         - Added support for `.SafeFireAndForget&lt;TException&gt;()`
         - Added `SafeFireAndForgetExtensions.SetDefaultExceptionHandling(Action&lt;Exception&gt; onException)` to set a default action for every call to `SafeFireAndForget`
         - Added `SafeFireAndForgetExtensions.Initialize(bool shouldAlwaysRethrowException = false)`. When set to `true` will rethrow every exception caught by `SafeFireAndForget`. Warning: `SafeFireAndForgetExtensions.Initialize(true)` is only recommended for DEBUG environments.
+        - Added support for `Exception innerException` to `InvalidCommandParameterException`
         - Breaking Change: Changed default value to `continueOnCapturedContext = false`. This improves performance by not requiring a context switch when `.SafeFireAndForget()` and `IAsyncCommand` have completed.
