Ubuntu 8.10 (Intrepid Ibex), released on 30 October 2008, was Canonical's ninth release of Ubuntu. Support ended on 30 April 2010. Ubuntu 8.10 introduced several new features including improvements to mobile computing and desktop scalability, increased flexibility for Internet connectivity, an Ubuntu Live USB creator and a guest account, which allowed others to use a computer allowing very limited user rights (e.g. accessing the Internet, using software and checking e-mail). The guest account had its own home folder and nothing done on it was stored permanently on the computer's hard disk. Intrepid Ibex also included an encrypted private directory for users, the inclusion of Dynamic Kernel Module Support, a tool that allows kernel drivers to be automatically rebuilt when new kernels are released, and support for creating USB flash drive images.
