These release notes for Ubuntu 10.10 (Maverick Meerkat) provide an overview of the release, and document the known issues with Ubuntu 10.10 and its variants.

Release Overview

Ubuntu Software Center

Ubuntu Software Center now shows "Featured" and "What's New" sections, a History of package installations and removals, and makes it easier to find add-ons for applications. It also offers Fluendo DVD Player for purchase, with more software to come soon.

Ubuntu Font

The Ubuntu Font Family is a brand-new typeface that is used for the user interface menus, widgets and titles in Ubuntu and Kubuntu. It covers Latin, Cyrillic and Greek in Ubuntu 10.10 with choices of Regular, Bold, Italic and Bold Italic styles and weights. The fonts also feature support for the new Indian Rupee Sign making Ubuntu 10.10 the first operating system to ship with out-of-the-box support for the world's newest currency symbol: ready for use by one billion Indians.

Designed with screen readability and aesthetic beauty in mind, the font was first seen in the new Ubuntu 10.04 logo design. It will continue to be expanded with Arabic, Hebrew, and Monospace support in future Ubuntu releases under the guidance of the Dalton Maag type foundry and the Canonical design team.

Installer

The Ubiquity Installer has been redesigned to be easier to use as well as to install drivers and download updates during installation.

Ubuntu Desktop Edition

The GNOME base platform has been updated to the current 2.32 version, including the new dconf and gsettings API.

Evolution was updated to the 2.30 version, which operates much faster compared to the version in Ubuntu 10.04 LTS.

Shotwell has replaced F-Spot as the default photo manager.

Gwibber has been updated to support the recent change in Twitter's authentication system, as well as changing the back end storage to improve performance.

The sound menu has been enhanced to include music player controls.

Ubuntu One has improved desktop integration with new sign-up and sign-in processes, Nautilus enhancements for managing folder sync preferences, faster file sync speed, and the ability to share links to music within the Ubuntu One Music Store.

Ubuntu Netbook Edition

The new Unity interface is now the default in Ubuntu Netbook Edition. It includes places for launching applications and browsing files, semantic search through the usage of zeitgeist, optimizing vertical space with a global menu bar and maximizing application by default.

A launcher is also available for keeping and dealing with mostly used applications. All favorites from UNE lucid or gnome panel items and desktop shortcuts are automatically shown in the launcher when you first run Unity.

The time is shown in the panel using a new module, indicator-datetime, which does not yet have a graphical setting for showing the date. A graphical setting would be provided in Ubuntu 11.04.

The standard photo management application has been switched to Shotwell and UNE comes will all goodness of the Desktop Edition too. Evolution is now performing a special mode more suited for netbook screen size.

A list of required hardware is available here.

Ubuntu Server Edition

We have added a major new version of Eucalyptus (version 2.0) that provides numerous bug fixes, more stability, and better user management.

Ubuntu cloud images can now easily be run outside of an EC2 or UEC instance environment. This will allow you to quickly and easily test function in cloud-init or other features of the image without needing to start a new instance. There is more information available on the Ubuntu wiki.

Canonical has also launched the Ubuntu Server on Cloud 10 program. Anyone will be able to try out Ubuntu 10.10 Server Edition on Amazon EC2 for free for one hour. Visitors to the download pages will now be able to choose to experience the ease and speed of public cloud computing and Ubuntu.

Kubuntu

Kubuntu 10.10 comes with the latest KDE Software. KDE Platform, Workspaces and Applications were updated to 4.5.1.

For 10.10, Kubuntu has merged the Desktop and Netbook images into one image featuring both the Plasma Desktop and Plasma Netbook workspaces. The appropriate workspace for your machine will be launched at login, you can also change the workspace in System Settings.

Plasma Netbook now sports the Global Menu by default.

The new KDE bluetooth application collection Bluedevil is now installed by default.

Pulseaudio is the default sound server to match other Ubuntu variants.

KPackageKit updates bring a faster backend and an updated UI with an application based view. It also has new features such as a backup/restore tool for the list of installed packages.

Xubuntu

Xfce4 was updated to the current 4.6.2 release. This fixes many of the bugs and updates the programs used in Xubuntu.

New default applications: Parole (Xfce4 Media Player) replaced Totem Movie Player, Xfburn (Xfce4 CD/DVD burning tool) replaced Brassero, and xfce4-taskmanager (Xfce4 process manager) replaced Gnome-Task-Manager. See the Xubuntu release notes.

Edubuntu

Edubuntu features an easier than ever installation for LTSP and netbook users. It also now ships with Gnome Nanny, a tool for restricting computer access to users at certain times that also provides basic content filtering.

Ubuntu Netbook Remix is now replaced with the Unity interface. LTSP has been updated to 5.2.4 and the Edubuntu menueditor has been updated to fix issues in the previous release.

Edubuntu also includes now additional wallpapers and language support has now been expanded to 143 languages.

During this release cycle Edubuntu also got a brand new website and now has presence on the most popular social networking sites.

Ubuntu Studio

Ubuntu Studio has had several applications updated and includes the changes from Ubuntu. There is now better integration between Pulse Audio and JACK - starting JACK does not automatically suspend Pulse Audio anymore. JACK and Pulse Audio can be used side by side if they are using different audio interfaces, if they are trying to use the same audio interface JACK will take precedent. In addition, the network connections can now be configured with gnome-network-admin.

Mythbuntu

In this release, Mythbuntu has updated to MythTV 0.23.1. There is also a new backup and restore tool.

Linux kernel 2.6.35

RC includes the 2.6.35-22.33 kernel which is based on the 2.6.35.4 Upstream stable kernel.

This kernel includes additional input subsystem patches for improved multitouch capability, improved support for Intel Sandybridge which includes support for 82579 LOM's, Apparmor bug fixes, reverts some KMS disablement patches, and general security updates (CVE-2010-3081,CVE-2010-3301). With 10.10 we have also dropped support for i586 and lower processors, as well as i686 processors without cmov support.

This kernel also includes new security enhancements. Of major note is the change to the default behavior of PTRACE which is used by gdb, strace, ltrace, etc. The behavior for 10.10 is that only child processes can be PTRACEd, due to the default value of "1" in /proc/sys/kernel/ptrace_scope. This value may be inappropriate for some development systems and servers with only admin accounts. If using "sudo" for PTRACE is not desired, please change this value to "0", though read /etc/sysctl.d/10-ptrace.conf for more details.

There will be a kernel update made available shortly after the release.


Installation

Overview

The graphical installer has been streamlined and given a substantial visual redesign. It now only asks the minimum of questions (language and partitioning) before it starts to copy files from the CD, and asks the remaining questions while transferring files to disk.

The new btrfs file system may now be used during installation via manual partitioning, as long as /boot is on some other file system.

System Requirements

The minimum memory requirement for Ubuntu 10.10 is 256 MB of memory. Note that some of your system's memory may be unavailable due to being used by the graphics card. If your computer has only the minimum amount of memory, the installation process will take longer than normal; however, it will complete successfully, and the system will perform adequately once installed.

Systems with less memory may be able to select "Install Ubuntu" from the boot menu to run just the installer, rather than the whole desktop, or may be able to use the alternate install CD.

Known Issues

Boot, installation, upgrade and post-install

end_request: I/O error, dev sr0, sector 437628

these error messages indicate that the system is still trying to access some files on the CD, and are harmless except that they obscure the message asking the user to press Enter to reboot. You can safely remove the CD from the tray and press Enter at this point to reboot to your new Ubuntu system. (539027)
