the “dot” notation. See chapter Dot Notation. New childPanel (dyn_shape) function returns the module/panel names currently running in a UI manager. See chapter "childPanels".
