Rebuilding Marten Projections Without Downtime with Wolverine 6.51 Warm-up Nodes

Wolverine 6.51 adds a warm-up node role for blue/green deployments. New nodes join the cluster only to rebuild new projection versions in Marten or Polecat, without handling messages or subscriptions. Combined with versioned projections and a side-effect gate, teams can catch up read models before switching traffic. This is a practical path to zero-downtime releases for event-sourced systems.

Serverless Wolverine Gets a Transactional Outbox in Wolverine 6.51

Wolverine 6.51 adds the DurabilityMode.ServerlessWithOutbox mode, letting handlers running on Cloud Run, AWS Lambda or Azure Functions keep the transactional outbox without always-on background agents. An externally triggered durability pass recovers messages that failed to send, and push receivers accept broker deliveries over HTTP. It is a useful option for teams on tight serverless budgets.
