Your welcome .............
Thanks ..............
It's currently in its second round of public beta so the GM release is likely still a month or two out. Apple only sets specific release dates for major iOS releases (i.e. iOS 9.0.0, iOS 10.0.0, etc.).
Some recent dates to back this up.
9.1 - released 10/21/15
9.2 - released 12/8/15
9.2.1 - released 1/19/16
Could be towards the end of the month or early March but hard to say at this point!
