v1.46.0

Summary

• This release changes how header extraction and injection are configured. The DD_PROPAGATION_STYLE_INJECT and DD_PROPAGATION_STYLE_EXTRACT environment variables are now deprecated. Prefer the new environment variables DD_TRACE_PROPAGATION_STYLE_INJECT, DD_TRACE_PROPAGATION_STYLE_EXTRACT, and DD_TRACE_PROPAGATION_STYLE (which generally applies to both inject and extract).
  For example, the environment variables would take the following precedence:
  • DD_TRACE_PROPAGATION_STYLE_INJECT
  • DD_PROPAGATION_STYLE_INJECT (deprecated)
  • DD_TRACE_PROPAGATION_STYLE (applies to both inject and extract)
  • If none of the above, use default values

What's Changed

• tracer: replaces INJECT/EXTRACT environment variable names by @katiehockman in #1603

Full Changelog: v1.45.1...v1.46.0

v1.45.1

Fix the version number reported by dd-trace-go to avoid the release candidate label.

v1.45.0

Summary

Application Security Monitoring now becomes Application Security Management (ASM) with the release of IP blocking for HTTP and gRPC servers, which allows you to block attackers based on their IP addresses, managed from your denylist. You can request a private beta access to this feature here.

Changes

• General tag changes by @zhamza99 in #1562
• ddtrace/tracer/textmap: Added none as a supported propagator for trace context extraction and injection by @dianashevchenko in #1610

Fixes

Profiler

• Fix duration in (fast)delta profiles by @pmbauer in #1612

Full Changelog: v1.44.1...v1.45.0

v1.44.1

This patch release fixes an issue with Go modules version selection when dd-trace-go is updated using go get -u all, where an unstable indirect dependency was unexpectedly upgrading to an incompatible version and therefore leading to a compilation error.

Full Changelog: v1.44.0...v1.44.1

v1.44.0

Summary

This version notably brings:

• gofiber trace propagation: Users of the gofiber package will now have fully connected traces.
• The profiler adds a new, efficient profile delta computation algorithm, which eliminates almost all of the memory allocation caused by the profiler when delta profiles are enabled. This algorithm can be enabled with the DD_PROFILING_DELTA_METHOD=fastdelta environment variable. It will become the default in a future release.
• The profiler no longer adds an env tag to profiles unless one is explicitly configured, either through the DD_ENV environment variable or through the WithEnv option. This allows profiles to be tagged with the env value configured by the agent, if one is available, rather than getting the previous env:none default tag.
• Remotely enable Application Security Monitoring through Datadog's remote configuration (private beta access required).

A list of minor improvements and fixes can be found in the list below:

v1.43.1

Summary

The http.client_ip tag of HTTP request spans is no longer collected by Application Performance Monitoring (APM) and is now only reported by Application Security Monitoring (ASM), as part of its security monitoring metadata. If you are still interested in this feature without ASM, please file a feature request.

Fixes

• appsec: report http.client_ip only when appsec is enabled (#1523)

Full Changelog: v1.43.0...v1.43.1

v1.43.0

Summary

This version notably brings:

• Application Security Monitoring on linux/arm64 and darwin/arm64
• The profiler now captures its own CPU overhead. Previously, CPU profiling could be stopped before follow-on work processing the other profile types completed. There is now proper synchronization so this work is captured. Note that there may be a small (<1%) increase in CPU time on profiles. This is not new overhead, or a regression. It is just work that was already being done, now more accurately reflected.
• The new ddtrace.UseLogger function can be used to configure logging for both the tracer and profiler.

A couple of improvements and fixes can also be found in the list of changes below.

v1.42.0

Summary

This release has several exciting features:

• Adds support for Go 1.19. Please note that this means Go 1.17 has maintenance support, and Go 1.16 has legacy support. See our version support policy for more details.
• Introduces support for propagation of trace context via SQL commenting. This experimental feature injects trace context information via sql comments in the sqlcommenter format.
