 Initial, limited, Raspberry Pi support was introduced in NetBSD 6.0. NetBSD 7.0 adds complete support for the board, along with introducing support for the quad-core Raspberry Pi 2 board.  Raspberry Pi 3 support was added for NetBSD 8, and backported to NetBSD 7 in July of 2017.  Initial, limited, Raspberry Pi support was introduced in NetBSD 6.0.

 ## Choosing a version  ## Choosing a version
   
 First, decide if you want to install a formal release (7.1), a stable branch build (netbsd-7, netbsd-8), or NetBSD-current.  Note that 7.1 predates Raspberry Pi 3 support.  For people who don't know how to choose among those, netbsd-8 is probably best.  First, decide if you want to install a formal release (7.2 or 8.0), a stable branch build (netbsd-7, netbsd-8), or NetBSD-current.  For people who don't know how to choose among those, 8.0 or netbsd-8 is probably best.
