Release v3.4.0

New Features

• Attribute http.statusCode has been added to external span events
  representing the status code on an http response. This attribute will be
  included when added to an ExternalSegment in one of these three ways:

  1. Using
     NewRoundTripper
     with your http.Client
  2. Including the http.Response as a field on your
     ExternalSegment
  3. Using the new
     ExternalSegment.SetStatusCode
     API to set the status code directly

  To exclude the http.statusCode attribute from span events, update your
  agent configuration like so, where cfg is your newrelic.Config object.

  cfg.SpanEvents.Attributes.Exclude = append(cfg.SpanEvents.Attributes.Exclude, newrelic.SpanAttributeHTTPStatusCode)

• Error attributes error.class and error.message are now included on the
  span event in which the error was noticed, or on the root span if an error
  occurs in a transaction with no segments (no chid spans). Only the most recent error
  information is added to the attributes; prior errors on the same span are
  overwritten.

  To exclude the error.class and/or error.message attributes from span events, update your
  agent configuration like so, where cfg is your newrelic.Config object.

  cfg.SpanEvents.Attributes.Exclude = append(cfg.SpanEvents.Attributes.Exclude, newrelic.newrelic.SpanAttributeErrorClass, newrelic.SpanAttributeErrorMessage)

Changes

• Use
  Context.FullPath()
  for transaction names when using Gin version 1.5.0 or greater. Gin
  transactions were formerly named after the
  Context.HandlerName(),
  which uses reflection. This change improves transaction naming and reduces
  overhead. Please note that because your transaction names will change, you
  may have to update any related dashboards and alerts to match the new name.

  // Transactions previously named
  "GET main.handleGetUsers"
  // will be change to something like this match the full path
  "GET /user/:id"
