### Fixed
* Double ampersand in Logger format is escaped correctly. [#2067]
### Changed
* `CustomResponder` would return error as `HttpResponse` when `CustomResponder::with_header` failed instead of skipping.
(Only the first error is kept when multiple error occur) [#2093]
### Removed
* The `client` mod was removed. Clients should now use `awc` directly.
