- CDPD-36422: 1MB flow.snapshot freezes Safari

- OPSAPS-59597: SMM UI logs are not supported by Cloudera Manager
- Cloudera Manager does not display a Log Files menu for SMM UI role (and SMM UI logs cannot be displayed in the Cloudera Manager UI) because the logging type used by SMM UI is not supported by Cloudera Manager.

- OPSAPS-59553: SMM's bootstrap server config should be updated based on Kafka's listeners
- SMM does not show any metrics for Kafka or Kafka Connect when multiple listeners are set in Kafka.
- SMM cannot identify multiple listeners and still points to bootstrap
server using the default broker port (9093 for SASL_SSL). You would have to
override bootstrap server URL (hostname:port as set in the listeners for
broker). Add the bootstrap server details in SMM safety valve in the following

- CDPD-45183: Kafka Connect active topics might be visible to unauthorised users
- The Kafka Connect active topics endpoint
/connectors/[***CONNECTOR NAME***]/topics) and the Connect Cluster page on the SMM UI disregard the user permissions configured for the Kafka service in Ranger. As a result, all active topics of connectors might become visible to users who do not have permissions to view them. Note that user permission configured for Kafka Connect in Ranger are not affected by this issue and are correctly applied.
