• The endpoint parameter is now referenceable, and can be stored as a secret in a vault.#11220

Release date 2023/05/19

Feature

• These plugins now convert traceid in HTTP response headers to hex format.#10534

• Spans are now correctly correlated in downstream Datadog traces.10531

• Added the header_type field. Previously, the header_type was hardcoded to preserve. Now it can be set to one of the following values: preserve, ignore, b3, b3-single,w3c, jaeger, or ot.#10620

• Added the new span attribute http.client_ip to capture the client IP when behind a proxy.#10723

• Added the http_response_header_for_traceid configuration parameter. Setting a string value in this field sets a corresponding header in the response.#10379

Bugfix

• Fixed an issue where reconfiguring the plugin didn’t take effect.

• Fixed an issue that caused spans to be propagated incorrectly resulting in the wrong hierarchy being rendered on tracing backends.#10663

Release date 2023/02/28

Feature

• This plugin can now be scoped to individual services, routes, and consumers.#10096

Bugfix

• Fixed an issue in these plugins’ batch queue processing, where metrics would be published multiple times. This caused a memory leak, where memory usage would grow without limit.#10052 #10044

• Fixed non-compliances to specification:

  • For http.uri in spans, the field is now the full HTTP URI. #10036
  • http.status_code is now present on spans for requests that have a status code. #10160
  • http.flavor is now a string value, not a double. #10160

• For http.uri in spans, the field is now the full HTTP URI. #10036

• http.status_code is now present on spans for requests that have a status code. #10160

• http.flavor is now a string value, not a double. #10160

• Fixed an issue with getting the traces of other formats, where the trace ID reported and propagated could be of incorrect length. This caused traces originating from Kong Gateway to incorrectly connect with the target service, causing Kong Gateway and the target service to submit separate traces.#10332
