There's a new version of WordPress out. It is a security release, so we suggest that you upgrade to keep your website working without any compromises or shutdowns from your host.
WordPress 4.4.1 Security and Maintenance Release (wordpress.org)
WordPress 4.4.1 is now available. This is a security release for all previous versions and we strongly encourage you to update your sites immediately.
WordPress versions 4.4 and earlier are affected by a cross-site scripting vulnerability that could allow a site to be compromised.
And this:
Version 4.4.1 (codex.wordpress.org)
On 6 January 2016, WordPress 4.4.1 will be released to the public.
WordPress 4.4.1 contains fixes for 52 bugs from 4.4.
We suggest upgrading since this is a security release and since there are so many bugs that are fixed but it's up to you. There have been a number of plugins that have been upgraded recently, so it would be good to get this update done because we will also upgrade any plugins that are out of date.
Our Website Maintenance Department will be in contact with you regarding these upgrades. Clients that have signed up for our Automatic WordPress Update Program will get their website updated promptly.
