Hello,

# The seventh release (Gutsy Gibbon) was released in October 2007, release number 7.10.

# The eighth release (Hardy Heron) was released in April 2008, release number 8.04 LTS.

The above is a copypasta from the following link: http://www.ubuntu.com/aboutus/faq

So Karmic Koala will be Ubuntu 9.10 and not 10.09.

Be sure to give it a try. I've been running Kubuntu 9.04 since the beta release and am loving every minute of it.

Br,

Johannes
