Shibboleth Service Provider Security Advisory [10 January 2013]

[Cantor, Scott]

Just a brief note about patching, this is the first "service patch" for
Windows that we have produced using the new installer. It installs like
other Windows updates and will appear in your "Updates" panel on Windows
2008 like Microsoft patches do, but won't "replace" the 2.5.1 installation
overall.

It does NOT install on top of 2.5.0, it requires the baseline version it
was built against, which is 2.5.1. Since 2.5.1 cleanly upgrades 2.5.0,
that's all as intended.
