XBian is a small, fast and lightweight media center distribution for the Raspberry Pi, CuBox-i, Hummingboard and many more devices to come. It is based on a minimal Debian and therefor offers much of the same freedom as Debian offers.
Our slogan is “XBMC, the bleeding edge” as our main focus is delivering the fastest XBMC solution for various small form factor computers.
Just like Debian, XBian incoorporates rolling releases. This means that different from other distributions such as OpenELEC or Raspbmc, XBian doesn't release fixed images that often.
In contrast, XBian offers new package updates at least once a week. This means that new improvements and bugfixes are delivered quickly and easily.
When you keep your system updated, you will also start using new releases automatically. When all packages belonging to a new release are installed, XBian will also increase its own version.
So, you never need to reinstall!
This also means you can just install XBian Beta 2 and upgrade to XBian Release Candidate 2 in one go. Just as you can upgrade to XBian Stable 1 once it is released.
