OpenAPI does what Swagger don’t
Blog post from Postman
At the API Specifications Conference, Arnaud Lauret, Postman's OpenAPI Technical Lead, advocated for upgrading from Swagger 2 to OpenAPI 3, emphasizing that OpenAPI 3 is a newer iteration of the same specification. Lauret highlighted several enhancements in OpenAPI 3, including improved hosting and security definitions, flexible data serialization, and support for callbacks and webhooks. He acknowledged the challenges in transitioning, such as tool compatibility, and suggested using OpenAPI 3 as the primary reference while converting back to Swagger 2 when necessary during migration. Lauret stressed the importance of tool support for new specification versions and encouraged collaboration among software vendors to streamline adoption. With comprehensive support, developers can leverage new features and innovate more effectively, making the transition from Swagger 2 to OpenAPI 3 both necessary and beneficial.
