• Added support for global default commit strategies (fallback when no explicit strategy is configured). (#7148)

Resilience / transient exception detection

• Added transient exception detection infrastructure and registration. (ca268c16ad) (#7161)

Workflow dispatch notifications

• Added new notifications emitted by the background dispatcher. (#7157)

Tenant task lifecycle & dependencies

• Introduced TenantTaskManager and dependency ordering support ([TaskDependency], TopologicalTaskSorter). (#7174)

🔧 Improvements

• Distributed runtime lock resilience: Polly retry around distributed lock acquisition (with transient exception detection), and safer lock release behavior. (#7161)
• Mediator background services: improved cancellation handling to avoid noisy failures. (ca268c16ad) (#7161)
• Xunit logging: suppress “no currently active test” errors from late background log writes. (ca268c16ad) (#7161)
• Small cleanups:
  • Make correlationId parameter non-optional in WorkflowExecutionContext constructor. (fa798b0a47)
  • Remove unused ClearCompletionCallbacks from WorkflowExecutionContext. (79a64e90fd)

🐛 Fixes

• Literal inputs: ActivityExecutionContext.TryGet(...) correctly handles Literal references by returning the literal’s value directly. (#7075)

🧩 Developer-facing changes

• Attribute usage expanded:
  • ActivityAttribute: now valid on classes, interfaces, and methods. (3778a14e54)
  • InputAttribute: now valid on properties and parameters. (3778a14e54)
  • OutputAttribute: now valid on properties, classes, methods, and return values. (3778a14e54)

🧪 Tests

• Added/expanded coverage for:
  • Host method activity registration & descriptor behavior. (#7172)
  • Distributed lock resilience (acquisition retries + release failure behavior). (#7161)
  • Literal input handling. (#7075)
  • Default workflow/activity commit strategy behavior. (#7148)
  • Workflow dispatch notifications. (#7157)
  • Tenant task dependency ordering / topological sorting. (#7174)
  • Transient exception strategy & detector behavior. (ca268c16ad) (#7161)
• Replace flaky Task.Delay with TaskCompletionSource for deterministic test synchronization. (2ff1693cd5)

🔁 CI / Build
