I'd like to suggest having a page that shows a list of all modules and their version numbers, dates etc. for both Stable and Pre-Release updates.
The idea is simple - if someone thinks their product might not be updating, they can check the list, and see if their modules match. I've seen some people question that some modules haven't updated in a while, and have worried they have a problem. This would reduce posts about this, and mean people can possibly identify update issues.
