Raspbmc is a build of XBMC for the Raspberry Pi and the June update has brought us lots of updates and changes. There is an updated firmware / kernel and fixes for Live TV, improved setting options, a new XBMC skin and support for the Raspberry Pi camera addon. To get the update just reboot you’re Pi and the automatic update processes will kick in.

Another two mirrors have joined the Content Delivery Network which means faster updates and installs. The project is very weak for downloads in Asia and would very much appreciate a mirror to help offer users a good quality update and installation experience there.
