* Align `DefaultHeader` method terminology, deprecating previous methods. [#2510]
* Response service types in `ErrorHandlers` middleware now use `ServiceResponse<EitherBody<B>>` to allow changing the body type. [#2515]
* Both variants in `ErrorHandlerResponse` now use `ServiceResponse<EitherBody<B>>`. [#2515]
* Rename `test::{default_service => simple_service}`. Old name is deprecated. [#2518]
* Rename `test::{read_response_json => call_and_read_body_json}`. Old name is deprecated. [#2518]
* Rename `test::{read_response => call_and_read_body}`. Old name is deprecated. [#2518]
* Relax body type and error bounds on test utilities.
### Removed
* Top-level `EitherExtractError` export. [#2510]
* Conversion implementations for `either` crate. [#2516]
* `test::load_stream` and `test::load_body`; replace usage with `body::to_bytes`. [#2518]
