opentelemetry-java-instrumentation/CHANGELOG.md

Changelog

Version 1.11.1 - 2022-02-21

🛠️ Bug fixes

• Regression in loading the prometheus exporter (#5408)

Version 1.11.0 - 2022-02-11

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.
