The ARM team is closing on the F-13 release for ARM now, with
hopefully a release shortly. I suspect it will be discussed more in
depth at FUDCon as I believe most of the people involved with ARM are
going to be there. Straight after the F-13 release we'll be moving on
to getting Fedora 14 release built as soon as possible. This should
hopefully be gearing up with the arrival of Panda Board soon
apparently :-)

What happened with the naming of the XO 1 and 1.5 initial release
numbering? They weren't originally in sync.

What about bumping the major release to 14 for the stable XOs and to
12/13 for the 1.75 reflecting the Fedora release that its based upon
and then use the usual 14.1 14.2 etc that way there's no confusion
based on the underlying os ages and allows the usual point releases.
