Microsoft retires security bulletins that have been part of its patch disclosure policies since 1998. A searchable database of support documents will replace the bulletins. Patch Tuesday was canceled in February just hours before the security updates were to reach customers. Microsoft kept bulletins the following month as well, saying it wanted to give users more time to prepare for the change to SUG. One patch expert says SUG portal has “some great capabilities,” but is not impressed with the SUG substitute.”]
