WordPress 4.4.1 is available and we suggest you update ASAP to the latest WordPress version. While you are there also update your plugins and all themes, even themes you don’t use. This prevents any possible security issues running older versions of WordPress, Plugins and Themes.
You can set up auto update too by using JetPack and linking to your WordPress account.
We have a policy to click all updates each time we access our clients sites to keep thinks healthy.
