✨ New Features

WSDL Contract Import

Projects can now be created directly from a WSDL specification. The platform parses the WSDL and referenced XSD files, extracts all methods with their enrichments, and generates a contract that seamlessly replaces an existing service — clients continue calling the same URL and method interface without changes.

OPA-Based JWT Validation Mode

A new External OPA Validation engine option lets services delegate JWT validation and authorization decisions to an external Open Policy Agent. When enabled, OpenLegacy acts as a Policy Enforcement Point (PEP) and forwards every request's token and context to OPA for an allow/deny decision — no built-in signature, issuer, or audience checks are performed. Supports configurable fail-closed (default) and fail-open modes.

🔧 Improvements

Drag & Reorder Contract Fields

Fields in the Input/Output contract model view can now be reordered via drag-and-drop, giving users full control over field positioning without resorting to export/import workarounds.

Import Model – Override or Concatenate

The model import dialog now asks whether to override or add to existing fields in the Input, Output, and Expression steps. This is especially useful when the same fields appear across multiple steps.

Copy from Asset with REDEFINE Selection

When copying a model from an asset or uploading a copybook that contains COBOL REDEFINE statements, a new review step displays a carousel of available REDEFINE options. Users can lock their preferred structure — or pick a saved variant — before generating the model.
