It’s been almost two years since the April 21, 2016 release of the Ubuntu 16.04 LTS (Xenial Xerus) operating system series, which already received four of five scheduled maintenance updates, the last one being Ubuntu 16.04.4 LTS, launched last month on March 1, 2018. While Ubuntu 16.04.4 LTS brought up-to-date kernel and graphics stacks from the Ubuntu 17.10 (Artful Aardvark) release, there’s been a lot of changes happing in Ubuntu since the initial release and we bet that Ubuntu 16.04 LTS users would want to know what they get if they’ll upgrade to Ubuntu 18.04 LTS later this month.
