Adobe has released a test edition of their Flash Player codenamed Square.

This preview release comes with 64bit support on all the three popular desktop platforms.

The company said that this release features improved support for the just released Internet Explorer 9 Beta which is available in a 64bit edition.

Adobe said:

We have made this preview available so that users can test existing content and new platforms for compatibility and stability. Because this is a preview version of Flash Player, we don’t expect it to be as stable as a final release version of Flash Player. Use caution when installing Flash Player “Square” on production machines.


64-bit support — Native support for 64-bit operating systems and 64-bit web browsers on Linux, Mac OS, and Windows.

Internet Explorer 9 hardware accelerated rendering support — Enhanced support for Internet Explorer 9 Beta. It takes advantage of hardware accelerated graphics in Internet Explorer 9 Beta, utilizing hardware rendering surfaces to improve graphics performance and enable seamless composition.
