[wlug] JupyterHub 2.0 Is Out

Just saw this report <https://devclass.com/2021/12/02/jupyterhub-2/> on the new release of JupyterHub. This is the version of Jupyter designed to support multiuser deployments with proper access control. The new version supports role-based access control with delegation of admin responsibilities, so you can have group admins with control over their particular users but no privileges outside of that. For those new to Jupyter: <https://jupyter.org>.
