Ubuntu 16.04 LTS (Xenial Xerus) Updates to Linux Kernel 4.3.3, Tracks Linux 4.4 RC5

We can report today that the Ubuntu kernel devs managed to update the Linux kernel packages of the upcoming Ubuntu 16.04 LTS (Xenial Xerus) operating system on the recently released Linux 4.3.3 kernel. On the other hand, they are still tracking the Linux 4.4 kernel, which will be an LTS (Long-Term Supported) branch. The Linux kernel 4.4 packages are available in the unstable repositories of Ubuntu 16.04 LTS, and they’ve just been updated to the Linux kernel 4.4 RC5 release announced by Linus Torvalds a few days ago.
