Latest updates

🟢 WG - Quarkus 4

Work on Quarkus 4 saw progress with CI rework for the 4.0 branch. The team improved the Event bus and updated Vert.x configuration, including Buffer#getByteBuf usage. We also revisited the default value for quarkus.http.use-semicolon-as-query-param-delimiter.

🟢 WG - Quarkus Data

The team resolved issues with AutoId and @Transactional in Hibernate Reactive Panache, also addressing duplicate feature name conflicts. Our focus now turns to redesigning core data operations, fleshing out shortcut types, and integrating with Spring Data extensions.

🟢 WG - Observability.Next

The team resolved issues with OpenTelemetry context loss in blocking @ConsumeEvent messages and improved Vert.x event bus span correlation. We also addressed the HttpServerMetricsTagsContributor for connection resets. Current efforts focus on OpenTelemetry declarative configuration, propagating OTel trace context, and exploring observability guidance with AI.

🟢 WG - Convert quarkus.io to Roq

This should be taken with a pinch of salt because a few parts of the site aren't being generated in the roq version, like the author pages. (I have a fix, I just haven't pushed it.) But, with that caveat, I had Claude analyse recent CI runs of the converted and unconverted site. And the results are ....

Generator	Step	Samples	Avg	Range
Jekyll	"Build Jekyll site"	12 runs	102s	99–107s
Roq	"Build with Maven"	3 runs	33s	31–37s

In CI, the site build is 3x faster with Roq than it was with Ruby. 🎉

Page serving in CI is also faster, but I don't have enough data to quantify the impact of that yet.

🟢 WG - Modularity (JPMS) and JLink

The team migrated JAR file writing to smallrye-common facilities and made several JLink adjustments. We also resolved a SmallRye and MicroProfile config version conflict that was impacting Java module builds. The focus now is on new Archive APIs in smallrye-common-io and refining manifest copying.

🟢 WG - Unified Event Bus

The team improved the Event bus and addressed OTel context loss for @ConsumeEvent messages. We resolved issues with @RunOnVirtualThread for Signal receivers and added configurable concurrency limits. Efforts now focus on propagating security identity and OTel trace context to Signal receivers.

🟢 WG - Spring-Style Testing

Work focused on making the @SpringBootTest annotation functional. All related issues are now closed, and no new tasks were added during this period.

(This status update was automatically generated using AI.)

🟢 WG - Dev Star

The team added initial aesh extension support, along with AI skills for quarkus-quartz, websockets-next, and config-yaml. We also fixed Dev UI workspace scrolling and improved French translations. Current work involves refining Dev UI extension card text support and logging Dev MCP endpoint paths.

🟢 WG - AOT Support

The team introduced the first version of aot-jar packaging, making it the default when AOT is enabled. We also completed several small adjustments for JLink integration. No new issues were reported.

(This status update was automatically generated using AI.)

🟢 WG - Agentic Foundation and LangChain4j Next

The group addressed an NPE with shared ChatMemory and fixed the agentic module in native mode. We also improved observability documentation for Quarkus Langfuse integration. These areas remain a key focus for the team.

(This status update was automatically generated using AI.)

🟢 WG - Dev Services Lifecycle

The group migrated observability to the new dev service model. We also addressed the ObservabilityJsonRPCService failure that occurred when the LGTM dev service was disabled.

(This status update was automatically generated using AI.)

🟢 WG - Quarkus Terminal

The team added initial aesh extension support, including SSH and websockets. They also replaced picocli with aesh for CLI parsing. No new issues were opened this period.
