Grafana 9.0.0 available, and downgraded back to 8.5.6 and back up... / 2022-06-15

I saw an upgrade of Grafana available, which turned out to be 9.0.0. When upgrading to 9.0.0 I get...

An unexpected error happened
TypeError: Object(...) is not a function

t@[..]public/plugins/grafana-clock-panel/module.js:2:15615
WithTheme(undefined)

So maybe the grafana-clock-panel plugin isn't compatible with 9.0.0 somehow.

Downgrading to 8.5.6 and reloading everything makes it work again.

Update: I checked the grafana-clock-panel plugin and noticed it hadn't been updated. So I did that update and retried grafana 9.0.0, and that made everything run smoothly again.
