ATT Note2 Model Number: SGH-I317ZWAATT Not Compatible with Towelroot?

[AC Question]

I have an unlocked ATT Note 2 that I would like to root. Model Number: SGH-I317 I317ZWAATT
I downloaded Towelroot and received a message that my phone is not compatible.
Any ideas when this model will be available to root with the Towelroot software?
