What's Changed

Lambda Durable Functions (Durable Execution) — full support for the AWS Lambda durable functions preview API (2025-12-01), including CreateFunction with DurableConfig, CheckpointDurableExecution, GetDurableExecutionState, GetDurableExecution, GetDurableExecutionHistory, ListDurableExecutionsByFunction, StopDurableExecution, and the three external callback ops SendDurableExecutionCallbackSuccess, SendDurableExecutionCallbackFailure, SendDurableExecutionCallbackHeartbeat. End-to-end verified against the official aws-durable-execution-sdk-python (1.5.0) and aws-durable-execution-sdk-java (2.44.13). A resume scheduler fires WAIT expiries, callback timeouts (Callback.Timeout / Callback.Heartbeat), and step-retry backoffs (NextAttemptDelaySeconds). State persists across restarts — the in-memory callback index is rebuilt from restored executions on boot and pending timers are re-armed. Reported by @youngkwangk.
S3 object tagging by versionId — GET/PUT/DELETE ?tagging honor the versionId query parameter, and PutObject / POST form upload now store the x-amz-tagging header against the resulting version rather than the object key, matching AWS's versioned-tagging semantics. Reported by @barrywilks7.
CloudFormation AWS::AppConfig::Application — create and delete provisioners for the AppConfig application resource type, wired into the existing CloudFormation dispatcher. Reported by @zmartinec.

DynamoDB gap closing — additional alignment work across DynamoDB validators and response shapes.
Lambda durable MaxItems pagination — ListDurableExecutionsByFunction, GetDurableExecutionState, and GetDurableExecutionHistory now return 400 InvalidParameterValueException when MaxItems is outside the AWS-documented [0, 1000] range, instead of silently clamping.
Lambda durable CheckpointDurableExecution validation — OperationUpdate entries with missing Id/Type/Action or with a Type outside EXECUTION/CONTEXT/STEP/WAIT/CALLBACK/CHAINED_INVOKE are rejected with 400 InvalidParameterValueException instead of being silently stored as garbage operations.
Lambda durable StopDurableExecution on terminal — calling Stop on an already-terminal execution returns 400 InvalidParameterValueException per the AWS-documented "Stops a running durable execution" contract.
