@@ -0,0 +1,113 @@
+## 3.2.2
+
+* Require Dart 3.2
+* Move to `dart-lang/http` monorepo.
+
+## 3.2.1
+
+* Populate the pubspec `repository` field.
+
+## 3.2.0
+
+* Honor the `preserveHeaderCase` argument to `MultiHeaders.set` and `.add`.
+
+## 3.1.0
+
+* Add `HttpMultiServer.bindSecure` to match `HttpMultiServer.bind`.
+
+## 3.0.1
+
+* Fix an issue where `bind` would bind to the `anyIPv6` address in unsupported
+  environments.
+
+## 3.0.0
+
+* Migrate to null safety.
+
+## 2.2.0
+
+* Preparation for [HttpHeaders change]. Update signature of `MultiHeaders.add()`
+  and `MultiHeaders.set()` to match new signature of `HttpHeaders`. The
+  parameter is not yet forwarded and will not behave as expected.
+
+  [HttpHeaders change]: https://github.com/dart-lang/sdk/issues/39657
+
+## 2.1.0
+
+* Add `HttpMultiServer.bind` static which centralizes logic around common local
+  serving scenarios - handling a more flexible 'localhost' and listening on
+  'any' hostname.
+* Update SDK constraints to `>=2.1.0 <3.0.0`.
+
+## 2.0.6
+
+* If there is a problem starting a loopback Ipv6 server, don't keep the Ipv4
+  server open when throwing the exception.
+
+## 2.0.5
+
+* Update SDK constraints to `>=2.0.0-dev <3.0.0`.
+
+## 2.0.4
+
+* Declare support for `async` 2.0.0.
+
+## 2.0.3
+
+* Fix `HttpMultiServer.loopback()` and `.loopbackSecure()` for environments that
+  don't support IPv4.
+
+## 2.0.2
+
+* Fix a dependency that was incorrectly marked as dev-only.
+
+## 2.0.1
+
+* Fix most strong mode errors and warnings.
+
+## 2.0.0
+
+* **Breaking:** Change the signature of `HttpMultiServer.loopbackSecure()` to
+  match the new Dart 1.13 `HttpServer.bindSecure()` signature. This removes the
+  `certificateName` named parameter and adds the required `context` parameter
+  and the named `v6Only` and `shared` parameters.
+
+* Added `v6Only` and `shared` parameters to `HttpMultiServer.loopback()` to
+  match `HttpServer.bind()`.
+
+## 1.3.2
+
+* Eventually stop retrying port allocation if it fails repeatedly.
+
+* Properly detect socket errors caused by already-in-use addresses.
+
+## 1.3.1
+
+* `loopback()` and `loopbackSecure()` recover gracefully if an ephemeral port is
+  requested and the located port isn't available on both IPv4 and IPv6.
+
+## 1.3.0
+
+* Add support for `HttpServer.autoCompress`.
+
+## 1.2.0
+
+* Add support for `HttpServer.defaultResponseHeaders.clear`.
+
+* Fix `HttpServer.defaultResponseHeaders.remove` and `.removeAll`.
+
+## 1.1.0
+
+* Add support for `HttpServer.defaultResponseHeaders`.
+
+## 1.0.2
+
+* Remove the workaround for [issue 19815][].
+
+## 1.0.1
+
+* Ignore errors from one of the servers if others are still bound. In
+  particular, this works around [issue 19815][] on some Windows machines where
+  IPv6 failure isn't discovered until we try to connect to the socket.

+An implementation of `dart:io`'s [HttpServer][] that wraps multiple servers and
+forwards methods to all of them. It's useful for serving the same application on
+multiple network interfaces while still having a unified way of controlling the
+servers. In particular, it supports serving on both the IPv4 and IPv6 loopback
+addresses using [HttpMultiServer.loopback][].
+
+```dart
+import 'package:http_multi_server/http_multi_server.dart';
+import 'package:shelf/shelf.dart' as shelf;
+import 'package:shelf/shelf_io.dart' as shelf_io;
+
+void main() async {
+  // Both http://127.0.0.1:8080 and http://[::1]:8080 will be bound to the same
+  // server.
+  var server = await HttpMultiServer.loopback(8080);
+  shelf_io.serveRequests(server, (request) {
+    return shelf.Response.ok("Hello, world!");
+  });
+}
+```
