+# Changelog
+
+Notable changes to this project are documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/) and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+Breaking changes (😱!!!):
+
+New features:
+
+Bugfixes:
+
+Other improvements:
+
+## [v11.0.0](https://github.com/purescript-contrib/purescript-affjax/releases/tag/v11.0.0) - 2020-09-06
+
+- Adds support for the `timeout` option in `Request` (#151)
+
+## [v10.1.0](https://github.com/purescript-contrib/purescript-affjax/releases/tag/v10.1.0) - 2020-06-07
+
+- Added `Newtype` instance for `StatusCode` (@ford-prefect)
+
+## [v10.0.0](https://github.com/purescript-contrib/purescript-affjax/releases/tag/v10.0.0) - 2019-11-03
+
+- Updated for latest `purescript-form-urlencoded`.
+- Some helper functions were combined to accept `Maybe RequestBody` rather than having two variations of each.
+- All request functions now return `Either Error _` - the `Aff` error channel is no longer used to capture errors from the `XHR` object, and the provided `Error` type captures the various possible error cases that can occur.
+- `retry` was removed.
+
+## [v9.0.1](https://github.com/purescript-contrib/purescript-affjax/releases/tag/v9.0.1) - 2019-09-05
+
+- Ensure version mismatch with `purescript-form-urlencoded` does not compile, potentially resulting in runtime errors (spotted by @menelaos)
+- Don't override `nodejsBaseUrl` already set in `xhr2` on node (@paul-rouse)
+
+## [v9.0.0](https://github.com/purescript-contrib/purescript-affjax/releases/tag/v9.0.0) - 2019-03-11
+
+- Update for latest `purescript-argonaut-core`
+
+## [v8.0.0](https://github.com/purescript-contrib/purescript-affjax/releases/tag/v8.0.0) - 2019-02-23
+
+- Updated `purescript-web-xhr` dependency
+- Renamed functions in the `RequestHeader` / `ResponseHeader` modules to no longer prefix values with the module name
+
+## [v7.0.2](https://github.com/purescript-contrib/purescript-affjax/releases/tag/v7.0.2) - 2019-02-09
+
+- XHR timeouts are now caught and raised through `Aff`'s error channel (@acple)
+
+## [v7.0.1](https://github.com/purescript-contrib/purescript-affjax/releases/tag/v7.0.1) - 2019-01-31
+
+- Fixed an incorrect `request` example in the doc comments (@jhrcek)
+
+## [v7.0.0](https://github.com/purescript-contrib/purescript-affjax/releases/tag/v7.0.0) - 2018-08-12
+
+Lots of things were renamed in this release to better match their current functionality:
+
+- The `affjax` function is now `request`
+- The `AffjaxRequest` record is now `Request`
+- The `AffjaxResponse` record is now `Response`
+- The `response` field of `Response` is now `body`
+- The `Request` type is now `RequestBody`
+- The `Response` type is now `ResponseFormat`
+- The `Request` record now has a `responseFormat` field, rather than it being a separate argument to `request`
+
+(Most of the new names by @paldepind).
+
+Additionally, errors that occur during decoding a response no longer cause an entire request to fail. The `body` value is now `Either ResponseFormatError a`, so that other details about the response can still be inspected (status code, for example), even if the response body fails to decode. The `ResponseFormatError` value also carries the response body as a `Foreign` value, in case there is some further special handling that can be performed externally.
+
+## [v6.0.1](https://github.com/purescript-contrib/purescript-affjax/releases/tag/v6.0.1) - 2018-08-05
