If you had the CC-licensed LR version you’d get the new features right away.
Since you have the serial-number-licensed version, you’ll get Dehaze when LR 7 comes out in a year or so, along with any other new features that the CC folks have gotten.
I was not sure if I could get this update. You have answered my question
I have recently purchased Lightroom 6.1 my question is can I update this program to in the Dehaze Slider
Have a look in the thread - Invoke the Dehaze effect in LR6 a couple of options for using DeHaze in LR 6 are given there.
