Ubuntu 16.04.4 LTS (Xenial Xerus) released

Canonical yesterday released the Ubuntu 16.04 LTS (Xenial Xerus) operating system version with new kernels and graphics cards built in.
 

 
After being delayed for a few weeks due to the Meltdown and Spectre affecting billions of devices, the Ubuntu 16.04.4 LTS maintenance update is finally here for existing users running Ubuntu 16.04.3 LTS as well as older versions.
As expected, the 16.04.4 LTS release integrates new kernels and graphics cards based on the Ubuntu 17.10 (Artful Aardvark) operating system. It includes the Linux 4.13 kernel and the Mesa 17.2.2 graphics list for Intel and AMD GPUs.
This means that any new installation of 16.04.4 LTS will be powered by the Linux 4.13 kernel and will use the latest Mesa 17.2.2 or newer graphics drivers by default. Of course, 16.04.4 LTS also includes updated components that you can install via the software repositories.
As with the previous LTS series, 16.04.4 includes a new hardware enablement list based on newer hardware. This support is offered across all architectures. Existing 16.04 LTS users only need to update their operating system.
When upgrading, you can choose to stay with the default 16.04 LTS kernel or install the latest one from 17.10.
Either way, both kernels are now secured against the Meltdown and Spectre security vulnerabilities, but if you need support for specific hardware, you can install the Artful HWE (Hardware Enablement) kernel included with Ubuntu 16.04.4 LTS.
To update your computers, simply open the Software Update utility and install all available updates. For new applications, you will need to download the 64-bit or 32-bit Ubuntu 16.04.4 LTS ISO images via the Ubuntu portal.
Of course, users of other official Ubuntu releases can now download the corresponding Кubuntu 16.04.4 LTS, Хubuntu 16.04.4 LTS, Lubuntu 16.04.4 LTS, Ubuntu MATE 16.04.4 LTS, Ubuntu GNOME 16.04.4 LTS, Mythbuntu 16.04.4 LTS, Ubuntu Kylin 16.04.4 LTS and Ubuntu Studio 16.04.4 LTS.
