Release 1.25.0

[pellared]

This release adds experimental logs support. Set OTEL_LOGS_EXPORTER=otlp to enable logs support. However, take notice that, as of now, the OpenTelemetry Go Logs API is not stable.

The release requires at least Go 1.23.

This release upgrades OpenTelemetry Go to v1.35.0/v0.57.0/v0.11.0 and OpenTelemetry Go Contrib to v1.35.0/v0.60.0/v0.29.0/v0.15.0/v0.10.0/v0.8.0/v0.7.0.

Added

• Add logs support and OTEL_LOGS_EXPORTER environment variable.
  OTEL_LOGS_EXPORTER accepts:

  • none - logs disabled,
  • otlp - OTLP gRPC exporter.

  Currently, OTEL_LOGS_EXPORTER defaults to none as the OpenTelemetry Go Logs API and SDK are not stable yet. Set OTEL_LOGS_EXPORTER=otlp to enable logs support. (distro: Add opt-in logs support #3673)

Removed

• Drop support for Go 1.22. (Drop support for Go 1.22 #3721)
