What’s new?

Support for AWS Lambda SnapStart

Quarkus 2.15 brings support for AWS Lambda SnapStart.

This has already been announced in details in a previous blog post.

See the dedicated guide for more information about how to use AWS Lambda SnapStart with Quarkus.

New gRPC implementation

The gRPC extension has been rewritten to use a new Vert.x-based gRPC implementation.

Moreover @InjectMock is now working for gRPC Mutiny clients.

Federation support for SmallRye GraphQL

The SmallRye GraphQL extension now supports enhancing your GraphQL API with metadata needed to be able to expose it via a Apollo Federation gateway. This is achieved via annotations in the io.smallrye.graphql.api.federation package. See for general information about Federation or for an example.

Redis - Search group

Since the introduction of the new Redis extension, a lot of new commands were added from version to version.

It is now commands for the search group which makes its apparition in Quarkus.

@ClientQueryParam for Reactive REST Client

Using the Reactive REST Client, it is possible to add query parameters to a request with the @ClientQueryParam annotation.

It is described in details in the Reactive REST Client guide.

Filtering by named queries in REST Data with Panache extension

Filtering by named queries has been added to the REST Data with Panache extension.

You can find more information about it in the REST Data with Panache guide.

OIDC FrontChannel logout

The OIDC extension adds support for OIDC FrontChannel logout.

Hibernate ORM - IN clause parameter padding enabled by default

Quarkus 2.15 adds the configuration property to the Hibernate ORM extension, and enables it by default.

It improves the caching of queries containing IN clauses.

CLI improvements

Two major improvements for the Quarkus CLI in 2.15:

  • Continuous testing is available in the Quarkus CLI with the quarkus test command.

  • Building and pushing images is as simple as quarkus image build / quarkus image push.

-XX:ArchiveClassesAtExit for AppCDS creation

When using Java 17+ to create AppCDS archives, Quarkus automatically enables the -XX:ArchiveClassesAtExit option.

Dev Services para Kubernetes

Dev Services is one of the Dev Experience features that make Quarkus unique. Quarkus 2.15 introduces Dev Services for Kubernetes so that you can easily test your applications using the Kubernetes Client extension.

Test framework for Google Cloud Functions

The Google Cloud Functions extensions now have a test framework utility in the form of the quarkus-test-google-cloud-functions artifact.

You can find more information about it in the Google Cloud Functions guide.
