MicroProfile 6.1 aligns with the Jakarta EE 10 Core Profile and introduces MicroProfile Telemetry, replacing MicroProfile OpenTracing.

MicroProfile 6.1 includes updates to all the major MicroProfile specifications.

The following specifications might include API incompatible changes for MicroProfile 6.1:

You must update your applications that use these specifications to the latest Jakarta EE 10 specifications.

You can update your applications to MicroProfile 6.1 by choosing one of the following methods:

Adding the MicroProfile 6.1 dependency to your project’s pom.xml file.
Using the JBoss EAP XP BOMs to import supported artifacts to the JBoss EAP XP dependency management of your project’s pom.xml file.

MicroProfile OpenTracing is not supported in JBoss EAP XP 5.0 and is replaced by OpenTelemetry tracing.

To replace MicroProfile OpenTracing with OpenTelemetry Tracing, follow these steps:

Replace the dependency org.eclipse.microprofile.opentracing:microprofile-opentracing-api with io.opentelemetry:opentelemetry-api and io.opentelemetry:opentelemetry-context.
Replace the usage of the org.eclipse.microprofile.opentracing Java package with the io.opentelemetry Java package. Such replacement might involve additional changes to classes and methods.

MicroProfile Metrics is not supported in JBoss EAP XP 5.0 and is replaced by Micrometer.

To replace MicroProfile Metrics with Micrometer, follow these steps:

Replace the dependency org.eclipse.microprofile.metrics:microprofile-metrics-api with io.micrometer:micrometer-core.
Replace the usage of the org.eclipse.microprofile.metric Java package with the io.micrometer Java package. Such replacement might involve additional changes to classes and methods.
