>Revisions are normally released to fix security vulnerabilities
    and are distinguished by an increase in the third number. For example,
    when 2.16.2 was released, it was a revision to 2.16.1.
    </P
><P
>Point releases are normally released when the Bugzilla team feels
    that there has been a significant amount of progress made between the
    last point release and the current time. These are often proceeded by a
    stabilization period and release candidates, however the use of 
    development versions or release candidates is beyond the scope of this
    document. Point releases can be distinguished by an increase in the
    second number, or minor version. For example, 2.16.2 is a newer point
    release than 2.14.5.
    </P
><P
>The examples in this section are written as if you were updating
    to version 2.16.2.  The procedures are the same regardless if you are
    updating to a new point release or a new revision.  However, the chance
    of running into trouble increases when upgrading to a new point release,
    escpecially if you've made local changes.
    </P
><P
>These examples also assume that your Bugzilla installation is at
    <TT
CLASS="filename"
>/var/www/html/bugzilla</TT

    simply substitute the proper paths where appropriate.

>The Bugzilla team will normally make a patch file available for
      revisions to go from the most recent revision to the new one. You could
      also read the release notes and grab the patches attached to the
      mentioned bug, but it is safer to use the released patch file as
      sometimes patches get changed before they get checked in. 
      It is also theoretically possible to
      scour the fixed bug list and pick and choose which patches to apply
      from a point release, but this is not recommended either as what you'll
      end up with is a hodge podge Bugzilla that isn't really any version.
      This would also make it more difficult to upgrade in the future.
