Where is the PolyFit (2D) node?

Hi everybody,

I have a simple and maybe stupid question, where is the PolyFit (2D) node ?
It’s in the reference page on the website :
polyfit (2d)

But I cant find it in v4. Even in the new version beta26 …

Thank you by advance for your help.

Think it is in the addon pack?


If not can upload it for you when I am back at computer with vvvv

Ok thanks you very much, you are right, it was in the addon pack sorry for this question…
