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).
