# Changelog
## Version 1.11.1 - 2022-02-21
### 🛠️ Bug fixes
- Regression in loading the prometheus exporter
([#5408](https://github.com/open-telemetry/opentelemetry-java-instrumentation/pull/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`.
