If you make a library that is only 5.6.5 right now you are kinda throwing us under the Native Access bus.
Except for the large amount of users that could not download 5.6.5 via SC and were sent to NA...Nope. Because you can still download 5.6.5 update from your account or Service Center and not via NA. This only applies to NI libraries, really. Not 3rd parties.
