There is now a preview of Adobe® Flash® Player, which we’re calling “Square”, available on Adobe Labs. This preview includes support for two new areas — enhanced support for Microsoft’s Internet Explorer 9 Beta and native 64-bit support for all major desktop operating systems including Linux, Mac, and Windows.

As part of our collaboration with Microsoft’s Internet Explorer team, Flash Player “Square” has been enhanced to directly support the hardware-accelerated graphics capabilities in the newest version. In our internal testing, we’ve seen significant improvements in Flash Player graphics performance – exceeding 35% in Internet Explorer 9 Beta compared to Flash Player running in previous versions of IE.

Today we’re also sharing a refresh of the Linux 64-bit version of Flash Player together with the first preview of both the 64-bit Windows and Mac versions. Those who used the previous 64-bit version of Flash Player for Linux should find this new version even faster and more reliable.

These new preview versions are fully functional, so all content should be compatible, but keep in mind this a sneak peak. If you encounter any issues, we encourage you to file a bug in our public database.
