RBAC enforcement.
Topic message browser enhancements, including jump to timestamp and download results in JSON format.
Alert enhancements that added Slack and PagerDuty webhook notifications, a new Consumer lead alert, pause and resume global alerts actions, and fast navigation to Alerts features from the Alerts bell icon.
