Security Notices​

Palette Enterprise​

Breaking Changes​

Features​

  • EKS Pod Identity is now a supported authentication method for AWS cloud accounts. This secure authentication mechanism allows Kubernetes pods to assume IAM roles with temporary, automatically refreshed credentials, eliminating the need for long-lived AWS credentials.

    This method is only available for self-hosted Palette and Palette VerteX instances deployed on Amazon EKS clusters. Refer to the Add AWS Accounts guide for more information.

  • Cluster profile variables now support the multiline input type and the Base64 format. This improvement allows users to leverage cluster profile variables for use cases such as saving multiline YAML specifications and storing encoded keys for use during cluster creation.

Improvements​

  • Project tags are now displayed in the Project Overview page and the Tenant Admin > Projects page in Palette. This improvement allows users to identify projects based on their tags. Refer to the Project Tags section for more information.

  • Palette now provides the ability to upgrade the vCluster version of your virtual clusters, allowing you to leverage newly introduced features without having to create new cluster groups or migrate workloads. Refer to the Upgrade Cluster Groups guide for further information.

  • Palette has now implemented a mechanism for evacuating and migrating the control planes for MAAS clusters using LXD VMs, reducing high-availability risks during host repaves. This improvement is critical for Day-2 lifecycle operations such as upgrades or repaves.

  • The Palette Management Appliance and VerteX Management Appliance now include the latest Terminal User Interface (TUI). For more details, refer to Initial Edge Host Configuration with Palette TUI.

  • Certificate renewal for clusters provisioned using Palette Optimized K3S and RKE2 can now be triggered externally from Kubernetes. This is applicable for both Edge and public cloud clusters.

Bug Fixes​

  • Fixed an issue that caused Palette UI errors related to YAML marshalling when accepting cluster profile updates for cluster profiles configured using the Spectro Proxy pack.

  • Fixed an issue that prevented ipclaim resources from being deleted when repaving VMware clusters.

  • Fixed an issue that prevented the Palette UI from displaying metrics for EKS clusters due to incorrect security group rules.

  • Fixed an issue that prevented rotated IAM keys in AWS cloud accounts from being updated on deployed AWS clusters.

Edge​

info

The CanvOS version corresponding to the 4.8.6 Palette release is 4.8.1.

Improvements​

  • The Terminal User Interface (TUI) is now always enabled and features a new landing page that displays system information. It also adds support for configuring Virtual Local Area Networks (VLANs). The stylus.includeTui flag in user-data has been deprecated as a result of these changes. For more details, refer to Initial Edge Host Configuration with Palette TUI.

  • CanvOS now provides support for FIPS-compiled Ubuntu 22.04. This is important for users who want to enforce FIPS 140-3 compliance.

Bug Fixes​

  • Fixed an issue that caused pack reconciliation to fail in locally managed Edge clusters provisioned with cluster profiles containing duplicate packs.

VerteX​

Features​

  • Includes all Palette features, improvements, breaking changes, and deprecations in this release. Refer to the Palette section for more details.
