   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:
+  - `compress-brotli`
+  - `compress-gzip`
+  - `compress-zstd`
+  If you have set in your `Cargo.toml` dedicated `actix-web` features and you still want
+  to have compression enabled. Please change features selection like bellow:
+
+  Before: `"compress"`
+  After: `"compress-brotli", "compress-gzip", "compress-zstd"`
+

+
+## 0.5.0-beta.1 - 2021-07-20

+
+## 0.4.0 - 2021-06-06
+* When matching path parameters, `%25` is now kept in the percent-encoded form; no longer decoded to `%`. [#357]
+* Path tail patterns now match new lines (`\n`) in request URL. [#360]
+* Fixed a safety bug where `Path` could return a malformed string after percent decoding. [#359]
