+ DietPi-Software | Node.js: Use fixed own installer fork for now: taaem/nodejs-linux-installer#11

+ CHANGELOG | DietPi-Drive_Manager: For NTFS mounts, the "big_files" mount option is now added by default, which reduces CPU load and by this may increase performance. Many thanks to @balexandrov for suggesting this enhancement: #3330 (comment)

+ DietPi-Drive_Manager | For NTFS mounts, add "big_files" option by default which prevents splitting write buffers into 4k chunks. This is generally seen as stable and is the default in new libfuse3: https://unix.stackexchange.com/a/544864

+ DietPi-Drive_Manager | Fix wrong NTFS option: big_files => big_writes

+ CHANGELOG | Fix wrong NTFS option: big_files => big_writes

+ DietPi-Obtain_HW_model | RPi: Remove special model names like alpha, beta or first ECN0001, but differentiate by type A and B only, to simplify statistics. The exact revision can always be estimated through the revision code, if it should become relevant in an individual case.
+ DietPi-Obtain_HW_model | RPi: Merge code for assigning identical hardware info
+ DietPi-Obtain_HW_model | RPi: Reduce the risk that A+ total memory is estimated wrong due to theoretical larger GPU memory split. 262144 KiB is really the upper boarder of what an 256M model can have, probably even 245760 (minus 16 MiB min GPU memory) would be thinkable or using vcgencmd to estimate the exact values (overkill?).
+ DietPi-Obtain_HW_model | Pinebook: We do not add and name suffix anymore as our image works on all revisions
+ DietPi-Survey_report | Add DietPi v6.32 support

+ DietPi-Services | Inform and offer to restart a service as well if "Edit" option was used

+ DietPi-Software | Python pip: We migrated this software selection to a Python3/pip3 install only, due to Python2 EOL in 2020/01. Where possible, dependant software selections have been migrated to Python3 builds, where not possible, Python2/pip2 is installed separately for now. We hope that most affected software titles will do Python3 releases soon, otherwise we will remove them form our portfolio, at latest in spring 2021. The strongest reason for this is that next Debian Bullseye (summer 2021) will not ship Python2 packages anymore.
+ DietPi-Software | SABnzbd: Migrated to a Python3-based install.
+ DietPi-Software | OctoPrint: On Debian Buster and up, migrated to a Python3-based install.
+ DietPi-Software | HTPC Manager: Resolved an issue where install failed due to missing build-essential dependency.
+ DietPi-Software | HTPC Manager: Resolved an issue where the internal updater failed due to missing git meta files.
+ DietPi-Software | EmonPi: Resolved a failing primary UART activation on install.
+ DietPi-Software | Mopidy: The official Buster repo now supports ARMv8/arm64 as well
+ DietPi-Software | "apt-cache show package" succeeds as well if package is listed as (optional) dependency/conflict/... by another package, hence is not a reliable measure. In case of python3-distutils on Stretch this causes an install failure if stretch-backports suite has been added, which contains a few packages that list python3-distutils as optional dependency aside of python3 << 3.6.something where Distutils was moved from stdlib into an own package. Allow to succeed if another package "provides" it, like php7.3-apcu provided by php-apcu or awk provided by mawk and gawk.
+ DietPi-Software | Disable all Python2-only titles for Bullseye, which does not serve Python2 packages anymore
+ DietPi-Software | Several uninstall enhancements

+ Coding | Replace bc decimal calculation with bash-internal printf conversion
+ Coding | Several minor enhancements around prior bc usage
+ DietPi-Cloudshell | Do not disable CPU scene on VM. Most values are "N/A" but usage bar and process count are shown correctly. Let user decide if it's worth it or not.

+ DietPi-Software | Cuberite: Skip obsolete move from "Server" sub dir to parent dir, as the download archive does not contain a top level dir anymore
+ DietPi-Software | Cuberite: Uninstall enhancements

+ DietPi-Software | Cuberite: Adjust download link as of: "Please DO NOT rely on the links below to represent the correct download location for Cuberite at all times, instead use the official download link: https://download.cuberite.org/linux-armhf-raspbian/Cuberite.tar.gz"
+ DietPi-Software | Cuberite: Do not run as "dietpi" group since Cuberite does not need to access (R/W) media or downloads and file servers/downloaders/media players do not need to access (R/W) Cuberite files. Lets keep using "dietpi" group for media, downloads and "regular" userdata only, not for software internal data, config and executables.

+ DietPi-Software | Assure that on reinstall all settings are preserved by not overwriting existing webadmin.ini. The new download archive is merged into the existing instance but does not include any variable data or configs.

+ DietPi-Software | Nginx: Use new 512 MiB default max upload size, as a compromise to keep performance up and SD card writes low on usual smaller uploads (pictures, documents, ...), while not risking RAM overload (with swap file enabled) in peek times. Uploads for larger files (disk images, video files, ...) usually require an external drive to hold PHP uploads, either through a large swap file or directly for all uploads.

+ DietPi-Software | PHP: Move session files to tmpfs outside of /tmp and /var/tmp to /run/php_sessions by default
+ DietPi-Software | PHP: Move tmp upload dir back to tmpfs but limit default max upload size, discuss and find balance between performance, disk (SD card) writes and RAM over-usage.
+ DietPi-Software | PHP: Assure that opcache.interned_strings_buffer is never larger than half of opcache.memory_consumption: #2293
+ DietPi-Software | ownCloud/Nextcloud: On <1 GiB devices assure at least 512 MiB swap space are available to stand 512 MiB file uploads + increased PHP cache and session file usage

+ DietPi-Imager | Syntax fixes

+ DietPi-Imager | e2fsck: need terminal for interactive repairs

+ DietPi-Imager | After interactive image content edits, give the system 1 second before unmounting, to avoid "mount is busy"

+ DietPi-Software | NFS Server: rpcbind is a strict dependency of nfs-kernel-server
+ DietPi-Software | NFS Server: Write dietpi_userdata export into own file /etc/exports.d/dietpi.exports to not override existing /etc/exports on (re)install

+ DietPi-Software | Tiny

+ DietPi-Patch | Resolve an issue where on pre-v6.23 system the PHP upgrade from v7.0/7.1 to v7.2/7.3 did not work as expected.

+ DietPi-Services | Do not control PHP versions which are not supported anymore

+ CHANGELOG | PHP: Resolved an issue where on pre-v6.23 system the PHP upgrade from v7.0/7.1 to v7.2/7.3 did not work as expected.

+ DietPi-Set_hardware | Apply Bluetooth via UART (hciuart) only on RPi models with onboard Bluetooth, hence if it IS indeed attached via UART. Respect this as well when asking to disable serial console on ttyAMA0 when enabling Bluetooth.
+ DietPi-Set_hardware | Start to use function return codes as script exit code, WIP
+ DietPi-Set_hardware | Try to reduce doubled or leading and trailing spaces when adding/removing settings to set of settings on a single line, like /boot/cmdline.txt on RPi.
+ DietPi-Set_hardware | Minor coding

+ DietPi-Software | Pi-hole: Skip the installers new internal supported OS check to enable us testing Debian Bullseye. A warning is still print and we do not offer Debian testing images as stable, so this is to make our internal testing easier only.

+ DietPi-Benchmark | Resolve error on file system benchmark due to float in bash arithmetic: #3672

+ CHANGELOG | DietPi-Benchmark: Resolved an issue where file system benchmarks failed

+ DietPi-Benchmark | Simplify file system benchmark result conversion since awk/mawk can do all reads an calculations + correctly rounded integer output in one step. Keep that in mind when using mawk anyway to scrape outputs.
+ DietPi-Benchmark | Do not use conv=fdatasync for file system read benchmark, which is an invalid option for of=/dev/null. File system cache has been flushed before, which is all that we need to assure an unbuffered read.

+ DietPi-Software | Xfce assure that xfwm4 composition manager is used as xcompmgr breaks the appearance settings and leads to black boarders around some windows when using option "-a": #3665

+ DietPi-Start_Kodi: Only force new xcompmgr when it is actually available/installed

+ CHANGELOG | Xfce: Resolved an issue where the the install and autostart of xcompmgr composition manager broke the xfwm4 internal one

+ CHANGELOG | DietPi-Config: Resolved an issue where RPi onboard Bluetooth is attempted to be enabled on RPi models without onboard Bluetooth

+ DietPi-Software | When passing wildcard asterisk as command argument, quite it to avoid file globbing
+ DietPi-Software | OpenSSH: Do not purge the client together with the server. Both have dedicated IDs and can be selected for uninstall separately. Likely it is a relic since the client is automatically installed with the server as package dependency. The openssh-client package needs to be installed/marked separately during server install to not get autoremoved on uninstall and for transparency.
+ DietPi-Software | DietPi-RAMlog: Remove obsolete dependency of uninstall server on DietPi-RAMdisk
+ DietPi-Software | Minor code structure and wording enhancements

+ DietPi-Software | When changing fileserver or logging choices, run uninstall loop after installs only if any previous choice actually needs to be uninstalled
+ DietPi-Software | On uninstall confirmation prompt, add info that uninstall usually means purging or any related data and configs. If repair or update of software is wanted, reinstall should be used. Add software IDs to list so users know exactly which command to call from terminal, until be build it into GUI.
+ DietPi-Software | Reduce large if-then-else blocks by using "return" where possible

+ CHANGELOG | DietPi-Software:  On the uninstall information prompt, the info has been added that uninstalling usually means that related userdata and configs are purged as well

+ DietPi-Software | Minor text formatting to better outline message

+ DietPi-Software | qBittorrent: Move log file dir to /var/log/qbittorrent for new installs
+ DietPi-Software | qBittorrent: Do not pass web UI port via binary call since it is contained in the config file but overridden by command option.

+ DietPi-PREP | Do basic APT configuration before calling it the first time via new config file scheme
+ DietPi-PREP | Force re-adding and replacement of missing and new APT package config files during PREP run, to assure consistent up-to-date configs, especially relevant for security-related things like ca-certificates and similar. Revert to DietPi default afterwards, where modified and missing configs are silently ignored/accepted, matching as well Debian default as long as a default choice is available (I never saw it differently) to allow unattended package installs/upgrades and review new config files at a later time. Cleanup obsolete config files (with .dpkg-old/new/dist suffix) after all installs have been done.
+ DietPi-PREP | Remove apt-utils from dependencies. It is used by debconf for package pre-configuration, but G_AGI includes "DEBIAN_FRONTEND=noninteractive", hence any config and pre-config step is skipped anyway, but defaults are applied, which is fine in very most cases. Else we do "dpkg-reconfigure" to recall debconf inputs. Without apt-utils, debconf is not able to extract templates prior to install, hence when installing/upgrading packages interactively/manually, debconf input is done when the individual package is about to be installed instead of having all inputs prior to all installs. Leave choice to user whether this is required or not, debconf prints a meaningful message about missing apt-utils.
+ APT | Merge all DietPi APT configs into a single config file. Apply the following prefix/priority scheme: "97" for base configs, "98" for additions/overrides from software installs or dietpi-config choices, leaving "99" free for end user overrides.
+ DietPi-Patch | APT configs have been merged into a single file, contained in update archive, hence remove obsolete files

+ DietPi-Software | Nextcloud: Add Argon2 hashing tweaks. Use all available CPU threads for now, which radically reduces hashing time one multi-core SBCs, wait with memory cost and time cost until getting some clarification, especially since those are security relevant and defaults do not break anything: nextcloud/server#19023 (comment)

+ DietPi-Software | Pi-hole: Assure Referrer-Policy is not set to "no-referrer" since HTTP_ORIGIN != null is required for CORS check. In case it's set, replace by second strict policy "same-origin": #3675

+ CHANGELOG | Pi-hole: Resolved an issue with Apache webserver, where CORS check failed if the Referrer-Policy header has been set to "no-referrer". If this is the case, the Pi-hole Apache config now sets it to the second strict "same-origin", which does not break the Pi-hole admin panel. Many thanks to @Phil1988 for reporting this issue: #3675

+ CHANGELOG | qBittorrent: Resolved an issue where setting the web UI port via config file or UI is overridden by the service file command option. Many thanks to @linxiaopi for reporting this issue: #3660

+ DietPi-Software | Remove Rsyslog as dependency. CloudPrint until Debian Bullseye was the only left case and that Google service is shutdown in this years fall. Since it generally does not conflict with DietPi-RAMlog (probably practically because of the log files 1h lifetime), allow packages (like cloudprint) to pull it as dependency and on uninstall (logging choice) do not purge but instead mark for autoremoval only. The install option itself, however is only left for logging choice, which will by times be replaced by persistent systemd-journald logs to /var/log/journal.

By @fpetru

+ APT | Keep indexes compressed by default to reduce disk usage and writes

+ APT | Disable source package cache by default which most users will never use
+ APT | Store lists xz-compressed. The default is to download them xz-compressed (as shipped by Debian and Raspbian) to lists/partial/, uncompress and copy to lists/ which leads to ~120 MiB disk writes for ~8.5 MiB xz-compressed and 45 MiB uncompressed list files. Using GzipIndexes only, leads to lz4 compression, since it has the lowest compression "cost" in APT internal default config. This leads to ~60 MiB writes for download, re-compress and copy. Forcing xz-compression storage not only leads to lowest disk usage (highest compression ratio) but also skips the un-/re-compression step and related additional file creation/writes. But it must be noted that this leads to significantly slower list reading during "apt-get update" and, if (binary package) cache is disabled, during "apt upgrade/install" as well. We have to collect some user feedback to see if this is acceptable, especially on slow devices like RPi1 and Zero. However especially on those, when running OS on SD card, reducing disk writes is a major aspect to increase SD card lifetime and reduce the related risk of data loss. Spending 1-2 minutes longer during dietpi-update and dietpi-software runs might be acceptable.

+ DietPi-PREP | Align with new /etc/apt/apt.conf.d/97dietpi

+ DietPi-Software | InfluxDB/Grafana: Install repo key as dedicated file
+ DietPi-Software | Minor uninstall enhancements

+ DietPi-Survey_report | Add transparent favicon and theme tags for all OS/browser variants

+ DietPi-Login | $PS1 is highly expected but not required for an interactive shell, check for input tty and most reliable bash $- flag only
+ DietPi-Login | Always set LANG as well since 3rd party software/scripts might derive the current locale from it even that LC_ALL overrides it.
+ DietPi-Login | Minor coding, less and faster external command calls

+ DietPi-Login | Add /etc/bashrc.d/readme.txt as little /etc/bashrc.d/ documentation

+ DietPi-PREP | systemd-logind is a static unit, do not attempt to disable it
+ DietPi-PREP | Set console charmap to UTF-8 which can be wrong, e.g. when selecting a non-UTF-8 locale during Debian installer
+ DietPi-PREP | Fix grub debconf install device selection: #3700

+ DietPi-Imager | Minor consistency

+ DietPi-Set_swapfile | Do not attempt to remount /tmp if it is not setup as separate mount (tmpfs)
+ DietPi-Set_swapfile | Do not print current swap file info on empty input, instead use input > dietpi.txt > current > default in this priority order to apply for any missing argument. E.g. /proc/swaps (or htop) is a much more reliable source to get active swap file then relying on the dietpi.txt entry.
+ DietPi-Set_swapfile | Remove BeagleBone Black special handling since 4 GiB still allow a small swap file and rootfs could be placed on an external drive.
+ DietPi-Set_swapfile | Always remove all existing swap files. We already disabled and removed all from fstab, but in theory if multiple existed before or those were stored at a different location, the files would have been left in place.
+ DietPi-Set_swapfile | Coding and verbosity enhancements

+ DietPi-PREP | Mount tmpfs to /tmp if it is not yet a dedicated mount to work in it and reduce disk I/O and speed up download and unpacking

+ CHANGELOG | DietPi-Set_swapfile: Running the script without input arguments does not print the current swap file location and size anymore but will apply the settings stored in dietpi.txt, refresh the current swap file or apply defaults as fallback.

+ DietPi-Set_hardware | enableipv6: Do not write files (sed -i) if the setting is not contained
+ DietPi-Set_hardware | enableipv6: Always write to symlink targets instead of overwriting the symlink with the file (sed -i): #3003 (comment)

+ DietPi-Patch | Recreate /etc/sysctl.d/99-sysctl.conf -> ../sysctl.conf symlink hopefully the last time, as we identified the bug in our own code: #3003 (comment)

+ CHANGELOG | Resolved an issue where enabling or disabling IPv6 removed the expected symlink at /etc/sysctl.d/99-sysctl.conf with its actual target file

+ DietPi-Survey_report | Add Matomo code

+ DietPi-Boot | Do log to file but to journal instead and don't print $(date) since this doubles the journal timestamps
+ DietPi-FirstBoot | Log to disk directly
+ DietPi-PreBoot | Do log to file but to journal instead
+ DietPi-RAMlog | Fix error log to file
+ DietPi-RAMlog | We want to keep file logging since it is important to know, in case of failure, whether on shutdown /var/log/ has been stored to disc correctly. However, only the last shutdown is relevant in case, hence do not append but overwrite log on shutdown, append on startup.
+ DietPi-RAMlog | Sort after boot.mount. This should be included in local-fs.target, but as we're already failsafe with -.mount (root), let's be consequent then.
+ DietPi-PostBoot | No boot logs are to be moved to disk anymore
+ DietPi-PostBoot | Add exit code handling and error message for user scripts and service starts
+ DietPi-Backup | Minor output enhancements
+ DietPi-Create_MySQL_DB | Minor output enhancements
+ DietPi-Globals | Make G_DIETPI-NOTIFY compatible with journal and file logging by only using ANSI escape sequences if the process is connected to a terminal
+ DietPi-Globals | When calling "G_DIETPI-NOTIFY -1" the "|" which separates message and result is added function internally now
+ DietPi-Set_userdata | Minor output enhancements
+ Re-test shellcheck source-path
+ DietPi-Globals | G_TREESIZE: Handle "bytes" sizes and unit as well and do not require root. If "du" tries to access dirs without read permissions, it prints meaningful error messages to STDERR, not processed by sort + mawk, so now one sees the errors (in case) and the treesize for all permitted dirs.
+ DietPi-Globals | G_CHECK_FREESPACE: Check for valid du output as well when only printing available free space. This allows the feature to be used safely in scripts and will return a non-zero exit code if either the input path does not exist, cannot be read, df is broken or similar.
+ DietPi-Globals | Various output and failsafe coding enhancements

+ shellcheck | Disable SC2155, as we intentionally declare and assign combined and check for valid result based on the value afterwards, which is safer, e.g. the command substitution succeeds but prints garbage or simply a result that we need to handle as error for the originating task.
+ shellcheck | Disable SC2188, as we intentionally do empty redirects to create and touch files without adding content. Adding any command like "touch", "echo", "true" or ":" is a marginal but measurable overhead, hence we skip it. If this would be due to a coding fault, e.g. redirect accidentally moved to newline, this would be pretty fast recognised through tests as additional console print and missing file content.

+ DietPi-Software | Syntax

+ DietPi-Services | Minor coding

+ NanoPi NEO3 | Add initial support
