IdP v4 SLO issues when wilcard certificates for websites

[Cantor, Scott]

For now, I've added a Logout Changes section to the 4.0 release notes and will update that section once I can do some research into the various points of control, including the certificate issue, but that won't be today. If there's a quick answer to that, Brent would have it, but otherwise I'll have to get into it next week.
