# Changes
## Unreleased - 2021-xx-xx
### Added
- `impl Hash` for `http::header::Encoding`. [#2501]
- `AcceptEncoding::negotiate()`. [#2501]
### Changed
- `AcceptEncoding::preference` now returns `Option<Preference<Encoding>>`. [#2501]
- Rename methods `BodyEncoding::{encoding => encode_with, get_encoding => preferred_encoding}`. [#2501]
- `http::header::Encoding` now only represents `Content-Encoding` types. [#2501]
### Fixed
- Auto-negotiation of content encoding is more fault-tolerant when using the `Compress` middleware. [#2501]
### Removed
- `Compress::new`; restricting compression algorithm is done through feature flags. [#2501]
[#2501]: https://github.com/actix/actix-web/pull/2501

# Changes
## Unreleased - 2021-xx-xx
### Added
- `impl Eq` for `header::ContentEncoding`. [#2501]
- `impl Copy` for `QualityItem` where `T: Copy`. [#2501]
- `Quality::ZERO` equivalent to `q=0`. [#2501]
- `QualityItem::zero` that uses `Quality::ZERO`. [#2501]
- `ContentEncoding::to_header_value()`. [#2501]
### Changed
- `Quality::MIN` is now the smallest non-zero value. [#2501]
- `QualityItem::min` semantics changed with `QualityItem::MIN`. [#2501]
- Rename `ContentEncoding::{Br => Brotli}`. [#2501]
- Minimum supported Rust version (MSRV) is now 1.54.
### Fixed
- `ContentEncoding::Identity` can now be parsed from a string. [#2501]
- A `Vary` header is now correctly sent along with compressed content. [#2501]
### Removed
- `ContentEncoding::Auto` variant. [#2501]
- `ContentEncoding::is_compression()`. [#2501]
