Release 2026-06-11

Amazon.Lambda.DurableExecution (0.0.1-preview)

• Thread CancellationToken into every user Func accepted by IDurableContext (StepAsync, RunInChildContextAsync, WaitForCallbackAsync, WaitForConditionAsync). The token links the caller-supplied cancellation token with an SDK-owned workflow-shutdown signal so user step bodies unwind cleanly when the workflow is being torn down. Cancellation via the linked token is not checkpointed; user-thrown OperationCanceledException unrelated to the linked token continues to be treated as a normal step failure.
• Initial preview release of the Durable Execution SDK for .NET. Build long-running Lambda workflows with automatic checkpointing via , , , , and on .
• Add WaitForConditionAsync polling primitive: IDurableContext.WaitForConditionAsync, IConditionCheckContext, WaitForConditionConfig, IWaitStrategy, WaitDecision, WaitStrategy factory (Exponential/Linear/Fixed/FromDelegate), and WaitForConditionException with AttemptsExhausted and LastState
