What’s new?

Dev extensions for observability

A lot of efforts have been put into simplifying the setup of dev resources for observability.

This includes Dev Services for:

  • Grafana

  • Jaeger

  • OTel

  • VictoriaMetrics DB

  • VictoriaMetrics Agent / scraper

Actually, they can be used in 3 different contexts:

  • Re-usable Dev Services (default)

  • Simple start/stop Dev Services

  • Single / plain per QuarkusTestResource dev resource

You can find more information about this new feature in this entry point to more detailed documentation.

Infinispan Cache extension

Quarkus has had a cache extension for a long time. This cache extension is backed by Caffeine by default.

We also had an Infinispan Client extension.

With the new Infinispan Cache extension, you can now use the cache extension approach and use Infinispan as a backend.

And, you know us by now, we baked a dedicated guide just for you. is our…​ next (tadam!)-gen WebSockets extension (both client and server).

It is experimental at the moment and we are making steady progress on it with each release.

In Quarkus 3.11, we added:

  • The ability to easily define WebSockets clients.

  • An initial version of the security integration (we will add more features in future releases).

quarkus:run and Dev Services

./mvnw quarkus:run is a convenient way to start your Quarkus application. It is now able to start Dev Services so that your favorite service can be started automatically as a container.


As for each release, this release comes with several new security features including:

  • Support for OIDC session expired page

  • The introduction of OidcRedirectFilter, which allows to customize OIDC redirects
