v2.2.3

What's Changed

This patch release fixes a significant bug that caused dropped spans due to local sampling rules overriding the sampling decision already present in inbound distributed trace context.

Important

Depending on your sampling rules, and especially if you have trace sampling rules,, you may notice an increase in ingested spans. This increase is expected and the consequence of not applying trace sampling rules when there is a head sampling decision. If the ingested volume is problematic, reduce it using APM Ingestion Controls. For any questions or issues, please contact Datadog Support.

• fix(ddtrace/tracer): keep correct trace+span sampling with propagated sampling decision by @darccio in #3856
• chore: update the remoteconfig dependency by @andreimatei in #3883

Summary

Application Performance Monitoring (APM)

Client-Side Stats Computation

Client-Side Stats computation is now enabled by default. This feature allows the Go tracer to compute aggregated span statistics locally before sending them to the Datadog Agent, resulting in reduced network traffic and improved performance.

What this means: Instead of sending all raw span data to the Agent, the tracer now sends pre-computed statistics, reducing bandwidth usage while maintaining full observability.

To disable, if needed: Set the environment variable DD_TRACE_STATS_COMPUTATION_ENABLED=false or use tracer.WithStatsComputation(false) when starting the tracer programmatically.

File-based Configurations

Introduced support for configuring SDK products via a file on the underlying Linux system. #3438 Documentation

Baggage improvements

Fixed a distributed tracing bug in the baggage propagator. Also refactored baggage injection and extraction logic for improved performance and readability. #3439 #3597

Application Security Management (ASM)

contrib envoyproxy/go-control-plane:

• API Security
  • Proxy sampler has been implemented for schema generation
  • Support of Json body analysis of requests and responses (using simdjson-go or fallbacking on json-iterator/go if not available)
• Appsec
  • Support of Envoy observability_mode for async and non-blocking requests analysis

v1.73.2

What's Changed

Note

This is a patch release of the last v1 version before the v1 transitional release v1.74.0 planned for May/June 2025. The Go tracer v1 transitional version is essentially a wrapper that preserves the API from v1 but uses v2 under the hood.

The transitional version can co-exist with v2 in the same service, which enables you to migrate services gradually. Using the v1 transitional version - starting at v1.74.0 - doesn’t require any code changes, but it also won’t support any new features of the new v2 tracer.

The v1 transitional version is planned for release in late May/early June 2025 as v1.74.0.
