June 2026 monthly summary for grafana/tempo-operator: Delivered CRD stability improvements and reduced validation friction for Tempo resources, enabling smoother deployments and multi-tenant usage. Key changes: make managementState and tenants.mode optional in the CRD while preserving defaults. This fix prevents validation errors from kubeconform and API server defaulting from rejecting valid TempoStack/TempoMonolithic resources, maintaining existing behavior (managementState defaults to 'Managed', tenants.mode to 'static'). Impact: improved deployment reliability, reduced onboarding friction, and fewer support tickets related to CRD validation. Technologies/skills demonstrated: Kubernetes CRD design and defaulting, kubebuilder annotations, CRD schema validation, and API server behavior understanding.
