All copies of WordPress 4.9.3 updated to 4.9.4
One of the nice things about WordPress is that it automatically updates itself for important security and bug fixes. For example, if you installed WordPress 4.9.1, it would have automatically updated itself to version 4.9.2 on January 16, and to version 4.9.3 on February 5.
Unfortunately, WordPress 4.9.3 has a bug that prevents it from automatically updating itself to later versions. It needs to be manually updated to version 4.9.4 or later.
The WordPress 4.9.3 to 4.9.4 update is trivial (it fixes only this bug, after which automatic updates will work again), so we’ve updated every customer copy of WordPress 4.9.3 on our servers to version 4.9.4, just as if it had happened automatically.
Customers should not notice any change as a result of this — but as always, don’t hesitate to contact us if you have any trouble.
