    <p>Hi All. 
      This is partly FYI, and partly something you may want to do.</p>
    <p>FYI - <u>Next week </u>the bugzilla folks will fold sev=major
      bugs into the critical category, and sev=trivial bugs into minor,
      and then the major and trivial categories will be forever removed
      from BMO. (You may have noticed severity major and trivial are not
      available when creating a new bug.) [1]<br>
    </p>
    <p>What you may want to do -  Some currently "major" bugs don't meet
      the new definition critical [2].  So in the next few days you may
      want to proactively review and change bugs you care about or
      manage, to avoid having them incorrectly shoved into critical (it
      may be  impossible to find and triage the old major bugs as a
      group after BMO moves them).  To aid you in this effort, see the
      sev=major column of this <a moz-do-not-send="true"
