- Add `tcp_keepalive` option to `blocking::ClientBuilder`.
- Add `multipart::Part::stream_with_length` constructor, to create a streaming part with a known length.
- Add `ClientBuilder::https_only` option, to allow requiring URLs to be `https`.
- Change default `tcp_keepalive` value to be disabled.

## v0.10.9

- Add `rustls-tls-native-roots`, `rustls-tls-webpki-roots`, and `rustls-tls-manual-roots` Cargo features, to configure which certificate roots to use with rustls.
- Add `ClientBuilder::tcp_keepalive()` method to enable TCP keepalive.
- Add `ClientBuilder::http1_writev()` method to force enable or disable vectored writes.
- Add `Error::is_connect()` method to identify if the error is related to connection-establishment.

- Fix Windows system proxy detection of Fiddler proxies.
- (wasm) Add `headers` method to `RequestBuilder`.
- (wasm) Add `execute` method to `Client`.
- (wasm) Add `TryFrom<http::Request>` for `Request`.
- (wasm) Fix checking for global `window` to work in non-browser environments.
- (wasm) Fix sending of an empty body when not required.

## v0.10.7

- Add `NO_PROXY` environment variable support.
- Add more `Error::{is_request, is_body, is_decode}` getters.
- Add conversion of `reqwest::ClientBuilder` to `reqwest::blocking::ClientBuilder`.
- Add `headers_mut()` to `reqwest::blocking::Response`.
- (wasm) Add `form()`, `query()`, `multipart` and `bearer_auth()` to `RequestBuilder`.

## v0.10.6

- Changed handling of URLs that don't have `http:` or `https:` schemes, returning an error instead.
- Fixed a potential hyper-rustls feature conflict.

## v0.10.5

- Add `ClientBuilder::pool_idle_timeout` option.
- Add `ClientBuilder::pool_max_idle_per_host` option, deprecate `max_idle_per_host`.

- Change to enable system/environment proxy detection by default.
- Change `default-tls` feature to only include `ClientBuilder` options that both `native-tls` and `rustls` support.
- Change default feature set to reduce unnecessary dependencies. Most features are disabled by default:
  - `blocking`: The `reqwest::blocking` (synchronous) client API.
  - `cookies`: Cookie store support.

  - `json`: Request and response JSON body methods.
  - `stream`: `futures::Stream` support.
- Change `Error` internal design, removing several `Error::is_*` inspector methods.

  - Renamed types to be part of the `redirect` module (for example, `reqwest::RedirectPolicy` is now `reqwest::redirect::Policy`).
  - Removed `loop_detected` and `too_many_redirect` methods from `redirect::Attempt`, replaced with a generic `error` method.
  - The default policy no longer specifically looks for redirect loops (but they should be caught by the maximum limit).

- Fix checking `HTTP_PROXY` environment variable if it the environment is from a CGI script.
- Fix removal of username/password of parsed proxy URL.

- Update `url` to v2.0.
- Update `hyper` to v0.13.
- Update `http` to v0.2.


## v0.9.19

- Add `ClientBuilder::use_sys_proxy()` to enable automatic detect of HTTP proxies configured on the system.
- Add `ClientBuilder::no_proxy()` to disable system proxies. This is the default for 0.9, but will change to detecting system proxies by default in 0.10.
- Add support for streaming request bodies in the async client.
- Add `async::Response::text()` that returns a `Future` of the full body decoded to a `String`.

- Add optional support for SOCKS5 proxies, by enabling the `socks5` cargo feature.
- Add Cookie Store support to `Client`, automatically handling cookies for a session.
* Add `ClientBuilder::cookie_store(enable: bool)` method to enable a cookie store that persists across requests.
* Add `Response::cookies()` accessor that allows iterating over response cookies.
- Fix `Proxy` to check the URL for a username and password.

## v0.9.13

### Fixes

- Fix panic on some invalid `Location` headers during redirects (error is logged and redirect response is returned instead).
- Fix instance when server notices streaming request body is complete before reqwest does.

# v0.9.0

### Features

- Upgrade to `tokio` 0.1.
- Upgrade to `hyper` 0.12.
- Upgrade to `native-tls` 0.2.
- Add `ClientBuilder::danger_accept_invalid_certs(bool)` to disable
  certificate verification.
- Add `RequestBuilder::bearer_auth(token)` to ease sending bearer tokens.
- Add `headers()` and `headers_mut()` to `multipart::Part` to allow sending
  extra headers for a specific part.
- Moved `request::unstable::async` to `reqwest::async`.

### Fixes

- Fix panicking when passing a `Url` with a `file://` scheme. Instead, an
  `Error` is returned.

### Breaking Changes

- Changed `ClientBuilder::danger_disable_hostname_verification()`
  to `ClientBuilder::danger_accept_invalid_hostnames(bool)`.
- Changed `ClientBuilder` to be a by-value builder instead of by-ref.

  For single chains of method calls, this shouldn't affect you. For code that
  conditionally uses the builder, this kind of change is needed:

  ```rust
  // Old
  let mut builder = ClientBuilder::new();
  if some_val {
      builder.gzip(false);
  }
  let client = builder.build()?;

  // New
  let mut builder = ClientBuilder::new();
  if some_val {
      builder = builder.gzip(false);
  }
  let client = builder.build()?;
  ```
- Changed `RequestBuilder` to be a by-value builder of by-ref.

  See the previous note about `ClientBuilder` for affected code and
  how to change it.
- Removed the `unstable` cargo-feature, and moved `reqwest::unstable::async`
  to `reqwest::async`.
- Changed `multipart::Part::mime()` to `mime_str()`.

  ```rust
  // Old
  let part = multipart::Part::file(path)?
      .mime(mime::TEXT_PLAIN);

  // New
  let part = multipart::Part::file(path)?
      .mime_str("text/plain")?;
  ```
- The upgrade to `hyper` 0.12 means a temporary removal of the typed headers.

  The `RequestBuilder` has simple methods to set headers using strings, which
  can work in most places.

  ```rust
  // Old
  client
      .get("https://hyper.rs")
      .header(UserAgent::new("hallo"))
      .send()?;

  // New
  client
      .get("https://hyper.rs")
      .header("user-agent", "hallo")
      .send()?;
  ```

  To ease the transition, there is a `hyper-011` cargo-feature that can be
  enabled.

  ```toml
  [dependencies]
  reqwest = { version = "0.9", features = ["hyper-011"] }
  ```

  And then usage:

  ```rust
  client
      .get("https://hyper.rs")
      .header_011(reqwest::hyper_011::header::UserAgent::new("hallo"))
      .send()?;
  ```


## v0.8.8

- Fix docs.rs/reqwest build.

## v0.8.7

### Fixes

- Send an extra CRLF at the end of multipart requests, since some servers expect it.
- Removed internal dependency on `tokio-proto`, which removed unsafe `small-vec`
  dependency.

## v0.8.6

### Features

- Add `RedirectAttempt::status` to check status code that triggered redirect.
- Add `RedirectPolicy::redirect` method publicly, to allow composing policies.

## v0.8.5

### Features

- Try to auto-detect encoding in `Response::text()`.
- Add `Certificate::from_pem` to load PEM encoded client certificates.
- Allow unsized types in `query`, `form`, and `json`.
- Add `unstable::async::RequestBuilder::query`, mirroring the stable builder method.

## v0.8.4

### Features

- Add `RequestBuilder::query` to easily adjust query parameters of requests.

## v0.8.3

### Features

- Upgrades internal log crate usage to v0.4

## v0.8.2

### Fixes

- Enable hyper's `no_proto` config, fixing several bugs in hyper.

## v0.8.1

### Features

- Add `ClientBuilder::default_headers` to set headers used for every request.
- Add `async::ClientBuilder::dns_threads` to set number of threads use for DNS.
- Add `Response::text` as shortcut to read the full body into a `String`.
- Add `Response::copy_to` as shortcut for `std::io::copy`.

# v0.8.0

### Features

- Client TLS Certificates (#43)
- GZIP decoding has been added to the **async** Client (#161)
- `ClientBuilder` and `RequestBuilder` hold their errors till consumed (#189)
- `async::Response::body()` now returns a reference to the body instead of consuming the `Response`
- A default timeout for `reqwest::Client` is used set to 30 seconds (#181)

### Breaking Changes

- `Client::new` no longer returns a `Result`.

  To handle any panics that come from `Client::new`, the builder can be used instead.
- `ClientBuilder` and `RequestBuilder` hold their errors till consumed (#189).

  This means a bunch of `?` will be going away, but means using the builders will be far easier now. Any error encountered inside the builders will now be returned when the builder is consumed.

  To get errors back immediately, the `Request` type can be used directly, by building pieces separately and calling setters.
- `async::Response::body()` now returns a reference to the body instead of consuming the `Response`.
- A default timeout for `reqwest::Client` is used set to 30 seconds (#181)

  For uses where the timeout is too short, it can be changed on the `ClientBuilder`, using the `timeout` method. Passing `None` will disable the timeout, reverting to the pre-0.8 behavior.

## v0.7.3

### Features

- `Proxy::custom(fn)` to allow dynamically picking a proxy URL

### Fixes

- fix occasional panic when program exits while `Client` or `Response` are dropping.

## v0.7.2

### Fixes

- fix a panic when redirecting and a `Authorization<Basic>` header was added (https://github.com/seanmonstar/reqwest/commit/cf246d072badd9b31b487e7a0b00490e4cc9584f)
- fix redirects so that a GET will follow 307/308 responses (https://github.com/seanmonstar/reqwest/commit/2d11a4bd7167e1bf3a35b62f5aeb36d5d294e56e)

## v0.7.1

### Fixes

- fix remove accidental `println`s in the sending of a body
- some documentation improvements

# v0.7.0

### Features

- Proxy support (#30)
- Self-signed TLS certificates (#97)
- Disabling TLS hostname validation   (#89)
- A `Request` type that can be used instead of the `RequestBuilder` (#85)
- Add `Response::error_for_status()` to easily convert 400 and 500 status responses into an `Error`  (#98)
- Upgrade hyper to 0.11
  - Synchronous `Client` remains.
  - Timeouts now affect DNS and socket connection.
  - Pool much better at evicting sockets when they die.
  - An `unstable` Cargo feature to enable `reqwest::unstable::async`.
- A huge docs improvement! 

### Fixes

- Publicly exports `RedirectAction` and `RedirectAttempt`
- `Error::get_ref` returns `Error + Send + Sync`  

### Breaking Changes

- hyper has been upgraded to 0.11, so `header`, `StatusCode`, and `Method` have breaking changes.
- `mime` has been ugpraded to 0.3, with a very different API.
- All configuration methods have been removed from the `Client`, and moved to the `ClientBuilder`.
- The `HttpVersion` type was completely removed.
- `Error::cause()` now returns `Error::get_ref().cause()`.
- All methods on `Client` that start a `RequestBuilder` now return a `Result` immediately, instead of delaying the URL parse error for later.
- The `RequestBuilder` methods all take `&mut self`, instead of moving the builder, and return `&mut Self`. (This shouldn't actually affect most people who are building a request in a single chain.)
- `Response::status()` returns a `StatusCode` instead of `&StatusCode`.

## v0.6.2

### Features

- adds `Client::referer(bool)` option to disable setting the `Referer` header during redirects (https://github.com/seanmonstar/reqwest/commit/bafcd7ae6fc232856dd6ddb8bf5b20dbbbfe0bc9)

### Fixes

- fixes filtering sensitive headers during redirects (https://github.com/seanmonstar/reqwest/issues/10)
- fixes sending of the Referer to an HTTP site when coming from HTTPS, and removes username and fragment explicitly (https://github.com/seanmonstar/reqwest/commit/d8696045b4c6bc4d9e33789cff6a9e1fa75462d7)
- documentation updates

## v0.6.1

### Features

- adds `Error::get_ref` to get the underlying error that may have occurred. Includes a `'static` bounds, which allows for downcasting (as opposed to `Error::cause`).

# v0.6.0

### Features

- Upgraded to serde `1.0`
- Added a `url` [method](https://docs.rs/reqwest/0.6.0/reqwest/struct.Error.html#method.url) to `Error`, which returns a possible associated `Url` that occurred with this error.
- Added `req.basic_auth(user, optional_pass)` [method](https://docs.rs/reqwest/0.6.0/reqwest/struct.RequestBuilder.html#method.basic_auth) to ease using `Basic` authentication.

### Breaking Changes

- The publicly exposed peer dependency serde was upgraded. It is now `serde@1.0`. Mismatched version will give a compiler error that a serde trait is not implemented.
- `Error` is no longer an `enum`, but an opaque struct. Details about it can be checked with `std::error::Error::cause()`, and methods on `reqwest::Error` include `is_http()`, `is_serialization()`, and `is_redirect()`.
- `RedirectPolicy::custom` receives different arguments, and returns different values. See the [docs](https://docs.rs/reqwest/0.6.0/reqwest/struct.RedirectPolicy.html#method.custom) for an example.

## v0.5.2

### Fixes

- fix panic with Gzip decoder on an empty body (https://github.com/seanmonstar/reqwest/issues/82)

## v0.5.1

### Features

- add `Clone` implementation for `Client`

# v0.5.0

### Features

- Automatic GZIP decoding: By default, `Client` will try to decode any responses that appear to be gzip encoded (based on headers). This can be disabled via `client.gzip(false)` (https://github.com/seanmonstar/reqwest/commit/ab5e477a123319efd4b17f3666b41b44ec244bee)
- Specify a timeout for requests using `client.timeout(duration)`. (https://github.com/seanmonstar/reqwest/commit/ec049fefbae7355f6e4ddbbc7ebedcadb30e1e04)
- Request bodies with a known length can be constructed with `Body::sized()` (https://github.com/seanmonstar/reqwest/commit/82f1877d4b6cba2fac432670ec306160aee5c501)
- Add `Client.put`, `Client.patch`, and `Client.delete` convenience methods (https://github.com/seanmonstar/reqwest/commit/c37b8aa0338ac4142763d206c6df79856915056d, https://github.com/seanmonstar/reqwest/commit/4d6582d22b23c27927e481a9c8a83ad08cfd1a2a, https://github.com/seanmonstar/reqwest/commit/a3983f3122b2d1495ea36bb5a8fd019a7605ae56)
- Add `reqwest::mime` (https://github.com/seanmonstar/reqwest/commit/0615c6d65e03ba9cb5364169c9e74f4f2a91554b)

### Breaking Changes

The only breaking change is a behavioral one, all programs should still compile without modification. The automatic GZIP decoding could interfere in cases where a user was expecting the GZIP bytes, either to save to a file or decode themselves. To restore this functionality, set `client.gzip(false)`. 

# v0.4.0

- updated to serde 0.9

# v0.3.0

- updated to hyper 0.10

# v0.2.0

### Features

- add support for 307 and 308 redirects (https://github.com/seanmonstar/reqwest/commit/a54447c1d9c75dab639333265f51a91a43e99c2e)
- implement `Sync` for `Client`, and `Send` for `RequestBuilder` and `Response` (https://github.com/seanmonstar/reqwest/commit/d18a53b3fcc81c4a60875755c8e95d777a343319)
- implement `Send` for `Error` (https://github.com/seanmonstar/reqwest/commit/20b161096e67d22c962e69b2656ae9741ac73c25)
- implement `std::fmt::Debug` for all public types (https://github.com/seanmonstar/reqwest/commit/d624b0ef29020c6085ec94651a990f58ccd684e2)

### Breaking Changes
- `Error::Serialize` now has a `Box<StdError + Send + Sync>` instead of `Box<StdError>`
- `RequestBuilder` no longer has an associated lifetime (was `RequestBuilder<'a>`)

# v0.1.0
