The Ubuntu developers are moving quickly to bring you the absolute latest and greatest software the Open Source community has to offer. The Maverick Meerkat Alpha 3 is the third alpha release of Ubuntu 10.10, bringing with it new features for the next version of Ubuntu.

This is an alpha release. Do not install it on production machines. The final stable version will be released on October 10, 2010.

Upgrading from Ubuntu 10.04 LTS

To upgrade from Ubuntu 10.04 LTS on a desktop system, press Alt+F2 and type in "update-manager -d" (without the quotes) into the command box. Update Manager should open up and tell you: New distribution release '10.10′ is available. Click Upgrade and follow the on-screen instructions.

To upgrade from Ubuntu 10.04 LTS on a server system: install the update-manager-core package if it is not already installed; edit /etc/update-manager/release-upgrades and set Prompt=normal; launch the upgrade tool with the command sudo do-release-upgrade -d; and follow the on-screen instructions.

New features in Maverick

Ubuntu

The GNOME base platform has been updated to the current 2.31 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.

Ubuntu Netbook Edition

The new Unity interface is now the default in Ubuntu Netbook Edition. This includes the global menu bar as part of the default interface. The date/time indicator now has a real calendar widget.

The standard photo management application has been switched to Shotwell.

Kubuntu

KDE Platform was updated to the 4.5 release candidate. The standard web browser is now Rekonq, a KDE browser based on Webkit.

Qt was updated to the current 4.7 beta release.

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.

Edubuntu

Edubuntu changes include the changes from Ubuntu. The edubuntu-artwork package has been split into smaller packages to improve future updates and reduce download sizes.

Software-Center

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

Linux kernel 2.6.35

Alpha 3 includes the 2.6.35-14.19 kernel based on 2.6.35 final.

This kernel includes new security enhancements. Of major note is the change 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″.

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.

Installation

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