## v1.8.0 (2025-11-11)


#### Bug Fixes

#### Breaking Changes

* The HTTP/2 client connection no longer allows an executor
  that can not spawn itself.

  This was an oversight originally. The client connection will now include spawning
  a future that keeps a copy of the executor to spawn other futures. Thus, if it is
  `!Send`, it needs to spawn `!Send` futures. The likelihood of executors that match
  the previously allowed behavior should be very remote.

  There is also technically a semver break in here, which is that the
  `Http2ClientConnExec` trait no longer dyn-compatible, because it now expects to
  be `Clone`. This should not break usage of the `conn` builder, because it already
  separately had `E: Clone` bounds. If someone were using `dyn Http2ClientConnExec`,
  that will break. However, there is no purpose for doing so, and it is not usable
  otherwise, since the trait only exists to propagate bounds into hyper. Thus, the
  breakage should not affect anyone.

### v1.0.1 (2023-11-16)

This release "fixes" or adds a few things that should have been in 1.0.0, but were forgotten. Thus, it includes additions that would normally be a semver-minor release, but because it is so close to 1.0.0, it is released as a patch version.

#### Bug Fixes

* **rt:** implement Read/Write for Pin<P> (#3413) ([dd6d81ca](https://github.com/hyperium/hyper/commit/dd6d81ca4a180695dc70d6c9b2aececd29606224), closes [#3412](https://github.com/hyperium/hyper/issues/3412))


#### Features

* **rt:** Make ReadBuf::new public ([7161f562](https://github.com/hyperium/hyper/commit/7161f56274a30bfbe4a718bbe21d35beaf86b00b))


#### Breaking Changes

* Pin is #[fundamental], so providing a Read/Write impl for it theoretically conflicts
  with existing user Read/Write for Pin<...> impls. However, those impls
  probably don't exist yet.
 ([dd6d81ca](https://github.com/hyperium/hyper/commit/dd6d81ca4a180695dc70d6c9b2aececd29606224))

#### Breaking Changes

* Upgrade to `http` 1.0.

 ([899e92a5](https://github.com/hyperium/hyper/commit/899e92a580961c5bd1cc9b49a8fb7c7cd8b53ef8))
* (From previous RCs) `ExecutorClient` is renamed to
  `Http2ClientConnExec`, and `Http2ConnExec` is renamed to
  `Http2ServerConnExec`.

 ([52b27faa](https://github.com/hyperium/hyper/commit/52b27faa09715b5835804de7abf6998e028736fc))
* If you use client HTTP/1 upgrades, you must call
  `Connection::with_upgrades()` to still work the same.
 ([cf87eda8](https://github.com/hyperium/hyper/commit/cf87eda82ca0af1f5f45b0a0710eaae9ec1aed7b))
* HTTP/2 server builder now has a default max concurrent streams. This is a
  behavior change. Consider setting your own maximum.
 ([dd638b5b](https://github.com/hyperium/hyper/commit/dd638b5b34225d2c5ad0bd01de0ecf738f9a0e12))
* Do not build any logic depending on the exact types of
  an `Error::source()`. They are only for debugging.
 ([502a6450](https://github.com/hyperium/hyper/commit/502a645053b0d19252d9fdc170b0a2c0a6fe0ba6))
* The format no longer prints the error chain. Be sure to
  check if you are logging errors directly.

  The `Error::message()` method is removed, it is no longer needed.

  The `Error::into_cause()` method is removed.
 ([50f123af](https://github.com/hyperium/hyper/commit/50f123afc0e6c289030bf8699dbec826dc47572c))
* The `ReasonPhrase::from_bytes_unchecked()` method is

* **http1:**
  * http1 server graceful shutdown fix (#3261) ([f4b51300](https://github.com/hyperium/hyper/commit/f4b513009d81083081d1c60c1981847bbb17dd5d))

#### Breaking Changes

* Any IO transport type provided must now implement `hyper::rt::{Read, Write}` instead of
  `tokio::io` traits. You can grab a helper type from `hyper-util` to wrap Tokio types, or implement the traits yourself,
  if it's a custom type.
 ([f9f65b7a](https://github.com/hyperium/hyper/commit/f9f65b7aa67fa3ec0267fe015945973726285bc2))
* `client::conn::http2` types now use another generic for an `Executor`.
  Code that names `Connection` needs to include the additional generic parameter.
 ([d977f209](https://github.com/hyperium/hyper/commit/d977f209bc6068d8f878b22803fc42d90c887fcc))
* The Service::call function no longer takes a mutable reference to self.
  The FnMut trait bound on the service::util::service_fn function and the trait bound
  on the impl for the ServiceFn struct were changed from FnMut to Fn.

#### Breaking Changes

* hyper depends on `tokio` v1 and `bytes` v1.
* Custom resolvers used with `HttpConnector` must change
  to resolving to an iterator of `SocketAddr`s instead of `IpAddr`s.
 ([b4e24332](https://github.com/hyperium/hyper/commit/b4e24332a0cd44068a806081d51686f50c086056))
* hyper no longer emits `log` records automatically.
  If you need hyper to integrate with a `log` logger (as opposed to `tracing`),
  you can add `tracing = { version = "0.1", features = ["log"] }` to activate them.
 ([db32e105](https://github.com/hyperium/hyper/commit/db32e1050cf1eae63af0365c97e920f1295b6bea))
* Removed `http1_writev` methods from `client::Builder`,
  `client::conn::Builder`, `server::Builder`, and `server::conn::Builder`.
  
  Vectored writes are now enabled based on whether the `AsyncWrite`
  implementation in use supports them, rather than though adaptive
  detection. To explicitly disable vectored writes, users may wrap the IO
  in a newtype that implements `AsyncRead` and `AsyncWrite` and returns
  `false` from its `AsyncWrite::is_write_vectored` method.
 ([d6aadb83](https://github.com/hyperium/hyper/commit/d6aadb830072959497f414c01bcdba4c8e681088))
* The method `Body::on_upgrade()` is gone. It is
  essentially replaced with `hyper::upgrade::on(msg)`.
 ([121c3313](https://github.com/hyperium/hyper/commit/121c33132c0950aaa422848cdc43f6691ddf5785))

#### Breaking Changes

* All usage of async traits (`Future`, `Stream`,
`AsyncRead`, `AsyncWrite`, etc) are updated to newer versions.

 ([8f4b05ae](https://github.com/hyperium/hyper/commit/8f4b05ae78567dfc52236bc83d7be7b7fc3eebb0))
* All usage of `hyper::Chunk` should be replaced with
  `bytes::Bytes` (or `hyper::body::Bytes`).

 ([5a598757](https://github.com/hyperium/hyper/commit/5a59875742500672f253719c1e1a16b4eddfacc7))
* Using a `Body` as a `Stream`, and constructing one via
  `Body::wrap_stream`, require enabling the `stream` feature.

 ([511ea388](https://github.com/hyperium/hyper/commit/511ea3889b5cceccb3a42aa72465fe38adef71a4))
* Calls to `GaiResolver::new` and `HttpConnector::new` no
  longer should pass an integer argument for the number of threads.

 ([049b5132](https://github.com/hyperium/hyper/commit/049b5132dbb6199a32e1795d005003f99d0e0b74))
* Connectors no longer return a tuple of
  `(T, Connected)`, but a single `T: Connection`.

 ([4d7a2266](https://github.com/hyperium/hyper/commit/4d7a2266b88b2c5c92231bcd2bd75d5842198add))
* All usage of `hyper::client::connect::Destination`
  should be replaced with `http::Uri`.

 ([319e8aee](https://github.com/hyperium/hyper/commit/319e8aee1571d8d3639b3259e7a1edb964e6a26c))
* All usage of `hyper::body::Payload` should be replaced
  with `hyper::body::HttpBody`.

 ([c63728eb](https://github.com/hyperium/hyper/commit/c63728eb38182ad2f93edd729dbf50f3d5c40479))
* Any type passed to the `executor` builder methods must
  now implement `hyper::rt::Executor`.

  `hyper::rt::spawn` usage should be replaced with `tokio::task::spawn`.

  `hyper::rt::run` usage should be replaced with `#[tokio::main]` or
  managing a `tokio::runtime::Runtime` manually.

 ([6ae5889f](https://github.com/hyperium/hyper/commit/6ae5889f8378b6454d4dc620f33bd1678d0e00e4))
* The `Resolve` trait is gone. All custom resolvers should
  implement `tower::Service` instead.

  The error type of `HttpConnector` has been changed away from
  `std::io::Error`.

 ([9d9233ce](https://github.com/hyperium/hyper/commit/9d9233ce7ceddb0fa6f5e725b0a781929add3c58))
* Any manual implementations of `Connect` must instead
  implement `tower::Service<Uri>`.

 ([d67e49f1](https://github.com/hyperium/hyper/commit/d67e49f1491327a78f804bab32804dc6c73d2974))
* The server's behavior will now by default close
  connections when receiving a read EOF. To allow for clients to close
  the read half, call `http1_half_close(true)` when configuring a
  server.

 ([7e31fd88](https://github.com/hyperium/hyper/commit/7e31fd88a86ac032d05670ba4e293e3e5fcccbaf))
* Passing a `Stream` to `Server::builder` or
  `Http::serve_incoming` must be changed to pass an `Accept` instead. The
  `stream` optional feature can be enabled, and then a stream can be
  converted using `hyper::server::accept::from_stream`.

 ([b3e55062](https://github.com/hyperium/hyper/commit/b3e5506261c33dcaca39a126e891a0b9d5df5eea))
* Usage of `send_data` should either be changed to
  async/await or use `try_send_data`.

#### Bug Fixes

* **lib:** remove deprecated tokio-proto APIs ([a37e6b59](https://github.com/hyperium/hyper/commit/a37e6b59e6d6936ee31c6d52939869933c709c78))
* **server:** panic on max_buf_size too small ([aac250f2](https://github.com/hyperium/hyper/commit/aac250f29d3b05d8c07681a407825811ec6a0b56))

#### Breaking Changes

* `Body::is_empty()` is gone. Replace with
  `Body::is_end_stream()`, from the `Payload` trait.

  ([19f90242](https://github.com/hyperium/hyper/commit/19f90242f8a3768b2d8d4bff4044a2d6c77d40aa))
* Each payload chunk must implement `Buf`, instead of
  just `AsRef<[u8]>`.

  ([a3be110a](https://github.com/hyperium/hyper/commit/a3be110a55571a1ee9a31b2335d7aec27c04e96a))
* Replace any references of
  `hyper::client::FutureResponse` to `hyper::client::ResponseFuture`.

  ([04c74ef5](https://github.com/hyperium/hyper/commit/04c74ef596eb313b785ecad6c42c0375ddbb1e96))
* The `Service` trait has changed: it has some changed
  associated types, and `call` is now bound to `&mut self`.

  The `NewService` trait has changed: it has some changed associated
  types, and `new_service` now returns a `Future`.

  `Client` no longer implements `Service` for now.

  `hyper::server::conn::Serve` now returns `Connecting` instead of
  `Connection`s, since `new_service` can now return a `Future`. The
  `Connecting` is a future wrapping the new service future, returning
  a `Connection` afterwards. In many cases, `Future::flatten` can be
  used.

  ([2dc6202f](https://github.com/hyperium/hyper/commit/2dc6202fe7294fa74cf1ba58a45e48b8a927934f))
* The `Server` is no longer created from `Http::bind`,
  nor is it `run`. It is a `Future` that must be polled by an
  `Executor`.

  The `hyper::server::Http` type has move to
  `hyper::server::conn::Http`.

  ([c4974500](https://github.com/hyperium/hyper/commit/c4974500abee45b95b0b54109cad15978ef8ced9))
* `Client:new(&handle)` and `Client::configure()` are now
  `Client::new()` and `Client::builder()`.

  ([fe1578ac](https://github.com/hyperium/hyper/commit/fe1578acf628844d7cccb3e896c5e0bb2a0be729))
* `Error` is no longer an enum to pattern match over, or
  to construct. Code will need to be updated accordingly.

  For body streams or `Service`s, inference might be unable to determine
  what error type you mean to return.

  ([5d3c4722](https://github.com/hyperium/hyper/commit/5d3c472228d40b57e47ea26004b3710cfdd451f3))
* All uses of `Handle` now need to be new-tokio `Handle`.

  ([27b8db3a](https://github.com/hyperium/hyper/commit/27b8db3af8852ba8280a2868f703d3230a1db85e))
* Custom connectors should now implement `Connect`
  directly, instead of `Service`.

  Calls to `connect` no longer take `Uri`s, but `Destination`. There
  are `scheme`, `host`, and `port` methods to query relevant
  information.

  The returned future must be a tuple of the transport and `Connected`.
  If no relevant extra information is needed, simply return
  `Connected::new()`.

  ([8c52c2df](https://github.com/hyperium/hyper/commit/8c52c2dfd342e798420a0b83cde7d54f3af5e351))
* All code that was generic over the body as `Stream` must
  be adjusted to use a `Payload` instead.

  `hyper::Body` can still be used as a `Stream`.

  Passing a custom `impl Stream` will need to either implement
  `Payload`, or as an easier option, switch to `Body::wrap_stream`.

  `Body::pair` has been replaced with `Body::channel`, which returns a
  `hyper::body::Sender` instead of a `futures::sync::mpsc::Sender`.

  ([fbc449e4](https://github.com/hyperium/hyper/commit/fbc449e49cc4a4f8319647dccfb288d3d83df2bd))
* `Method`, `Request`, `Response`, `StatusCode`,
  `Version`, and `Uri` have been replaced with types from the `http`
  crate.

  ([3cd48b45](https://github.com/hyperium/hyper/commit/3cd48b45fb622fb9e69ba773e7f92b9d3e9ac018))
  * The variants of `Method` are now uppercase, for instance, `Method::Get` is now `Method::GET`.
  * The variants of `StatusCode` are now uppercase, for instance, `StatusCode::Ok` is now `StatusCode::OK`.
  * The variants of `Version` are now uppercase, for instance, `HttpVersion::Http11` is now `Version::HTTP_11`.
*  The typed headers from `hyper::header` are gone for now.

  The `http::header` module is re-exported as `hyper::header`.

  For example, a before setting the content-length:

  ```rust
  use hyper::header::ContentLength;
  res.headers_mut().set(ContentLength(15));
  ```

  And now **after**, with the `http` types:

  ```rust
  use hyper::header::{CONTENT_LENGTH, HeaderValue};
  res.headers_mut().insert(CONTENT_LENGTH, HeaderValue::from_static("15"));
  ```

  ([3cd48b45](https://github.com/hyperium/hyper/commit/3cd48b45fb622fb9e69ba773e7f92b9d3e9ac018))
* The `mime` crate is no longer re-exported as `hyper::mime`.

  The typed headers don't exist, and so they do not need the `mime` crate.

  To continue using `mime` for other purposes, add it directly to your `Cargo.toml`
  as a dependency.

  ([3cd48b45](https://github.com/hyperium/hyper/commit/3cd48b45fb622fb9e69ba773e7f92b9d3e9ac018))
* Removed `compat` cargo feature, and `compat` related API. This was the conversion methods for hyper's
  types to and from `http` crate's types.

  ([3cd48b45](https://github.com/hyperium/hyper/commit/3cd48b45fb622fb9e69ba773e7f92b9d3e9ac018))
* Removed deprecated APIs:
  ([a37e6b59](https://github.com/hyperium/hyper/commit/a37e6b59e6d6936ee31c6d52939869933c709c78))
  * The `server-proto` cargo feature, which included `impl ServerProto for Http`, and related associated types.
  * `client::Config::no_proto()`
  * `tokio_proto::streaming::Body::from(hyper::Body)`
  * `hyper::Body::from(tokio_proto::streaming::Body)`
  * `hyper::Body::from(futures::sync::mpsc::Receiver)`
  * `Http::no_proto()`

  * switch to non-blocking (asynchronous) IO ([d35992d0](https://github.com/hyperium/hyper/commit/d35992d0198d733c251e133ecc35f2bca8540d96))
* **mime:** upgrade to mime v0.3 ([f273224f](https://github.com/hyperium/hyper/commit/f273224f21eedd2f466f12fe30fd24e83c35922c), closes [#738](https://github.com/hyperium/hyper/issues/738))
* **server:**
  * make Http default its body type to hyper::Chunk ([dc97dd77](https://github.com/hyperium/hyper/commit/dc97dd77f45486d9cb9a22a1859809c5af5579e2))
  * make Http compatible with TcpServer ([e04bcc12](https://github.com/hyperium/hyper/commit/e04bcc12a7e081f75482cdca1e4f4c4f597ad2ce), closes [#1036](https://github.com/hyperium/hyper/issues/1036))
  * add path() and query() to Request ([8b3c1206](https://github.com/hyperium/hyper/commit/8b3c1206846cb96be780923952eafe0dde7850bf), closes [#896](https://github.com/hyperium/hyper/issues/896), [#897](https://github.com/hyperium/hyper/issues/897))
* **status:**
  * add `StatusCode::try_from(u16)`. ([f953cafe](https://github.com/hyperium/hyper/commit/f953cafe27d1c5de0c8b859e485225cfc2c18629))
  * remove deprecated `StatusClass` ([94ee6204](https://github.com/hyperium/hyper/commit/94ee6204ae32b8c431c00fdc03dc75eee573c69c))
  * impl Into<u16> for StatusCode ([c42f18db](https://github.com/hyperium/hyper/commit/c42f18db05e47fc24e8a8ece76cbc782b7558e8b))
* **uri:**
  * redesign `RequestUri` type into `Uri` ([9036443e](https://github.com/hyperium/hyper/commit/9036443e6bd61b948ebe622588d2765e22e2b179), closes [#1000](https://github.com/hyperium/hyper/issues/1000))
  * add `is_absolute` method to `Uri` ([154ab29c](https://github.com/hyperium/hyper/commit/154ab29c0d2b50d7bcac0f7918abf2f7a1628112))
* **version:** impl `FromStr` for `HttpVersion` ([47f3aa62](https://github.com/hyperium/hyper/commit/47f3aa6247a3211ae499b30584dca6acb43d2204))


#### Breaking Changes

* The `Cookie` header is no longer a wrapper over a
  `Vec<String>`. It must be accessed via its `get` and `set` methods.

 ([dd03e723](https://github.com/hyperium/hyper/commit/dd03e7239238e6c0753cf2502a0534e2c9770d9e))
* Any use of `Quality(num)` should change to `q(num)`.

 ([a4644959](https://github.com/hyperium/hyper/commit/a4644959b0f980d94898d6c2e3cb1763aac73a5e))
* `HttpDate` no longer has public fields. Convert between
  `HttpDate` and `SystemTime` as needed.

 ([316c6fad](https://github.com/hyperium/hyper/commit/316c6fad3026ba5ff5f6b9f31aca4d4f74b144e0))
* The `link_extensions` methods of the `Link` header are
  removed until fixed.

 ([011f28cb](https://github.com/hyperium/hyper/commit/011f28cb18d285401bc8bea2b0f0dbdf80089d97))
* The `fmt_header` method has changed to take a different
  formatter. In most cases, if your header also implements
  `fmt::Display`, you can just call `f.fmt_line(self)`.

 ([6f02d43a](https://github.com/hyperium/hyper/commit/6f02d43ae0d80971a32617e316498b81acf38ca2))
* The `Encoding` enum has an additional variant, `Trailers`.

 ([f1859dfd](https://github.com/hyperium/hyper/commit/f1859dfd7abfc124dd986edc413f754f76c76e8b))
* `Origin.scheme` and `Origin.host` now return `Option`s, since the `Origin` could be `null`.

 ([41485997](https://github.com/hyperium/hyper/commit/414859978b47dc8ebd0df264afc4e113b8a1909e))
* If you were explicitly checking the `StatusCode`, such as
  with an equality comparison, you will need to use the value instead of a
  reference.

 ([d63b7de4](https://github.com/hyperium/hyper/commit/d63b7de44f813696f8ec595d2f8f901526c1720e))
* This removes several deprecated methods for converting
  Headers into strings. Use more specialized methods instead.

 ([ec91bf41](https://github.com/hyperium/hyper/commit/ec91bf418b1f285bac9231d4bee0dd96742e565a))
* The `Url` type is no longer used. Any instance in the
  `Client` API has had it replaced with `hyper::Uri`.

  This also means `Error::Uri` has changed types to
  `hyper::error::UriError`.

  The type `hyper::header::parsing::HTTP_VALUE` has been made private,
  as an implementation detail. The function `http_percent_encoding`
  should be used instead.

 ([4fb7e6eb](https://github.com/hyperium/hyper/commit/4fb7e6ebc6b1d429dcce4bc18139bd443fffa6ee))
* This makes `Request.remote_addr` an
  `Option<SocketAddr>`, instead of `SocketAddr`.

 ([e04bcc12](https://github.com/hyperium/hyper/commit/e04bcc12a7e081f75482cdca1e4f4c4f597ad2ce))
* The `Preference` header had a typo in a variant and it's string representation,
  change `Preference::HandlingLeniant` to `Preference::HandlingLenient`.
 ([2fa414fb](https://github.com/hyperium/hyper/commit/2fa414fb5fe6dbc922da25cca9960652edf32591))
* `Server` is no longer the primary entry point. Instead,
  an `Http` type is created  and then either `bind` to receive a `Server`,
  or it can be passed to other Tokio things.
 ([f45e9c8e](https://github.com/hyperium/hyper/commit/f45e9c8e4fcacc2bd7fed84ef0df6d2fcf8c1134))
* The name of `RequestUri` has changed to `Uri`. It is no
  longer an `enum`, but an opaque struct with getter methods.

 ([9036443e](https://github.com/hyperium/hyper/commit/9036443e6bd61b948ebe622588d2765e22e2b179))
* This adds a new variant to the `Encoding` enum, which
  can break exhaustive matches.

 ([f0ab2b6a](https://github.com/hyperium/hyper/commit/f0ab2b6aedb909d37698365d1fcc34ce749304b5))
* The fields of the `Host` header are no longer
  available. Use the getter methods instead.

 ([cd9fd522](https://github.com/hyperium/hyper/commit/cd9fd522074bfe530c30c878e49e6ac1bd881f1f))
* A big sweeping set of breaking changes.

 ([2d2d5574](https://github.com/hyperium/hyper/commit/2d2d5574a698e74e5102d39b9a9ab750860d92d1))
* `Headers.remove()` used to return a `bool`,
  it now returns `Option<H>`. To determine if a a header exists,
  switch to `Headers.has()`.
 ([9375addb](https://github.com/hyperium/hyper/commit/9375addba03505f2515d493364f9b1beb8b9b99a))
* `Header::parse_header` now receives `&Raw`, instead of
  a `&[Vec<u8>]`. `Raw` provides several methods to ease using it, but
  may require some changes to existing code.
 ([50ccdaa7](https://github.com/hyperium/hyper/commit/50ccdaa7e7db574ec9890c220765ffd2da5e493b))
* LanguageTag used to be at the crate root, but it is now
  in the `hyper::header` module.

 ([40745c56](https://github.com/hyperium/hyper/commit/40745c5671daf8ac7eb342ff0e1e7c801a7171c4))
* Removes the undocumented `from_u16` function. Use
  `StatusCode::try_from` instead.

  Also makes the `status` module private. All imports of
  `hyper::status::StatusCode` should be `hyper::StatusCode`.

 ([f953cafe](https://github.com/hyperium/hyper/commit/f953cafe27d1c5de0c8b859e485225cfc2c18629))
* All usage of `status.class()` should change to
  equivalent `status.is_*()` methods.

 ([94ee6204](https://github.com/hyperium/hyper/commit/94ee6204ae32b8c431c00fdc03dc75eee573c69c))
* Most uses of `mime` will likely break. There is no more
  `mime!` macro, nor a `Mime` constructor, nor `TopLevel` and `SubLevel`
  enums.

  Instead, in most cases, a constant exists that can now be used.

  For less common mime types, they can be created by parsing a string.

 ([f273224f](https://github.com/hyperium/hyper/commit/f273224f21eedd2f466f12fe30fd24e83c35922c))
* To use `RawStatus`, you must enable the `raw_status`
  crate feature.

 ([acd62cda](https://github.com/hyperium/hyper/commit/acd62cda446e4c647716a2d595342360dc24a080))
* Some headers used `UniCase`, but now use
  `unicase::Ascii`. Upgrade code to `Ascii::new(s)`.

 ([c81edd41](https://github.com/hyperium/hyper/commit/c81edd41d783f67eca7a50d83b40c8a7cedf333c))
* This breaks a lot of the Client and Server APIs.
  Check the documentation for how Handlers can be used for asynchronous
  events.

 ([d35992d0](https://github.com/hyperium/hyper/commit/d35992d0198d733c251e133ecc35f2bca8540d96))

  * introduce Response::get_ref ([5ef0ec2c](https://github.com/hyperium/hyper/commit/5ef0ec2cd2841e78508a61949a207187be914265))


### v0.10.7 (2017-04-08)


#### Bug Fixes

* **server:** don't dup the listener TCP socket. ([d2362331](https://github.com/hyperium/hyper/commit/d23623317820696c910ce43262d5276e8e24c066))


### v0.10.6 (2017-04-05)


#### Features

* **buffer:** add from_parts and into_parts functions ([78551dd0](https://github.com/hyperium/hyper/commit/78551dd040e2ab46e833af355c92fe87aa026244))


### v0.10.5 (2017-03-01)


#### Bug Fixes

* **http:**
  * Consume entire chunked encoding message ([4147fcd0](https://github.com/hyperium/hyper/commit/4147fcd0d688b6d5b8d6b32f26c147819321a390))
  * fix returning EarlyEof if supplied buffer is zero-len ([1e740fbc](https://github.com/hyperium/hyper/commit/1e740fbcc3fb60af2fe8d2227457fa29582151c3))


### v0.10.4 (2017-01-31)


#### Features

* **header:** implement fmt::Display for several headers ([d5075770](https://github.com/hyperium/hyper/commit/d50757707b1c628f398fb0583aa3dd02111ae658))


### v0.10.3 (2017-01-30)


#### Bug Fixes

* **header:**
  * deprecate HeaderFormatter ([282466e1](https://github.com/hyperium/hyper/commit/282466e1c00879cf9dde1ed62c3d436e99bfba85))
  * enable SetCookie.fmt_header when only 1 cookie ([7611c307](https://github.com/hyperium/hyper/commit/7611c3071475afa2b0b80bbba2a0a7223a3d5920))


#### Features

* **header:** add Headers::append_raw ([6babbc40](https://github.com/hyperium/hyper/commit/6babbc40fb86a29ad76083a2a386182c40c0f335))


### v0.10.2 (2017-01-23)


#### Bug Fixes

* **header:** security fix for header values that include newlines ([2603d78f](https://github.com/hyperium/hyper/commit/2603d78f59d284953553b7ef48c3ea4baa085cd1))
* **net:** set timeouts directly in `accept` ([f5d4d653](https://github.com/hyperium/hyper/commit/f5d4d653e35ed20bbbb0b13847b3b9f1cfe9575f))


#### Breaking Changes

* This technically will cause code that a calls
  `SetCookie.fmt_header` to panic, as it is no longer to properly write
  that method. Most people should not be doing this at all, and all
  other ways of printing headers should work just fine.

  The breaking change must occur in a patch version because of the
  security nature of the fix.

 ([2603d78f](https://github.com/hyperium/hyper/commit/2603d78f59d284953553b7ef48c3ea4baa085cd1))


### v0.10.1 (2017-01-19)


## v0.10.0 (2017-01-10)

#### Features

* **client:**
  * change ProxyConfig to allow HTTPS proxies ([14a4f1c2](https://github.com/hyperium/hyper/commit/14a4f1c2f735efe7b638e9078710ca32dc1e360a))
  * remove experimental HTTP2 support ([d301c6a1](https://github.com/hyperium/hyper/commit/d301c6a1708c7d408b7f03ac46674a5f0edd3253))
* **header:** remove `cookie` dependency ([f22701f7](https://github.com/hyperium/hyper/commit/f22701f7e7258ad4a26645eba47a3d374e452e86))
* **lib:**
  * remove SSL dependencies ([2f48612c](https://github.com/hyperium/hyper/commit/2f48612c7e141a9d612d7cb9d524b2f460561f56))
  * remove `serde-serialization` feature ([7b9817ed](https://github.com/hyperium/hyper/commit/7b9817edcf4451bd033e55467c75577031bfe740))


#### Breaking Changes

* There is no more `hyper::http::h2`.

  ([d301c6a1](https://github.com/hyperium/hyper/commit/d301c6a1708c7d408b7f03ac46674a5f0edd3253))
* The `Cookie` and `SetCookie` headers no longer use the
  cookie crate. New headers can be written for any header, or the ones
  provided in hyper can be accessed as strings.

  ([f22701f7](https://github.com/hyperium/hyper/commit/f22701f7e7258ad4a26645eba47a3d374e452e86))
* There is no longer a `serde-serialization` feature.
  Look at external crates, like `hyper-serde`, to fulfill this feature.

  ([7b9817ed](https://github.com/hyperium/hyper/commit/7b9817edcf4451bd033e55467c75577031bfe740))
* hyper will no longer provide OpenSSL support out of the
  box. The `hyper::net::Openssl` and related types are gone. The `Client`
  now uses an `HttpConnector` by default, which will error trying to
  access HTTPS URLs.

  TLS support should be added in from other crates, such as
  hyper-openssl, or similar using different TLS implementations.

  ([2f48612c](https://github.com/hyperium/hyper/commit/2f48612c7e141a9d612d7cb9d524b2f460561f56))
* Usage of `with_proxy_config` will need to change to
  provide a network connector. For the same functionality, a
  `hyper::net::HttpConnector` can be easily created and passed.

  ([14a4f1c2](https://github.com/hyperium/hyper/commit/14a4f1c2f735efe7b638e9078710ca32dc1e360a))

* mime 0.2 depends on serde 0.7, so any instances of
  using older versions of serde will need to upgrade.

 ([146df53c](https://github.com/hyperium/hyper/commit/146df53caf2a70cd15f97710738ba8d350040c12))

## v0.7.0 (2015-11-24)


#### Features

* **all:** add socket timeouts ([fec6e3e8](https://github.com/hyperium/hyper/commit/fec6e3e873eb79bd17d1c072d2ca3c7b91624f9c))

#### Breaking Changes

* This adds 2 required methods to the `NetworkStream`
  trait, `set_read_timeout` and `set_write_timeout`. Any local
  implementations will need to add them.

 ([fec6e3e8](https://github.com/hyperium/hyper/commit/fec6e3e873eb79bd17d1c072d2ca3c7b91624f9c))
* LanguageTags api is changed.

 ([c747f99d](https://github.com/hyperium/hyper/commit/c747f99d2137e03b5f4393ee3731f6ebeab9ee6e))

 ([ff4a6070](https://github.com/hyperium/hyper/commit/ff4a6070573955d1623d51a3d5302a17eed8f8d6))


### v0.6.15 (2015-10-09)


#### Bug Fixes

* **server:** use a timeout for Server keep-alive ([cdaa2547](https://github.com/hyperium/hyper/commit/cdaa2547ed18dfb0e3b8ed2ca15cfda1f98fa9fc), closes [#368](https://github.com/hyperium/hyper/issues/368))

* **http:**
  * Add a stream enum that makes it impossible to lose a stream ([be4e7181](https://github.com/hyperium/hyper/commit/be4e7181456844180963d0e5234656c319ce92a6))
  * Make sure not to lose the stream when CL is invalid ([a36e44af](https://github.com/hyperium/hyper/commit/a36e44af7d4e665a122c1498011ff10035f7376f))
* **server:** use EmptyWriter for status codes that have no body ([9b2998bd](https://github.com/hyperium/hyper/commit/9b2998bddc3c033e4fc4e6a9b7d18504339ded3f))
* **timeouts:** remove rust #![feature] for socket timeouts ([b8729698](https://github.com/hyperium/hyper/commit/b872969880be502b681def26d6b9780cc90ac74b))


#### Features

* **headers:** add PartialEq impl for Headers struct ([76cbf384](https://github.com/hyperium/hyper/commit/76cbf384231e602d888e49932bf9c4fafdd88051))


### v0.6.13 (2015-09-02)


#### Bug Fixes

* **client:** EofReader by nature means the connection is closed ([32e09a04](https://github.com/hyperium/hyper/commit/32e09a04292b0247456a8fb9003a75a6abaa998e))


### v0.6.12 (2015-09-01)


#### Bug Fixes

* **client:** be resilient to invalid response bodies ([75c71170](https://github.com/hyperium/hyper/commit/75c71170206db3119d9b298ea5cf3ee860803124), closes [#640](https://github.com/hyperium/hyper/issues/640))
* **examples:** "cargo test --features serde-serialization" ([63608c49](https://github.com/hyperium/hyper/commit/63608c49c0168634238a119eb64ea1074df1b7e6))
* **http:** fix several cases in HttpReader ([5c7195ab](https://github.com/hyperium/hyper/commit/5c7195ab4a213bf0016f2185a63a6341e4cef4de))


#### Features

* **server:** Add Handler per-connection hooks ([6b6182e8](https://github.com/hyperium/hyper/commit/6b6182e8c4c81f634becebe7b45dc21bff59a286))


### v0.6.11 (2015-08-27)


#### Bug Fixes

* **client:** fix panics when some errors occurred inside HttpMessage ([ef15257b](https://github.com/hyperium/hyper/commit/ef15257b733d40bc3a7c598f61918f91385585f9))
* **headers:** case insensitive values for Connection header ([341f8eae](https://github.com/hyperium/hyper/commit/341f8eae6eb33e2242be09541807cdad9afc732e), closes [#635](https://github.com/hyperium/hyper/issues/635))


#### Breaking Changes

* This changes the signature of HttpWriter.end(),
  returning a `EndError` that is similar to std::io::IntoInnerError,
  allowing HttpMessage to retrieve the broken connections and not panic.

  The breaking change isn't exposed in any usage of the `Client` API,
  but for anyone using `HttpWriter` directly, since this was technically
  a public method, that change is breaking.

 ([ef15257b](https://github.com/hyperium/hyper/commit/ef15257b733d40bc3a7c598f61918f91385585f9))


### v0.6.10 (2015-08-19)

* **net:** impl downcast methods for NetworkStream (without + Send) ([1a91835a](https://github.com/hyperium/hyper/commit/1a91835abaa804aabf2e9bb45e9ab087274b8a18), closes [#521](https://github.com/hyperium/hyper/issues/521))
* **server:** add Request.ssl() to get underlying ssl stream ([7909829f](https://github.com/hyperium/hyper/commit/7909829f98bd9a2f454430f89b6143b977aedb35), closes [#627](https://github.com/hyperium/hyper/issues/627))

### v0.6.7 (2015-08-03)


#### Bug Fixes

#### Features

* **net:**
  * Implement NetworkConnector for closure to be more flexible ([abdd4c5d](https://github.com/hyperium/hyper/commit/abdd4c5d632059ebef9bbee95032c9500620212e))
  * add socket timeouts to Server and Client ([7d1f154c](https://github.com/hyperium/hyper/commit/7d1f154cb7b4db4a029b52857c377000a3f23419), closes [#315](https://github.com/hyperium/hyper/issues/315))


#### Breaking Changes

* Any custom implementation of NetworkStream must now
  implement `set_read_timeout` and `set_write_timeout`, so those will
  break. Most users who only use the provided streams should work with
  no changes needed.

Closes #315

 ([7d1f154c](https://github.com/hyperium/hyper/commit/7d1f154cb7b4db4a029b52857c377000a3f23419))

### v0.6.2 (2015-07-06)


#### Bug Fixes

* **http:** no longer keep alive for Http1.0 if no Connection header ([ddecb262](https://github.com/hyperium/hyper/commit/ddecb262b39b90e594a95ba16c4dc8085930677e), closes [#596](https://github.com/hyperium/hyper/issues/596))


#### Features

* **client:** add url property Response ([82ed9092](https://github.com/hyperium/hyper/commit/82ed9092e30385de004912582a7838e037497c82))

#### Breaking Changes

* Access-Control-Allow-Origin does no longer use Url

 ([ed458628](https://github.com/hyperium/hyper/commit/ed458628e54bd241b45f50fb0cf55a84ffb12205))
* Technically a break, since `Response::new()` takes an
  additional argument. In practice, the only place that should have been
  creating Responses directly is inside the Client, so it shouldn't
  break anyone. If you were creating Responses manually, you'll need to
  pass a Url argument.

 ([82ed9092](https://github.com/hyperium/hyper/commit/82ed9092e30385de004912582a7838e037497c82))

#### Breaking Changes

* AcceptLanguage and ContentLanguage use LanguageTag now,
Language removed from Hyper.

 ([99ff7e62](https://github.com/hyperium/hyper/commit/99ff7e62573865a1fc431db26b6a18c43b9127de))
* Server::https was changed to allow any implementation
  of Ssl. Server in general was also changed. HttpConnector no longer
  uses SSL; using HttpsConnector instead.

 ([53bba6eb](https://github.com/hyperium/hyper/commit/53bba6eb7f34e61e5c8a835281d625436532de8f))
* Connectors and Protocols passed to the `Client` must
  now also have a `Sync` bounds, but this shouldn't break default usage.

 ([64e47b4b](https://github.com/hyperium/hyper/commit/64e47b4bbd0433065a059804adeb2b4a2d72f327))
* parse_header returns Result instead of Option, related
code did also change

 ([195a89fa](https://github.com/hyperium/hyper/commit/195a89fa918a83c9dcab47a4b09edb464d4e8006))
* Adds a new variant to public Error enum. The proper fix
  is to stop matching exhaustively on `hyper::Error`.

 ([7c0421e3](https://github.com/hyperium/hyper/commit/7c0421e3fc1d5a8b4868b57acca87abd685f3430))
* A new variant `Http2` added to a public enum
`hyper::Error`.

 ([48e9ca2f](https://github.com/hyperium/hyper/commit/48e9ca2f70f6c6475f1579ae9212af7b4ca87e88))
* `hyper::client::request::Response` is no longer generic

parameter at all.

#### Features

* **header:**
  * add ContentType::json(), plaintext(), html(), jpeg(), and png() constructors ([b6114ecd](https://github.com/hyperium/hyper/commit/b6114ecd2e65bd59e79a67a45913adaf0f1552f0))

#### Breaking Changes

* Usage of Response.deconstruct() and construct() now use
  a &mut Headers, instead of the struct proper.

 ([49b5b8fd](https://github.com/hyperium/hyper/commit/49b5b8fdfe256ead8f3aa3d489bc4b299c190a9a))
* If you use deref! from the header module, you'll need
  to switch to using __hyper__deref!.

 ([62d96adc](https://github.com/hyperium/hyper/commit/62d96adc6b852b3836b47fc2e154bbdbab9ad7f6))
* Any custom Connectors will need to change to &self in
  the connect method. Any Connectors that needed the mutability need to
  figure out a synchronization strategy.

  Request::with_connector() takes a &NetworkConnector instead of &mut.
  Any uses of with_connector will need to change to passing &C.

 ([1b318724](https://github.com/hyperium/hyper/commit/1b318724a5fd425366daddf15c5964d7c3cbc240))

#### Breaking Changes

* Adds a variant to `hyper::Error`, which may break any
exhaustive matches.

 ([972b3a38](https://github.com/hyperium/hyper/commit/972b3a388ac3af98ba038927c551b92be3a68d62))
* The terms `Http` and `Error` have been removed from the Error
  type and its variants. `HttpError` should now be accessed as `hyper::Error`,
  and variants like `HttpIoError` should be accessed as `Error::Io`.

### v0.3.16 (2015-05-01)


#### Bug Fixes

* **header:**
  * make test_module of header! optional ([a5ce9c59](https://github.com/hyperium/hyper/commit/a5ce9c59fa61410551b07252364564a2bb13bb86), closes [#490](https://github.com/hyperium/hyper/issues/490))

#### Bug Fixes

* **headers:**
  * Do not parse empty values in list headers. ([093a29ba](https://github.com/hyperium/hyper/commit/093a29bab7eb27e78bb10506478ac486e8d61671))
  * Fix formatting of 0 qualites and formatting of empty list header fields. ([621ef521](https://github.com/hyperium/hyper/commit/621ef521f6723ba2d59beff05ff39ae8fd6df2c3))


#### Features

* **client:**
  * remove Clone requirement for NetworkStream in Client ([60d92c29](https://github.com/hyperium/hyper/commit/60d92c296a445b352679919c03c5ed2a2a297e16))

#### Breaking Changes

* This removes the trait `IntoBody`, and instead using
  `Into<Body>`, as it's more idiomatic. This will only have broken code
  that had custom implementations of `IntoBody`, and can be fixed by
  changing them to `Into<Body>`.

### v0.3.11 (2015-04-15)


#### Bug Fixes

* **headers:** Content-Encoding needs a hyphen. ([ca2815ef](https://github.com/hyperium/hyper/commit/ca2815effda2a5b27f781b7bc35105aa81121bae))


#### Features

* **client:** remove generic parameter for Connector ([139a51f1](https://github.com/hyperium/hyper/commit/139a51f1c31b80cdddf643e984bbbfbb3d3e8c96), closes [#379](https://github.com/hyperium/hyper/issues/379))


#### Breaking Changes

* `AccessControlAllowHeaders` and `AccessControlRequestHeaders` values
are case insensitive now. `AccessControlAllowOrigin` variants are now `Any` and
`Value` to match the other headers.

 ([94f38950](https://github.com/hyperium/hyper/commit/94f38950ddf9a97fdc4f44e42aada4ed8f4d9b43))
* `If-Match`, `If-None-Match` and `Vary` item variant name changed to `Items`

 ([38d297b1](https://github.com/hyperium/hyper/commit/38d297b16e5d14d533947988f770f03b49d47a17))
* `Etag` header field is now `ETag` header field

 ([4434ea6a](https://github.com/hyperium/hyper/commit/4434ea6a7d57d367c0a541c82f6289ffbda5fb6c))
* For people using the default HttpConnector and Client,
    everything should continue to just work. If the Client has been
    used with a generic parameter, it should be removed.

    However, there were some breaking changes to the internals of
    NetworkConnectors. Specifically, they no longer return a
    NetworkStream, but instead a Into<Box<NetworkStream + Send>>. All
    implementations of NetworkStream should continue to just work,
    however.

    Possible breakages could come from the stricter usage of Send
    throughout the Client API.

#### Breaking Changes

* added requirement that all HeaderFormat implementations
  must also be fmt::Debug. This likely as easy as slapping
  #[derive(Debug)] on to any custom headers.

 ([df756871](https://github.com/hyperium/hyper/commit/df756871edf4143135644c211106c5a8f8f5adb0))
* Check the docs. Everything was touched.
