-## 3.11.0-rc0
-**`(chore):`** Remove Pydantic field aliases and leverage an internal representation.
-
-### What's been fixed
-- 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.

-- 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.

+**`(fix):`** The generator now writes the reference.md configuration correctly, using `.dict()` instead of `.json()`.
+
+
+## 4.3.2
+**`(fix):`** The generator will now correctly default to the configured global `default_bytes_stream_chunk_size` when the `request_options` parameter is not provided.
+
+
+## 4.3.1
+**`(feat):`** Requests for file download will now allow users to pass in a `chunk_size` option that allows them to receive chunks of a specific size
+from the resultant `iter_bytes` invocation on the response byte stream.
+
+Concretely, a user would leverage the following:
+```python
+client.download(
+  ...,
+  request_options={
+    "chunk_size": 1024    # 1MB
+  }
+)
+```
+
+
+## 4.2.8
+**`(fix):`** The snippet writer now correctly handles base64 strings.
+
+
+## 4.2.7
+**`(fix):`** The generated README will now have a section that links to the generated
+SDK Reference (in `reference.md`).
+
+```md
+## Reference
+
+A full reference for this library can be found [here](./reference.md).
+```
+
+
+## 4.2.7-rc4
+**`(fix):`** Generated readmes now include the parameter name required for the request options parameter within the example snippets.
+
+## 4.2.7-rc3
+**`(fix):`** Now, when sending Snippet Templates back to Fern, the generator will not try to coerce a potentially missing ID into the `api_definition_id` field.
+This, had been a cause of the error log `Failed to upload snippet templates to FDR, this is ok: one of the hex, bytes, bytes_le, fields, or int arguments must be given`.
+
+
+## 4.2.7-rc2
+**`(fix):`** Pydantic utilities now correctly handles cases where you have a Pydantic model, with a list of pydantic models as a field, where those models have literals.
+Effectively, `deep_union_pydantic_objects` now handles lists of objects and merges them appropriately.
+
+
+## 4.2.7-rc1
+**`(fix):`** When leveraging the `include_union_utils` configuration flag, the Pydantic models will no longer include transitive dependencies within
+`update_forward_ref` calls, since these should not be necessary. This effectively scopes back the changes introduced in 4.0.0-rc5, which included
+changes to improve circular reference handling in Pydantic models.
+
+
+## 4.2.7-rc0
+**`(fix):`** Dynamic header suppliers, as used within the OAuth provider are now invoked on every request, not just the first.
+This was a regression introduced within an earlier version that is now fixed. As a results of this fix, the `refresh_token` is now correctly refreshed.
+
+
+## 4.2.6
+**`(fix):`** Serialization utilities (necessary when pydantic aliases are removed) now respects dictionaries as well.
+
+
+## 4.2.5
+**`(fix):`** Parameters of file upload functions now default to OMIT, not None, so that the SDK appropriately
+filters out unset parameters, while still allowing for user specified None values.
+
+
+## 4.2.4
+**`(fix):`** Datetime examples are generated correctly once again.
+The `pydantic_utilities` file is python 3.8 compatible.
+
+
+## 4.2.3
+**`(fix):`** The content type of file properties is now respected for multipart
+requests. For example, if you have a file property called `image` that has the
+content type `image/jpeg`, then it will be sent as:
+
+```python
+"image": core.with_content_type(file=image, content_type="image/jpeg"),
+````
+
+
+## 4.2.2
+**`(fix):`** The content type of non-file properties is now respected for multipart
+requests. For example, if you have a type called `metadata` that has the
+content type `application/json`, then it will be sent as:
+
+```python
+"metadata": (None, json.dumps(jsonable_encoder(metadata)), "application/json"),
+```
+
+
+## 4.2.1
+**`(fix):`** When the generator runs bash commands such as `poetry install` and there is a failure,
+now the `stderr` and `stdout` is logged to help improve user debugging.
+
+
+## 4.2.0
+**`(feat):`** Allow specifying arbitrary configuration to your packages `pyproject.toml` by adding a `pyproject_toml` block to your configuration
+whatever you include in this block will be added as-is to the `pyproject.toml` file. The config, as an example is:
+
+```yaml
+config:
+  pyproject_toml: |
+    [tool.covcheck.group.unit.coverage]
+    branch = 26.0
+    line = 62.0
+
+    [tool.covcheck.group.service.coverage]
+    branch = 30.0
+    line = 67.0
+```
+
+
+## 4.1.0
+**`(feat):`** Allow specifying pip extras within your `pyproject.toml`. The following config:
+
+```yaml
+config:
+  extra_dev_dependencies:
+    covcheck:
+      version: "^0.4.3"
+      extras: ["toml"]
+```
+
+would add the following to your `pyproject.toml`:
+
+```toml
+[tool.poetry.dev-dependencies]
+covcheck = { version = "^0.4.3", extras = ["toml"] }
+```
+
+
+## 4.0.0
+**`(fix):`** Generated tests that expect an empty result when they are of type `text` (not JSON) now appropriately expect an empty string instead of `None` for async functions as well.
+Version 3.3.4 fixed this for sync functions only, which was a bug.
+
+
+## 4.0.0-rc9
+**`(fix):`** All Pydantic V2 warnings have been resolved
+
+### What's been fixed
+- json_encoders have been removed from Pydantic V2, and replaced with a `model_serializer` method.
+- additional model construction functions have been added when not leveraging pydantic field aliases to allow users to construct a model from JSOn without the need for dealiasing the object themselves.
+
+## 4.0.0-rc8
+**`(fix):`** Pydantic models that call `update_forward_refs` on non-union circular reference dependencies now pass in `localns` for
+the current member, a field in Pydantic V1 that provides object contexts to models in the event objects are not fully rebuilt.
+
+
+## 4.0.0-rc7
+**`(fix):`** The generator now respects the old use_str_enums flag again, a regression was introduced where only the new flag `enum_type`
+was respected.
+
+
+## 4.0.0-rc6
+**`(fix):`** Pydantic models now call update forward refs on non-union circular references. This
+prevents runtime errors in certain cases where types self reference itself through
+a union.
+
+
+## 4.0.0-rc5
+**`(fix):`** Pydantic models now call update forward refs on non-union circular references. This
+prevents runtime errors in certain cases where types self reference itself through
+a union.
+
+
+## 4.0.0-rc4
+**`(fix):`** Pydantic models now call update forward refs on non-union circular references. This
+prevents runtime errors in certain cases where types self reference itself through
+a union.
+
+
+## 4.0.0-rc3
+**`(fix):`** Pydantic models now call update forward refs on non-union circular references. This
+prevents runtime errors in certain cases where types self reference itself through
+a union.
+
+
+## 4.0.0-rc2
+**`(fix):`** Update .dict calls in Pydantic V2 to be back to pre-3.10.4 logic for SDKs that continue using Pydantic aliases.
+
+## 4.0.0-rc1
+**`(fix):`** Update .dict calls in Pydantic V2 to be back to pre-3.10.4 logic.
+
+### What's been fixed
+- 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.
+
+## 4.0.0-rc0
+**`(fix):`** Rerelease 3.11.0-rc0 as a major version, with a configuration flag to disable the behavior (`use_pydantic_field_aliases`), defaulted to `true` to preserve existing behavior.
+
+**`(internal):`** The generator now shares "as is" files with Pydantic and FastAPI generators.
+
+### What's been fixed
+- Rerelease 3.11.0-rc0 as a major version, with a configuration flag to disable the behavior (`use_pydantic_field_aliases`), defaulted to `false` to introduce the break on a major version.
+To maintain parity with pre-3.11.0 behavior, update the flag to `true`:
+
+  ```yaml
+  - name: fernapi/fern-python-sdk
+    version: 4.0.0-rc0
+    config:
+      pydantic_config:
+        use_pydantic_field_aliases: true
+  ```
+
+## 3.11.0-rc0
+**`(chore):`** Remove Pydantic field aliases and leverage an internal representation.
+
+### What's been fixed
+- 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.
+
+## 3.10.8
+**`(fix):`** Allow for fields prefixed with the name `model`, a silent break introduced in Pydantic V2.
+
+## 3.10.7
+**`(fix):`** When not leveraging mock integration tests, still run pytest over everything, not a specific directory.
+
