 # Changes
 
 ## Unreleased - 2021-xx-xx
-* Remove `config` module. `ServiceConfig`, `ServiceRuntime` public types are removed due to this change. [#349]
+* Minimum supported Rust version (MSRV) is now 1.52.
+
+
+## 2.0.0-beta.6 - 2021-10-11
+* Add experimental (semver-exempt) `io-uring` feature for enabling async file I/O on linux. [#374]
+* Server no long listens to `SIGHUP` signal. Previously, the received was not used but did block
+  subsequent exit signals from working. [#389]
+* 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]
