Introduction

Ubuntu 15.10 was released for public use on October 22nd, 2015.  Nicknamed “Wily Werewolf” it comes with a few upgrades and changes that are worth noting.  In this overview, we will briefly touch on the changes and upgrades in the newest version.  Ubuntu 15.10 is primarily noted as a stepping stone to the release of Ubuntu 16.04 LTS, the next Long-Term Service release coming in April 2016.  Most of the major features remain largely unchanged from the current 15.04 LTS.

New Features

Linux Kernel 4.2

  • AMDGPU kernel drivers
  • Intel Broxton support
  • F2FS file-system encryption support
  • NV-DIMM support

A kernel for Raspberry Pi 2 has also been added to the archives.

One of the major changes is the migration to utilize systemd as the primary init system going forward.
