In the improved Python SDK, fields of a custom type can now differentiate between a nullable value and a missing value and will operate according to the behavior of the type specified. This way you can either pass a value that corresponds to the type specified, use null as a value or skip the field altogether depending upon the defined behavior of the field.

OAS allows you to set optional/required properties in models. While serializing a model, optional properties will be omitted if the value of property is not set (i.e. initialized with null) and, required properties will be serialized in any case. This is a case of factoring schema in oneOf/anyOf. Now with this support, you can define properties with the same names but with different optional/required constraints in request/response of an endpoint.

APIMatic CodeGen has now added support to configure the default Faraday connection with available Faraday adapters in Ruby SDKs.

APIMatic’s Self Hosted Portal offering has been augmented with the following enhancements:

• API Specification export
• Detailed and informative exception messages
• Ignore MacOS specific files in build input

APIMatic announces the support for multiple authenticaion schemes in Python SDKs. With the new design, it has become quite easy to configure multiple authentication schemes per SDK. All of the auth managers are instantiated at the start during the client initialization. After that their relevant auth managers can be used to apply auth schemes per endpoint as required in SDK.

We are now dropping support for Ruby version 2.5 in Ruby SDKs. Ruby 2.5 hit EOL status on 2021-03-31 as per the official source. As a result of dropping Ruby 2.5, we are now able to relax version constraints on some of the Ruby SDKs dependencies.

OpenAPI Specification allows you to add an object type in oneOf and anyOf in Java SDKs. Defining an object type means any key/value pair is accepted. Object type in Java means it can refer to any instance, as Object is the root class. Therefore, this change enforces that for any object type case falling under oneOf and anyOf, the Java SDK will treat it as Map.

PHP SDKs now support complex query parameters with which you can send a complex type as well as arrays/maps of complex types in query strings.

OAS allows marking properties as nullable, but previously this flag was not being respected in the Java SDK where oneOf/anyOf was being used. Now with this release, the Java SDK fully respects the nullable attribute during serialization & deserialization for oneOf/anyOf properties.

Java SDKs now support enum types defined as oneOf/anyOf types. You can define as many distinct enum types as required with this support.
