`ApiextensionsV1beta1Api()` not part of kubernetes 3.0.0

I am trying to test CRD and I re-installed the kubernetes module, version3.0.0 . Using ipyton 2.7

)$ sudo pip install --upgrade kubernetes

Since we have 4.0.0 out of alpha, I agree we can “forget the past” as it were. I do have another bug with the 4.0.0 client and the 1.8.0 server concerning this same API which I’ll open shortly. Thanks for your help.

You can install 4.0.0a1 via pip using this command:

pip install kubernetes==4.0.0a1 --upgrade

That’ll give you support for CRD. I agree it should be supported in 3.0.0, this is just a work around so you can continue with development.
