Summary
Application Performance Monitoring (APM) ships various new features and bug fixes such as support for elastic/go-elasticsearch/v8 and for dimfeld/httptreemux/v5. Additional features include new tags for mssql in database/sql, and new tags for mgo. This release also includes a bug fix to how baggage is propagated when using W3C trace context injection/extraction.
Application Security Monitoring (ASM) adds support for multiple IP-related HTTP headers as well as fixing HTTP status code reporting for blocked users in labstack/echo.
Telemetry information is now enabled by default, to disable set DD_INSTRUMENTATION_TELEMETRY_ENABLED to false. Additional information can be found here.
Breaking Changes
- Fix returned OS name on Linux by @albertvaka in #1791
This change fixes our lookup of OS name in linux systems that is used for our startup logging. If you are parsing those startup logs and relying on the value of os_name you may experience a breaking change as the value may shift from "Linux (Unknown Distribution)" to the now correctly identified OS name.
The PprofDiff function is deprecated and will be removed from the profiler package in the next release.
