Breaking changes

When parsing Elasticsearch query responses using template variables, each field gets named after the variable value instead of the name. For example, executing a terms aggregation on a variable named $groupBy that has @hostname as a value, the resulting column in the table response will be @hostname instead of $groupBy Issue #36035

Azure Monitor data source no longer supports different credentials for Metrics and Logs in existing data sources. To use different credentials for Azure Monitor Logs, create another data source. Issue #35121

Existing Azure Metrics Logs queries for Log Analytics Workspaces should be backward compatible with this change and should not get impacted. Panels will be migrated to use the new resource-centric backend when you first edit and save them.

Application Insights and Insights Analytics queries are now read-only and cannot be modified. To update Application Insights queries, users can manually recreate them as Metrics queries, and Insights Analytics are recreated with Logs.
