In reply to Keith Davis.

This particular "sir" will be using a 3 day old server snapshot to completely wipe out the 4.2 release, 4.3 alpha and everything else on the server along with them.

Why? Because I wanted to work with the 4.2 release version, at least for a while, but a really weird thing happened here when WordPress updated from 4.2 RC4 to the 4.2 release.

Within a few seconds of updating, the WordPress Beta Tester plugin updated my brand new 4.2 release version, to 4.3 alpha.

When I saw the 4.2 welcome page, and right above it the words "4.3 alpha", I did a double take. I thought somebody had dropped a clanger. And then I figured out what had happened.

Now, I don't think that this was what anyone intended; least of all me. But as a result, I will be spending the next half hour or so, rewriting this little bit of local WordPress history.

Hopefully some kind code diver somewhere will read this and do some core diving, introduce a short delay, some logic or an on-screen warning, so that it doesn't happen again in the future.

Terence.
