[Zope] Zope 2.10.4 Upgrade

I recently upgraded from Zope 2.10.0 to 2.10.4. However, the Zope instance still reflects 2.10.0 in the control panel. I installed Zope 2.10.4. Then, in my instance, I changed the variables in 'zopectl' and 'zope.conf' to reflect the new 2.10.4 version and restarted. Did I miss a step? Thanks in Advance, Dave
