The Flash 9 beta for Linux has finally been released! There are two packages available, a Mozilla/Firefox plugin and a GTK based standalone player. The player does not include full-screen mode and the standalone player doesn’t have SSL support just yet, both of which will be available in the final release.

The release has been tested on Red Hat Enterprise 3 &4, SUSE 9.x and 10.1 by Adobe. I can confirm that everything works fine under Ubuntu too. You should be able to install it by simply removing all previous Flash versions and copying libflashplayer.so to either ~/.mozilla/plugins/ or /usr/lib/firefox/plugins/.
