WordPress 4 Upgrade

I got 3 of my 4 blogs upgraded to WordPress 4 tonight [Adult Beverages still needs to be done] which involves a few steps of preparation: backup files from the site, backup files from my local instance, backup the MySQL database and then click the upgrade button and hope it all goes off without a hitch.

So far, so good. Nice to be current, just to make sure in case one of the security fixes protects me from the nasty hackers and spam trolls.
