Mobile


Flash Player 11.1 is the last release of the Flash Player plug-in for mobile browsers. Adobe will not add support for new mobile device configurations (chipset, browser, OS version, etc.). Adobe will continue to provide critical bug fixes and security updates for existing device configurations through September 2013, and will also allow our source-code licensees to continue working on and releasing their own implementations.
