Hibernate Reactive 1.0.0.Final

Among other fixes and improvements, in this release all methods which "open a session" have been made reactive.

Please, refer to the getting started documentation to find out more about the release.

Kafka Streams DevUI

The Quarkus DevUI now includes support for the topology visualizer, which looks like this example.

Continuous testing for multi module projects

Continuous testing will now run tests from all the project modules, with the option to configure the old behaviour. The new config options include:

  • quarkus.test.only-test-application-module (default value is false) - if false then tests from all dependency modules will be run as well;

  • quarkus.test.include-module-pattern - a regular expression matched against the module groupId:artifactId, tests from the matched modules will be included in the continuous testing;

  • quarkus.test.exclude-module-pattern (ignored if include-module-pattern has been set) - a regular expression and is matched against the module groupId:artifactId, tests from the matched modules will be excluded from the continuous testing.

AWT image resize via new AWT extension

A new io.quarkus:quarkus-awt extension for AWT and Java2D usage was added to enable various AWT use-cases, such as image resizing.
