## 4.3.3

**`(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
  }
)
```
