We understand that OAS 3.x being latest to Swagger 2.0 specification.
OAS 3.0 lists following changes
1.Structural improvements
2.Request Parameters
3.Protocol and Payload
4.Documentation
5.Security
& few other outlined information in terms of differences like
OAS 3.0 offers support for describing callbacks, which can be used to define asynchronous APIs or Webhooks, Extended JSON Schema support & Some security definition changes
But from a business Use case prospective do we opt for OAS 3.x ? we see more from structural changes from Swagger 2.0 to OAS3.X.
Like one of case will be more readability/interactivity to documentation with respect to Example value for response is a valid Business case.
