opentelemetry-java-instrumentation

This release targets the OpenTelemetry SDK 1.14.0.

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.

• Micrometer library instrumentation has been removed as it has been moved to the core repo and is now published under io.opentelemetry:opentelemetry-micrometer1-shim
• The rxjava javaagent instrumentation names for suppression have changed to rxjava
• AgentListener#beforeAgent() has been deprecated, as it is not expect to be needed by extensions authors
• ConfigPropertySource has been deprecated in favor of ConfigCustomizer

  package in the instrumentation-api artifact, and the package was removed in this release.

  smaller now and there is no longer a significant size difference between the -slim and default
  artifacts.

  opentelemetry-aws-lambda-core-1.0 and opentelemetry-aws-lambda-events-2.2.

This is a patch release on the previous 1.10.0 release, fixing the issues below. If you are not affected by any of these, you do not need to update.

🛠️ Bug fixes

• Regression in project reactor context propagation instrumentation (#5188)
• Recover from duplicate class definition errors (#5185)
• StringIndexOutOfBoundsException in AWS SDK v1 when using request object subclass (#5231)
• Update to OTel SDK 1.10.1 (#5218)

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.

This is a patch release on the previous 1.7.1 release, fixing the issues below. If you are not affected by these, you do not need to update.

🛠️ Bug fixes

• HTTP exporter does not properly close connections (#4581)
• IndexOutOfBounds in Apache HTTP client instrumentation (#4575)
• Exception in certain logging messages (#4540)
• NPE in Jetty instrumentation (#4527)

Due to an issue in the publishing infrastructure, a bad release was published as 1.8.0. Do not use it.

This is a patch release on the previous 1.7.0 release, fixing the three issues below. If you are not affected by these, you do not need to update.

🛠️ Bug fixes

• Java agent 1.7.0 fails with prometheus exporter (#4460)
• Android regression in okhttp instrumentation in 1.7.0 (#4452)
• Remove unshaded javax.annotation classes from bootstrap class loader (#4454)

Note: with this release, the -all artifact has been removed and the default artifact (with no classifier) is now the go-to artifact that contains the exporters. If you want an artifact with no exporters, there is a new -slim artifact that is published to maven central. The -all artifact is still attached to this release below (it has the same content as the default artifact), but will no longer be attached to the releases starting from v1.8.0.

This release requires the use of OpenTelemetry Java SDK 1.7.0.

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.

📈 Enhancements

• Change the default javaagent artifact to have exporters, introduce new -slim artifact,
  and deprecate the -all artifact (#4106)
• Support jlinked images without jdk.unsupported module (#4154, #4124)
• Added experimental option to suppress messaging receive spans (#4187, #4204)
• Refine 404 handling in Restlet instrumentation (#4206)
• Remove dynamo db.name attribute (#4208)
