Breaking changes
Alert notifications to Microsoft Teams now use Adaptive Cards instead of Office 365 Connector Cards. Issue #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.. 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
