 ## Unreleased
 
+## 4.12.0

 - `actix_web::response::builder::HttpResponseBuilder::streaming()` now sets `Content-Type` to `application/octet-stream` if `Content-Type` does not exist.
-- `actix_web::response::builder::HttpResponseBuilder::streaming()` now calls `actix_web::response::builder::HttpResponseBuilder::no_chunking()` if `Content-Length` is set by user.
+- `actix_web::response::builder::HttpResponseBuilder::streaming()` now calls `actix_web::response::builder::HttpResponseBuilder::no_chunking()` and returns `SizedStream` if `Content-Length` is set by user.
 - Add `ws` crate feature (on-by-default) which forwards to `actix-http` and guards some of its `ResponseError` impls.
 - Add public export for `EitherExtractError` in `error` module.
