Adobe previews 64-bit Flash Player
Having temporarily withdrawn any form of Flash Player 10 support for 64-bit Linux some months ago in June, in favour of an integrated cross-platform development effort, Adobe is now providing a preview version of its Flash Player for 64-bit Windows, Mac OS X and Linux systems. Code named "Square", the proprietary preview is now available for download from its dedicated web page. While Linux users have been able to fall back on various open source Flash players, such as Gnash or SWFdec, these unfortunately lag behind Flash development and don't reliably play all Flash files.
On his Adobe blog, John Nack writes that internal tests running with Internet Explorer show performance increases of up to 35% over previous versions. The company has now published a support FAQ document answering important questions about Flash and discussing the challenges of coding Flash for 64-bit systems.
The company advises that previous Flash players must be uninstalled before installing the new preview version. To remove the preview version itself Windows and Mac OS X users need only download and run an Unistall.exe file. Linux users must delete the libflashplayer.so binary file from their browser plug-in folder. Previously the NSPluginWrapper was required on 64-bit Linux systems, but with "Square" this is no longer necessary.
Adobe warns that the 64-bit preview is not suitable for production use and points out that there is no automatic update support on this preview. Adobe give no indication of when a final version might be available.
