    • #5552: Exported metadata contains only methods metadata and no longer contains URI metadata.


    • #5653: Added integration test case for Swagger with circular references.


    • #5622: Update documentation for "Decode Response" parameter.


    • #5630: Add support for multipart/form-data in Content Type parameter. multipart/form-data will be prioritised as a default value if the Swagger method has formData fields of type file.
    • #5630: Add an enum property choice of application/wwww-form-urlencoded and multipart/form-data to Content Type parameters when Swagger method has formData parameters which are not type file and do not define consumes.
    • #5630: Change the default value for Content Type parameters to application/wwww-form-urlencoded, falling back to multipart/form-data and then the first consumes value when either values exist inside the Swagger method's consumes.
    • #5640: Fix issue where charset is stripped from the default value for Content Type parameters in some cases.


    • #5432: It now adds additional information for formData parameters while converting the swagger parameters to json-schema properties


    • #5432: It now respects swagger consumes and produces properties while converting swagger definitions to flow node specs


    • #4919: Now exports spec and metadata
    • #4918: Breaking Change: Adds authorizations to the spec
    • #5358: Breaking Change: A Default output is created for all flow-nodes regardless of the swagger definition.
    • #5358: Breaking Change: An Error output is created for all flow-nodes to allow routing on connection errors.
    • #5358: The default JSONPath selector for all outputs is now $.response. Only the Error output defaults to $.error.


    • #5111: Fixed bug where swagger documents with extensions in the same location as path methods failed to load correctly.


    • #5112: Previously, schemas generated from a swagger document with no "definitions" section was returned as undefined. Now, an empty array will be returned instead.


    • #4757: Changed SCM repository and associated internal cleanup.
    • #4860: Previously, api-builder-plugin-fn-swagger would throw "Error: Invalid reference token" when attempting to handle URI encoded JSON schema references in Swagger files. Now, invalid reference errors are not thrown.
