Release Notes

May 2020 (version 6.29)

API Changes

  • Hardware info | The hardware info file /DietPi/dietpi/.hw_model should be now accessed at /boot/dietpi/.hw_model (see DietPi-RAMdisk removal below) and contains info now as NAME=VALUE like lines, which can be sourced from shell scripts.
  • Flag/Info files | /DietPi/dietpi/.update_available, /DietPi/dietpi/.timesync_exit_status, /DietPi/dietpi/.network and /tmp/.dietpi_motd have all been moved into a new runtime directory: /run/dietpi/
  • DietPi-Globals | The global variables G_HW_ARCH_DESCRIPTION and G_HW_MODEL_DESCRIPTION have been renamed to G_HW_ARCH_NAME and G_HW_MODEL_NAME. The new variables G_HW_UUID (DietPi-internal device UUID) and G_ROOTFS_DEV (RootFS device path) are available. On RPi additionally G_HW_REVISION, G_HW_PCB_REVISION, G_HW_MEMORY_SIZE and G_HW_MANUFACTURER are available, the revision code and its decoded information:
  • DietPi-Globals | G_RUN_CMD and G_ERROR_HANDLER have been removed and replaced with G_EXEC. Basically G_EXEC can be used the same way G_RUN_CMD was before and it is wider configurable to make manual G_ERROR_HANDLER usage obsolete where custom solution menu entries or command output parsing is required, e.g. to check for errors that do not produce exit codes. Visual change for regular DietPi users is that every error handled command can be retried, a subshell can be opened to investigate or fix the originating issue and, for experienced users, the command can be altered, e.g. if a download link has changed or an expected file has been moved manually to a new path. Further details can be found in the script: /boot/dietpi/func/dietpi-globals
  • DietPi-Globals | G_FILE_EXISTS has been removed, as it was used only a single time in our code and usually it needs to be checked and handled explicitly, whether it is a file, directory, symlink with or without existing target.
  • DietPi-Globals | The new global functions G_CHECK_CON and G_CHECK_DNS have been added to test general network connectivity and DNS resolver based on dietpi.txt settings.


  • NanoPi M4V2 | Initial hardware identifier (ID: 58) and support for this device has been added to DietPi. Many thanks to @purist doing this request.
  • NanoPi NEO Plus2 | Initial hardware identifier (ID: 57) and support for this device has been added to DietPi. Many thanks to @StephanStS for doing this request and creating an image: MichaIng/DietPi#2979 (comment)
  • PINE H64 | Initial hardware identifier (ID: 45) and support for this device has been added to DietPi. Many thanks to @unixino for doing this request: MichaIng/DietPi#3286
  • ROCK Pi S | Initial hardware identifier (ID: 73) and support for this device has been added to DietPi. Many thanks to @lwqcz for doing this request: MichaIng/DietPi#3365
  • Sparky SBC | Updated kernel drivers and SBC-specific service and config files
  • General | Switched to C.UTF-8 as default locale and for DietPi scripts. It is shipped statically by APT package, international and more lightweight compared to en_GB.UTF-8.
  • DietPi-RAMdisk | Removed from DietPi, which means that one can edit config files in /boot directory directly now. To keep performance for our scripts up, vmtouch is installed instead, which allows to lock files in native file system cache, configured to lock /boot/dietpi and /boot/dietpi.txt in cache by default. More info: MichaIng/DietPi#3288
  • DietPi-LED_control | LED trigger choices are now applied via udev rules, existing settings are migrated on DietPi-Update. This allows to skip running this script at boot and simplify the preboot script, which both reduces boot time a bid. Additionally, applied LED triggers can now be reset to system defaults, which removes related udev rules. Since the script is now for interactive usage only, it has been moved to /boot/dietpi/dietpi-led_control and an alias has been added to call it from console via dietpi-led_control command.
  • DietPi-Update | The DietPi auto update feature has been removed. Our updates require users attention, they often contain deeper changes, interactive elements and important information. We’ll instead add an auto APT upgrade feature at a later release, similar to “unattended-upgrades” but with the possibility to also upgrade non-security patches, right into dietpi-update. Checking for available updates is done as before on a daily basis if not disabled via dietpi.txt.
  • DietPi-Cron | Allows now to set the cron job output mail recipient. Cron mails are disabled by default since no MTA is preconfigured on DietPi. Additionally the execution times are now shown more clearly in 24h format.
  • DietPi-Autostart | When selecting a non-root auto login user, some required tasks, like permissions, are now applied automatically, based on autostart option. This especially allows non-root users to launch Kodi without applying permissions manually. Many thanks to @sbrl for requesting this feature: MichaIng/DietPi#3351
  • DietPi-Drive_Manager | GlusterFS fstab entries are now preserved. Many thanks to @Sudrien for implementing this addition: MichaIng/DietPi#3374
  • DietPi-Software | Domoticz: open-source home automation platform is now available for install. Many thanks to @AndyB for doing this request a long time ago:
  • DietPi-Software | phpBB: Updated to v3.3.0 which has PHP7.3 support, hence can be installed on all hardware models and distro versions.
  • DietPi-Software | Sonarr/Radarr/Lidarr: Enhanced install and uninstall steps. On reinstalls, the install directory is left unchanged now, suggesting to use the internal updater instead, which is generally safer and now does not require a manual service restart (see bug fix below). In case of a broken instance, the install directory /opt/<name> needs to be removed manually now, to have reinstalls downloading and installing the newest binaries.
  • DietPi-Software | Sonarr/Radarr/Lidarr: The service now runs with hardened permissions, by default blocking access to directories outside of /opt/<name>/mnt/var/log/<name> and /tmp. If writing to other directories is wanted, the service file needs to be edited, easiest with dietpi-services > “” > “Edit” and adding an additional ReadWritePaths=/path/to/custom/dir.
  • DietPi-Software | Chromium: Unlocked install on ARMv6 RPi models: RPi1/Zero/Zero W. Browsing performance will not be perfect, but for kiosk mode or light usage there are use cases. Many thanks to @kmplngj for requesting and testing: MichaIng/DietPi#3364
  • DietPi-Software | myMPD: Updated installer according to next upstream release v6.2.0. Many thanks to @jcorporation for informing us about the new version: MichaIng/DietPi#3382
  • DietPi-Software | MPD: Assured that UNIX domain socket and systemd unit for socket activation is present on Stretch systems. As well the obsolete cache directory symlinks in /var/lib/mpd will not be present anymore. Any custom scripts must use the absolute paths in /mnt/dietpi_userdata/.mpd_cache from now on.
  • DietPi-Software | Pi-hole: Enabled support for Pi-hole v5. Many thanks to @maartenlangeveld for reporting the required change: MichaIng/DietPi#3391
  • DietPi-Software | Shairport-Sync: Updated to new version 3.3.6, using self-compiled deb packages. Many thanks to @kmplngj for doing this request: MichaIng/DietPi#3216
  • DietPi-Software | HAProxy: Updated to newest stable upstream version 2.1.3 and the sysvinit service has been replaced with the officially provided systemd service. It will be reinstalled on all systems via - DietPi-Update, your config files will not be touched on any reinstall.
  • DietPi-Software | rTorrent: Further rework and update of the default config file. Many thanks to @bbsixzz for this contribution: MichaIng/DietPi#3332
