Ubuntu 11.10 Oneiric Ocelot Released Running on Linux 3.0 Kernel

Today marks the official release of Ubuntu 11.10 named Oneiric Ocelot. Ubuntu has been making great progress with each new release. This release has a great deal of improvements and is the first Ubuntu release to use the Linux 3.0 Kernel

Oneiric Ocelot’s release notes give the full technical details but here are some highlights.

General Ubuntu Improvements

  • Unity is the default whether with 3D acceleration or with a fallback to 2D
  • A new Alt+Tab switcher
  • “Places” are renamed to “Lenses”. This feature now also integrates multiple sources and advanced filtering options like ratings, range, and categories.
  • The Dash has a new music lens, linked to Banshee, that searches your personal and online music collections.
  • Better performance of launchers and panel, ported to GTK 3 and GTK 3-based indicator stack.
  • Full support for Chinese, Japanese, Korean, and other script languages.
  • Ubuntu Software Center 5.0
  • OneConf is now built in to keep your installed applications in sync between multiple computers.

  • New ARM sub architectures
    armel+ac100 for the Toshiba ac100 netbook (NVIDIA Tegra 2 SoC)
    armel+mx5 targeted at the Freescale i.MX53 Quick Start development board

  • Revised DVD content

  • New App Developer Site
  • Thunderbird is now the default email client
  • Backups are easy in Ubuntu 11.10 now that Déjà Dup is included as the default backup tool. Securely store copies of your important data on a separate hard drive, cloud server, or even Ubuntu One.
  • GNOME 3.2
  • Ubuntu now uses the LightDM login manager with the Unity greeter.

Ubuntu Server Improvements

  • Juju is available in Ubuntu 11.10 as a technical preview. Juju is a service deployment and orchestration framework developed by Canonical and used to deploy and manage services both on bare-metal and in the cloud.
  • Orchestra is a collection of the best free software services for provisioning, deploying, hosting, managing, and orchestrating datacenter services.
  • Ubuntu Server 11.10 is the first release with support for the ARM architecture. In this last cycle, the Ubuntu Server team worked closely with the Ubuntu ARM team to deliver a technical preview of ARM server support in Ubuntu Server 11.10.
  • The Xen hypervisor has now been reintroduced as an option in Ubuntu Server.

Ubuntu Common Infrastructure

  • All ISO images released with Ubuntu 11.10 are hybrid CD/USB images that can be written directly to a USB disk and booted without the use of special software. Users who wish to enable persistent storage on a USB stick can still use the usb-creator tool to configure the USB stick.
  • Ubuntu 11.10 provides “multiarch” support for installing 32-bit library and application packages on 64-bit systems. For all amd64 installs and upgrades, select 32-bit software (like Skype and Flash), will now be installable directly using the same 32-bit packages that are used on i386 installations.
  • Linux 3.0 Kernel
  • GCC 4.6 Toolchain

All of these changes go to make this the best Ubuntu release yet. I was particularly excited to see Xen native dom0 support come back since it is included in Linux 3.0 Kernel. I am also especially interested in the ARM support. I am a big advocate of energy efficient computing and ARM is a great platform I have used before with OpenBSD.

Ubuntu 11.10 is available for download from Ubuntu’s site. It comes in both Ubuntu and Ubuntu Server varieties.
