0.33.1-rc1

Main Changes since 0.33.0

• Disabled OpenMetrics exemplars within Prometheus to fix 1023

Full list of addressed issues can be found under the 0.33.1 milestone.

0.33.0

Main Changes since 0.32.0

• Dependency updates (Kafka 4.1.0, Vert.x 5.0.4, Netty 4.2.5.Final, JMX Prometheus collector 1.3.0, OAuth 0.17.0).
• Updated OpenAPI specification to 3.1.0.
• Added validation_errors field within the JSON object, as part of the Error OpenAPI component, returned by the bridge when there is a schema validation error.
  Such field is omitted when the error is not schema validation related.
• Fixed multithreaded access to the KafkaConsumer instance within a sink endpoint.

Changes, deprecations and removals

• The OpenAPI specification was bumped to 3.1.0 in order to deal with the new JSON Schema support for null type.
  It was not possible to deprecate the 3.0.0 first due to the Vert.x OpenAPI component refactoring within Vert.x 5.
• Removed the following OpenTelemetry span attributes that were deprecated since 0.28.0 release.
  1. http.method is being replaced with http.request.method
  2. http.url is being replaced with url.scheme, url.path & url.query
  3. messaging.destination is being replaced with messaging.destination.name
  4. http.status_code is being replaced with http.response.status_code
  5. messaging.destination.kind=topic without any replacement
