The final Flash Player 9 on Linux is due early next year. According to an FAQ put out by Adobe, the Linux version will support the same features as Flash on Macintosh and Windows.
The beta of Flash Player 9 for Linux supports most of the features except a full-screen mode and support for SSL (secure sockets layer) encryption.
The company declined to indicate when the final version of future 64-bit versions will be available.
People can develop applications using Adobe's Flex 2 software developer's kit, and those Flash programs will run on Windows, Macintosh or Linux, according to Adobe.
