Welcome to Karmic Koala
Alpha 5, which will in time become Kubuntu 9.10." The standard release announcement contains no new information while the release notes have been slightly updated to reflect the introduction of a new development version of GNOME (2.27.91 as opposed to 2.27.4 in Alpha 4) and a newer kernel (version 2.26.31-rc8 updated from 2.26.31-rc5 in Alpha 4). Otherwise they contain the same feature list as the previous release notes: updated packages, Ubuntu Enterprise
Cloud, a new file sharing service, new Intel video driver architecture, GCC 4.4 as the default compiler, ext4 as the default file system and GRUB 2 as the default bootloader.
