# Changes
## Unreleased - 2021-xx-xx
### Added
* `impl<T: MessageBody> MessageBody for Pin<Box<T>>`. [#2152]
### Changes
* The type parameter of `Response` no longer has a default. [#2152]
* The `Message` variant of `body::Body` is now `Pin<Box<dyn MessageBody>>`. [#2152]
* `BodyStream` and `SizedStream` are no longer restricted to Unpin types. [#2152]
### Removed
* `cookies` feature flag. [#2065]
* Top-level `cookies` mod (re-export). [#2065]
