@cubecolor: Correct - I was unaware of that one.
@alchymyth: Didn't know about that one either. It's easy to miss though, because it appears that the "Right Now" info box is closed by default. It is for me anyway.
@Ipstenu: Well, if it was on the footer of every admin page, I would have found it. IMO the obvious first place to look for a version number is the top or bottom of pages. All I see at the top is "WordPress 3.4.2 is available! Please update now" and at the bottom "Get Version 3.4.2".
Curiosity aroused, I did a GREP search for the version number right across a WordPress installation, and discovered it can be found in each of the following files, though not always easily:
However, I stand by my original complaint. As far as I can still see, nowhere is the version number plainly obvious?
That's why its a question that has been asked countless number of times, as any search will demonstrate.
And so easily fixed!!!
