Quarkus 3.13 - OpenTelemetry Metrics, OpenTelemetry 1.39, TLS registry improvements and more...

A couple of months ago, we started some major work on the OpenTelemetry extension and you might have noticed that we skipped a few OpenTelemetry releases.

It is our pleasure to announce that this extensive work has landed in Quarkus 3.13 with these major changes:

The documentation has been updated:

In Quarkus 3.12, we introduced the TLS registry to simplify managing the TLS configuration and certificates.

This release introduces several additional improvements:

These new features are documented in the TLS registry guide.

We added several quarkus tls commands to the CLI to help with this new feature.

When working with REST Clients, you might want to have a closer look at the requests sent to the server. You often end up having to use a pass-through proxy, especially when dealing with HTTPS connections.

Quarkus 3.13 comes with a new feature that starts a pass-through proxy in dev mode. This proxy can be used as target for Wireshark to get the content of the requests sent by the client.

It can be easily enabled by setting quarkus.rest-client."client name".enable-local-proxy to true. When starting Quarkus, a log message will indicate you the port of the proxy.

This feature is only available with the Quarkus REST Client (the RESTEasy client doesn’t support it).

WebSockets Next, our next-generation WebSockets extension continues to be improved in each release.

One major improvement in this release for our Kotlin users is the support of Kotlin suspend functions.

ArC is the CDI implementation of Quarkus. It is at the core of Quarkus and is a critical piece of the Quarkus architecture, and is regularly improved to support more use cases or simplify existing ones.

Starting with Quarkus 3.13, it will be possible to use interceptors on producers and synthetic beans - which are very often used by extensions.

WithTestResource replaces QuarkusTestResource that is now deprecated.

The only change is the default behavior of the annotation: by default, it will restrict the resources to the annotated class. You can easily go back to the previous behavior by adding restrictToAnnotatedClass = false to your @WithTestResource annotation.

quarkus update will take care of this change for you and make sure it keeps the current behavior.

In some cases, people wanted to use dev mode for the Dev Services feature but wanted to disable live reload.

You can now easily do it by setting the quarkus.live-reload.enabled configuration property to false.

Quarkus CXF 3.13 was released and is now available in Quarkus Platform 3.13. Check Quarkus CXF 3.13.0 and Quarkus CXF 3.13.1 release notes for more information about what is new in this release.
