 ### Bugfixes
 
+* [#231](https://github.com/Icinga/icinga-powershell-framework/issues/231) Fixes error while using Icinga Director Self-Service API, in case the host or host API key was deleted inside the Icinga Director and the installation wizard was called with the correct template key, while the old host key was still present inside the Icinga for Windows configuration
 * [#232](https://github.com/Icinga/icinga-powershell-framework/pull/232) Fixes wrong encoding while using REST-Api checks experimental feature, and now forces UTF8
 * [#240](https://github.com/Icinga/icinga-powershell-framework/pull/240) While filtering for certain services with `Get-IcingaServices`, there were some attributes missing from the collection. These are now added resulting in always correct output data.
 * [#245](https://github.com/Icinga/icinga-powershell-framework/pull/245) Fixes loading of `.pfx` certificates by properly checking the file type
