Versionless stand-alone MicroProfile Liberty features

In 24.0.0.8, Open Liberty introduced versionless MicroProfile features. Versionless features allow you to easily use Liberty features without needing to know what feature version to use. The initial release of versionless features did not include the stand-alone MicroProfile technologies that are not part of the MicroProfile releases, but can work with the other MicroProfile features. An example of such a feature is mpContextPropagation-1.3.

In 24.0.0.10, Open Liberty adds versionless features for stand-alone MicroProfile features. The following versionless features were added:

  • mpContextPropagation

  • mpGraphQL

  • mpReactiveMessaging

  • mpReactiveStreams

The following server.xml configuration file uses the MicroProfile platform microProfile-6.1 with the new versionless stand-alone features:

<featureManager>
    <platform>microProfile-6.1</platform>
    <feature>mpContextPropagation</feature>
    <feature>mpGraphQL</feature>
    <feature>mpReactiveMessaging</feature>
    <feature>mpReactiveStreams</feature>
</featureManager>
