The only thing I can think of is that you didn't modify shib.conf at all, in which case the upgrade would change that file, specifically adding a Location block for /Shibboleth.sso with commands to guarantee that nothing blocks access to the handlers inadvertently. That's the area to check, and I would simply remove the modification and see if that matters. I have no idea why or how it would.
