Adobe has released public betas of the next generation of both Adobe Flash Player, and Adobe AIR, highlighting how the essential browser plug-in and cross-platform runtime component share similar code and technologies. The most notable new feature is found exclusively in Flash Player 11 Beta: support for 64-bit browsers.
Flash Player 11 Beta 64-bit64-bit support has been in development since Flash 10.2, but until now has been available only as a limited pre-release build, codenamed Adobe Flash Player "Square". By incorporating it into the Beta release of Flash Player 11, Adobe has signalled its readiness for final release, due later this year.
One potentially confusing consequence of 64-bit browser support is the fact there are now four different versions of Flash Player 11 available in the form of separate 32-bit and 64-bit builds for both Internet Explorer (32-bit, 64-bit), and other browsers (32-bit, 64-bit), which include Firefox, Safari and Opera and Chrome.
