The first beta of 'Oneiric Ocelot' — Ubuntu Linux 11.10 — has been released.
The new beta includes a trimmed down (1.5GB) DVD ISO (as well as the standard CD-sized ISOs) and the launch of 'Ubuntu Core' — a minimalist system designed to be used to create customised installations of the OS "for use in Board Support Packages, constrained or integrated environments, or as the basis for application demonstration images".
As well as the usual range of tweaks and updates, the beta improves the compatibility of 32-bit software on computers running the 64-bit edition of Ubuntu; this should ameliorate some of the headaches associated with running Flash on amd64-based systems, for example.
The beta marks the debut of Lubuntu: An Ubuntu derivative based on the super-light LXDE desktop environment
Beta 1 of Oneiric Ocelot runs version 3.0.3 of the Linux kernel and uses version 3.1.5 of the GNOME desktop environment.
