 == Redpanda Cloud vs Self-Managed feature compatibility
 
+Because Redpanda Cloud is a fully-managed service that provides maintenance, data and partition balancing, upgrades, and recovery, much of the cluster maintenance required for Self-Managed users is not necessary for Redpanda Cloud users. Also, Redpanda Cloud is opinionated about Kafka configurations. For example, automatic topic creation is disabled. Some systems expect the Kafka service to automatically create topics when a message is produced to a topic that doesn't exist. (You can create topics in Redpanda Cloud on the *Topics* page or with `rpk topic create`.)
+
+New clusters in Redpanda Cloud generally include functionality added in Self-Managed versions immediately. Existing clusters include new functionality when they get upgraded to the latest version. 
+
 Redpanda Cloud deployments do not support the following functionality available in Redpanda Self-Managed deployments:
 
-- FIPS-compliance mode
-- Data transforms (currently in beta for Redpanda Cloud)
-- Remote Read Replicas (currently in beta for Redpanda Cloud)
-- Kafka API OIDC authentication (however, Redpanda Cloud does support xref:security:cloud-authentication.adoc#single-sign-on[user authentication to an organization with SSO])
-- Kerberos authentication
-- Redpanda debug bundles
-- Redpanda Console topic documentation
-- Setting `auto_create_topics_enabled=true`
-- Admin API
