WordPress 4.7 just released! But, wait, don’t go pressing that “Update” button just yet.
First – Make sure you’ve got access to a full backup of your entire system. Database, plugins, uploads, core software, themes, child themes, CSS customizations, etc…
Second – Make sure you know how to actually restore from your backup. Otherwise, its like you have a backup generator in the garage, with no idea of how to use it when the power goes out.
Third – Wait a few days. Seriously. As always, this update has been tested extensively with hundreds of volunteers running it on their sites and reporting back with any errors.
