From Adobe:
Explore a brand-new set of rich features when you get Adobe® Photoshop® software through Adobe Creative Cloud™. Instead of waiting for a new version of Photoshop, Creative Cloud members have immediate access* to exclusive new features† — plus storage and sharing capabilities.
Some of the new features include:
Smart Object support for Blur Gallery and Liquify — Smart Object support gives you the freedom of nondestructive editing when using Liquify and the new Blur Gallery effects introduced in Photoshop CS6.
Powerful CSS support — Now you can export CSS code for text and objects and import color swatches from HTML and CSS files to make your web designing faster and easier.
Timesaving features — Be more productive with helpful new features, including a better way to name merged layers, Crop tool refinements, and more.
Adobe is offering Creative Cloud Introductory Pricing for existing CS customers.
