For the first time ever, Adobe is delivering a widely available Photoshop CS3 beta to enable customers to more easily transition to the latest hardware platforms, particularly Apple's new Intel based systems. The beta is available as a Universal Binary for the Macintosh platform as well for Microsoft Windows XP and Windows Vista computers, with the final shipping release of Adobe Photoshop CS3 planned for spring 2007.
Adobe has a long-standing commitment to the Mac community and this release is Adobe's way of delivering native performance on Intel based systems many months earlier than we otherwise could have done. We have no doubt, however, that all of our customers will enjoy exploring the new Photoshop CS3 beta and seeing some of the new features we have in store. The full application is not yet complete; but, many of the additions to the product are fully implemented and ready for you to try and discuss.

The Photoshop CS3 beta is available in English only but to Photoshop CS2 users worldwide. It is available to licensed users of either the Photoshop CS2 (full, upgrade, and education), Adobe Creative Suite 2 Standard or Premium (full, upgrade, and education), Adobe Production Studio Standard and Premium (full, upgrade, and education), Adobe Video Bundle (full, upgrade, and education) or Adobe Web Bundle (full, upgrade, and education). You will need to provide your Photoshop CS2, Creative Suite, Production Studio or Bundle serial number in order to get a Photoshop CS3 beta serial number, enabling you to activate the Photoshop beta and use it beyond the two-day grace period.
