 ## Bugfixes
 
 * [#246](https://github.com/Icinga/icinga-powershell-plugins/pull/246) Fixes wrong `UNKNOWN` on `Invoke-IcingaCheckService` while using service display name with the `-Service` argument instead of the service name
+* [#261](https://github.com/Icinga/icinga-powershell-plugins/issues/261) Fixes `Invoke-IcingaCheckCertificate` which always included the CertStore because no option to not check the certificate store was available
 * [#262](https://github.com/Icinga/icinga-powershell-plugins/pull/262) Fixes method NULL exception on empty EventLog entries for `Invoke-IcingaCheckEventLog`
