 * [#40](https://github.com/Icinga/icinga-powershell-framework/issues/40) Adds support to set service recovery for the Icinga Agent and Icinga for Windows service, to restart them in case of a crash or error
 * [#485](https://github.com/Icinga/icinga-powershell-framework/issues/485) Adds new style for performance data labels, to use the multi output format, allowing for better filtering and visualisation with InfluxDB and Grafana
+* [#502](https://github.com/Icinga/icinga-powershell-framework/pull/502) Adds support for hostname override for old installer function `Start-IcingaAgentInstallWizard` [moreamazingnick]
 * [#525](https://github.com/Icinga/icinga-powershell-framework/pull/525) Adds new developer mode for `icinga` command and improved cache handling, to ensure within `-DeveloperMode` and inside a VS Code environment, the framework cache file is never overwritten, while still all functions are loaded and imported.
 * [#531](https://github.com/Icinga/icinga-powershell-framework/pull/531) Adds `Test-IcingaStateFile` and `Repair-IcingaStateFile`, which is integrated into `Test-IcingaAgent`, to ensure the Icinga Agent state file is healthy and not corrupt, causing the Icinga Agent to fail on start
 * [#534](https://github.com/Icinga/icinga-powershell-framework/pull/534) Improves Icinga and Director configuration generator, by wrapping PowerShell arrays inside `@()` instead of simply writing them comma separated
