Ubuntu founder Mark Shuttleworth has announce the alliterative codename for Ubuntu 10.04 which will be released in April: Lucid Lynx. Ubuntu 10.04 LTS will ship in April 2010 and is the finale of significant work in Ubuntu, in Debian and across the free software ecosystem. LTS releases are maintained for five years on the server and three years on the desktop. This means that security updates will be available for five years for servers and three years for desktops. Regular Ubuntu releases are only supported for eighteen months.
Shuttleworth introduced the LTS concept in 2006 with the release of Dapper Drake. The enhanced stability and longer lifecycle of LTS releases make them appealing to hardware makers organizations that are rolling out large Ubuntu deployments. The last LTS version was 8.04, codenamed Hardy Heron, which was released in 2008.
Lucid will continue our tradition of focusing an LTS on a quality, stable and consistent experience and will require a number of adjustments to the usual plan. In summary, we will be more conservative in the new code we bring into Ubuntu during the development cycle, and we will run a longer test period.
Our focus will be stabilisation and bug-fixing across the platform with additional refinements in quality in key areas such as user interface improvements, boot experience, browsing and installing the incredible catalogue of software available for Ubuntu, and continuing our tradition of best-of-breed hardware support. We will maintain the health and security of our lynx with point releases.
Speed is an essential ingredient in the attack of a lynx, and speed remains our goal. We have improved the boot time in each of the releases during this era of Ubuntu, and expect to complete some of the major improvements required for 10 second booting with Lucid.
