Changelog

All notable changes to BabelQueue.Sqs are documented here.

The format is based on Keep a Changelog, and this package adheres to Semantic Versioning. The envelope wire format is versioned separately by meta.schema_version (currently 1) — see the contract at babelqueue.com.

Unreleased

Added

  • OTel traceparent propagation (ADR-0028). SqsPublisher.PublishWithHeadersAsync(urn, data, headers, traceId) carries an out-of-band header carrier (e.g. a W3C traceparent from Telemetry.PublishAsync(…, headers, …)) as String MessageAttributes beside the frozen envelope (GR-1) — merged by SqsHeaders.Merge so the contract bq-* projection always wins a key collision, blank keys/values are skipped, and the SQS 10-attribute cap is respected. The consume side surfaces inbound attributes via public static SqsHeaders.Extract(message.MessageAttributes) → Dictionary<string,string> to hand to Telemetry.Wrap(handler, headers), so a consumer span becomes a true child of the producer span; with no traceparent it falls back to the v0.1 trace_id mapping (no regression). A header-less publish is byte-identical to before.

Changed

  • Require BabelQueue.Core 1.4.0 (the header-carrier seam version).

1.0.0 - 2026-06-12

Added

  • Initial release. An Amazon SQS transport on BabelQueue.Core + the AWS SDK for .NET v4 (AWSSDK.SQS): SqsPublisher (canonical-envelope SendMessage with the §3 MessageAttributes projection — bq-job/bq-trace-id/bq-message-id/ bq-schema-version/bq-source-lang/bq-created-at; FIFO group/dedup) and SqsConsumer (long-poll receive → URN-routed BabelHandlers → DeleteMessage; SQS-native visibility-timeout retry; attempts reconciled to ApproximateReceiveCount − 1, never lowering a runtime-incremented count; OnError/OnUnknownUrn hooks). net8.0, Roslyn analyzers (latest-recommended, warnings-as-errors); 16 xUnit tests (incl. the cross-SDK SQS binding conformance) run with a Moq-mocked IAmazonSQS (no AWS, no network). The envelope is unchanged (schema_version: 1); SQS is purely additive.
