Final is now out.
Changes:

Quote:- Added support for CSS animations
- The Do-Not-Track header preference has been moved to increase discoverability
- Tuned HTTP idle connection logic for increased performance
- Improved canvas, JavaScript, memory, and networking performance
- Improved standards support for HTML5, XHR, MathML, SMIL, and canvas
- Improved spell checking for some locales
- Improved desktop environment integration for Linux users
- WebGL content can no longer load cross-domain textures
- Background tabs have setTimeout and setInterval clamped to 1000ms to improve performance
- Fixed several stability issues
- Fixed several security issues

I think this quicker cycle might have a bit of a detrimental effect on plugins...
Otherwise, really mostly *tweaks* from my point of view.  I probably won't bother upgrading any time soon.
