 * [#248](https://github.com/Icinga/icinga-powershell-framework/pull/248) Improves `Test-IcingaPerformanceCounterCategory` by creating an object for the Performance Counter category provided and checking if it is a valid object instead of relying on the registry which might not contain all categories in the correct language.
 * [#249](https://github.com/Icinga/icinga-powershell-framework/pull/249) Improves internal exception handler to get rid if misplaced `:` and adds all fields properly
 * [#250](https://github.com/Icinga/icinga-powershell-framework/pull/250) Improve error handling on plugin execution by informing the user if the plugin is simply not installed or the entire module was not loaded because of errors or missing dependencies
+* [#264](https://github.com/Icinga/icinga-powershell-framework/pull/264) Adds initial handling for handling link speeds or anything else by using new units and conversions, which were formerly used inside the Network plugin and corresponding provider
