OptiFlow OpenAPI Update Analysis (v1.36 → v1.38)

I compared the two OpenAPI specs you provided (optiflow-1.36-openapi.json vs optiflow-1.38-openapi.json) and here’s what changed.

1) Endpoints / Paths

No new or removed endpoints.
All paths remain unchanged between 1.36 and 1.38.

So this update is mainly about new response structures / schema extensions, not API routes.

2) New Schemas (Classes) introduced in 1.38

Version 1.38 adds six new component schemas:

• AssignedResource
• AssignedResourceCosts
• LegLoad
• ResultCosts
• RouteCosts
• RouteDurations

Interpretation:
This introduces a more structured cost + duration reporting layer, plus resource assignments and leg-level load breakdowns.

3) Existing Schemas extended (new properties)

Several existing schemas gained new properties in 1.38.

Metrics (extended)

New fields:

• numberOfScheduledOrders
• costs

Meaning: metrics now not only report distances/durations/etc., but also how many orders were actually scheduled, plus a structured cost object (ResultCosts).

RouteMetrics (extended)

New fields:

• numberOfOrders
• durations
• costs

Meaning: route-level metrics now become more granular by including:

• order count per route
• a structured duration breakdown (RouteDurations)
• structured cost breakdown (RouteCosts)

Leg (extended)

New field:

• loads

Meaning: each leg can now include load data, using the new schema LegLoad.

This is useful if you want leg-by-leg capacity utilization instead of only route-level totals.

OptimizationResult (extended)

New field:

resources

Meaning: the optimization result can now include resource assignment information, likely represented via the new schema AssignedResource.

Summary (quick forum-style)
New Schemas

• AssignedResource
• AssignedResourceCosts
• LegLoad
• ResultCosts
• RouteCosts
• RouteDurations

New Properties in Existing Schemas

• Metrics: numberOfScheduledOrders, costs
• RouteMetrics: numberOfOrders, durations, costs
• Leg: loads
• OptimizationResult: resources

No path/endpoint changes

No routes were added or removed.

Client Impact / Compatibility Notes

This is non-breaking in typical JSON parsing scenarios, but:

If your client / DTO model is strict (e.g., schema validation, strict deserialization), you may need to update to accept:

• OptimizationResult.resources
• Leg.loads
• new nested cost/duration structures in Metrics and RouteMetrics
