**New Additions**

  * We will continue to cut over pieces of our architecture to use RabbitMQ exclusively for event-driven workloads
* Added **bitnami/rabbitmq** as a dependency
* Added **various handlers for documents processing**
  * These handlers are configurable via a new section the KOTS config form labeled "Vellum Documents Handlers"
  * This replaces the ffs deployment
* Added **[KEDA](https://keda.sh/) ScaledObjects and TriggerAuthentication** for autoscaling based on QueueLength in addition to typical CPU/Memory utilization metrics
* Added **HPAs for the django and django-task-handlers deployments** — configurable via the KOTS admin console
  * These will likely be replaced in favor of KEDA HPAs in a future release
* Added **annotation text area for Ingress object** for custom annotations

**Bugfixes**

* Cleaned up KOTS config form to only show cloud provider-specific options
* Removed `/grafana` path from Ingress object
