TeamSite 5.5.2 vs 5.5.1

Grundy

Hello all,
My company has tasked me with assessing differences between versions 5.5.1 and 5.5.2 of TeamSite. I have to assume that 5.5.2 is considered "better" since its predecessor isn't even available for download anymore, but I'm having trouble locating documents which detail specific differences between the two.

Release notes for 5.5.2 contain a list of enhancements and bug fixes, but I'm not sure whether these are relative to 5.5.1 or to the 5.0 platform. Does anybody know if there is a comprehensive version history or similar document from Interwoven to help pinpoint the pros/cons of this minor-version upgrade? If so, where can I find it?

Thanks,
Nutt
