The latest released version of zero-to-jupyterhub-k8s, v1.2.0, has JupyterHub==1.5.0 as requirement. This version requirement has been updated directly in master a couple of weeks ago to the newer JupyterHub 2.0.0, but no new release has been made since.
Is there a plan to release a new version using JupyterHub in the short term? It would be great to have a fixed snapshot of the repo using the new JupyterHub’s version instead of having to use master branch, which changes frequently.
