using `NormalizePath::default()`. As such, calling `NormalizePath::default()` will log a warning.
It is advised that the `new` method be used instead.
Before: `#[get("/test/")]`
After: `#[get("/test")]`
Alternatively, explicitly require trailing slashes: `NormalizePath::new(TrailingSlash::Always)`.
* The `type Config` of `FromRequest` was removed.
* Feature flag `compress` has been split into its supported algorithm (brotli, gzip, zstd).
By default all compression algorithms are enabled.
To select algorithm you want to include with `middleware::Compress` use following flags:

## Unreleased - 2021-xx-xx
## 0.4.0-beta.9 - 2021-12-01
* Polling `Field` after dropping `Multipart` now fails immediately instead of hanging forever. [#2463]
[#2463]: https://github.com/actix/actix-web/pull/2463
## 0.4.0-beta.8 - 2021-11-22
* Ensure a correct Content-Disposition header is included in every part of a multipart message. [#2451]
* Added `MultipartError::NoContentDisposition` variant. [#2451]
* Since Content-Disposition is now ensured, `Field::content_disposition` is now infallible. [#2451]
* Added `Field::name` method for getting the field name. [#2451]
* `MultipartError` now marks variants with inner errors as the source. [#2451]
* `MultipartError` is now marked as non-exhaustive. [#2451]
[#2451]: https://github.com/actix/actix-web/pull/2451
## 0.4.0-beta.7 - 2021-10-20
* Minimum supported Rust version (MSRV) is now 1.52.
## 0.4.0-beta.6 - 2021-09-09
* Minimum supported Rust version (MSRV) is now 1.51.
## 0.4.0-beta.5 - 2021-06-17
* No notable changes.
