+| When using content bundles built from cluster profiles using PXK-E as the Kubernetes layer to deploy an Edge cluster, some images in the Kubernetes layer fail be loaded into containerd due to image signature issues, leading to deployment failure.                                                                                                                                                                                                                                                                                                                                    | Remove the `packs.content.images` from the Kubernetes layer in the pack configuration before building the content bundle. These components are already included in the provider image and do not need to be included in the content bundle.                                                                                                                                                                                                                                                                                                                                                                     | December 13, 2024  | Edge                         |
 | For Edge airgap clusters, manifests attached to packs are not applied during cluster deployment.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          | Add the manifest as a layer directly instead of attaching it to a pack.

 | In some cases, the differential editor incorrectly reports YAML differences for customizations not created by you. The issue is more common when items in a list or array are removed. Clicking the **Keep** button when non-user-generated customization is the focus causes the button to become unresponsive after the first usage.                                                                                                                                                                                                                                                    | Skip differential highlights not created by you.

 | Palette fails to provision virtual clusters on airgapped and proxy Edge cluster groups. This error is caused by Palette incorrectly defaulting to fetch charts from an external repository, which is unreachable from these environments.                                                                                                                                                                                                                                                                                                                                                 | No workaround.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  | November 9, 2024   | Virtual Clusters             |
