Release v1.25.0

This is a regular cadence release following upstream OpenTelemetry Java Instrumentation.

🗒 General

• OpenTelemetry Java SDK has been updated to version 1.27.0.

• OpenTelemetry Instrumentation for Java has been updated to version 1.27.0.

• Micrometer dependency has been updated to version 1.11.1.

• Jackson dependencies have been updated to 2.15.2.

• This release includes a preview of the new HTTP and network semantic conventions. It can be activated by setting the system property otel.semconv-stability.opt-in (or the environment variable OTEL_SEMCONV_STABILITY_OPT_IN) to one of:

  • http - emit the new stable HTTP and networking attributes, without emitting the old unstable attributes;
  • http/dup - emit both the new stable attributes and old unstable attributes;
  • If no value is specified, the default behavior is to emit the old semantic conventions.

  The javaagent 2.0 release planned for October will only emit the new stable semantic conventions. This setting can be used to prepare for transition to the 2.0 version.
