As for the recent confusion about the Adobe Flash Player updates.
Release Notes: http://forums.adobe.com/thread/1300160?tstart=0
My two cents.
That's the reason why I believe users should always post both the release notes/changelog (and looking for them before posting) and the official download links.
Actually the IE plugin was updated twice. I got a notice about an update last week sometime and it said on the page that it was the .175 version. I had the .168 and when I downloaded and installed the update, I had .174. Now I updated again and I have .175.
