This release deprecates the entire io.opentelemetry.instrumentation.api.tracer package in the instrumentation-api artifact, and the package will be removed in the next release.
The new Micrometer instrumentation will now capture metrics already defined in instrumented applications (e.g. some libraries have built-in micrometer metrics, like spring boot for example) and send them out through the agent metrics pipeline.
This release requires the use of OpenTelemetry Java SDK 1.10.0.
Note that all artifacts other than io.opentelemetry.javaagent:opentelemetry-javaagent have the -alpha suffix attached to their version number, reflecting that they are still alpha quality and will continue to have breaking changes. Please see the VERSIONING.md for more details.
