It looks like there is no Flash player ver. 8 for Linux. The only information, available on the Internet on this issue is a blog entry by some developer from Macromedia, who claimed in December last year that version 8.0 would be skipped and 8.5 released for all platforms. Nothing happened since then.
The problem with Flash 7 is that Google Analytics are not displayed properly with it - all the captions are missing.
