Guess there is an alphabetical naming convention for Ubuntu releases. The very first two releases were named Warty Warthog and Hoary Hedgehog (remember ?). Then came Dapper Drake (6.06), the first long-time support release. Then, the Edgy Eft (6.10), followed by Feisty Fawn (7.04) and the now, the Gutsy Gibbon (7.10). Also, the next release is announced to be Hardy Heron (8.04) expected in April 2008.

So, here it goes :

1. Ubuntu 6.06 (Dapper Drake)
2. Ubuntu 6.10 (Edgy Eft)
3. Ubuntu 7.04 (Feisty Fawn)
4. Ubuntu 7.10 (Gutsy Gibbon)
5. Ubuntu 8.04 (Hardy Heron) [expected : April 2008 ]
