# Changes
## Unreleased - 2021-xx-xx
### Changed
* Compress middleware's response type is now `AnyBody<Encoder<B>>`. [#2448]
### Fixed
* Relax `Unpin` bound on `S` (stream) parameter of `HttpResponseBuilder::streaming`. [#2448]
### Removed
* `dev::ResponseBody` re-export; is function is replaced by the new `dev::AnyBody` enum. [#2446]
[#2423]: https://github.com/actix/actix-web/pull/2423

## Unreleased - 2021-xx-xx
### Added
* `AnyBody::empty` for quickly creating an empty body. [#2446]
* `body::AnyBody::empty` for quickly creating an empty body. [#2446]
* `impl Clone` for `body::AnyBody<S> where S: Clone`. [#2448]
* `body::AnyBody::into_boxed` for quickly converting to a type-erased, boxed body type. [#2448]
### Changed
* Rename `AnyBody::{Message => Stream}`. [#2446]
* Rename `body::AnyBody::{Message => Body}`. [#2446]
* Rename `body::AnyBody::{from_message => new_boxed}`. [#2448]
* Rename `body::AnyBody::{from_slice => copy_from_slice}`. [#2448]
* Rename `body::{BoxAnyBody => BoxBody}`. [#2448]
* Change representation of `AnyBody` to include a type parameter in `Body` variant. Defaults to `BoxBody`. [#2448]
* `Encoder::response` now returns `AnyBody<Encoder<B>>`. [#2448]
### Removed
* `AnyBody::Empty`; an empty body can now only be represented as a zero-length `Bytes` variant. [#2446]
* `BodySize::Empty`; an empty body can now only be represented as a `Sized(0)` variant. [#2446]
* `body::AnyBody::Empty`; an empty body can now only be represented as a zero-length `Bytes` variant. [#2446]
* `body::BodySize::Empty`; an empty body can now only be represented as a `Sized(0)` variant. [#2446]
* `EncoderError::Boxed`; it is no longer required. [#2446]
* `body::ResponseBody`; is function is replaced by the new `body::AnyBody` enum. [#2446]
