Raring Ringtail (Ubuntu Codename)
Raring Ringtail is the Ubuntu codename for version 13.04 of the Ubuntu Linux-based operating system. Officially released in April 2013, Raring Ringtail follows the Quantal Quetzal (v12.10) release and serves as a minor, non-LTS update for Ubuntu.
Ubuntu Raring Ringtail features an updated Linux kernel, 3.8, the latest OpenStack release (Grizzly) with high availability as a standard feature, and performance and quality improvements for desktop Ubuntu users. Graphical enhancements have been introduced as well to help prepare Ubuntu for convergence across a variety of computing devices, including PCs and laptops, tablets and smartphones.
Raring is an adjective that means ready or willing (as in “raring to go”), and the Ringtail is a North American mammal in the raccoon family. The ringtail is also sometimes referred to as a ring-tailed cat.
The Raring Ringtail release of Ubuntu Linux is expected to be succeeded by Saucy Salamander (Ubuntu v13.10) in October 2013.
