• deploy/00crds.yaml (3123-3125) This change from a string to an array of strings for `ipAddress` is a breaking API change. Make sure all controllers and client code that reads or writes this field are updated to handle the new array format. Consider adding migration logic or version-specific handling to maintain backward compatibility with existing resources.
• deploy/installer.yaml (3123-3125) This change modifies the `ipAddress` field from a string to an array of strings, which is good for supporting multiple IPs per NIC. However, ensure that any code consuming this field is updated to handle the new array format to prevent runtime errors. Consider adding migration logic if there are existing resources using the old format.
• k8s/migration/api/v1alpha1/vmwaremachine_types.go (92-92) Changing `IPAddress` from `string` to `[]string` is a breaking API change. Make sure to update all code that uses this field, including any code that might be unmarshaling JSON into this struct. Consider adding a migration path or version bump if this API is already in use.
