New revision 4.5 of the HALCON 9.0 / 10 SiliconSoftware interface released which fixes a thread safety problem in the operators grab_image and grab_image_async that could occur if a pending grab was aborted via the 'do_abort_grab' parameter of set_framegrabber_param. Furthermore, the return value has been corrected in case that a pending grab was aborted by the user (registered customers can download it here).
