Notification if Perch Runway needs to be updated?

I've been working to update two Perch Runway sites today. I saw the version number is 3.0.1 on a site I upgraded from Perch Runway 2 to Perch Runway 3.

On another site which I had already updated that it was running 3.0, but there wasn't a note that there was an update available.

Is there a note that I didn't see to let me know if Perch Runway needs to be updated?

I seem to recall in there was a note in Perch 2. (Amazing how quickly I've become used to Perch 3. Lovely update!)

Also, is the update button the recommended method to update locally? I'm not sure if I would use it to update a production site to be safe, yet it does save a few steps in the process which is very helpful.

Here's my summary info from the site where I didn't see the note that there was an update available. (BTW, thank you for listing if installed AddOns are up-to-date).
