Adobe has released a new preview version of Flash which it says provides big performance boosts.

Flash's reputation has taken a battering since Steve Jobs started asserting that the reason he wouldn't allow it on iOS devices is because it was a performance pig.
Meanwhile, Adobe has clearly been working feverishly to correct that problem.
Adobe today announced a new version codenamed "Square" which is available in full 64-bit versions for all operating systems (Windows, Mac, Linux) as well as using the new GPU support in Internet Explorer 9 for Windows.
The Flash team claims that the Windows version running in IE9 goes 35% faster in some circumstances — particularly animations that use a lot of bitmap graphics as well as ones that use transparency a lot.
Adobe says Square is "stable and ready for broad testing" but to "keep in mind this a sneak peak and not everything will be fully baked".
