There is a bug in the detection logic on that page for the latest version of Flash Player for Linux (this has been reported to the folks who manage that page). The about Flash Player page is updated with the latest Flash Player versions available on desktop systems. The latest version for Linux is 18.104.22.1686 (released on 04-Feb). 22.214.171.124 is the last supported Flash Player version for Solaris.
Thanks. I will then consider this closed as I am now at the latest version of flash for those two operating systems. It's a shame Adobe decided to drop those operating systems from thier products.
