# Changes

## Unreleased - 2020-xx-xx
### Changed
* `PayloadConfig` is now also considered in `Bytes` and `String` extractors when set
  using `App::data`. [#1610]
* `web::Path` now has a public representation: `web::Path(pub T)` that enables
  destructuring. [#1594]
* `ServiceRequest::app_data` allows retrieval of non-Data data without splitting into parts to
  access `HttpRequest` which already allows this. [#1618]
* MSRV is now 1.42.0.

### Fixed
* Memory leak of app data in pooled requests. [#1609]
