Flash Player 20 was released earlier this week as noted in the Security bulletin linked to. Please see Adobe Flash Player Distribution | Adobe for information on Flash Player enterprise distribution and obtaining the distribution license, if you haven't done so already.
Flash Player beta program is on-going with weekly releases, as such, we're constantly posting beta versions.
Thanks for the answer, but it's still not clear to me, sorry!
I need to know how to solve the vulnerabilities noted in Adobe Security Bulletin with stable (NOT BETA) version of Adobe. I need a confirmation that 22.214.171.124 (IE) and 126.96.36.199 (Firefox) are not BETA versions.
The reason I ask is because Adobe Labs says version 20 is beta version (Download Adobe Flash Player 20 Beta for Desktops - Adobe Labs) and we are not allowed to install BETA versions in the enterprise, because BETA sounds like not stable versions.
The version listed in the Security bulletin is the latest, stable, version that addresses the vulnerability listed in the security bulletin. That is the version you want to install. The security bulletin will never list beta versions.
The version(s) on the beta channel is for the next version of Flash Player, updated weekly and not stable.
