v4.2 Update 6 - SaaS¶
03 Aug, 2026
This release includes the following enhancements and bug fixes that improve platform stability and reliability.
EKS Clusters with Only Fargate¶
You can now provision Amazon EKS clusters without managed node groups and configure Fargate profiles to run required blueprint components and operators. This lets you use AWS Fargate or Karpenter-managed node groups for compute without maintaining a dedicated managed node group for Rafay components, reducing infrastructure cost and operational overhead in a Karpenter-managed EKS architecture.
For more information, see EKS Clusters Without Node Groups.
Rafay MKS: Nameserver Overrides¶
Rafay MKS clusters now support optional Nameserver Overrides during day-0 provisioning and as a day-2 operation. This setting is useful in environments that use private DNS servers to resolve cluster domains and need to specify upstream nameservers for cluster DNS forwarding.
Configure nameserver overrides through the UI, API, Terraform, or CLI (RCTL).
For configuration details and examples, see Nameserver Overrides.
