COMPONENT NAME

• azure_rm_aks
• azure_rm_aks_info
• azure_rm_aksupgrade_info

ADDITIONAL INFORMATION

Breaking Changes:

azure_rm_aks:

• An agent_pool_profile now requires the 'mode' property

• upgrades.azure_aks_upgrades.agent_pool_profiles[n].kubernetes_version no longer returns an available upgrade version if the control plane needs updated first
