July 11, 2025

Bi-Directional Contract Testing improvements
- We added a new comparison engine that delivers up to 100x faster performance than the previous engine.
- We added support for configurable behavior.
Stub server updates
- Stub servers now support the Pact specification up to version 4.
- We included additional configuration options.
OpenTelemetry support
- We added native OpenTelemetry (OTel) instrumentation for enhanced observability in on-premise environments. This allows you to monitor API performance, troubleshoot issues faster, and integrate PactFlow On-Premises into existing observability stacks.
- See the OpenTelemetry guide for setup instructions and details.
HAL updates
- Now you can delete an integration in the HAL relations and expose it in the HAL Explorer.

We improved support for URI-encoded paths in BDC for OpenAPI.
We removed Byte Order Mark (BOM) from providers contracts, if it was there.
We fixed a recurring 401 error triggered by the auth_ext_script custom extension.
