 Enhancements:
 - DietPi-Benchmark | The benchmark script has been moved to /boot/dietpi/dietpi-benchmark and a shell alias has been added, so it can now be called directly from the console as "dietpi-benchmark" without having to browse through dietpi-config first.
+- DietPi-Tools | dietpi-servarr_to_ram: The original script DietPi-arr_to_RAM was renamed to dietpi-servarr_to_ram, got Prowlarr support and improved installation robustness.
 
 Bug fixes:
 - DietPi-Globals | G_AG_CHECK_INSTALL_PREREQ: Resolved an issue where the package installation is skipped even if the package was removed with only config files left. Many thanks to @Sympatron for reporting this issue: https://github.com/MichaIng/DietPi/issues/7772
