Ubuntu 9.04 Release Candidate
Posted on: 04/17/2009 10:31 AM

The release candidate of Ubuntu 9.04 is now available

The Ubuntu team is pleased to announce the Release Candidate for Ubuntu 9.04 Desktop and Server editions and Ubuntu Netbook Remix. 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.

We consider this release candidate to be complete, stable, and suitable for testing by any user.

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.

Ubuntu 9.04 Netbook Remix brings a new, easy-to-use interface that is designed to be used on the smaller screens of netbook devices.

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

The final release of Ubuntu 9.04 is scheduled for 23 April 2009 and will be supported for 18 months on both desktops and servers. Users requiring a longer support lifetime may choose to continue using Ubuntu 8.04 LTS, with security support until 2011 on the desktop and 2013 on the server, rather than upgrade to 9.04.

Before installing or upgrading to Ubuntu 9.04 please review the instructions and caveats in the release notes:

In addition, there are a small number of known bugs in the release candidate that will be fixed before the Ubuntu 9.04 release, but warrant highlighting for your attention:

About The Release Candidate
---------------------------

The purpose of the Release Candidate is to solicit one last round of testing before the final release. Here are ways that you can help:

* Upgrade from Ubuntu or Kubuntu 8.10 to the Release Candidate by following the instructions in the release notes referenced above.

* Participate in installation testing using the Release Candidate CD images, by following the testing and reporting instructions at
http://wiki.ubuntu.com/Testing/ISO


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 made consistent across applications to provide a pleasing, intuitive experience for users.

Server features
---------------

Cloud computing: Ubuntu Enterprise Cloud (powered by 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.

Netbook Remix features
----------------------

Built-for-purpose interface: favourite applications and websites are just a click away, making Ubuntu Netbook Remix a great choice for netbook users.

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 Netbook desktop.

Ubuntu Netbook Remix is known to work on these netbook models:
Asus Eee PC 900
Acer Aspire One
Dell Mini 9

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 https://wiki.kubuntu.org/JauntyJackalope/RC/Kubuntu for 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.

Please see https://wiki.ubuntu.com/Xubuntu/JauntyJackalope/RC for further
details.

Ubuntu Studio features
----------------------

Ubuntu Studio includes updates to input hardware and sound device management from Ubuntu Desktop and a complete suite of tools for generation of audio, video, and graphic content.

Ubuntu Studio 9.04 also features a streamlined installation process, giving you a familiar Ubuntu desktop and all of your studio applications in a single step.

The realtime kernel flavor (linux-rt) has returned and is again used by default in Ubuntu Studio. The rtirq script (http://alsa.opensrc.org/Rtirq) is also now included in the ubuntustudio-audio package. 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, www.ffado.org).

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.

Unfortunately, the main Mythbuntu website, http://mythbuntu.org is temporarily down due to a problem with the hosting provider. RC images will still be available at http://cdimage.ubuntu.com/mythbuntu/releases/jaunty . We'll restore the other mirrors as soon as the main site returns.
