Connexion 3 is now in Alpha 🎉
* Connexion can now be used as middleware to supercharge any ASGI or WSGI compatible framework.
* Aiohttp support has been dropped in favor of an ASGI compatible ``AsyncApp`` built on top of Starlette.
* Connexion functionality is now pluggable by adding or removing middleware.
* Validation is now pluggable by content type, solving longstanding issues regarding endpoints with
multiple content types and providing a pluggable interface.
Breaking changes
- Aiohttp support was dropped, use ``connexion.AsyncApp`` instead
- The ``options`` argument has been renamed to ``swagger_ui_options``
- The ``uri_parser_class`` is now passed to the ``App`` or its ``add_api()`` method directly
instead of via the ``options`` argument.
- The ``jsonifier`` is now passed to the ``App`` or its ``add_api()`` method instead of setting it
as an attribute on the Api.
- Drop Flask 1.X support and support Flask 2.X async routes
- Drop Python 3.6 (and add Python 3.10) support
- ``connexion.request`` is now a Starlette ``Request`` instead of a Flask ``Request``
- Route priority changed. The most specific route should now be defined first in the specification.
- We no longer guess a content type for response serialization if multiple are defined in the spec.
We do take into account returned headers.
- Don't return 400 when read-only property is received
- Content type is now validated for requests and responses if defined in the spec
- The deprecated positions for ``x-body-name`` are no longer supported
- The parameter ``pass_context_arg_name`` has been removed. Context is now available as global
request-level context, or can be passed in by defining a ``context_`` parameter in your view function.
- The ``MethodViewResolver`` has been renamed to ``MethodResolver``, and a new ``MethodViewResolver``
has been added to work with Flask's ``MethodView`` specifically.
- Built-in support for uWSGI has been removed. You can re-add this functionality using a custom middleware.
