**Changes / Improvements / Optimizations:**

DietPi-Config | WiFi: Added support for applying up-to 5 SSIDs: #368

DietPi-Drive_Manager | Samba Mount: Now mounts with user and group of 'DietPi'. This matches group permissions for DietPi applications that will prevent permission failure, when samba is used for userdata location: #2067

DietPi-Software | Pi-hole: You can now install Pi-hole again on Debian Jessie system, as support got re-enabled with Pi-hole v4.0 FTLDNS update.

**Bug Fixes:**

General | Resolved an issue where 1st run setup password prompt, would run twice. Once on 1st run and once after updates are completed.

General | Resolved an external issue where in very rare cases WiFi interfaces were not initiated successfully: #2074

DietPi-Config | Sparky SBC: Resolved an issue where Piano DAC firmware was not being fully installed.

DietPi-Config | Resolved an issue with selected WiFi SSID not being correctly applied: #2070 (comment)

DietPi-Drive_Manager | RockPro64: Resolved an issue where mtdblock devices would show up in the list. As far as well can tell, these are not currently required for EMMC/SD/USB devices. To ensure the list only shows actual devices, we have disabled them from showing up in view: #2067 (comment)

DietPi-Postboot | Resolved an issue where user scripts were not being executed '/var/lib/dietpi/postboot.d/*'.

Optional "ready to run" optimised software choices with dietpi-software.
Feature rich configuration tool for your device with dietpi-config.

DietPi's web hosting is powered by myVirtualserver.

A wide range of SBCs and VMs are supported. Click here for the full list.


DietPi is an extremely lightweight Debian OS. With images starting at 400MB, that's 3x lighter than 'Raspbian Lite'. It is highly optimised for minimal CPU and RAM resource usage, ensuring your SBC always runs at its maximum potential. The programs use lightweight Whiptail menus. You'll spend less time staring at the command line, and more time enjoying DietPi.

Use dietpi-software to quickly and easily install popular software that's "Ready to run" and optimised for your system. Only the software you need is installed. Use dietpi-process to control which installed software has higher or lower priority levels (nice, affinity, policy scheduler).

dietpi-update automatically checks for updates and informs you when they are available. Update instantly, without having to write a new image. dietpi-automation Allows you to completely automate a DietPi installation with no user input. Simply by configuring dietpi.txt before powering on.
