This release is rolling out to all regions - ETA for conclusion 2021-02-24 for public cloud.
Announcements
- The Azure Kubernetes Service pod security policy (preview) feature will be retired on June 30th, 2021.
- Once GA AKS will default to its new GPU specialized image as the supported option for GPU-capable agent nodes.
- Starting this week on 22 February 2021 (Azure China Cloud and Azure Government Cloud users will get this update in the following weeks), we will upgrade AKS clusters Calico network policy from Calico version v3.8.9 to v3.17.2 for cluster 1.20.2 and above. This upgrade will cause a breaking change to the default behavior of all-interfaces Host Endpoints. For customers that use Host Endpoints, and only these, this version brings a change. Please follow our guidance to apply the appropriate label and Global Network Policy if you want to keep the v3.8.9 default behavior of all-interfaces Host Endpoints.

Bug Fixes
- Fixed Auto Scaling issues with 1.19 Preview Clusters where no image is found for a distro to scale from.
- A previous release defaulted to Gen2 VHDs for Kubernetes versions below 1.18.0. This implicitly changed the Ubuntu version from 16.04 to 18.04 for users still below 1.18.0. This has been fixed and users will only receive Gen2 VHDs for Kubernetes versions greater than or equal to 1.18.0.
- Fixed AuthorizationFailed errors on cluster deletion operations to better expose to users.
- Fixed case sensivity problem when specifying "--os-type"
- Fixed an Error Handling issue when provisioning node pools with Ephemeral OS and a VM size with no cache disk.
- Fixed an issue with Azure Policy pods not getting scheduled with CriticalAddonsOnly taint GithubIssue
