Summary

Added important note about removal of SigV4 authentication in Core Prometheus plugin starting in version 12

Security assessment

Change documents migration to a new plugin but provides no evidence of security vulnerability remediation. Removal of SigV4 authentication appears to be a planned deprecation/feature change without security justification.

+###### Important
+
+Starting in Amazon Managed Grafana version 12, SigV4 authentication support in the Core Prometheus plugin has been removed. All Amazon Managed Service for Prometheus data sources that were previously using the Core Prometheus plugin are automatically migrated to the Amazon Managed Service for Prometheus plugin. Any dashboards using these data sources are automatically updated to reflect this change. See [Connect to an Amazon Managed Service for Prometheus data source](./amazon-prometheus-data-source.html).
