Posted on: 04/22/2010 09:06 PM

The release candidate of Ubuntu 10.04 LTS has been released:

]The Ubuntu team is pleased to announce the Release Candidate for Ubuntu 10.04 LTS (Long-Term Support) Desktop and Server Editions and Ubuntu 10.04 LTS Server for Ubuntu Enterprise Cloud (UEC) and Amazon's EC2, as well as Ubuntu 10.04 Netbook Edition. Codenamed "Lucid Lynx", 10.04 LTS 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.

buntu 10.04 LTS Desktop Edition and Ubuntu 10.04 Netbook Edition continue the trend of ever-faster boot speeds, with improved startup times and a streamlined, smoother boot experience.

Ubuntu 10.04 LTS Server Edition provides even better integration of the Ubuntu Enterprise Cloud, with its install-time cloud setup.

Ubuntu 10.04 LTS Server for UEC and EC2 brings the power and stability of the Ubuntu Server Edition to cloud computing, whether you're using Amazon EC2 or your own Ubuntu Enterprise Cloud.

The Ubuntu 10.04 family of variants, Kubuntu, Xubuntu, Edubuntu, Ubuntu Studio, and Mythbuntu, also reach beta status today.

The final release of Ubuntu 10.04 LTS is scheduled for 29 April 2010 and will be supported for three years on desktops and five years on servers.

Before installing or upgrading to Ubuntu 10.04 LTS, please review the instructions and caveats in the release notes:

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 8.04 LTS or Ubuntu 9.10 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
----------------

Social from the start: We now feature built-in integration with Twitter, identi.ca, Facebook, and other social networks with the MeMenu in the panel.

New Design: Cleaner and faster boot, new notification area, new themes, new icons, and new wallpaper bring a dramatically updated look and feel to Ubuntu.

Ubuntu One: Synchronize any folder in your home directory, publish files to share with the Internet directly from your Ubuntu desktop, manage more sync settings with the Ubuntu One Preferences application, use Rhythmbox to choose from millions of songs available for purchase in the Ubuntu One Music Store.

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

Cloud computing: The Ubuntu Enterprise Cloud installer has been vastly improved in order to support alternative installation topologies. UEC components are now automatically discovered and registered, even when the storage controller, cluster controller and walrus are installed on different servers. Finally, UEC is now powered by the latest Eucalyptus version 1.6.2.

UEC and EC2: Ubuntu 10.04 LTS continues the tradition of official Ubuntu Server image releases for UEC and for Amazon's EC2, giving you everything you need for rapid deployment of Ubuntu instances in a cloud computing environment. UEC images, and information on running Ubuntu 10.04 on EC2, are available at:

http://uec-images.ubuntu.com/releases/10.04/rc

Stability and security: Ubuntu 10.04 LTS brings many improvements over Ubuntu 8.04 LTS to keep your servers safe and secure for the next five years, including AppArmor profiles for many key services, kernel hardening, and an easy-to-configure firewall.

Ubuntu Netbook features
-----------------------

Ubuntu Netbook Edition is optimised to run on Intel atom based netbooks. It includes a new consumer-friendly interface that allows users to quickly and easily get on-line and use their favourite applications. This interface is optimised for a retail sales environment.

It includes the same faster boot times and improved boot experience as Ubuntu desktop.

Ubuntu Netbook on ARM
---------------------

The ARM optimised variant of Ubuntu Netbook comes with a lightweight application selection tailored specifically for ARM deployments, including a web-based office and mail solution and a launcher that works with and without graphics acceleration.

Kubuntu features
----------------

Kubuntu 10.04 LTS will be the first LTS to feature KDE 4 Platform and Applications. KDE 4 has come a long way since its early releases and is now suitable for the high demands of LTS users. Being an LTS we have focused on bug fixing and stability for this release, but we did find time to add features such as touchpad configuration, Firefox KDE integration, Kubuntu notification improvements, and cross-desktop systray menu standardisation. Kubuntu features the Plasma Desktop while Kubuntu Netbook Remix comes out of preview status with the Plasma Netbook workspace.

See https://wiki.kubuntu.org/LucidLynx/RC/Kubuntu for more details.

Edubuntu features
-----------------

Edubuntu 10.04 includes many new features, updates and fixes. Some highlights include:

LTSP and the Ubuntu Netbook Remix interface can now be installed from the Live DVD right after system installation. The disc also features Live LTSP, which allows you to try out LTSP without making any permanent changes to your machine.

New and updated software, including a new menu editor for menus that can be applied to user profiles. GBrainy is a new program in the Edubuntu suite that excercises your brain.

A new icon theme which uses more descriptive icons, a new wallpaper and boot splash screen as well as more subtle window theming that is easier on the eyes.

Mythbuntu features
------------------

Mythbuntu 10.04 introduces MythTV 0.23. This new version is significantly faster and should feel more responsive and stable than older versions. It also integrates better into the OS with better support for things like ConsoleKit and Upstart.

Please see http://www.mythtv.org/wiki/Release_Notes_-_0.23 for more details about changes introduced in 0.23.

See http://mythbuntu.org/10.04/rc for information about the Mythbuntu beta release.
