+## Unreleased
+
+* Setting a cookie's SameSite property, explicitly, to `SameSite::None` will now
+  result in `SameSite=None` being sent with the response Set-Cookie header.
+  To create a cookie without a SameSite attribute, remove any calls setting same_site.
+* actix-http support for Actors messages was moved to actix-http crate and is enabled 
+  with feature `actors`
+
 ## 2.0.0
 
+* `HttpServer::start()` renamed to `HttpServer::run()`. It also possible to
+  `.await` on `run` method result, in that case it awaits server exit.
+
 * `App::register_data()` renamed to `App::app_data()` and accepts any type `T: 'static`.
   Stored data is available via `HttpRequest::app_data()` method at runtime.
 
 * Extractor configuration must be registered with `App::app_data()` instead of `App::data()`
 
 * Sync handlers has been removed. `.to_async()` method has been renamed to `.to()`
-
   replace `fn` with `async fn` to convert sync handler to async
 
-* `TestServer::new()` renamed to `TestServer::start()`

 # Changes
 
+## [2.0.0-alpha.3] - 2020-05-08
+
+### Fixed
+
+* Correct spelling of ConnectError::Unresolved [#1487]
+* Fix a mistake in the encoding of websocket continuation messages wherein
+  Item::FirstText and Item::FirstBinary are each encoded as the other.
+
+### Changed
+
+* Implement `std::error::Error` for our custom errors [#1422]
+* Remove `failure` support for `ResponseError` since that crate
+  will be deprecated in the near future.
+
+[#1422]: https://github.com/actix/actix-web/pull/1422
+[#1487]: https://github.com/actix/actix-web/pull/1487
+
+## [2.0.0-alpha.2] - 2020-03-07
+
+### Changed
+
+* Update `actix-connect` and `actix-tls` dependency to 2.0.0-alpha.1. [#1395]
+
+* Change default initial window size and connection window size for HTTP2 to 2MB and 1MB respectively
+  to improve download speed for awc when downloading large objects. [#1394]
+
+* client::Connector accepts initial_window_size and initial_connection_window_size HTTP2 configuration. [#1394]
+
+* client::Connector allowing to set max_http_version to limit HTTP version to be used. [#1394]
+
+[#1394]: https://github.com/actix/actix-web/pull/1394
+[#1395]: https://github.com/actix/actix-web/pull/1395
+
+## [2.0.0-alpha.1] - 2020-02-27
+
+### Changed
+
+* Update the `time` dependency to 0.2.7.
+* Moved actors messages support from actix crate, enabled with feature `actors`.
+* Breaking change: trait MessageBody requires Unpin and accepting Pin<&mut Self> instead of &mut self in the poll_next().
+* MessageBody is not implemented for &'static [u8] anymore.
+
+### Fixed
+
+* Allow `SameSite=None` cookies to be sent in a response.
+
 ## [1.0.1] - 2019-12-20
