Warning

Failure to rotate secrets on a regular basis can result in your data plane clusters entering an unhealthy state, and possibly redeployment of the Event Hubs on Azure Stack Hub resource provider. As such, it is critical that you proactively rotate the secrets used by Event Hubs on Azure Stack Hub. Secrets should be rotated after completing an install/update to a new release, and on a regular basis, ideally every 6 months.

Updates in this release

This release includes the following updates:

  • For Azure portal SDK developers, portal version 5.0.303.7361 is now supported.
  • Internal logging improvements for Event Hubs clusters.

Issues fixed in this release

This release includes the following fixes:

  • A fix to the upgrade order for Event Hubs clusters, to address an upgrade issue.
  • The cluster health and backup health check for Event Hubs clusters were not running when clusters were in "Upgrading" or "Upgrade Failed" state. The issue has been fixed in this release.
  • Fixed a bug causing usage records to contain the wrong quantity. Instead of cores, we were emitting capacity units (CU). Previously, a 1CU cluster would show 1 core in hourly usage. Users will now see the correct quantity of 10 cores for a 1 CU cluster in their hourly usage.
