## 4.13.0

**`(feat):`** Adds support for overriding literal global headers in the client constructor (e.g. `version`).

```python
client = Acme(
  ...
  version="1.0.0",
)
```

## 4.12.1

**`(fix):`** Fixes an issue where dictionary types defined within TypedDicts incorrectly used the
`typing_extensions.NotRequired` type.

**`(fix):`** Fixes an issue where optional `core.File` parameters would cause `mypy` failures.

**`(fix):`** Fixes a regression introduced in 4.12.0, where the non raw response client endpoints
did not respect the allowed method keywords (e.g. `list` was generated as `list_`).

## 4.12.0

**`(fix):`** Resolve issues with paginated endpoints generating incorrect endpoint return types.
