Since 2.5.0, some REST API endpoints did not always mark required path and query parameters as such in the OpenAPI specification. This affected only a subset of endpoints. Tools consuming the spec, such as Swagger UI, API clients, or SDK generators, could therefore treat mandatory parameters as optional for those endpoints.
