Summary
In this release, Application Performance Monitoring (APM) adds W3C trace context propagation support. The new default propagation list is tracecontext,Datadog for injection and extraction. See the docs for more configuration details.
APM also re-introduces the collection of client ip address as an opt-in feature, even when ASM isn't configured. This can be enabled by setting DD_TRACE_CLIENT_IP_ENABLED.
Application Security Management (ASM) introduces IP blocking to Gin and Echo, along with a new public API to log security-related events.
The profiler now uses the faster delta profile implementation by default, first introduced in version 1.44.0. This significantly reduces the memory allocations from profile manipulation.
