Minimum refresh interval now 10s?

I updated to Grafana 7.2.0 today and noticed that now my minimum refresh interval in the dropdown is now 10s not 5s (although I don’t know for sure this change was made in 7.2.0).

I could not see anything in the release notes about this? Why has this change been made?

I think I can still specify 5s on the URL but then the interface shows that the refresh is Off even though it’s refreshing every 5 seconds.

Setting the min_refresh_interval value in the .ini file to 5s has no affect on the interface options.
