Release information for Ubuntu 9.04 Beta

Subject: Ubuntu 9.04 Beta released

The Ubuntu team is pleased to announce the beta release of Ubuntu 9.04 Desktop and Server editions. Codenamed "Jaunty Jackalope", 9.04 continues Ubuntu's proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution.

Ubuntu 9.04 Desktop Edition brings faster boot speeds and a new notification system to your everyday computing experience.

Ubuntu 9.04 Server Edition makes it easy to experiment with cloud computing using Eucalyptus on your own servers, and sports an improved mail server integration stack based on postfix and dovecot.

The Ubuntu 9.04 family of variants, Kubuntu, Xubuntu, Ubuntu Studio, and Mythbuntu, also reach beta status today.

Desktop features

Faster boot times: improvements to Ubuntu's start-up process mean you can spend less time waiting and more time being productive with your Ubuntu desktop.

Notification system: notifications, those alerts that signify a change of status on your system or whether someone is contacting you, have been been made consistent across applications to provide a pleasing, intuitive experience for users.

Please see for details.

Server features

Cloud computing: Eucalyptus puts you in control of your own cloud computing infrastructure, compatible with Amazon's Elastic Compute Cloud (EC2) but running on your own servers behind your firewall. Ubuntu Server Edition 9.04 will also see Ubuntu available on Amazon EC2 -- making it the most complete cloud environment available today.

Turn-key mail servers: the dovecot-postfix package in Ubuntu 9.04 provides an all-in-one solution for deploying SMTP, POP3, and IMAP services with integrated server-side filtering support.

Kubuntu features

Kubuntu, built on the amazing KDE 4.2, brings users a complete, full-featured KDE4 desktop with many new applications and innovations.

Please see for all the details.

Xubuntu features

Xubuntu comes with the light-weight Xfce 4.6 desktop environment for those who want a desktop that is easy to use, but places particular emphasis on conserving system resources.

It is recommended that users not use the new EXT4 filesystem with the linux-rt kernel on production systems due to some reports of instability.

Jack-audio-connection-kit now includes support for the Free Firewire Audio Drivers (FFADO,

Mythbuntu features

As of 9.04, Mythbuntu fits better into the Ubuntu ecosystem by using the same build methods as all other remixes and derivatives. Because of this, 9.04 has been a focus around stability and preparing for an easy transition to the next version of MythTV (0.22) later this year.
