Overnight Adobe has released a dot release update to both Acrobat 8 & Reader 8.
How about “offical” Vista support, integrated support for Acrobat in Office 2007 (Create PDF, Review etc etc in the toolbar of most Office applications), faster dynamic form rendering & improved 3D rendering amongst other things!
This free update is available immediately on Adobe.com;
