-## [0.3.4] / 23 June 2022
-- [Adds `ActorRegistry`-capable overloads to the `WithShardRegion<TKey>` methods](https://github.com/akkadotnet/Akka.Hosting/pull/70)
\ No newline at end of file
+## [0.4.0] / 18 July 2022
+- [Add `Microsoft.Extensions.Logging.ILoggerFactory` logging support](https://github.com/akkadotnet/Akka.Hosting/pull/72)
+
+You can now use `ILoggerFactory` from Microsoft.Extensions.Logging as one of the sinks for Akka.NET logger. This logger will use the `ILoggerFactory` service set up inside the dependency injection `ServiceProvider` as its sink.
+
+Example:
+```
+builder.Services.AddAkka("MyActorSystem", (configurationBuilder, serviceProvider) =>
+{
+    configurationBuilder
+        .AddHocon("akka.loglevel = DEBUG")
+        .WithLoggerFactory()
+        .WithActors((system, registry) =>
+        {
+            var echo = system.ActorOf(act =>
+            {
+                act.ReceiveAny((o, context) =>
+                {
+                    Logging.GetLogger(context.System, "echo").Info($"Actor received {o}");
+                    context.Sender.Tell($"{context.Self} rcv {o}");
+                });
+            }, "echo");
+            registry.TryRegister<Echo>(echo); // register for DI
+        });
+});
+```
+
+There are two `Akka.Hosting` extension methods provided:
+- `.WithLoggerFactory()`: Replaces all Akka.NET loggers with the new `ILoggerFactory` logger.
+- `.AddLoggerFactory()`: Inserts the new `ILoggerFactory` logger into the Akka.NET logger list.
+
+__Log Event Filtering__
+
+There will be two log event filters acting on the final log input, the Akka.NET `akka.loglevel` setting and the `Microsoft.Extensions.Logging` settings, make sure that both are set correctly or some log messages will be missing.
+
+To set up the `Microsoft.Extensions.Logging` log filtering, you will need to edit the `appsettings.json` file. Note that we also set the `Akka` namespace to be filtered at debug level in the example below.
+
+```json
+{
+  "Logging": {
+    "LogLevel": {
+      "Default": "Information",
+      "Microsoft": "Warning",
+      "Microsoft.Hosting.Lifetime": "Information",
+      "Akka": "Debug"
+    }
+  }
+}
+```
