Today's release of Ubuntu 15.04 is yet another installment in the slow and steady march forward from Canonical. The company knows that not every OS release needs to be accompanied by fanfare and dramatic changes to your desktop. And this edition of the popular Linux distro perfectly epitomizes that philosophy. There are basically zero user-facing interface changes, except for the ability to set application menus to always show, instead of only popping up when you mouse over them. Otherwise most of the changes are under the hood. The OS should be faster and more stable, thanks to updates to updates to the underlying system, like the Unity desktop and Linux kernel. The default apps also got some minor version bumps, including Firefox and LibreOffice.
