Release notes

  • Bug Fix
    • 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.
  • Behavior Changes
    • 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.
    • Clusters with automatic node image upgrades (node-image auto-upgrade channel) will have nightly in-place patches turned off. You can set your own schedule (via upgrade schedules).
  • Component Updates
