+### Fixed
+- Auto-negotiation of content encoding is more fault-tolerant when using the `Compress` middleware. [#2501]
+- Scope and Resource middleware can access data items set on their own layer. [#2288]
+- Multiple calls to `App::data()` with the same type now keeps the latest call's data. [#1906]
+- Typed headers containing lists that require one or more items now enforce this minimum. [#2482]
+- `dev::ConnectionInfo::peer_addr` will no longer return the port number. [#2554]
+- `dev::ConnectionInfo::realip_remote_addr` will no longer return the port number if sourcing the IP from the peer's socket address. [#2554]
+- Accept wildcard `*` items in `AcceptLanguage`. [#2480]
+- Relax `Unpin` bound on `S` (stream) parameter of `HttpResponseBuilder::streaming`. [#2448]
+- Fix quality parse error in `http::header::AcceptEncoding` typed header. [#2344]
+- Double ampersand in `middleware::Logger` format is escaped correctly. [#2067]
+- Added the underlying parse error to `test::read_body_json`'s panic message. [#1812]
+
+### Security
+- `cookie` upgrade addresses [`RUSTSEC-2020-0071`].
