2.0.0

Connexion 2.0 supports version 3.0.x of the OpenAPI Specification!
As 2.0 is a major version bump, you can expect some breaking changes from Connexion 1.5.3.

• You can now use openapi 3 specifications
• Swagger UI is now optional, and can be installed with pip install connexion[swagger-ui]
• App and Api options must be provided through the "options" argument (old_style_options have been removed).
• You must specify a form content-type in 'consumes' in order to consume form data.
• The Operation interface has been formalized in the AbstractOperation class.
• The Operation class has been renamed to Swagger2Operation.
• Array parameter deserialization now follows the Swagger 2.0 spec more closely.
  In situations when a query parameter is passed multiple times, and the collectionFormat is either csv or pipes, the right-most value will be used.
  For example, ?q=1,2,3&q=4,5,6 will result in q = [4, 5, 6].
  The old behavior is available by setting the collectionFormat to multi, or by importing decorators.uri_parsing.AlwaysMultiURIParser and passing parser_class=AlwaysMultiURIParser to your Api.
• The spec validator library has changed from swagger-spec-validator to openapi-spec-validator.
• Errors that previously raised SwaggerValidationError now raise the InvalidSpecification exception.
  All spec validation errors should be wrapped with InvalidSpecification.
• Support for nullable/x-nullable, readOnly and writeOnly/x-writeOnly has been added to the standard json schema validator.
• Custom validators can now be specified on api level (instead of app level).
• Added support for basic authentication and apikey authentication
• If unsupported security requirements are defined or x-tokenInfoFunc/x-tokenInfoUrl is missing, connexion now denies requests instead of allowing access without security-check.
• Accessing connexion.request.user / flask.request.user is no longer supported, use connexion.context['user'] instead

1.5.3

• Fix error codes for bad Content-Types in body validator. (#629)
• Add validator kind to error logs extra in validators (#671)
• Improve metrics reporting (#672)
• Improve coroutine detection (#600)
• Add x-nullable support for body validators (#642)
