I’m delighted to say that the new Adobe CC desktop apps, plus a variety of new publishing & collaboration features, are now available. Log into the new creative.adobe.com to download the new versions.
There’s so much that’s new that I won’t even attempt to list features here (rather, I’ll keep posting individual pieces about things I find especially interesting), but you can get a quick overview on this Creative Cloud team blog post. They talk about what’s available now & what’s just around the corner (e.g. Typekit fonts on the desktop, automated Web graphics export from Photoshop, and more). For Photoshop-specific questions, check out this FAQ.
