Ubuntu 9.10 (Next Version) is named Karmic Koala
Ubuntu founder Mark Shuttleworth revealed plans Friday for Ubuntu 9.10, which will be codenamed Karmic Koala. The developers plan to bring cloud capabilities to Ubuntu's server edition, boost startup performance on the desktop, and continue work on the distro's netbook flavor.
Ubuntu adheres to a time-based six-month release cycle. The next major release—version 9.04, codenamed Jaunty Jackalope—is moving towards feature freeze and is scheduled for launch in April. Ubuntu 9.10, which will be the next release after Jaunty, is planned for October.
Planning for the Karmic release will take place at the next Ubuntu Developer Summit (UDS) which will take place in Barcelona in May. For additional details about the event, check out Ubuntu community manager Jono Bacon's blog entry
