Whilst it may not have been totally clear sure with the reasons others have mentioned that this is the official release. There is no longer a Beta section in Samsung Members. seems to be running pretty well but I am still monitoring.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
