 * [#617](https://github.com/Icinga/icinga-powershell-framework/issues/617) Fixes failing calls for plugins which use a switch argument like `-NoPerfData`, which is followed directly by the `-ThresholdInterval` argument
 * [#621](https://github.com/Icinga/icinga-powershell-framework/pull/621) Fixes `-ThresholdInterval` key detection on newer systems
 * [#645](https://github.com/Icinga/icinga-powershell-framework/pull/645) Fixes error and exception handling while using API-Checks, which now will in most cases always return a proper check-result object and also abort while running into plugin execution errors, in case a server is not reachable by the time sync plugin for example
+* [#646](https://github.com/Icinga/icinga-powershell-framework/pull/646) Fixes REST-Api to allow arguments for check execution with and without leading `-`
