Version 1.27.0

This release targets the OpenTelemetry SDK 1.27.0.

Note that many artifacts 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

• Jersey 3.0 instrumentation suppression keys have changed from jaxrs-2.0 to jaxrs-3.0, and from jersey-2.0 to jersey-3.0 (#8486)
• The opentelemetry-runtime-metrics artifact has been renamed and split into opentelemetry-runtime-telemetry-java8 and opentelemetry-runtime-telemetry-java17 (#8165, #8715)
• InetSocketAddressNetServerAttributesGetter and InetSocketAddressNetClientAttributesGetter have been deprecated (#8341, #8591)
• The new HTTP and network semantic conventions can be opted into using either the system property otel.semconv-stability.opt-in or the environment variable OTEL_SEMCONV_STABILITY_OPT_IN, which support two values:
  • http - emit the new, stable HTTP and networking attributes, and stop emitting the old experimental HTTP and networking attributes that the instrumentation emitted previously.
  • http/dup - emit both the old and the stable HTTP and networking attributes, allowing for a more seamless transition.
  • The default behavior (in the absence of one of these values) is to continue emitting the same HTTP and network semantic conventions that were emitted in 1.26.0.
  • Note: this option will be removed later this year after the new HTTP and network semantic conventions are marked stable, at which time the Java instrumentation version will be bumped from 1.x to 2.0, and the old HTTP and network semantic conventions will no longer be supported.
