New features in Maverick

Feature development for Maverick has completed. Please see the Maverick blueprint list for details.

Please test and report any bugs you find:

Updated Packages

As with every new release, packages--applications and software of all kinds--are being updated at a rapid pace. Many of these packages came from an automatic sync from Debian's Unstable branch. The period of automatic syncs has stopped now, so from now on there will be fewer changes.

For a list of all packages being accepted for 10.10 Maverick Meerkat, please subscribe to maverick-changes:

Ubuntu Font Family

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.

Ubuntu Desktop Edition

The GNOME base platform has been updated to the current 2.32 versions. This particularly includes 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 Indicator has been enhanced to include music player controls.

The Ubuntu Software Center has an updated look and feel, including the new "Featured" and "What's New" views for showcasing applications, an improved package description view, and a "For Purchase" software category has been added. You can also now easily access your package installation history too.

Ubuntu One: Polished desktop integration with new sign up and sign in process. Tighter integration with Ubuntu SSO. Nautilus enhancements for managing folder sync preferences. Faster file sync speed. 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 transitioned to the launcher on first run.

In addition to that, the date and time indicator now has a real calendar widget and is included by default.

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.

UNE needs graphical driver acceleration to be able to run. Otherwise, you should be warned about missing them and will be logout and proposed to run standard ubuntu desktop session.

A list of required hardware is available there.


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

For 10.10 Beta, 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.

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 (removed a patch that disabled the network connections configuration).

Help would be appreciated in testing out:


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

There are a couple of known issues to watch out for


The server is now turned on and we request those with the available funds, to purchase our test package called Rick's Wallpapers. The cost is $1 and all profits will go to the Ubuntu Project itself. Please report any problems you have by running ubuntu-bug software-center from a terminal window.

The software-center got a "Featured" and "What's New" carousel in the Frontpage. It is faster and more responsive and contains a "History" feature that keeps track of what was installed, removed, or upgraded. Plugin support is added and technical items will not be shown by default.

Ubuntu Server Cloud images

cloud-init, the configurable initialization process for Ubuntu Server cloud images, has gained new features in Maverick Alpha 2, including pluggable hooks, ebsmount, ext4 support, and new stanzas in the cloud-config format.

Starting with Alpha3, cloud images instances can now manage their own kernel, and can upgrade kernels with apt. This is done by utilizing pv-grub provided by Amazon. The functionality is also provided on UEC hosts running Maverick Alpha 3 or later.

Starting with Beta, 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.


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

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.

Linux kernel 2.6.35

RC includes the 2.6.35-22.33 kernel which is based on the 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).
