Summary

In this release, Application Performance Monitoring (APM) will now correctly honor the trace context propagation style precedence, where previously W3C tracecontext style would always take precedence even when a user specifies it later in the chain. This is a bug fix to align with expected behavior, but could potentially be a breaking change for customers relying on W3C trace context propagation.

Other APM changes include deprecation of the old Gorm libraries (gopkg.in/jinzhu/gorm.v1 and jinzhu/gorm), and fixes for net/http contrib to now honor WithHeaderTags in WrapHandler, the http.route tag to be correctly collected in all relevant libraries.
