Summary

With this release, the Go tracer now starts reporting a set of security monitoring tags for each server request without the need to enable ASM. Currently, the collected tags are http.client_ip, http.useragent, http.status_code and http.method, and more will come with future releases. More information about this can be found in the Datadog documentation.
Other additions include a new integration for the logrus logging package, and overriding the sampling decision of a trace
in downstream services is now possible. Additionally, a new tag aws.request_id was added to spans for the aws-sdk-go
integration. On top of this the tracer has a new option, WithUniversalVersion, which removes the limitation of having the service name
match the name defined when starting the tracer for version tracking.
Some more fixes and improvements were made which you can find in the changelog below.
