- version: 4.22.1-rc0
  changelogEntry:
    - summary: |
        Lazily validate model serialization to reduce memory consumption. Pydantic 2.11.0 introduced an issue where the model_serializer 
        decorator set to wrap mode forced it to eagerly do schema validation at import time. Because we had this decorator on the UniversalBaseModel,
        it would try to validate the schemas of all the Model types at import time. This caused massive memory spikes for more complex SDKs, up to 2.6GB
        in some cases. This change essentially accomplishes the same logic of wrapping the serialization process and modifying the serialization
        structure of datetime fields. The difference is that we manually wrap, so we're able to defer model validation until runtime, drastically
        reducing our memory consumption.

          Pydantic V2 `.dict` calls are updated to be back to pre-3.10.4 logic.
          This is fix a regression where nested literals were being omitted due to the Pydantic V2 serializers not respecting the recursive .dict logic, as
          Pydantic V2 shells out `model_dump` calls to Rust library and serializers, as opposed to recursively calling `model_dump`.

          It is expected that performance will not be degraded given the Rust-based serializers have optimized performance, compared to the Pydantic V1 .dict approach.

          Pydantic field aliases are removed and replaced with an internal
          representation. This allows for more robust handling of field aliases
          and prevents issues with Pydantic V2 and mypy.

          Previously, you'd have for V1 and V2 compatibility in Pydantic, you'd want to conditionally apply the config class within
          the base model, however this would lead to mypy errors when filling out a model with it's field alias. To solve this, We
          used the deprecated `class Config`, regardless of the Pydantic version to satisfy mypy, which lead to warnings in the console.

          Now, we've removed the field aliases and replaced them with an internal representation, which allows us to avoid pydantic config altogether.

      summary: Add support for a RequestOptions object for each generated function within Python SDKs
      changed:
        - >-
          Add support for a RequestOptions object for each generated
          function within Python SDKs. This parameter is an optional final
          parameter that allows for configuring timeout, as well as pass in
          arbitrary data through to the request. RequestOptions is a TypedDict,
          with optional fields, so there's no need to instantiate an object, just
          pass in the relevant keys within a dict!

          Acknowledge the optionality of a `File` property, previously we were
          requiring all `File` type inputs, even if they were specified as
          optional within the OpenAPI or Fern definition. Now, we check if the
          parameter is required and make the parameter optional if it is not.

          The Python SDK better handles cyclical references. In particular,
          cyclical references are tracked for undiscriminated unions, and
          update_forward_refs is always called with object references.
