    Version 1.49.91
    
    - Deprecation: The private "__name__" property on Lang.Class instances is
      now discouraged. Code should not have been using this anyway, but if it did
      then it should use the "name" property on the class (this.__name__ should
      become this.constructor.name), which is compatible with ES6 classes.
    
    - Closed bugs:
    
      * Use ES6 classes [#785652, Philip Chimento]
      * A few fixes for stack traces and error reporting [#786183, Philip Chimento]
      * /proc/self/stat is read for every frame if GC was not needed [#786017,
        Benjamin Berg]
    
    - Build fix [Philip Chimento]
