This version improves DDC lifecycle management and reliability, including graceful shutdown rollout for compute groups, configurable readiness probe policies, DCR mTLS support, and clearer DDC health reporting. It also enhances Helm chart configuration and adds several validation and stability fixes.

Features & Enhancements

• DDC compute groups support graceful shutdown rollout for rolling updates, scale-down, and delete operations, with a sentinel compatibility gate and fallback to the normal StatefulSet flow for unsupported images. [feat] Backport graceful shutdown rollout #502
• Support configurable readiness probe policy for DorisCluster and DorisDisaggregatedCluster pods. support configurable readiness probe policy #486
• Support mTLS for DCR. [feature](tls) support mTLS for DCR #483
• Split DDC compute group service into an internal headless service and an external service for smoother upgrades and traffic switching. split CG service into internal headless and external service #484
• Helm chart adds support for component-level secrets. [feat] helm-charts: add support for secrets #465
• Helm chart exposes serviceAccount configuration for deployed pods. Feat: Expose service account from the helm chart #470

Bug Fixes

• Fixed DDC MetaService health aggregation so MetaService degradation is reflected in cluster health status. fix：DDC meta service health aggregation #500
• Fixed nil map panic in CompareConfigmapAndTriggerRestart when dcr.Annotations is nil. fix: fix nil map panic in CompareConfigmapAndTriggerRestart when dcr.Annotations is nil #493
• Fixed FE endpoint address JSON tag and regenerated DorisCluster CRDs. fix: FE endpoint address JSON tag #497
• Reject invalid DorisDisaggregatedCluster FE specs where feSpec.replicas < feSpec.electionNumber. fix: reject invalid disaggregated FE replicas #498
• Reject DDC compute group storage template changes before applying immutable StatefulSet volume claim templates. fix: reject ddc compute group storage template changes #496
• Fixed the default storage_root_path in the DorisDisaggregatedCluster BE Helm config. fix #477

Improve & Reliability

• Reject using the built-in admin account as the operator management user in DorisCluster and DorisDisaggregatedCluster webhooks. improve: reject admin management user in webhooks #499
• Add pull request checks for Go formatting, vet/lint checks, operator build, and generated manifests/artifacts. Add pull request checks #501
