Ubuntu 12.10 alpha 2 comes with Linux 3.5 based kernel

Canonical and the Ubuntu developers have published the second alpha release of Ubuntu 12.10, Quantal Quetzal. The new alpha release mostly has package updates to the distribution's components, including a Linux 3.5-rc4 based kernel (Ubuntu kernel 3.5.0-2.2), filesystem utilities (e2fsprogs, mdadm, autofs and btrfs-tools), Firefox and Thunderbird, and GTK+ (to the 3.5 series which will allow a number of GNOME 3.5 updates to take place).

Ubuntu Server has seen updates too, with Tomcat 7 replacing Tomcat 6, Chef 0.10.x, Ceph-0.57.2, MySQL 5.5.25 and updates to OpenStack to track the current "folsom" development milestones. The alpha 2 release also sees images for the Calxeda ARM servers being made available. There are also updates for Kubuntu, with KDE SC 4.9 Beta 2 included, and the experimental replacement of LibreOffice with Calligra Suite. Xubuntu sees a later Xfce (4.10) in use and updated Gimp and gThumb.

ISO images of the general desktop testing release are available for 32- and 64-bit x86 systems and 64-bit Mac systems. For all changes, known issues and links to further information and other images, consult the Alpha 2 Technical Overview. Development releases are meant for testing only and should not be used in a production or critical environment; users wanting a stable system should install Ubuntu 12.04 LTS, available from the Ubuntu.com download page.
