Welcome to Oneiric Ocelot Alpha 3, which will in time become Ubuntu 11.10.

Pre-releases of Oneiric Ocelot are *NOT* encouraged for anyone needing a stable system or anyone who is not comfortable running into occasional, even frequent breakage. They are, however, recommended for Ubuntu developers and those who want to help in testing, reporting, and fixing bugs.
