# 2.0.0

Major version update following from API change in `OpenApiSpex.cast` and `OpenApiSpex.validate`.
When casting/validating all parameters against an `OpenApiSpex.Operation`, the complete `Plug.Conn` struct must now be passed, where the combined params map was previously accepted.
This allows `OpenApiSpex.cast` / `OpenApiSpex.validate` to check that the parameters are being supplied in the expected location (query, path, body, header, cookie).
In version 2.0.0, only unexpected query parameters will cause a 422 response from `OpenApiSpex.Plug.Cast`, this may be extended in future versions to detect more invalid requests.
