The long awaited OpenAPI 3.0 specification has officially been released! OpenAPI 3.0 is the next evolution of the Swagger specification. With the release of 3.0, the specification — which was donated to the OpenAPI Initiative by SmartBear Software in 2015 — will not only be formally getting a new name, but will also be adding powerful new features for your API development.
What does OAS 3.0 means for API teams?
With the release of OAS 3.0, the API economy now has a common standard for teams to define their RESTful APIs. For teams that are already using the Swagger 2.0 specification, 3.0 adds several significant improvements, including: support for describing callbacks, links to express relationships between operations, enhanced examples, and a simplified structure for better reusability. For teams that are just starting their journey with defining RESTful APIs, the release of OAS 3.0 presents an opportunity to get started with a specification that has become the chosen standard for organizations across industries, around the world. Ole Lensmar, CTO, SmartBear Software and Chair of the OAI Board, explains the significance of the 3.0 release: "The release of this third-generation format is a significant milestone for our community. The updates made are entirely user and usage driven and that plays a huge role in the success of the specification. One of the most powerful things about this release is its ability to drive the full API lifecycle."
