Ubuntu 8.10 (Intrepid Ibex), released on 30 October 2008,[57][58] is Canonical's ninth release of Ubuntu. Support ended on 30 April 2010.[59] 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,[60] which allowed others to use a computer allowing very limited user rights (e.g. accessing the Internet, using software and checking e-mail).[61] The guest account had its own home folder and nothing done on it was stored permanently on the computer's hard disk.[62] Intrepid Ibex also included an encrypted private directory for users,[63] 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.[20][64]
