 ## Unreleased - 2021-xx-xx
+### Added
+* Methods on `AcceptLanguage`: `ranked` and `preference`. [#2480]
+* `AcceptEncoding` typed header. [#2482]
+* `Range` typed header. [#2485]
+* `HttpResponse::map_into_{left,right}_body` and `HttpResponse::map_into_boxed_body`. [#2468]
+* `ServiceResponse::map_into_{left,right}_body` and `HttpResponse::map_into_boxed_body`. [#2468]
+* `HttpServer::on_connect` now receives a `CloneableExtensions` object. [#2327]

+### Changed
+* Rename `Accept::{mime_precedence => ranked}`. [#2480]
+* Rename `Accept::{mime_preference => preference}`. [#2480]
+* Un-deprecate `App::data_factory`. [#2484]

 # Changes
 
 ## Unreleased - 2021-xx-xx
+### Added
+* Add timeout for canceling HTTP/2 server side connection handshake. Default to 5 seconds. [#2483]
+* HTTP/2 handshake timeout can be configured with `ServiceConfig::client_timeout`. [#2483]
+* `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]
+* `header::QualityItem::{max, min}`. [#2486]
+* `header::Quality::{MAX, MIN}`. [#2486]
+* `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]
+* `http` module. Most everything it contained is exported at the crate root. [#2488]
