Karpenter v0.9.0 is the latest release since the project’s launch at re:Invent 2021. On January 7, 2022, Karpenter v0.5.4 added support for volume topology aware scheduling, enabling its use with stateful Kubernetes workloads. On March 14, 2022, Karpenter v0.7.0 made it easier to customize the compute provisioned by removing the need for custom EC2 launch templates, including when using Bottlerocket as the OS. With the v0.9.0 release, Karpenter fully supports workloads that use Kubernetes podAntiAffinity to achieve better availability by spreading pods across multiple hosts or availability zones.
