AIR

I noticed in my account when updating protools that there is a file named - AIR Creative Collection 11.1 Installer for PT 11.x (Mac) (2.3 GB)



Is this something I need to get? I thought that http://ift.tt/WHj9Jf were handling Air now stuff now. SO confused. Is this an old file? Wish they were dated so I can see when it was put there.



Air CC is velvet hybrid etc right?
