# 0.2.0 (December 1, 2021)
## Added
- **builder**: Add `ServiceBuilderExt` which adds methods to `tower::ServiceBuilder` for
adding middleware from tower-http ([#106])
- **request_id**: Add `SetRequestId` and `PropagateRequestId` middleware ([#150])
- **trace**: Add `DefaultMakeSpan::level` to make log level of tracing spans easily configurable ([#124])
- **trace**: Add `LatencyUnit::Seconds` for formatting latencies as seconds ([#179])
- **trace**: Support customizing which status codes are considered failures by `GrpcErrorsAsFailures` ([#189])
- **compression**: Support specifying predicates to choose when responses should
be compressed. This can be used to disable compression of small responses,
responses with a certain `content-type`, or something user defined ([#172])
- **fs**: Ability to serve precompressed files ([#156])
- **fs**: Support `Range` requests ([#173])
- **fs**: Properly support HEAD requests which return no body and have the `Content-Length` header set ([#169])
## Changed
- `AddAuthorization`, `InFlightRequests`, `SetRequestHeader`,
`SetResponseHeader`, `AddExtension`, `MapRequestBody` and `MapResponseBody`
now requires underlying service to use `http::Request<ReqBody>` and
`http::Response<ResBody>` as request and responses ([#182]) (BREAKING)
- **set_header**: Remove unnecessary generic parameter from `SetRequestHeaderLayer`
and `SetResponseHeaderLayer`. This removes the need (and possibility) to specify a
body type for these layers ([#148]) (BREAKING)
- **compression, decompression**: Change the response body error type to
`Box<dyn std::error::Error + Send + Sync>`. This makes them usable if
the body they're wrapping uses `Box<dyn std::error::Error + Send + Sync>` as
its error type which they previously weren't ([#166]) (BREAKING)
- **fs**: Change response body type of `ServeDir` and `ServeFile` to
`ServeFileSystemResponseBody` and `ServeFileSystemResponseFuture` ([#187]) (BREAKING)
- **auth**: Change `AuthorizeRequest` and `AsyncAuthorizeRequest` traits to be simpler ([#192]) (BREAKING)
## Removed
- **compression, decompression**: Remove `BodyOrIoError`. Its been replaced with `Box<dyn
std::error::Error + Send + Sync>` ([#166]) (BREAKING)
- **compression, decompression**: Remove the `compression` and `decompression` feature. They were unnecessary
and `compression-full`/`decompression-full` can be used to get full
compression/decompression support. For more granular control, `[compression|decompression]-gzip`,
`[compression|decompression]-br` and `[compression|decompression]-deflate` may
be used instead ([#170]) (BREAKING)

# 0.1.2 (November 13, 2021)
- New middleware: Add `Cors` for setting [CORS] headers ([#112])
- New middleware: Add `AsyncRequireAuthorization` ([#118])
- `Compression`: Don't recompress HTTP responses ([#140])

# 0.1.1 (July 2, 2021)
- Add example of using `SharedClassifier`.
- Add `StatusInRangeAsFailures` which is a response classifier that considers
responses with status code in a certain range as failures. Useful for HTTP
clients where both server errors (5xx) and client errors (4xx) are considered
failures.
- Implement `Debug` for `NeverClassifyEos`.
- Update iri-string to 0.4.
- Add `ClassifyResponse::map_failure_class` and `ClassifyEos::map_failure_class`
for transforming the failure classification using a function.
- Clarify exactly when each `Trace` callback is called.
- Add `AddAuthorizationLayer` for setting the `Authorization` header on
requests.
# 0.1.0 (May 27, 2021)
- Initial release.
