[0.22.0](https://github.com/aws/aws-pdk/compare/v0.21.6...v0.22.0) (2023-09-08)
⚠ BREAKING CHANGES
* **pipeline:** Removed RequestArrayParameters from input and type signature of
handlers/interceptors. number/bool/date request parameters will be coerced to their type defined in
the model. useIntegerType: true is specified by default for smithy to openapi conversion as this is
recommended and more intuitive behaviour than the default (where integers are still represented as
doubles).
* **pipeline:** Removed RequestArrayParameters from handler inputs and folded them into
RequestParameters. Renamed CorsInterceptor to ResponseHeadersInterceptor. Validated to ensure only
primitives (or arrays of primitives) are used in request paramters (query/path/headers).
RequestParameters coerce string values into their appropriate types for the handler wrappers to
consume, and will respond with a 400 if request parameters are of the wrong type.
* feat(type-safe-api): coerce python request parameters into declared types
Removes request_array_parameters and folds all request parameters into input.request_parameters.
cors_interceptor.py is now response_headers.py for the cors interceptor.
