Release notes

- In 2023-01-01 Azure API, a hot fix is released and currently rolling out to fix this (bug)[https://github.com//issues/3481] and returns 400 error on PUT requests to "Base" or "Standard" parameters, allowing customers to still use "Basic" parameter in ManagedClusterSKUName with "Free" or "Paid" parameters in ManagedClusterSKUTier.

- Clusters on upgrade-channel nodeimage or nodeos-channel will no longer pull security updates through unattended upgrade. They will now get security updates through the weekly node image upgrade.
