-## [0.4.0] / 18 July 2022
-- [Add `Microsoft.Extensions.Logging.ILoggerFactory` logging support](https://github.com/akkadotnet/Akka.Hosting/pull/72)
+## [0.4.1] / 21 July 2022
+- [Fix `Microsoft.Extensions.Logging.ILoggerFactory` logging support](https://github.com/akkadotnet/Akka.Hosting/pull/81)
+- [Add `InMemory` snapshot store and journal persistence support](https://github.com/akkadotnet/Akka.Hosting/pull/84)
 
-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.
+Due to a bad API design, we're rolling back the `Microsoft.Extensions.Logging.ILoggerFactory` logger support introduced in version 0.4.0, the 0.4.0 NuGet version is now considered as deprecated in support of the new API design introduced in version 0.4.1.
+
+__Logger Configuration Support__
+
+You can now use the new `AkkaConfigurationBuilder` extension method called `ConfigureLoggers(Action<LoggerConfigBuilder>)` to configure how Akka.NET logger behave.
 
 Example:
-```
-builder.Services.AddAkka("MyActorSystem", (configurationBuilder, serviceProvider) =>
+```csharp
+builder.Services.AddAkka("MyActorSystem", configurationBuilder =>
 {
     configurationBuilder
-        .AddHocon("akka.loglevel = DEBUG")
-        .WithLoggerFactory()
+        .ConfigureLoggers(setup =>
+        {
+            // Example: This sets the minimum log level
+            setup.LogLevel = LogLevel.DebugLevel;
+            
+            // Example: Clear all loggers
+            setup.ClearLoggers();
+            
+            // Example: Add the default logger
+            // NOTE: You can also use setup.AddLogger<DefaultLogger>();
+            setup.AddDefaultLogger();
+            
+            // Example: Add the ILoggerFactory logger
+            // NOTE:
+            //   - You can also use setup.AddLogger<LoggerFactoryLogger>();
+            //   - To use a specific ILoggerFactory instance, you can use setup.AddLoggerFactory(myILoggerFactory);
+            setup.AddLoggerFactory();

-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.
+A complete code sample can be viewed [here](https://github.com/akkadotnet/Akka.Hosting/tree/dev/src/Examples/Akka.Hosting.LoggingDemo).
+
+Exposed properties are:
+- `LogLevel`: Configure the Akka.NET minimum log level filter, defaults to `InfoLevel`
+- `LogConfigOnStart`: When set to true, Akka.NET will log the complete HOCON settings it is using at start up, this can then be used for debugging purposes.
 
-__Log Event Filtering__
+Currently supported logger methods:
+- `ClearLoggers()`: Clear all registered logger types.
+- `AddLogger<TLogger>()`: Add a logger type by providing its class type.
+- `AddDefaultLogger()`: Add the default Akka.NET console logger.
+- `AddLoggerFactory()`: Add the new `ILoggerFactory` logger.
+
+__Microsoft.Extensions.Logging.ILoggerFactory Logging Support__
+
+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.
+
+__Microsoft.Extensions.Logging 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.

+__InMemory Snapshot Store And Journal Support__
+
+You can now use these `AkkaConfigurationBuilder` extension methods to enable `InMemory` persistence back end:
+- `WithInMemoryJournal()`: Sets the `InMemory` journal as the default journal persistence plugin
+- `WithInMemorySnapshotStore()`: Sets the `InMemory` snapshot store as the default snapshot-store persistence plugin.
