 ## Helm Chart Changes
 
-This release introduces an important change to the Helm chart configuration for the initializer job.
+This release introduces an important change to the Helm chart configuration for the initializer job and support for HPA and PDB.
+
+### New values
+
+Added Helm chart support for Celery and Django deployments for Horizontal Pod Autoscaler using `.autoscaling` fields under each section. And Pod Disruption Budget using `.podDisruptionBudget` for any of Celery Beat/Worker or Django deploy
