Upgrade to jupyterhub 4?

[consideRatio]

In the main branch, we have jupyterhub 4, but we have jupyterhub 1 in the latest release (0.2.0). Can we upgrade straight from jupyterhub 1 to jupyterhub 4? If so, I suggest we go for it.

I have the same question. Currently running on TLJH 0.2.0 but would love try out jupyterhub 4.

It's tested in the jupyterhub suite and should be supported. It's a disruptive upgrade (the 1->2 transition means all user servers must be restarted and any API-issued tokens will be revoked), but for most tljh use cases, the restart-everything should be the only issue folks need to deal with.

Thank you @minrk, I conclude we should upgrade straight to JH 4 then, and let users know about this.
