As announced at Adobe MAX 2015, Adobe released new updates to its professional Creative Cloud suite of applications. Photoshop CC, Illustrator CC, InDesign CC, Premiere Pro CC, After Effects CC, Audition CC, Dreamweaver CC, Photoshop CC, Fuse CC (Preview), Adobe Stock, and more have been updated. You can download the new versions from the Adobe Creative Cloud app.
Photoshop CC features updates that integrate it more tightly with Adobe Stock and other asset services in addition to designer-pleasing features such as art board support in Photoshop. Photoshop's continued dark and now-"enhanced" UI will take some getting used to (many will likely tweak more settings), but some features are clearly better refinements that aid in daily activities. Audition CC features some pretty awesome automated music-to-timeline-matching features (Remix), and other video-related apps welcome a bevy of new refinements to color control, etc. Either way, common sense dictates that you should wait until a subsequent bug-fix update if you want a smoother transition.
Of note, Flash CC is now renamed and updated to Animate CC in acknowledgement of the fact that HTML5 is the predominant and preferred technology for producing animations over what's often been lauded as the buggy, insecure, and power-hungry Flash animation.
Because each of these applications' new features is quite specific and only of interest if you use the application in question frequently, we'll let you explore all that's new through Adobe's videos and blog posts on the updates.
Last note: I was unable to update through my Photoshop CC app at first from 2015.0.1 (the most recent version before today) to 2015.1. For those having issues despite signing out and logging back in and/or quitting and restarting the Creative Cloud app, this is what worked for me: Download and install the original version of Photoshop CC (2015) (or any app) by downloading here (sign in, and Creative Cloud will take over your update once you get to the "Photoshop is downloading now" page). Continue after the warning of reverting to an earlier version. Once installed, CC saw an update and installed to the latest release from today. Presto. If your Photoshop CC now opens with a new dialog showing your most recently opened apps, you're there. So far, this is the only way I've been able to "automatically" update my CC apps without opening a chat with Adobe Support and letting them take over my computer to delete and add various program files.
Update: Adobe has a great blog post solely with information on the Photoshop CC update and the Fuse CC Preview. Adobe Stock integration is better than ever; and with competitive pricing at $9.99 per image, $79.99 per video, and $29.99/mo. and $199.99/mo. plans for ten and 750 images per month, respectively, Adobe is positioning itself extremely well to take a serious chunk of the stock photography market.
