* `Response::map_into_boxed_body`. [#2468]
* `body::EitherBody` enum. [#2468]
* `body::None` struct. [#2468]
* Impl `MessageBody` for `bytestring::ByteString`. [#2468]
* `impl Clone for ws::HandshakeError`. [#2468]
* `#[must_use]` for `ws::Codec` to prevent subtle bugs. [#1920]
* `impl Default ` for `ws::Codec`. [#1920]

* `impl Display` for `header::Quality`. [#2486]
* `CloneableExtensions` object for use in `on_connect` handlers. [#2327]
### Changed
* Rename `body::BoxBody::{from_body => new}`. [#2468]
* Body type for `Responses` returned from `Response::{new, ok, etc...}` is now `BoxBody`. [#2468]
* The `Error` associated type on `MessageBody` type now requires `impl Error` (or similar). [#2468]
* Error types using in service builders now require `Into<Response<BoxBody>>`. [#2468]
* `From` implementations on error types now return a `Response<BoxBody>`. [#2468]
* `ResponseBuilder::body(B)` now returns `Response<EitherBody<B>>`. [#2468]
* `ResponseBuilder::finish()` now returns `Response<EitherBody<()>>`. [#2468]
* `on_connect_ext` methods now receive a `CloneableExtensions` object. [#2327]
### Removed
* `ResponseBuilder::streaming`. [#2468]
* `impl Future` for `ResponseBuilder`. [#2468]
* Remove unnecessary `MessageBody` bound on types passed to `body::AnyBody::new`. [#2468]
* Move `body::AnyBody` to `awc`. Replaced with `EitherBody` and `BoxBody`. [#2468]
* `impl Copy` for `ws::Codec`. [#1920]
* `header::qitem` helper. Replaced with `header::QualityItem::max` [#2486]
* `impl TryFrom<u16>` for `header::Quality` [#2486]

## 3.0.0-beta.14 - 2021-11-30
### Changed
* Guarantee ordering of `header::GetAll` iterator to be same as insertion order. [#2467]
* Expose `header::map` module. [#2467]
* Implement `ExactSizeIterator` and `FusedIterator` for all `HeaderMap` iterators. [#2470]
* Update `actix-tls` to `3.0.0-rc.1`. [#2474]

## 3.0.0-beta.13 - 2021-11-22
### Added
* `body::AnyBody::empty` for quickly creating an empty body. [#2446]
* `body::AnyBody::none` for quickly creating a "none" body. [#2456]
* `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 `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
* `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]
