Ubuntu 16.04.4 LTS (Xenial Xerus) Officially Released, Here’s What’s New

After it’s been delayed a couple of weeks due to the severe Meltdown and Spectre security vulnerabilities that affect billions of devices, Ubuntu 16.04.4 LTS maintenance update is finally here for existing users running Ubuntu 16.04.3 LTS and earlier versions. As expected, Ubuntu 16.04.4 LTS incorporates refreshed kernel and graphics stacks based on those of the Ubuntu 17.10 (Artful Aardvark) operating system. These include the Linux 4.13 kernel and Mesa 17.2.2 graphics stack for Intel and AMD GPUs.
