 #### Changes on check command execution
 
+**Breaking Change/Important Note:** Check Command configuration generated by Icinga for Windows 1.2.0 require Icinga for Windows 1.2.0 or later deployed on all systems, otherwise you will run into issues with an unknown command `Exit-IcingaPluginNotInstalled` error.
+
 As mentioned in [#95](https://github.com/Icinga/icinga-powershell-framework/issues/95) we should make sure that in case the Framework itself is not installed on a system or plugins are missing the user is informed about this. We do how ever not intend to print huge stack traces of PowerShell errors into the console, but inform in a minimalistic way about this.
 
 For this reason we will cover with a Try-Catch statement if the `Use-Icinga` command is executed and return a proper message and error code on failures. In addition we will now check of a plugin is installed before the execution of it, ensuring that in case it is not present on the system we receive an `Unknown` message that a certain plugin is not installed or present.
