MicroProfile Config

Injection points targeting beans annotated with org.eclipse.microprofile.config.inject.ConfigProperties, require to be annotated with the org.eclipse.microprofile.config.inject.ConfigProperties qualifier as stated in the MicroProfile specification. Previous Quarkus versions were only requiring a single @Inject.

Hibernate Reactive API changes

This version of Quarkus updated to Hibernate Reactive 1.0.0.CR10, in which a frequently used API changed signature;

to open a new Mutiny.Session from a Mutiny.SessionFactory you now have:

  • Uni<Session> openSession();
  • Uni<Session> openSession(String tenantId);
  • Uni<StatelessSession> openStatelessSession();
  • Uni<StatelessSession> openStatelessSession(String tenantId);

N.B. the difference: they no longer return a Mutiny.Session directly but a Uni of such object.

We considered giving these a new name, and deprecate the existing name, but since it's an experimental component and we really like this name we decided breaking the API was the better choice, for the long term benefits.

A similar change was applied to the Stage.SessionFactory: all methods opening a Stage.Session are now returning a CompletionStage<Session>.

gRPC Decoupled from HTTP

In previous versions of Quarkus adding the gRPC extension would also add the quarkus-vertx-http extension that would open a HTTP socket on port 8080 (as well as gRPC opening a port on 9000). This is no longer the case so if you wish to also serve content on port 8080 then you will need to install a HTTP extension such as quarkus-vertx-http or quarkus-resteasy-reactive.
