All creative cloud updates should be announced with information describing the update: what has changed, bug fixes, added features, etc.
While the desktop Creative Cloud app has gotten A LOT BIGGER, is constantly revised, and has options to show very little information in a variety of different ways, it does not indicate information on software updates.
For any given update notification, there is a drop down menu item for "more information". However, this simply takes one to info for the application, not the update. This menu item also duplicates the same functionality of a single click on the app (it takes you to the same page). Why is this "more information" menu item listed if it duplicates single click functionality?
Given Adobe's history for problem upgrades (introducing instability, removing features, versioning causing compatibility issues) any professional must assess whether any given upgrade is worth the risk, or should be set aside for a later, less risky time. This is impossible to do without information from Adobe on what has actually changed with any given upgrade.
The Creative Cloud desktop app is the place where this information should be "at hand" - easy to get to, well summarized.
