I just now visited Adobe's site: https://get.adobe.com/flashplayer/ with my Windows 7 and Firefox, and they are offering only the vulnerable 19.0.0.207 version.
Pray tell, where did they release .209 to, if not their own website? What OS and browser are you running, to see .209?
The .209 download is on the Adobe Labs Downloads site.
Arrow down to the Flash Player 19 Beta and select the appropriate version(s).
