MicroProfile Telemetry 2.1

MicroProfile Telemetry 2.1 (mpTelemetry-2.1) provides developers with updated Open Telemetry technology. The feature now uses OpenTelemetry v1.48.0, which is updated from v1.39.0. The previously exposed experimental APIs are now stable.

<featureManager>
   <feature>mpTelemetry-2.1</feature>
</featureManager>

To use the OpenTelemetry API, it is no longer required to add the apiTypeVisibility="+third-party" attribute to the classloader element of the server.xml. This also means that it is now possible to deploy an application that uses the OpenTelemetry API by dropping it into the dropins directory.

MicroProfile OpenAPI 4.1

OpenAPI is a standardized way of documenting REST APIs in a JSON or YAML format. MicroProfile OpenAPI helps to generate and serve OpenAPI documentation for REST applications that are built by using JAX-RS or Jakarta restfulWS. This can be useful for developers to test out the API during development, or for people who use API in production.

To use the new MicroProfile OpenAPI 4.1 (mpOpenAPI-4.1) feature, first add the feature to your server.xml:

<featureManager>
    <feature>mpOpenAPI-4.1</feature>
</featureManager>

Next, deploy any REST application. Then, in a web browser, go to /openapi on the Liberty server to view the YAML OpenAPI document, or go to /openapi/ui for a user interface to browse through the documentation. To enhance the documentation, use annotations in code to add additional information, like textual descriptions, to each method. The annotations are available as a maven dependency:

<dependency>
    <groupId>org.eclipse.microprofile.openapi</groupId>
    <artifactId>microprofile-openapi-api</artifactId>
    <version>4.1</version>
    <scope>provided</scope>
</dependency>

MicroProfile OpenAPI 4.1 is a small release which adds:
