+The exclusion of Edge and MAAS clusters in kCh calculations is implemented in the Palette release 4.5.c and does not
+revise historical data. Therefore, it is normal to notice a drop in your resource usage after Jan 18th, 2025 for Palette
+SaaS if you have Edge or MAAS workloads in your project.
+
+Even though your resource usage in the past may have included Edge and MAAS clusters, we have never charged you for
+resource usage by Edge and MAAS clusters since you provide the infrastructure for those clusters yourself.
