I'm on your hosted cloud and my instance upgrades automatically. I'm ok with that but it would be helpful to know when the new build is release/installed and what changes occur.
Ideally, we'd like our updates to be seamless and not impact your business. For our own information, are you interested in a change log to see new features, or are you looking out for specific changes that might impact your business?
We do have an output stream that is updated regularly.
A change log would be fine, but more importantly a notification "push" announcement for when you upgrade the instances. I have other tools which email an announcement on version updates, especially when they are applied automatically like yours. I don't mind checking the site for the change log but I shouldn't find out about an upgrade to my instance after it's occurred. I should be notified in advance.
