Announcements

• Windows 2019 will be retired in Kubernetes v1.33 and above (ETA March 2026). Customers should upgrade to Windows 2022.
• Kubernetes 1.24 is being deprecated end of July 2023 and support will transition to our platform support policy.
• Starting Kubernetes 1.25, the default cgroups implementation on AKS nodes will be cgroupsv2. Older versions of Java, .NET and NodeJS do not support memory querying v2 memory constraints and this will lead to out of memory (OOM) issues for workloads. Please test your applications for cgroupsv2 compliance.
• A known issue in Kubernetes version 1.24 is causing name resolution failures in Windows pods. Customers experiencing this issue should upgrade their cluster to Kubernetes version 1.25.
