11.4 The Software may automatically download and install updates from Adobe. These updates are designed to improve, enhance and further develop the Services and may take the form of bug fixes, enhanced functions, new Software modules, and completely new versions. You agree to receive such updates (and permit Adobe to deliver these to you with or without your knowledge) as part of your use of the Services.
Let's talk reality, not agreements. Those are usually worded to cover their ass.
Adobe has said that they will not automatically install new versions, and instead will try to keep up to 5 prior versions for your use. Now there are bug fixes and smaller updates, sure, but so far you have to specifically run the Adobe Application Manager or the Updates functionality to even install that.
