Announcements
- Kubernetes 1.25 is being deprecated at the end of January 2024 and support will transition to our platform support policy.
- No new clusters can be created with Azure AD Integration (legacy). Existing AKS clusters with Azure Active Directory integration will keep working. All Azure AD Integration (legacy) AKS clusters will be migrated to AKS-managed Azure AD automatically starting from December 1st, 2023. We recommend updating your cluster with AKS-managed Azure AD before December 1st, 2023. This way you can manage the API server downtime during non-business hours.
