Notify users about upcoming grafana update

Is there any straightforward way to notify grafana users through the interface about upcoming grafana-server update (supposedly not all grafana users have notification channels or alerts configured)?

Something like pop up window or maybe something less annoying.

Thank you!

Popup from within grafana or something else?

Yes, something like that: popup or hiding panel from within grafana.

I believe someone already solved such problem - notify all grafana users company-wide
