-## 0.2.1 - 2018-01-18
+## 4.2.0-wip
+
+- Require Dart 3.8.
+- Export a protobuf generated symbol (`Any`)
+- Dart format all files for the new 3.8 formatter.
+- Require package:googleapis_auth
+- Require package:http 1.4.0
+- Require package:lints 6.0.0
+- Require package:protobuf 4.1.0
+- Simplify hierarchy of `ResponseFuture` (no longer have a private class in the
+  type hierarchy)
+
+## 4.1.0
+
+* Add a `serverInterceptors` argument to `ConnectionServer`. These interceptors
+  are acting as middleware, wrapping a `ServiceMethod` invocation.
+* Make sure that `CallOptions.mergeWith` is symmetric: given `WebCallOptions`
+  it should return `WebCallOptions`.
+
+## 4.0.4
+
+* Allow the latest `package:googleapis_auth`.
+
+## 4.0.3
+
+* Widen `package:protobuf` constraint to allow version 4.0.0.
+
+## 4.0.2
+
+* Internal optimization to client code.
+* Small fixes, such as ports in testing and enabling `timeline_test.dart`.
+* When the keep alive manager runs into a timeout, it will finish the transport
+  instead of closing the connection, as defined in the gRPC spec.
+* Upgrade to `package:lints` version 5.0.0 and Dart SDK version 3.5.0.
+* Upgrade `example/grpc-web` code.
+* Update xhr transport to migrate off legacy JS/HTML apis.
+* Use `package:web` to get `HttpStatus`.
+* Fix `package:web` deprecations.
+
+## 4.0.1
+
+* Fix header and trailing not completing if the call is terminated. Fixes [#727](https://github.com/grpc/grpc-dart/issues/727)
+
+## 4.0.0
+
+* Set compressed flag correctly for grpc-encoding = identity. Fixes [#669](https://github.com/grpc/grpc-dart/issues/669) (https://github.com/grpc/grpc-dart/pull/693)
+* Remove generated status codes.
+* Remove dependency on `package:archive`.
+* Move `codec.dart`.
+* Work around hang during Flutter hot restart by adding default case handler in _GrpcWebConversionSink.add.
+
+## 3.2.4
+
+* Forward internal `GrpcError` on when throwing while sending a request.
+* Add support for proxies, see [#33](https://github.com/grpc/grpc-dart/issues/33).
+* Remove canceled `ServerHandler`s from tracking list.
+* Fix regression on fetching the remote address of a closed socket.
+
+## 3.2.3
+
+* Add const constructor to `GrpcError` fixing #606.
+* Make `GrpcError` non-final to allow implementations.
+* Only send keepalive pings on open connections.
+* Fix interop tests.
+
+## 3.2.2
+
+* Remove `base` qualifier on `ResponseStream`.
+* Add support for clients to send KEEPALIVE pings.
+
+## 3.2.1
+
+* `package:http` now supports more versions: `>=0.13.0 <2.0.0`.
+* `package:protobuf` new supports more versions: `>=2.0.0 <4.0.0`.
+
+## 3.2.0
+
+* `ChannelOptions` now exposes `connectTimeout`, which is used on the
+  socket connect. This is used to specify the maximum allowed time to wait
+  for a connection to be established. If `connectTime` is longer than the system
+  level timeout duration, a timeout may occur sooner than specified in
+  `connectTimeout`. On timeout, a `SocketException` is thrown.
+* Require Dart 2.17 or greater.
+* Fix issue [#51](https://github.com/grpc/grpc-dart/issues/51), add support for custom error handling.
+* Expose client IP address to server
+* Add a `channelShutdownHandler` argument to `ClientChannel` and the subclasses.
+  This callback can be used to react to channel shutdown or termination.
+* Export the `Code` protobuf enum from the `grpc.dart` library.
+* Require Dart 3.0.0 or greater.
+
+## 3.1.0
+
+* Expose a stream for connection state changes on ClientChannel to address
+  [#428](https://github.com/grpc/grpc-dart/issues/428).
+  This allows users to react to state changes in the connection.
+* Fix [#576](https://github.com/grpc/grpc-dart/issues/576): set default
+  `:authority` value for UDS connections to `localhost` instead of using
+  UDS path. Using path triggers checks in HTTP2 servers which
+  attempt to validate `:authority` value.
+
+## 3.0.2
+
+* Fix compilation on the Web with DDC.
+
+## 3.0.1
+
+* Require `package:googleapis_auth` `^1.1.0`
+* Fix issues [#421](https://github.com/grpc/grpc-dart/issues/421) and
+  [#458](https://github.com/grpc/grpc-dart/issues/458). Validate
+  responses according to gRPC/gRPC-Web protocol specifications: require
+  200 HTTP status and a supported `Content-Type` header to be present, as well
+  as `grpc-status: 0` header. When handling malformed responses make effort
+  to translate HTTP statuses into gRPC statuses.
+* Add GrpcOrGrpcWebClientChannel which uses gRPC on all platforms except web,
+  on which it uses gRPC-web.
+* `GrpcError` now exposes response trailers via `GrpcError.trailers`.
+
+## 3.0.0
+
+* Migrate library and tests to null safety.
+* Require Dart 2.12 or greater.
+
+## 2.9.0
+
+* Added support for compression/decompression, which can be configured through
+  `ChannelOptions` constructor's `codecRegistry` parameter or adding the
+  `grpc-accept-encoding` to `metadata` parameter of `CallOptions` on the client
+  side and `codecRegistry` parameter to `Server` on the server side.
+  Outgoing rpc can be compressed using the `compression` parameter on the
+  `CallOptions`.
+* Fix issue [#206](https://github.com/grpc/grpc-dart/issues/206). Prevent an
+  exception to be thrown when a web connection stream is closed.
+* Add XHR raw response to the GrpcError for a better debugging
+  ([PR #423](https://github.com/grpc/grpc-dart/pulls/423)).
+
+Note: this is the last release supporting SDK < 2.12. Next release will
+be nullsafe and thus require SDK >= 2.12.
+
+## 2.8.0
+
+* Added support for client interceptors, which can be configured through
+  `Client` constructor's `interceptors` parameter. Interceptors will be
+  executed by `Client.$createStreamingCall` and `Client.$createUnaryCall`.
+  Using interceptors requires regenerating client stubs using version 19.2.0 or
+  newer of protobuf compiler plugin.
+* `Client.$createCall` is deprecated because it does not invoke client
+  interceptors.
+* Fix issue [#380](https://github.com/grpc/grpc-dart/issues/380) causing
+  incorrect duplicated headers in gRPC-Web requests.
+* Change minimum required Dart SDK to 2.8 to enable access to Unix domain sockets.
+* Add support for Unix domain sockets in `Socket.serve` and `ClientChannel`.
+* Fix issue [#331](https://github.com/grpc/grpc-dart/issues/331) causing
+  an exception in `GrpcWebClientChannel.terminate()`.
+
+## 2.7.0
+
+* Added decoding/parsing of `grpc-status-details-bin` to pass all response
+  exception details to the `GrpcError` thrown in Dart, via
+  [#349](https://github.com/grpc/grpc-dart/pull/349).
+* Dart SDK constraint is bumped to `>=2.3.0 <3.0.0` due to language version
+  in the generated protobuf code.
+
+## 2.6.0
+
+* Create gRPC servers and clients with [Server|Client]TransportConnection.
+  This allows callers to provide their own transport configuration, such
+  as their own implementation of streams and sinks instead of sockets.
+
+## 2.5.0
+
+* Expose a `validateClient` method for server credentials so gRPC server
+  users may know when clients are loopback addresses.
+
+## 2.4.1
+
+* Plumb stacktraces through request / response stream error handlers.
+* Catch and forward any errors decoding the response.
+
+## 2.4.0
+
+* Add the ability to bypass CORS preflight requests.
+
+## 2.3.0
+
+* Revert [PR #287](https://github.com/grpc/grpc-dart/pull/287), which allowed
+using gRPC-web in native environments but also broke streaming.
+
+## 2.2.0+1
+
+* Relax `crypto` version dependency constraint from `^2.1.5` to `^2.1.4`.
+
+## 2.2.0
+
+* Added `applicationDefaultCredentialsAuthenticator` function for creating an
+  authenticator using [Application Default Credentials](https://cloud.google.com/docs/authentication/production).
+* Less latency by using the `tcpNoDelay` option for sockets.
+* Support grpc-web in a non-web setting.
+
+## 2.1.3
+
+* Fix bug in grpc-web when receiving an empty trailer.
+* Fix a state bug in the server.
+
+## 2.1.2
+
+* Fix bug introduced in 2.1.1 where the port would be added to the default authority when making a
+  secure connection.
+
+## 2.1.1
+
+* Fix bug introduced in 2.1.0 where an explicit `authority` would not be used when making a secure
+  connection.
+
+## 2.1.0
+
+* Do a health check of the http2-connection before making request.
+* Introduce `ChannelOptions.connectionLimit` the longest time a single connection is used for new
+  requests.
+* Use Tcp.nodelay to improve client call speed.
+* Use SecureSocket supportedProtocols to save a round trip when establishing a secure connection.
+* Allow passing http2 `ServerSettings` to `Server.serve`.
+
+## 2.0.3
+
+* GrpcError now implements Exception to indicate it can be reasonably handled.
+
+## 2.0.2
+
+* Fix computation of the audience given to metadata providers to include the scheme.
+
+## 2.0.1
+
+* Fix computation of authority. This should fix authorization.
+
+## 2.0.0+1
+
+* Fix imports to ensure `grpc_web.dart` has no accidental transitive dependencies on dart:io.
+
+## 2.0.0
+
+* Add initial support for grpc-web.
+  See `example/grpc-web` for an example of this working.
+* **Breaking**: `grpc.dart` no longer exposes `ClientConnection`. It was supposed to be an internal
+  abstraction.
+* **Breaking**: `grpc.dart` no longer exposes the deprecated `ServerHandler`.
+  It was supposed to be an internal abstraction.
+* `service_api.dart` no longer exports Server - it has never been used by the generated code.
+
+## 1.0.3
+
+* Allow custom user agent with a `userAgent` argument for `ChannelOptions()`.
+* Allow specifying `authority` for `ChannelCredentials.insecure()`.
+* Add `userAgent` as an optional named argument for `clientConnection.createCallHeaders()`.
+
+## 1.0.2
+
+* Fix bug where the server would crash if the client would break the connection.
+
+## 1.0.1
+
+* Add `service_api.dart` that only contains the minimal imports needed by the code generated by
+  protoc_plugin.
+
+## 1.0.0+1
+
+* Support package:http2  1.0.0.
+
+## 1.0.0
+
+* Graduate package to 1.0.
+
+## 0.6.8+1
+
+* Removes stray files that where published by accident in version 0.6.8.
+
+## 0.6.8
+
+* Calling `terminate()` or `shutdown()` on a channel doesn't throw error if the
+channel is not yet open.
+
+## 0.6.7
+
+* Support package:test 1.5.
+
+## 0.6.6
+
+* Support `package:http` `>=0.11.3+17 <0.13.0`.

+
+## 0.6.0+1
+
+* Updated implementation to use new Dart 2 APIs using
+[dart2_fix](https://github.com/dart-lang/dart2_fix).
+
+## 0.6.0
+
+* Dart SDK upper constraint raised to declare compatibility with Dart 2.0 stable.
+
+## 0.5.0
+
+* Breaking change: The package now exclusively supports Dart 2.

+///  Example 1: Pack and unpack a message in C++.
+///
+///      Foo foo = ...;

+///      Any any = Any.pack(foo);
+///      ...
+///      if (any.is(Foo.class)) {

+///      // or ...
+///      if (any.isSameTypeAs(Foo.getDefaultInstance())) {
+///        foo = any.unpack(Foo.getDefaultInstance());
+///      }
+///
+///   Example 3: Pack and unpack a message in Python.
+///
+///      foo = Foo(...)
+///      any = Any()
+///      any.Pack(foo)
+///      ...
+///      if any.Is(Foo.DESCRIPTOR):
+///        any.Unpack(foo)
+///        ...
+///

+///  The pack methods provided by protobuf library will by default use

+///  methods only use the fully qualified type name after the last '/'
+///  in the type URL, for example "foo.bar.com/x/y.z" will yield type
+///  name "y.z".
+///
+///  JSON
+///  ====
+///  The JSON representation of an `Any` value uses the regular
+///  representation of the deserialized, embedded message, with an
+///  additional field `@type` which contains the type URL. Example:
+///
+///      package google.profile;
+///      message Person {
+///        string first_name = 1;
+///        string last_name = 2;

+///
+///      {
+///        "@type": "type.googleapis.com/google.profile.Person",
+///        "firstName": <string>,
+///        "lastName": <string>
+///      }
+///
+///  If the embedded message type is well-known and has a custom JSON
+///  representation, that representation will be embedded adding a field
+///  `value` which holds the custom JSON in addition to the `@type`
+///  field. Example (for message [google.protobuf.Duration][]):
+///
+///      {
+///        "@type": "type.googleapis.com/google.protobuf.Duration",
+///        "value": "1.212s"

+///  # JSON Mapping
+///
+///  In JSON format, the Timestamp type is encoded as a string in the
+///  [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+///  format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+///  where {year} is always expressed using four digits while {month}, {day},
+///  {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+///  seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+///  are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+///  is required. A proto3 JSON serializer should always use UTC (as indicated by
+///  "Z") when printing the Timestamp type and a proto3 JSON parser should be
+///  able to accept both UTC and other timezones (as indicated by an offset).
+///
+///  For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+///  01:30 UTC on January 15, 2017.
+///
+///  In JavaScript, one can convert a Date object to this format using the
+///  standard
+///  [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
+///  method. In Python, a standard `datetime.datetime` object can be converted
+///  to this format using
+///  [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
+///  the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
+///  the Joda Time's [`ISODateTimeFormat.dateTime()`](
+///  http://joda-time.sourceforge.net/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime()
+///  ) to obtain a formatter capable of generating timestamps in this format.

+# Description
+The grpc-web example shows how to use the Dart gRPC library with a gRPC-Web capable server. 
+
+This is meant to be used with the echo example provided by the grpc-web repository. The definition of the service is given in echo.proto. 
+
+# Prerequisites
+
+Install 'webdev', by running
+
+```sh
+$ dart pub global activate webdev
+```
+
+You will need a clone of the [grpc-web](https://github.com/grpc/grpc-web) repository to run the example server.
+
+# Run the sample code
+Follow the instructions for starting the grpc-web example server. The simplest version of this involves running the grpc-web server in a docker container with:
+
+```sh
+$ docker-compose up node-server envoy commonjs-client
+```
+
+To compile and run the example, assuming you are in the root of the grpc-web
+folder, i.e., .../example/grpc-web/, first get the dependencies by running:
+
+```sh
+$ dart pub get
+```
+
+Compile and run the website with:
+
+```sh
+$ webdev serve web:9000
+```
+
+Note that the alternate port (9000) is necessary because the grpc-web server runs the grpc server on port 8080 by default (the same as webdev).
+
+You can then navigate to http://localhost:9000/ to try out the example.
+
+# Regenerate the stubs
+
+If you have made changes to the message or service definition in
+`protos/echo.proto` and need to regenerate the corresponding Dart files,
+you will need to have protoc version 3.0.0 or higher and the Dart protoc plugin
+version 16.0.0 or higher on your PATH.
+
+To install protoc, see the instructions on
+[the Protocol Buffers website](https://developers.google.com/protocol-buffers/).
+
+The easiest way to get the Dart protoc plugin is by running
+
+```sh
+$ dart pub global activate protoc_plugin
+```
+
+and follow the directions to add `~/.pub-cache/bin` to your PATH, if you haven't
+already done so.
+
+You can now regenerate the Dart files by running
+
+```sh
+$ protoc --dart_out=grpc:lib/src/generated -Iprotos protos/echo.proto
+```

+# Description
+The hello world server and client demonstrate how to use Dart gRPC libraries to
+perform unary RPCs.
+
+See the definition of the hello world service in `protos/helloworld.proto`.
+
+# Run the sample code
+To compile and run the example, assuming you are in the root of the helloworld
+folder, i.e., .../example/helloworld/, first get the dependencies by running:
+
+```sh
+$ dart pub get
+```
+## Run TCP sample code
+
+Start the server:
+
+```sh
+$ dart bin/server.dart
+```
+
+Likewise, to run the client:
+
+```sh
+$ dart bin/client.dart
+```
+## Run UDS sample code
+
+Start the server:
+
+```sh
+$ dart bin/unix_server.dart
+```
+
+Likewise, to run the client:
+
+```sh
+$ dart bin/unix_client.dart
+```
+
+>**Note** the `UDS` only support *nix plantform.
+
+# Regenerate the stubs
+
+If you have made changes to the message or service definition in
+`protos/helloworld.proto` and need to regenerate the corresponding Dart files,
+you will need to have protoc version 3.0.0 or higher and the Dart protoc plugin
+version 0.7.9 or higher on your PATH.
+
+To install protoc, see the instructions on
+[the Protocol Buffers website](https://developers.google.com/protocol-buffers/).
+
+The easiest way to get the Dart protoc plugin is by running
+
+```sh
+$ pub global activate protoc_plugin
+```
+
+and follow the directions to add `~/.pub-cache/bin` to your PATH, if you haven't
+already done so.
+
+You can now regenerate the Dart files by running
+
+```sh
+$ protoc --dart_out=grpc:lib/src/generated -Iprotos protos/helloworld.proto
+```

+# Regenerate the stubs
+
+If you have made changes to the message or service definition in
+`protos/route_guide.proto` and need to regenerate the corresponding Dart files,
+you will need to have protoc version 3.0.0 or higher and the Dart protoc plugin
+version 0.7.9 or higher on your PATH.
+
+To install protoc with Dart support, take these steps:
+
+1. Install the `protoc` matching your development operating system from
+[the Protocol Buffers releases page](https://github.com/google/protobuf/releases)
+(e.g. `protoc-3.5.1-osx-x86_64.zip` for macOS).
+
+1. Get the Dart protoc plugin by running
+
+    ```sh
+    $ dart pub global activate protoc_plugin
+    ```
+
+1. Add `~/.pub-cache/bin` to your PATH, if you haven't
+already done so.
+
+You can now regenerate the Dart files by running
+
+```sh
+$ protoc --dart_out=grpc:lib/src/generated -Iprotos protos/metadata.proto
