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.

    • A new SPI AgentExtension was introduced: it replaces ByteBuddyAgentCustomizer;
    • InstrumentationModule#getOrder() was renamed to order();
    • InstrumentationModule#additionalHelperClassNames() has been removed; use isHelperClass(String) instead if you use the muzzle compile plugin. If you're not using muzzle, you can override getMuzzleHelperClassNames() directly instead;
    • InstrumentationModule#getAllHelperClassNames() has been removed; you can call getMuzzleHelperClassNames() to retrieve all helper class names instead.
