OpenAPI automations have been added to the documentation, allowing for seamless autogeneration of API Reference docs and removing manual labor required to reflect changes in production. The new functionality can be achieved by adding an openapi field to objects in tabs or anchors arrays in the mint.json file, or by using OpenAPI Specs hosted at a URL. The feature is now available for developers to try out, and instructions on how to update their CLI and add the code to their mint.json file are provided.
