 # Changes
 
 ## Unreleased - 2021-xx-xx
+* Remove `config` module. `ServiceConfig`, `ServiceRuntime` public types are removed due to this change. [#349]
+* Remove `ServerBuilder::configure` [#349]
+* Add `io-uring` feature for enabling async file I/O on linux. [#374]
+* Server no long listens to SIGHUP signal.
+  It actually did not take any action when receiving SIGHUP, the only thing SIGHUP did was to stop
+  the Server from receiving any future signal, because the `Signals` future stops on the first
+  signal received [#389]
+
+[#374]: https://github.com/actix/actix-net/pull/374
+[#349]: https://github.com/actix/actix-net/pull/349
+[#389]: https://github.com/actix/actix-net/pull/389
+
+
+## 2.0.0-beta.5 - 2021-04-20
 * Server shutdown would notify all workers to exit regardless if shutdown is graceful.
   This would make all worker shutdown immediately in force shutdown case. [#333]
