Breaking changes

For a proxied request, e.g. Grafana’s datasource or plugin proxy:

  • If the request is cancelled, e.g. from the browser/by the client, the HTTP status code is now 499 Client closed request instead of 502 Bad gateway
  • If the request times out, e.g. takes longer time than allowed, the HTTP status code is now 504 Gateway timeout instead of 502 Bad gateway. Issue #47473

The change in behavior is that negative-valued series are now stacked downwards from 0 (in their own stacks), rather than downwards from the top of the positive stacks. We now automatically group stacks by Draw style, Line interpolation, and Bar alignment, making it impossible to stack bars on top of lines, or smooth lines on top of stepped lines. Issue #47373

The meaning of the default data source has now changed from being a persisted property in a panel. Before when you selected the default data source for a panel and later changed the default data source to another data source it would change all panels who were configured to use the default data source. From now on the default data source is just the default for new panels and changing the default will not impact any currently saved dashboards. Issue #45132

The Tooltip component provided by @grafana/ui is no longer automatically interactive (that is you can hover onto it and click a link or select text). It will from now on by default close automatically when you mouse out from the trigger element. To make tooltips behave like before set the new interactive property to true.
Issue #45053

Deprecations

/api/tsdb/query API has been deprecated and will be removed in a future release. Use /api/ds/query instead. Issue #45238
