Designer Series: What's New in SwaggerHub (1st November 2023)

Just watched the above webinar and was interested in the differences between OpenAPI Specification 3.0.x and 3.1.x.

The presenter had 2 NickPetStore yaml files that showed the difference between the versions.

Any chance of sharing those specifications?

Also the presentation referred to a related blog - is there a link to that?

Thanks
