I'm finally going to get around to installing PS4 R01 (on Win 2003). It's been revised as of April 13 and the readme indicates that it now includes some fixes that are from R01. I'm trying to figure out the proper way to go about installing post R01 fixes. Do I not install any unless I see a problem? Would I potentially be missing out on security fixes by doing this, or performance improving fixes that I may not directly notice until a user complained (which might not necessarily happen). Do I only install fixes with a release date After April 13 (there's only a few of them like that), or are all of them relevant?
