I would like to be informed whenever there is a new version of a product available (Web GUI, Windows GUI, Universal GUI, SF, etc).
This can be by RSS feed, email or any other platform that supports notifications that i can subscribe to.
With this i am alerted when new versions are available and can start planning the rollout.
It would also be very useful when the change log for that new version is direct available. I use the change log to determinate how quick i want this version available to my (end) users.
