I would like to use: https://github.com/metabase/metabase/pull/4123, which has been recently added to master but as far as I can tell still isn’t in the stable. Is there a guide on how can I deploy the latest master on my metabase install?
So, you can currently do this with normal dashboards within Metabase (here's the documentation, under the heading Configuring a dashboard through its URL), but I think it was removed from public dashboard links, partly because we were concerned it would be a way for people to accidentally or intentionally clobber your server. Once we have caching, we should hopefully be able to add this back in for public links.
You can follow specific releases through our milestones github.com/metabase/metabase/milestone
Things will move in and out of milestones, so you shouldn’t treat them as a hard commitment that a specific issue will ship at a specific time. We occasionally find that somethings are more complicated than anticipated and move them forward.
@Dizzyfish I can always configure the device to automatically reload every X seconds (this is what I’ve done), but it feels like a feature that would work well for an embeddable / public dashboard.
