You can (in theory) download a new hashcat release and replace the version bundled with the gui. The GUI won't have new options or notice changes in how certain command line options work, so for releases that only have bug fixes or new features that would be fine, but doing this with the most recent release (merge of regular oclHc and oclHc-plus etc.) will cause random problems, replacing CPU hashcat and -lite should work fine as those only had non-invasive changes lately.
I'll try to get a new GUI release out to testers this weekend, if no problems arise perhaps even an official update on sunday already.
