Version 1.11.0

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.

Migration notes

• The previous release (1.10.0) deprecated the entire io.opentelemetry.instrumentation.api.tracer
  package in the instrumentation-api artifact, and the package was removed in this release.
• The javaagent -slim artifact has been dropped in this release, because the exporters are much
  smaller now and there is no longer a significant size difference between the -slim and default
  artifacts.
• The opentelemetry-aws-lambda-1.0 has been split into two artifacts
  opentelemetry-aws-lambda-core-1.0 and opentelemetry-aws-lambda-events-2.2.
