Q: update 10.9.1 not showing up in 'software update'

Late 2013 MBA

fully updated on 10.9

keynote, pages, numbers updated also

all firmwares and camera raw updates complete

basically it is fully update BUT is not offering 10.9.1 at all

I tried to push each of the offered versions of 10.9.1 to the machine via task server also but the machine wont take any of them

so that plus the fact that the update to 10.9.1 is not even offered to me in software update is very confusing

does any one have any advise for me?
