It appears the sole purpose of this update is to remove all "unauthorised" installed software and attempt to close any bug that might be used to reinstall them. This includes updating the boot loader. However Nintendo's update code is not as robust as that of the Bootmii installer, thus if the update does not go smoothly your wii will be bricked (regardless of if you have unauthorised software or not). Team tweezers have already released an updated installer to give you a version of the Homebrew Channel that will survive Nintendo's update, however your bootloader can not be protected."
