Symfony Laravel Package

Fixed

• The bundle now boots in a real Symfony kernel under the babelqueue config key. BabelQueueBundle did not override getContainerExtension(), so on a real kernel boot the auto-derived extension alias (babel_queue) did not match the babelqueue config key and the kernel threw a LogicException. The bundle now returns BabelQueueExtension explicitly. (The prior tests exercised the extension directly and never booted a kernel, so they missed it.)

Internal

• Added a bundle integration test that boots a minimal test kernel registering BabelQueueBundle and asserts the serializer/middleware services resolve and the babelqueue config (default queue + URN message registry) is read.
• CI: release.yml now runs the ≥90% coverage gate (mirroring ci.yml).

Changed

• Aligned the Messenger serializer's transport headers to the canonical bq- projection. BabelQueueSerializer::encode() now emits bq-job (URN), bq-trace-id, bq-message-id, bq-schema-version, bq-source-lang and bq-attempts — the same bq- header set the Kafka/SQS/Pulsar bindings use — instead of the non-standard X-Babel-Urn / X-Babel-Trace-Id / X-Babel-Schema-Version (which also omitted source-lang, attempts and message-id). This makes Symfony-produced headers consistent with the rest of the ecosystem and lets a transport that maps serializer headers onto native broker headers (e.g. a Kafka Messenger transport) carry the §6-style bq- metadata, so a cross-language consumer can route on bq-job without decoding the body. The wire envelope is unchanged (schema_version: 1, byte-identical body) — interop has always been body-authoritative, so consumers that decode the body are unaffected; only the redundant transport-header names changed. Migration: if you read X-Babel-* headers off the transport, switch to the bq-* names. Note: for transports where the native projection is owned by Messenger itself (AMQP type, SQS MessageAttributes), routing stays body-authoritative regardless of these serializer headers.

1.0.0 — the public API is now SemVer-stable: breaking changes require a MAJOR, following the deprecation policy. The wire envelope is unchanged (schema_version: 1). Full reference at babelqueue.com.

Changed

• Require babelqueue/php-sdk ^1.0.

Internal

• CI runs PHPStan (level 9) over src and enforces a >=90% line-coverage gate (bin/check-coverage.php); added a DI test for the bundle extension. Decode now hardens mixed JSON values (URN via the core EnvelopeCodec::urn, guarded attempts/trace_id) — no behaviour change for valid envelopes.

Added

• Messenger\TracePropagationMiddleware — automatic trace_id propagation: while a received message is handled, any follow-up message dispatched on the bus inherits its trace_id (unless it pins its own stamp or implements HasTraceId). Registered as babelqueue.messenger.trace_middleware.

Changed

• Raise the core dependency to babelqueue/php-sdk ^0.3.

Notes

• The version jumps to 0.3.0 to align the PHP packages (php-sdk, laravel, symfony) on one version line. The serializer/codec foundation below shipped across 0.1.0–0.2.0; this changelog began per-version sections at 0.3.0.

Added

• Messenger\BabelQueueSerializer — a Symfony Messenger transport serializer that encodes/decodes the canonical BabelQueue envelope via the shared core codec (babelqueue/php-sdk), so Symfony interoperates with the other SDKs.
• Contracts\PolyglotMessage — message contract (getBabelUrn(), toPayload(), fromBabelPayload()).
• Messenger\MessageRegistry — URN → message-class map for decoding.
• Messenger\Stamp\BabelTraceStamp — carries trace_id through the pipeline; attached on decode, honoured on encode (trace continuation).
• Redelivery ↔ attempts bridge (Messenger RedeliveryStamp ⇄ envelope attempts).
• BabelQueueBundle + DI: registers the serializer as babelqueue.messenger.serializer, configured under the babelqueue key.

Notes

• Pre-1.0: the public API may change before the 1.0.0 tag.
• Requires PHP ^8.2, babelqueue/php-sdk ^0.1, and Symfony ^6.4 | ^7.0.
• Routing/worker/retry remain Messenger's responsibility; this package only owns the wire format.
