-## Unreleased - 2020-xx-xx
-
-
-## 2.0.0-beta.1 - 2020-12-28
-* `Service`, other traits, and many type signatures now take the the request type as a type
-  parameter instead of an associated type. [#232]
-* Add `always_ready!` and `forward_ready!` macros. [#233]
-* Crate is now `no_std`. [#233]
-* Migrate pin projections to `pin-project-lite`. [#233]
-* Remove `AndThenApplyFn` and Pipeline `and_then_apply_fn`. Use the
-  `.and_then(apply_fn(...))` construction. [#233]
-* Move non-vital methods to `ServiceExt` and `ServiceFactoryExt` extension traits. [#235]

-## 1.0.6 - 2020-08-09
-
-### Fixed
-
-* Removed unsound custom Cell implementation that allowed obtaining several mutable references to
-  the same data, which is undefined behavior in Rust and could lead to violations of memory safety. External code could obtain several mutable references to the same data through
-  service combinators. Attempts to acquire several mutable references to the same data will instead
-  result in a panic.

-/// An asynchronous operation from `Request` to a `Response`.
-///
-/// The `Service` trait models a request/response interaction, receiving requests and returning
-/// replies. You can think about a service as a function with one argument that returns some result
-/// asynchronously. Conceptually, the operation looks like this:
-///
-/// ```rust,ignore
-/// async fn(Request) -> Result<Response, Err>
-/// ```
-///
-/// The `Service` trait just generalizes this form where each parameter is described as an
-/// associated type on the trait. Services can also have mutable state that influence computation.
-///
-/// `Service` provides a symmetric and uniform API; the same abstractions can be used to represent
-/// both clients and servers. Services describe only _transformation_ operations which encourage
-/// simple API surfaces. This leads to simpler design of each service, improves test-ability and
-/// makes composition easier.
-///
-/// ```rust,ignore
-/// struct MyService;
-///
-/// impl Service for MyService {
-///      type Request = u8;
-///      type Response = u64;
-///      type Error = MyError;
-///      type Future = Pin<Box<Future<Output=Result<Self::Response, Self::Error>>>>;
-///
-///      fn poll_ready(&mut self, cx: &mut Context<'_>) -> Poll<Result<(), Self::Error>> { ... }
-///
-///      fn call(&mut self, req: Self::Request) -> Self::Future { ... }
-/// }
-/// ```
-///
-/// Sometimes it is not necessary to implement the Service trait. For example, the above service
-/// could be rewritten as a simple function and passed to [fn_service](fn_service()).
-///
-/// ```rust,ignore
-/// async fn my_service(req: u8) -> Result<u64, MyError>;
-/// ```
-pub trait Service<Req> {
-    /// Responses given by the service.
-    type Response;

-///
-/// For example, timeout transform:

-///     timeout: Duration,
-/// }

-///
-/// Timeout service in above example is decoupled from underlying service implementation
-/// and could be applied to any service.
-///
-/// The `Transform` trait defines the interface of a Service factory. `Transform`
-/// is often implemented for middleware, defining how to construct a
