Ubuntu 12.10 (Quantal Quetzal) will be released today (or tomorrow - depends on where you live) but there is another news that Ubuntu fans will be interested in. In the recent blog post, Mark Shuttleworth just announced that the codename of Ubuntu 13.04 will be Raring Ringtail.
Just like the former ones, this codename of Ubuntu 13.04 is a combination of an adjective and a name of an animal and both words begin with the letter R. Also according to the blog post, other candidate codenames of Ubuntu 13.04 are Runty Racoon, Rufflered Rhino and Randall Ross.
This is the first time I know that there is an animal species called Ringtail though. I checked Wikipedia but there are several results like Ringtail Lemur, Ringtail Cat and Ringtail Mongoose. I really dont know which ringtail is the chosen one :D.
Here are some pictures of the different ringtails:
