Camel Quarkus 3.40.0 LTS lands as the project prepares for Quarkus 4
The integration runtime aligns with Camel 4.22.1 and Quarkus 3.40.1, while the project identifies 3.40 as the final feature line on Quarkus 3.
Apache Camel has released Camel Quarkus 3.40.0 as a long-term support line, aligning the integration stack with Camel 4.22.1 LTS and Quarkus 3.40.1 LTS. The release supports Java 17 and Java 21.
That alignment matters more than the version-number synchronization alone. The project says Quarkus 3.40 is the final feature release in the Quarkus 3.x stream, with Quarkus development shifting to 4.x. Camel Quarkus will follow in a future 4.x release stream, after required work in both Camel core and Camel Quarkus.
What changed in 3.40.0
The published release notes list work across AI integration, observability, native compilation, transport security and build hygiene. For LangChain4j users, the release adds a dedicated support extension for Quarkus LangChain4j build-time integration, expands embedding-store integration testing and adjusts ingestion metadata and document-ID handling. It also fixes Weaviate native compilation and embedding-store auto-detection behavior.
On observability, the release adds traceCustomIdOnly configuration for both Micrometer Observability and OpenTelemetry 2. The issue list also includes TLS registry handling for configured protocols and cipher suites, origin-restriction documentation for Vert.x WebSocket consumers, and fixes affecting native-image behavior.
The release artifacts include source archives plus CycloneDX SBOMs in XML and JSON formats, each accompanied by signatures and SHA-512 checksums.
The planning signal
For application teams, 3.40.0 is the stable Quarkus 3-based Camel line to evaluate while the upstream projects begin the Quarkus 4 transition. The announcement does not give a delivery date for Camel Quarkus 4.x and explicitly says work remains in both Camel core and Camel Quarkus.
That makes this release a boundary rather than merely another feature train: teams can adopt the new LTS stack on Java 17 or 21 now, while treating Quarkus 4 compatibility as future work rather than an immediate migration requirement.
