The below is before automated changelog management

2.3.0

Added

  • Spandex.current_context/1 and Spandex.Tracer.current_context/1 functions, which get a Spandex.SpanContext struct based on the current context.
  • Spandex.inject_context/3 and Spandex.Tracer.inject_context/2 functions, which inject a distributed tracing context into a list of HTTP headers.

Changed

  • The Spandex.Adapter behaviour now requires an inject_context/3 callback, which encodes a Spandex.SpanContext as HTTP headers for distributed tracing.

2.2.0

Added

  • The Spandex.Trace struct now includes priority and baggage fields, to support priority sampling of distributed traces and trace-level baggage, respectively. More details about these concepts can be found in the OpenTracing documentation. An updated version of the spandex_datadog library will enable support for this feature in terms of the Spandex.Adapter and Sender APIs.

Changed

  • It is no longer required that you specify the env option. If not specified, it will default to nil. This is useful, for example, for allowing the Datadog trace collector configured default to be used.
  • The Spandex.Adapter.distributed_context/2 callback now expects a SpanContext struct to be returned, rather than a Map.
  • Similarly, the Spandex.continue_trace function now expects a SpanContext struct rather than a separate trace_id and span_id.
  • The sender API now calls the send_trace function, passing in a Spandex.Trace struct, rather than passing a list of Spandex.Span structs. This means that you need to update the spandex_datadog to a compatible version.

Deprecated

  • Spandex.continue_trace/4 is deprecated in favor of Spandex.continue_trace/3
  • Similarly, Tracer.continue_trace/4 is deprecated in favor of Tracer.continue_trace/3
