Is there any new rage power for unchained barbarian？

[KongShan]

I want to know the the rage power in books after Unchained is available to unchained barbarian or not?

Is unchained barbarian allways under control by the blog of two years before?

blog:

The unchained barbarian qualifies for any archetype that does not modify how the rage class feature operates (such as the urban barbarian archetype), and she is limited to any barbarian rage power that appears in Chapter 1 (including the rage powers on page 13)

Currently and officially the UBarb is stuck with that short list in unchained.

I believe the wording in unchained said this.

In books X, Y and Z only these rage powers work for unchained and here are some new ones. But any rage powers not in X, Y or Z are fine to be used with unchained.

PFS changed it to, Only the powers in X, Y and Z and the ones in this book are legal options.

So the real problem is to the PDT and writers and stuff they don't need to say, "this is available to unchained barbs" because the default is it's already available to them by being published. But if PFS will only legalize powers that say that then UBarb will never get more powers in PFS.

I may be very mistaken about this, but this is my understanding.
