### Breaking changes

Alert notifications to Microsoft Teams now use Adaptive Cards instead of Office 365 Connector Cards. Issue [#53532](https://github.com/grafana/grafana/issues/53532)

Starting at 9.1.0, existing heatmap panels will start using a new implementation. This can be disabled by setting the `useLegacyHeatmapPanel` feature flag to true. It can be tested on a single dashbobard by adding `?__feature.useLegacyHeatmapPanel=true` to any dashboard URL. Please report any [heatmap migration issues.](https://github.com/grafana/grafana/issues/new/choose). The most notable changes are:

- Significantly improved rendering performance
- When calculating heatmaps, the buckets are now placed on reasonable borders (1m, 5m, 30s etc)
- Round cells are no longer supported
  Issue [#50229](https://github.com/grafana/grafana/issues/50229)

### Plugin development fixes & changes

- **Plugins:** Only pass `rootUrls` field in request when not empty. [#53135](https://github.com/grafana/grafana/pull/53135), [@wbrowne](https://github.com/wbrowne)
