As of Multigraph version 3.0, released on August 5, 2010, Multigraph now requires Flash Player version 10. Additionally, developers using the Multigraph Flex component will need to use version 4 of the Flex SDK to compile their applications. If you need to continue supporting an older version of Flash Player, or compiling with an older version of the Flex SDK, you can use older (2.5 or lower) version of Multigraph available from the download archives.
