Full Changelog: DataDog/dd-trace-go@v2.10.0...v2.10.1

v2.10.0

Summary

This release introduces the new Efficient Trace Protocol (ETP; v1.0) by default. If you want to opt-out and continue using the previous trace protocol, you can set DD_TRACE_AGENT_PROTOCOL_VERSION=0.4. ETP introduces significant improvements on performance and payload size in the wire.

There are other improvements regarding allocations and CPU usage in our tracer's hot paths, including an experimental span pool (available as tracer option and environment variable DD_TRACER_EXPERIMENTAL_SPAN_POOL_ENABLED).

New contribs:

• labstack/echo v5
• aerospike/aerospike-client-go v7

[datadog-prod-us1-6]

The update sets the core tracer to v2.10.1. Orchestrion still requires v2.9.0, so the Test Optimization build stops before test compilation.

[datadog-prod-us1-6]

Keep the Orchestrion tracer version aligned

The documented Test Optimization build cannot compile the Go example.

Assertion details

• Input: Run the Go example with --config=test-optimization after this dependency update.
• Expected: The core tracer, the two contrib modules, and the Orchestrion configuration must use the same version.
• Actual: The builder compares the configured v2.9.0 version with the resolved v2.10.1 version. It reports a version mismatch before compilation.
