Start by listing the differences required to forms based on spec version 3.0

[JeHugawa]

Differences with swagger specification version 2.0 and OpenAPI specification version 3.0.

• URL structure. Swagger 2 lets you define a host and a baseURL, wherein OpenAPI 3 you define them both in URL. You can also have description for each url and multiple URLs for different paths in openAPI3. They're specified under "servers" in OpenAPI 3.

• Components Swagger 2 had a concept of definitions, but OpenAPI 3 replaces them with components.

• Request Format In swagger 2, they were subset of parameters, wherein OpenAPI 3 body and formdata are merged into one requestbody.

• responses You don't have to define each response seperately anymore. Also callbacks let you define webhooks.

• link object OpenAPI 3 adds linking.

• chances to security Security has been renamed, OAuth2 flow names have been updated, you can have multiple flows, and there’s support for OpenID Connect. Basic type is now htpp and security has now "scheme" and "bearerformat".
