Release Notes

DataDog/nginx-datadog (DataDog/nginx-datadog)

v1.16.1

Compare Source

This release adds stable session identifier telemetry headers to improve observability for forking Nginx workers, and migrates RUM snippet creation to read its configuration from the agent's stable config file. It also fixes baggage extraction limits.

What's Changed

Functional Changes

• Stable session identifier telemetry headers. All telemetry requests now include DD-Session-ID and, in child processes, DD-Root-Session-ID. #​345
• RUM: snippet creation reads from stable config. RUM configuration is now sourced from the agent's application_monitoring.yaml stable config file. #​331
• Update underlying Datadog APM C++ Tracer to v2.1.0. #​366
• Remove support of Nginx 1.24.0 (which reached end of life on May 1st 2025). #​366

Bug Fix

• Baggage limits enforced on extraction. Size and count limits previously applied only on injection now also bound incoming baggage, preventing oversized propagation headers. #​362
