Link discussing new features in more detail: https://grafana.com/docs/grafana/latest/whatsnew/whats-new-i...

Biggest change in the release, IMO: https://grafana.com/docs/grafana/latest/alerting/unified-ale...

Does the new alerting engine support template variables in queries [1]? Many complained about this.

Hmmm. Grafana Live looks interesting. Does this mean Grafana now hosts and serves timeseries data [1], like InfluxDB? Or is this only temporal, only for events, alerts, etc? [1] https://grafana.com/tutorials/stream-metrics-from-telegraf-t...

From what I understood, the data is not persisted anywhere, but just pushed to currently open dashboards. I could be wrong though..

Thanks. Yes, that does seem to be the case. I found this old design doc [1] and discussion. Nifty feature for IoT to have more responsive alerts.

right now it is streamed to the UI (not persisted), though we have hooks in place to allow persisting the live data into Grafana cloud offerings.

a few days ago our PR for websocket output in telegraf was merged, and available in v1.19.0-rc0 :)

The relatively new Node graph visualization can't be used with any datasource, even if you select the data to fit the model of the two nodes and edges data frames, because it needs a special meta property to work.

EDIT: it seems it is no longer the case, I will test it :

Also it would be nice if an embedded panel could select its own time range.
