I just got an e-mail from WP that says "Howdy! Your site at http://GHotos.com has been updated automatically to WordPress 3.7.1."

I had upgraded the site to 3.7, did not modify the config file and the config file does not have the line of code in it.

The only odd thing is the update message is from right around the time that I logged in to check and see if it had updated. It had not and asked me to (up at the top of the screen) and I ignored it. I'm not sure if logging in possibly triggered it to update. (It's an interesting coincidence if it didn't).
