Elsa 3.7.1 - Release Notes

Highlights

Hosting management - stable application instance names: Clustered hosts can now configure a stable, unique application instance name through ApplicationInstanceOptions.InstanceName or ApplicationInstanceOptions.InstanceNameEnvironmentVariable. This lets Azure Service Bus-backed change-token subscriptions and queues be reused across restarts instead of accumulating orphaned entities until the topic subscription limit is reached. (#7742)
Azure Service Bus entity-name safety: Long but otherwise valid configured instance names are shortened deterministically so Kubernetes pod names and similar deployment-provided identifiers remain stable while staying within the Azure Service Bus subscription-name limit. (c7a97c6412)

No breaking changes are expected. Deployments using Azure Service Bus for clustering/change-token transport should configure a stable per-instance name for each concurrently running host. For Kubernetes, set ApplicationInstanceOptions.InstanceNameEnvironmentVariable to an environment variable that contains a stable pod identifier such as HOSTNAME for StatefulSets or a Downward API-projected pod name for Deployments.
If no stable instance name is configured, Elsa preserves the previous random-name behavior and logs a warning when an explicitly configured environment variable is missing or empty.

Azure Service Bus startup reliability: Adds stable application instance-name configuration to prevent restart-driven creation of new per-instance Azure Service Bus change-token entities, addressing crash-loop/startup failures caused by exhausted subscription capacity. (#7732, #7736, #7742)
Configured instance-name validation: Rejects invalid configured instance names up front and trims explicit/environment-provided names before use. (1aef083815)
Long configured instance names: Shortens valid over-length names by preserving a prefix and appending a deterministic SHA-256 hash segment, keeping the resolved name stable across restarts. (c7a97c6412)

Added Elsa.Hosting.Management.UnitTests coverage for explicit instance names, environment-variable resolution, fallback random names, invalid values, deterministic shortening, and shell/module feature registration. (#7742, c7a97c6412)
