2306 build reference

The Azure Stack Hub 2306 update build number is 1.2306.2.47.

Update type

The Azure Stack Hub 2306 update build type is Full. This build contains only important security updates.

The 2306 update has the following expected runtimes based on our internal testing:

  • 4 nodes: 8-28 hours
  • 8 nodes: 11-30 hours
  • 12 nodes: 14-34 hours
  • 16 nodes: 17-40 hours

Exact update durations typically depend on the capacity used on your system by tenant workloads, your system network connectivity (if connected to the internet), and your system hardware specifications. Durations that are shorter or longer than the expected value are not uncommon and do not require action by Azure Stack Hub operators unless the update fails. This runtime approximation is specific to the 2306 update and should not be compared to other Azure Stack Hub updates.

What's new

Changes

  • SQL RP V2 and MySQL RP V2 are only available to subscriptions that have been granted access. If you are still using SQL RP V1 and MySQL RP V1, it is strongly recommended that you open a support case to go through the upgrade process before you upgrade to Azure Stack Hub 2206.
  • This release provides support for Azure Stack Hub root certificate rotation. Previously, secret rotation did not rotate the root. You will be able to rotate the root certificate after installing the update. To do so, perform internal secret rotation on or before the next time you are notified via expiration alerts. Failure to rotate the root certificate and/or perform internal secret rotation might result in your stamp becoming unrecoverable.

Fixes

  • Fix to improve SLB throughput.
  • Fixed an issue that prevented access to the storage subsystem when scale unit nodes are rebooted.
