* added ED_SCRIPT_OT_run_pyfile that takes a filename argument. * RNA_property_string_set didn't add a value to ID props if the prop wasnt there (like ints, floats and bools do) * bpy_operator.c - raise an error when unknown keyword args are passed to any operator . Examples of bpy operator api... bpyoperator.ED_VIEW3D_OT_viewhome(center=1) bpyoperator.ED_SCR_OT_frame_offset(delta=10) bpyoperator.ED_VIEW3D_OT_make_parent(type='OBJECT') At the moment there is no way to stop the operators .invoke() function from running so ED_VIEW3D_OT_make_parent still opens the menu even though it doesn't need to.
