🔨 Breaking Changes

• Dropped Prettier formatting and all formatting options. Now, simply format at your discretion (or not at all!)
• Dropped support for Swagger 2.0
• Dropped Node 14 support (it still works for now, but Node 14 bugs won’t be fixed if any arise)
• --version was changed to return the version of this library (also by dropping Swagger 2.0 support the old usage was no longer needed)
• Dropped --raw-schema. Your entry schema MUST be valid and complete (however, your $refs to subschemas may be partials).
• Dropped --make-paths-enum because it was incompatible with --path-params-as-types
• Dropped the CLI aliases -it and -ap (specify the full --immutable-types or --additional-properties flag)
• Empty content: {} now returns never. Dropped the --content-never flag as this is now the default behavior.
• Renamed and upgraded the Node API’s formatter() function to transform() and postTransform(). It’s an overall improvement on the original concept with even more power than before.
