+# 2.69.0
+
+Changes:
+* ImageMagick is no longer used for image logos on Windows, macOS and Android, and has been replaced by the platform image frameworks (WIC on Windows, ImageIO on macOS, AImageDecoder on Android). (Logo)
+    * An image logo needs Android 11 (API 30), the release that introduced the platform image decoder, and is reported as an error on Android 10 and older.
+* ImageMagick 6 support is deprecated. It is kept only for old Debian and Ubuntu releases that don't have ImageMagick 7 available, and is intended to be removed in a future release. Users are encouraged to upgrade to ImageMagick 7 when possible.
+* The `--logo-recache` option has been replaced by `--logo-cache <bool|regen>`, and the `logo.recache` JSON property has been renamed to `logo.cache`. (Logo)
+    * `--logo-cache true` (the default) reuses a cached rendering when it is valid, and writes it back on a cache miss; `false` ignores the image logo cache completely, reading nothing from it and writing nothing to it; `regen` does what `--logo-recache true` used to do. `logo.cache` accepts a boolean, or the string `"regen"`.
+* The `waitTime` option of `DiskIO` and `NetIO` now defaults to `250` ms instead of `500`. (DiskIO / NetIO)
+    * The byte counters are maintained by the kernel as I/O happens, so a shorter sampling window still yields an accurate rate, and both modules now finish about 250 ms sooner. The two modules wait concurrently, so enabling both does not cost twice the wait time.
+* The `waitTime` option of `Top` now defaults to `250` ms instead of `500`. (Top)
+    * The operating system accounts process CPU time in fixed steps, so a window longer than roughly 150 ms does not visibly improve the reported percentages. The module now finishes about 250 ms sooner.
+
+Features:
+* Improved image logo support
+    * Backend rewritten
+        * Added a native image decoding backend on Windows (WIC), macOS (ImageIO) and Android (AImageDecoder).
+        * Added an embedded libsixel encoder, used to produce sixel output on Windows, macOS and Android. It is reported by `fastfetch --list-features` as "Embedded sixel".
+        * Enabled chafa image output on Windows, macOS and Android independently of ImageMagick.
+        * As a result, `fastfetch --sixel X:\path\to\image` now works out of the box on Windows Terminal.
+    * Image logo cache entries are now validated against the modification time of the source image, so editing an image logo in place invalidates its cached rendering. (Logo)
+        * Cache entries written by older versions are not reused, as they carry no modification time.
+    * Image logos can now be animated when the terminal and the image protocol support it. (Logo)
+        * `--logo-animation-frame <0>` (`logo.animationFrame: 0` in the JSON config) plays a GIF or APNG. Only the `kitty` image protocol can play an animation; the frames are decoded and composed by fastfetch, so no external program is involved.
+        * `--logo-animation-frame <N>` renders the Nth frame as a still image, and negative values count back from the end, so `-1` is the last frame. This works for the `sixel`, `kitty` and `chafa` logo types. Note that negative values can only be given in the JSON config, as the command line parser reads a leading `-` as another option.
+        * The default is `1`, which renders a still image, so nothing changes for anyone who does not opt in. The frames come from the platform image framework (WIC on Windows, ImageIO on macOS, AImageDecoder on Android, ImageMagick 7 on Linux); a single-frame GIF falls back to a still image.
+        * On Android an animation needs Android 12 (API 31), and the repeat count is not available there, so an animation is reported as looping forever. A build with no image decoder, or one built with ImageMagick 6, reports an error instead of silently showing a still image.
+        * A terminal that supports the kitty graphics protocol but not its animation frames, such as Konsole, shows the first frame.
+    * Added the CMake option `ENABLE_IMAGE_LOGO`, which defaults to `ON`. Configure with `-DENABLE_IMAGE_LOGO=OFF` to build fastfetch without any image logo support. (Logo)
+        * Image logos are the only consumer of ImageMagick, chafa, and the embedded libsixel encoder, so none of the three is searched for at configure time, and no image decoding sources are compiled in. This is intended only to reduce binary size on embedded systems (such as OpenWrt).
+        * The `sixel`, `kitty`, `kitty-direct`, `kitty-icat`, `iterm` and `chafa` logo types are rejected with an error, both on the command line and in the JSON config, and the `auto` logo type never tries an image.
+        * `--logo-type raw` keeps working: it passes a pre-rendered byte stream through unchanged and needs no decoder, so a logo can still be displayed by converting the image externally.
+* Added CPU name and frequency detection support on SPARC. (CPU, Linux)
+* Added package detection support for CRUX. (Packages, Linux)
+    * Exposed in custom format as `{crux}`.
+* Improved Android ROM detection (DE, Android)
+    * Added support for HarmonyOS, HarmonyOS NEXT, Flyme, JOYUI, SmartisanOS, realme UI, HydrogenOS, ZUI, ZUXOS, MyOS, NebulaAIOS, ObricUI, MiFavor, LineageOS, PixelExperience, EUI and 360 UI.
+    * Added support for MagicUI 3.x, which stores a bare version number instead of a `MagicUI_x.y.z` string.
+    * Added Samsung OneUI support (#2541)
+    * It is read from system properties, so no particular Android version is required. This is mostly untested due to lack of available devices running these ROMs. Please report any issues you encounter.
+* Improved Camera detection on Android (Camera, Android)
+    * The camera list is now read from the camera2 NDK instead of `termux-api CameraInfo`, so the Termux:API app is no longer required and no subprocess is spawned.
+    * This needs Android 7.0 (API 24), which is where the camera2 NDK was introduced.
+* Improved Battery detection on Android (Battery, Android)
+    * The charge level and charging state are now read from the battery properties service over `/dev/binder` instead of `termux-api BatteryStatus`, so the Termux:API app is no longer required and no subprocess is spawned.
+    * The service interface changed in Android 10, and the right request is picked at run time, so every Android release is covered.
+    * Battery temperature, cycle count, manufacturer, model name, serial number and manufacture date need the `BATTERY_STATS` permission, which an app cannot obtain, so an app no longer reports them.
+    * Running as `adb shell` or as root, `dumpsys battery` is used, which also reports the battery temperature and technology, and reports a battery that has reached the critical level as such. An app can read none of the three.
+* Improved Display detection on Android (Display, Android)
+    * The displays are now read from the display service instead of a vendor property that only some Xiaomi devices set. The preferred mode, the physical size, the rotation, the manufacture date and the display id are now reported as well.
+    * This needs Android 13 (API 33). On Android 12 and older only that vendor property is available to an app, and a device that does not set it reports no display.
+    * Running as `adb shell` or as root, `dumpsys display` is used as well, which is what covers Android 12 and older.
+    * The refresh rate is now the rate of the active display mode, and the HDR capability is read from the display itself, for every display rather than only for the built-in one.
+* Improved WiFi detection on Android (Wifi, Android)
+    * The connection details are now read from the WiFi service over `/dev/binder` instead of `termux-api WifiConnectionInfo`, so no subprocess is spawned.
+    * The Termux:API app is still required, though. It is what carries the WiFi permission that the Termux app does not request itself, so uninstalling it turns this module off.
+    * A location permission is required as well, and Termux:API is what carries that one too. The WiFi service withholds the SSID and the BSSID from an app that does not hold one, and hands both over once it is granted; until then the signal, the rates, the frequency, the Wi-Fi standard and the security type are reported as usual, and the two names are reported as `<redacted>`. The grant has to be for all the time rather than only while the app is in use, as the service withholds the two names from an app that is not in the foreground either -- which is the state a run over `ssh` is in.
+    * The interface name and its state, the connection state, the Wi-Fi standard and the security type are now reported as well.
+    * The security type is reported from Android 12 on. The reply Android 11 sends ends before that field, so the `security` field stays empty there.
+    * This needs Android 11 (API 30), the release that moved the Wi-Fi framework into an APEX. There is no fallback, so Android 10 and older report an error instead.
+    * WiFi detection on Android is experimental. The reply the WiFi service hands an app drifts between Android releases and between vendors, and what it contains also depends on the permissions the calling app holds, so a device can report less than its connection has. Please report anything that looks wrong or missing.
+* Improved COSMIC detection (DE / WM, Linux)
+    * The version is now read from the `COSMIC_VERSION` environment variable when it is set.
+* Improved accuracy and performance of process name detection in the Top module. (Top, macOS)
+* Improved Packages detection on Windows (Packages, Windows)
+    * `winget` is now detected by default, instead of requiring a build-time opt-in, and the source agreements are accepted non-interactively on a machine that has never accepted them. Opt out by setting `packages.disabled` to `["winget"]`, or by configuring with `cmake -DPACKAGES_DISABLE_WINGET=ON`.
+    * The count reports the packages the `winget` source knows about, which is not limited to the packages `winget` itself installed. Microsoft Store apps are no longer counted.
+    * `winget list` takes about 1.5 seconds, so its result is cached. The cache is refreshed when a program is installed or removed, not on a timer, so only the first run after such a change is slow.
+* Improved Wallpaper detection on macOS Sonoma and later (#2559, Wallpaper, macOS)
+    * The image path is now also extracted from the `Configuration` field of the wallpaper plist, and the `NSWorkspace` fallback is used only as a last resort.
+* Removed the `kvm` dependency on OpenBSD by using `sysctl` directly. (General, OpenBSD)
+* Modules that were selected on the command line via `--structure` / `-s` now honor module options configured in the JSON config. (CommandOption)
+* Improved reliability of fastfetch's built-in HTTP client. (PublicIP, Weather)
+    * It now supports custom ports and can properly handle chunked transfer encoding. It is designed for minimal resource usage and fast performance, and does not support full HTTP features like HTTPS; the `Command` module with `curl` can be used for those.
+* Added Umbriel wayland compositor version detection (WM, Linux)
+* Improved the player name detection on Windows to show the name Windows shows for it. (Player, Windows)
+    * An unpackaged player such as Chrome is now reported as `Google Chrome` instead of `Chrome`.

+* Added module key localization support. (General)
+    * Added a new option `--key-language <?lang>` (`display.key.language: "<?lang>"` in JSON config). When left empty, it defaults to the system locale.
+    * See `fastfetch -h key-language` for all supported languages.
+    * Exposed in custom key format as `{module-name}`.
+* Improved Wi-Fi module
+    * Added Wifi channel width detection, exposed via `{channel-width}` in custom format (reports 0 when not supported).

+* Fixed the fast path of ash version detection. (Shell)
+* Fixed memory usage detection support on x86-32 FreeBSD (Memory, FreeBSD)
+    * Note: Although 32-bit systems are still supported, they are deprecated and barely tested. Users are encouraged to upgrade to 64-bit systems.
+* Some internal cleanups and optimizations.
+* Attempted to fix potential issues on big-endian systems
+    * Not tested due to lack of access to big-endian hardware.

+# 2.67.1
+
+Bugfixes:
+* Fixed a `Symbol not found` error when running on macOS 10.15. (#2499, Codec, macOS)
+* Fixed Alacritty font size never being parsed from the TOML config. (#2501, TerminalFont)
+* Fixed bright colors incorrectly being active when the terminal uses a light theme. (#2509, Display)
+* Fixed Ghostty terminal font detection (TerminalFont)
+    * Now tries to load the config with the `.ghostty` extension. (#2500)
+    * Fixed `font-family` fallback order. (#2510)
+* Some internal cleanups and optimizations.
+
+Features:
+* Added a C23 compiler check so the build process gracefully exits during CMake configuration if the compiler is unsupported. (CMake)
+* Added compatibility workarounds for Apple Clang 16 to fix building on macOS 14. (CMake, macOS)
+* Reported real Android version codenames (e.g., "Baklava", "Vanilla Ice Cream") instead of "REL". (OS, Android)
+* Added Loadavg detection support on Haiku R1B6. (Loadavg, Haiku)
+* Enabled image logo support in the Zellij terminal multiplexer. (#2507, Logo)
+* Improved Locale detection on Windows (Locale, Windows)
+    * Now respects `LC_ALL` and `LANG` environment variables if set for better compatibility with MSYS2/cygwin.
+    * Appends the active system Code Page (e.g., `.UTF-8` or `.Windows-1252`) to the default system locale fallback.
+
+# 2.67.0
+
+Changes:
+* The minimum supported compiler version has been raised to GCC 13 (released on 2023-04-26) and Clang 16 (released on 2023-03-17) to accommodate the new C23 syntax used throughout the codebase. (General)
+    * As a result, building from source in Debian 12 (which only ships GCC 12 by default) is no longer supported. Users must upgrade their compiler or use the prebuilt binaries from the GitHub releases page.
+* The `general.preRun` option has been removed due to security concerns. (General)
+    * Users who relied on this option to run a command before printing output will need to move that logic to an external wrapper.
+* The `{status}` placeholder in Battery custom format is now an array type instead of a single comma-separated string. (Battery)
+    * This is a breaking change for users who print `{status}` in Lua scripts. They can use `table.concat(...)` to join the array into a single string if needed.
+* The `--gen-config-*` flags (`--gen-config-full`, `--gen-config-force`, `--gen-config-full-force`) have been removed and their functions have been merged into `--gen-config`. (Global)
+    * See features below.
+
+Features:
+* `--gen-config` now opens an interactive configuration TUI to make generating config files easier.
+    * It falls back to non-interactive generation when `$NO_COLOR` is set or when stdin/stdout is not a TTY. This behavior can also be used to disable the interactive mode.
+* Added an experimental [WebUI](https://fastfetch-cli.github.io/fastfetch-config/) ([separate project](https://github.com/fastfetch-cli/fastfetch-config)) for generating and editing configs.
+* Added `-w`/`--watch` as a seconds-based alias for `--dynamic-interval`, defaulting to 1 second when no value is provided. (#2478, Watch)
+* Added InitSystem detection on Windows, reporting the first userland process (`smss.exe`). (InitSystem, Windows)
+* Added CPU and GPU temperature detection support for Apple M5 series chips. (CPU / GPU, macOS)
+* Reported `Basic` as the Windows theme when DWM is disabled. (Theme, Windows)
+* Improved Ghostty terminal font detection performance. (#2122, TerminalFont)
+    * It now parses Ghostty directly instead of running `ghostty +show-config`.
+* Added support for a wider range of TOML config syntaxes used by Alacritty. (#2456, TerminalFont)
+
+Bugfixes:
+* Fixed a potential fish version detection error. (Shell, Linux)
+* Fixed incorrect resolution reporting when a monitor advertises multiple preferred modes. (#2481, Display, Linux)
+* Fixed connected monitors being missed when Wayland output events arrive late. (#2451, Display, Linux)

+* Fixed Ubuntu Studio Core detection. (OS, Linux)
+* Relaxed the HTTP response check so that both `HTTP/1.0` and `HTTP/1.1` responses are accepted when fetching data over the network. (PublicIP / Weather)
+* Various internal cleanups and optimizations:
+    * Fixed multiple memory leaks (Separator, Camera, Codec, Display).
+    * Added integer overflow checks to the string buffer implementation.
+    * Various code cleanups and compiler warning fixes.
+
+Logos:
+* Removed Hypros, MagpieOS, Furreto, EmperorOS and Magix

+
+# 2.65.2
+
+Changes:
+* Memory usage calculations now exclude the ZFS ARC cache on Linux, FreeBSD, NetBSD, and SunOS. (#1995 / #2418, Memory)
+    * This prevents the Memory module from reporting artificially high memory usage on systems with the ZFS kmod enabled.
+
+Bugfixes:
+* The GPU module no longer pings sleeping dedicated GPUs on dual-GPU laptops. (#2419, GPU)
+    * As a result, PCIe link speed detection (introduced in v2.65.0) is now only enabled in `driverSpecific` mode.
+* Fixed a crash when detecting hardware codec support with the `amdgpu` driver on Linux. (#2419, Codec, Linux)
+
+Logos:
+* Updated CachyOS_small; fixed CachyOS logo colors to match the official logo better
+* Added Turkish
+
+# 2.65.1
+
+No changes
+
+# 2.65.0
+
+Changes:
+* `display.disableLinewrap` now defaults to `false`.
+    * This allows long lines to wrap instead of being truncated, preventing confusion for new users.
+    * Wrapped lines may overlap with the image logo. Users who prefer the old behavior can set `display.disableLinewrap: true` in their config file or use `--disable-linewrap true` on the command line.
+* Reorders package manager variables in custom format strings, moving aggregate variables (e.g., `all`, `brew-all`, `flatpak-all`) to the end. (Packages)
+    * This is a breaking change for users relying on numeric placeholders (e.g., `{1}`). Numeric placeholders are a long-deprecated feature; named placeholders (e.g., `{pacman}`) are always preferred and future-proof.
+* Enables `showPeCoreCount` by default to better display hybrid-architecture core counts. (CPU)
+* No longer accepts `chafa` options in config files if `chafa` support was disabled at compile time. (Logo)
+    * This may affect users who generated their config files using `fastfetch --gen-full-config`. To resolve this, simply remove the `chafa` section from the config file.
+
+Features:
+* Adds detection for CPU code names (e.g., "Alder Lake", "Zen 4") and manufacturing technologies (e.g., "Intel 7", "TSMC N4") on x86 processors. (#1501, CPU, X86)
+    * These can be used in custom formats via `{code-name}` and `{technology}`.
+* Adds PCIe link speed detection (current and max generation & lanes) for GPUs on Linux and Windows.
+    * These can be used in custom formats via `{pcie-max-speed}` and `{pcie-curr-speed}`.
+* Adds HDR display detection via the `wp-color-management-v1` Wayland protocol. (#2356, Display, Linux)
+    * Previously, HDR detection was only supported on KDE Plasma.
+* Adds the `egl-ext` detection method, which uses `EGL_EXT_device_enumeration` for GPU enumeration. (GPU)
+* Adds terminal version and font detection for `kmscon`. (#2393, Terminal / TerminalFont, Linux)
+* Adds the currently-in-beta code name "Golden Gate" for macOS 27. (OS, macOS)
+* Adds WPA version detection on FreeBSD. (Wifi, FreeBSD)
+* Adds package manager support for `porg` (#2405) and `install-release` (#2342). (Packages, Linux)
+* Adds Weston version detection. (WM, Linux)
+* Improves the core type (P-Core/E-Core) fetching mechanism on Windows by using `EfficiencyClass` instead of legacy frequency inference. (CPU, Windows)
+* Improves display detection compatibility with KDE 6.7. (Display, Linux)
+* Improves display serial number detection, now preferring alphanumeric serial numbers when available. (Display)
+    * This can be used in custom formats via `{serial}`.
+* Improves the performance of `emerge` package manager detection. (#2406, Packages, Linux)
+* Improves error messages for config file parsing errors.
+* Improves reliability of the `Codec` module on Linux (Codec, Linux)
+    * Adds `va-x11` backend for VA-API and VDPAU, which is used if `va-drm` backend fails to initialize.
+    * Fixes an issue where the Codec module incorrectly reports no results when the `codec.showType` option is set.
+
+Bugfixes:
+* Fixes physical core detection on non-x86 architectures and simplifies the frequency detection code. (CPU, Linux)
+* Fixes console mode and output code page initialization issues when running `fastfetch` in `Conhost`. (#2383, Windows)
+* Fixes public IP detection randomly failing on Linux. (#2401, PublicIP, Linux)

+
+# 2.64.1
+
+Features:
+* Adds a CMake option `-DPACKAGES_REMOVE_DISABLED` to remove detection code of disabled packages (`-DPACKAGES_DISABLE_<PACKAGE_NAME>`) for slightly smaller binary size (Packages)
+
+Bugfixes:
+* Fixes compatibility issues with Lua 5.3
+* Avoid possible infinite recursion in `encode_json` when encoding deeply nested tables or circular references
+* Fixes compilation issues when building with old macOS SDKs
+
+# 2.64.0
+
+New **optional build** dependencies:
+* [`libva`](https://github.com/intel/libva) and [`libvdpau`](https://www.freedesktop.org/wiki/Software/VDPAU) for the new `Codec` module.
+* [Lua 5.3 to 5.5](https://www.lua.org/) for Lua scripting support, or [QuickJS](https://github.com/quickjs-ng/quickjs) v0.15.0 or newer for JavaScript scripting support.
+
+Features:
+* Adds `Codec` module support for Windows, macOS, Linux, and Android for hardware-accelerated video codec detection (Codec)
+    * Backends used (results may vary depending on the backend due to driver differences):
+        * Linux and BSD: VA-API (default) and VDPAU (fallback for NVIDIA). Fastfetch must be built with `libva` and `libvdpau` support to enable these backends.
+        * Windows: D3D12VA (Windows 11) and D3D11VA+MFT (Windows 10 or older)
+        * macOS: VideoToolbox
+        * Android: AMediaCodec
+        * Common: Vulkan Video (disabled by default; can be enabled with `"useVulkan": true`)
+    * By default, both encoders and decoders are reported. If no codecs are detected for a given type, `None` is reported. This behavior can be configured using the `"showType": "encoder|decoder"` option.
+* Adds experimental Lua script support for custom formats (Global)
+    * Basic usage (using `Title` as an example): `{ "type": "title", "format": "lua:return string.format('Hello %s@%s', (...).userName, (...).hostName)" }`. The `lua:` prefix indicates a Lua script. A `return` statement is required to pass the final result back to the fastfetch module; otherwise, `nil` is returned implicitly and the entire module output is skipped.
+    * Parameters are passed via variable arguments `(...)`. Users can assign them to named variables for better readability. For example: `lua:local args = ...; string.format('Hello %s@%s', args.userName, args.hostName)`.
+    * The Lua interpreter instance is shared across all modules. This allows users to store and manipulate data across modules. For example:
+        * `{ "type": "shell", "format": "lua:shell = ..." } // Note: no "return" here`
+        * `{ "type": "terminal", "format": "lua:return shell.prettyName .. ' in ' .. (...).prettyName" } // This will print the detected shell and terminal names`
+    * A `json_encode(table, is_pretty)` function has been added to the Lua API for easier debugging. For example, `lua:return json_encode(...)` will print all available variables and their values in JSON format.
+    * Supported Lua versions: Lua 5.3 to 5.5 (Lua 5.1 and LuaJIT are not supported). The Lua version is auto-detected at build time. Once built, users can check the configured Lua version using `fastfetch --list-features`.
+* Adds experimental QuickJS script support for custom formats as an alternative to Lua (Global)
+    * Basic usage: `{ "type": "title", "format": "qjs:`Hello ${this.userName}@${this.hostName}`" }`. The `qjs:` prefix indicates a JavaScript script. No `return` statement is needed; the final result is simply the evaluated value of the script.
+    * Parameters are passed via the `this` object. Usage is mostly the same as Lua, but using JavaScript syntax.
+    * Requires [quickjs-ng v0.15.0](https://github.com/quickjs-ng/quickjs/releases/tag/v0.15.0) or newer.
+* Adds CMake options `-DMODULE_DISABLE_<MODULE_NAME>=ON` to disable modules at compile time for a smaller binary size
+    * Use `cmake -L . | grep MODULE_DISABLE_` to list all available options.
+    * These options rely on LTO for dead code elimination (`-DCMAKE_BUILD_TYPE=Release` should enable LTO by default).
+* Adds the ability to remove unneeded ASCII logos without modifying the fastfetch source code, further reducing binary size
+    * Simply remove the corresponding logo file from the logo directory (`src/logo/ascii/[a-z]/*`) and re-run `cmake`.
+* Improves string manipulation specifiers in custom formats
+    * They are now ANSI escape-aware and work correctly with colored output (e.g., percentages with `num-color`) (#2364). Limitations:
+        * They are still not wide-character aware and treat CJK and emoji characters as raw bytes.
+        * Escape sequences in the middle of strings are not supported.
+    * A new `|` specifier has been added to center strings. For example, `{user-name|20}` will center the username in a 20-character-wide field.
+* Adds preliminary `Bootmgr`, `Brightness`, and `WMTheme` detection support for Haiku (#2358, Haiku)
+* Adds `Wallpaper` and `WMTheme` detection support for the COSMIC desktop environment (Linux)
+* Improves terminal name detection for Nix packages (#2352, Terminal, Linux)
+* Adds DDC/CI brightness detection support for FreeBSD (Brightness, FreeBSD)
+    * DDC/CI communication can be very slow. Users can set the `ddcciSleep: null` option to skip DDC/CI detection.
+* Reworks the built-in logo printing logic. ASCII logos and modules are now printed line by line, avoiding issues like #2239
+    * Note: Image logos are not affected by this change and still print the entire image first before printing any modules.
+* Adds a new `--logo-padding-bottom` option to control the padding between the bottom of the logo and the first module when `--logo-position top` is used
+    * Previously, `--logo-padding-right` was used for both right and bottom padding.
+* Adds `Samsung Exynos 2600` to CPU detection (CPU, Android)
+* Adds terminal font detection support for the Muxy terminal (TerminalFont, macOS)
+* Improves the performance of BusyBox (ash) version detection and always reports `ash` as the pretty name (Shell, Linux)
+
+Bugfixes:
+* Fixes SwayFX version detection (WM, Linux)
+* Fixes fallback font detection for Ghostty (TerminalFont, macOS)
+* Fixes `--stat` output to correctly align with the right border (Global)
+* Fixes boot manager on macOS 26 (mBoot) is incorrectly reported as `iBoot` (Bootmgr, macOS)
+
+Logos:

+* Adds support for the Enlightenment desktop environment (#2165, WM, Linux)
+* Adds support for playback progress detection (Media)
+    * The module now prints the current playback position and total media duration when supported by the player. If you prefer the previous behavior, you can set `media.percent.type: ["hide-others"]` to hide the new fields.
+* Adds support for `global.playerName` for Windows (Media, Windows)
+    * This allows detecting a specified media player while ignoring others.
+* Multi-battery detection is enabled on Windows by default (Battery, Windows)
+
+Bugfixes:
+* Improves DisplayServer compatibility on Linux by handling newer `kde-output-device-v2` protocol updates (DisplayServer, Linux)

+Logos:
+* Adds EN-OS, LimeOS, Redrose and Uzbek
+
+# 2.62.0
+
+Changes:
+* Sort package managers alphabetically in output and format arguments (Packages)
+    * The positional order of format arguments has changed — this is a breaking change for users relying on numeric placeholders. Named arguments are always preferred; e.g., use `{pacman}` (refer to `fastfetch -h packages-format`) instead of `{1}` to keep your config future-proof.
+

+
+Logos:
+* Updates AerynOS (#2272)
+
+# 2.61.0
+
+Changes:
+* Support for Windows 7 and 8 has been removed.
+    * Windows 8.1 is now the oldest version supported by fastfetch.
+* The GPU module on WSL no longer relies on `DXCore`.
+    * The `directx-headers` dependency is no longer required.
+    * Fastfetch on Linux is now pure C; a C++ compiler is no longer required.
+    * GPU type detection is now slightly less accurate, but detection speed should be slightly faster.
+* The GPU module on Windows now uses `DXCore` for more accurate GPU type detection (requires Windows 10 or later).
+    * This feature is built only when `DXCore` headers are available, which requires installing `mingw-w64-<msystem>-x86_64-directx-headers` on MSYS2.

+
+# 2.59.0
+
+Changes:
+* Fastfetch no longer relies on the unreliable environment variables `$USER` or `%USERPROFILE%` to determine the current username (Title)
+    * People who set `$USER` to customize the Fastfetch title should use `{ "type": "title", "format": "your-custom-user-name" }` to achieve the same result.
+* Fastfetch no longer tries to probe inaccessible remote disk drives on Windows (Disk, Windows)
+    * People who have remote drives may use `{ "type": "disk", "hideFolders": "X:\\" }` to ignore problematic ones.
+    * This change removes some ugly hacks from the codebase and matches the behavior on `*nix`.
+
+Features:
+* Adds Oracle Solaris support (#2176, SunOS)
+* Adds UID / SID detection (Title)
+    * In custom format: `{user-id}`
+* Switches to native GPU detection on GNU/Hurd and removes the `libpciaccess` dependency (GPU, Hurd)
+* Improves memory size detection on macOS (Memory, macOS)
+    * Avoids relying on `hw.memsize_usable` by default, which may not be available on older macOS versions
+* Improves Windows disk detection accuracy and performance (Disk, Windows)
+* Adds more ARM CPU parts and removes duplicated cases (CPU, ARM)
+
+Logos:
+* Adds 6-color support to the NixOS logo (including the small variant) (#2180)
+
+# 2.58.0
+
+An early release to fix compatibility issues with KDE Plasma 6.6.
+
+Breaking changes:
+* The `de.slowVersionDetection` option has been removed. Slow version detection is now always enabled, as required on non-FHS-compliant distros (e.g., NixOS). (#2149, DE, Linux)
+
+Features:
+* Adds the `--structure-disabled <modules...>` command-line flag to temporarily disable module structure printing.
+    * For example: `fastfetch --structure-disabled colors` removes the color blocks from the default output.
+* Supports chassis type detection on Linux ARM devices when reported via the device tree (Chassis, Linux)
+* Supports Bedrock Linux version detection (#2155, OS, Linux)
+* Honors the `DBPath` and `RootDir` settings in `pacman.conf` when detecting Pacman packages (#2154, Packages, Linux)
+
+Bugfixes:
+* Fixes a crash issue on KDE Plasma 6.6 (Display, Linux)
+* Fixes the Command module not working with `--dynamic-interval` (#2152, Command)
+* Fixes Quartz Compositor version detection. It now correctly reports the version of `WindowServer` (`SkyLight`) instead of `WindowManager`. (WM, macOS)
+
+Logos:
+* Adds Kiss2
+
+# 2.57.1
+
+Features:
+* Tiny performance improvements (Windows)
+* Improves the reliability of hostname retrieval (Title, Windows)
+
+Bugfixes:
+* Fixes potential compilation issues on Linux (#2142, Linux)
+* Fixes compilation errors on macOS when building with older SDKs (#2140, macOS)
+* Fixes compilation issues when building with `-DENABLE_SYSTEM_YYJSON=ON` (#2143)
+
+Logos:
+* Updates PrismLinux and adds a small variant
+
+# 2.57.0
+
+Deprecation notice:
+* Support for Windows 7 (and 8.x) is deprecated and will be removed in a future release. Extended support for Windows 7 (and 8.1) ended on January 10, 2023. These versions do not officially support ANSI escape codes (running fastfetch on them requires a third-party terminal such as ConEmu). In addition, Windows 7 lacks some APIs used by fastfetch. Fastfetch currently loads these APIs dynamically at runtime to maintain compatibility, but this adds complexity to the codebase and increases the maintenance burden.
+    * A CMake flag `ENABLE_WIN7_COMPAT:BOOLEAN` has been introduced (defaults to `ON` for now). If set to `OFF`, Windows 7 compatibility code is excluded, and the resulting binaries will support only Windows 10 (version 1607 and later) and Windows 11.
+    * The main prebuilt Windows binaries on the Release page (`fastfetch-windows-amd64.*`) are built with `ENABLE_WIN7_COMPAT=OFF`. These are the binaries used by `scoop` and `winget`. Users who need Windows 7 (or 8.x) support can download the `-win7` variant instead.
+    * ~~The `ENABLE_WIN7_COMPAT` CMake option and the `-win7` variant binaries are planned to be removed in 2.60.0~~.
+
+Features:
+* Supports COSMIC DE version detection (DE, Linux)
+* Supports niri version detection (#2121, WM, Linux)

+* Supports Secure Boot detection (Bootmgr, macOS)
+* Supports DPI scale factor detection on Windows 7 (Display, Windows)
+* Supports xterm 256-color codes in color configuration
+    * In `display.color`: "`@<color-index>`" (e.g., "`@34`" for color index `34`)
+    * In `*.format` strings: "`#@<color-index>`" (e.g., "`#@34`" for color index `34`)
+* Improves uptime accuracy on Windows 10+ (Uptime, Windows)
+* Adds a new module `Logo` to query built-in logo raw data in JSON output (Logo)
+    * Usage: `fastfetch -s logo -l <logo-name> -j # Supported in JSON format only`
+* Supports shell version detection even if the binary has been deleted (#2136, Shell, Linux)
+* Overall code refinements and optimizations

+Thank you for your interest in fastfetch. This document covers building, architecture, how to add a module or a logo, code style, commit conventions, and the pull request workflow.
+
+fastfetch is a system information tool written in C23, supporting Linux, macOS, Windows, the BSDs, Solaris, Haiku and Android. The project places strong emphasis on **startup time** and on keeping **dependencies optional**; many design decisions only make sense under that constraint, and this document returns to it repeatedly.

+## Contributor quick reference
+
+| Task | Start here | Verify with |
+|---|---|---|
+| Build and run fastfetch | `run.sh`, `CMakeLists.txt` | `./run.sh` |
+| Add a module | `src/modules/<name>/`, `src/detection/<name>/`, `src/modules/modules.c`, `CMakeLists.txt` | `cmake -B build && cmake --build build -j` |
+| Add a platform implementation | `src/detection/<name>/<name>_<platform>.c`, the matching platform block in `CMakeLists.txt` | Build on the target platform or CI |
+| Add an ASCII logo | `src/logo/ascii/<letter>/<name>.txt`, matching `<letter>.inc` | `./build/fastfetch --logo <name>` |
+| Change formatting or JSON output | `src/modules/<name>/<name>.c` | `./build/fastfetch -s <name> --format json` |
+| Change shared formatting or containers | `src/common/format.h`, `src/common/color.h`, `src/common/FFstrbuf.h` | Build and run the matching test |
+| Run the test suite | `tests/`, `build/` | `cd build && ctest --output-on-failure` |
+
+For a typical code change, the shortest useful iteration is: configure, build the `fastfetch` target, run the affected module, then run the tests. If you add a directory or a generated input, re-run `cmake -B build` so that CMake refreshes its file globs.
+
+---
+
+## Getting started
+
+### Building
+
+The quickest way is `run.sh` in the repository root: it creates `build/`, configures, compiles and runs the binary.
+
+```sh
+./run.sh                 # build and run
+./run.sh --format json   # arguments are forwarded to fastfetch
+```
+
+Manual build:
+
+```sh
+cmake -B build -DCMAKE_BUILD_TYPE=RelWithDebInfo
+cmake --build build --target fastfetch -j$(nproc)
+./build/fastfetch
+```
+
+The default build type is `RelWithDebInfo`. LTO is enabled whenever `ENABLE_LTO=ON` **and** `CMAKE_BUILD_TYPE != Debug`, so the default configuration enables it and only `Debug` builds omit it. This is significant because LTO here is not merely an optimization: it is what removes the code of disabled modules. See [Pitfalls](#pitfalls).
+
+### Common build options
+
+| Option | Default | Notes |
+|---|---|---|
+| `CMAKE_BUILD_TYPE` | `RelWithDebInfo` | LTO is on for anything but `Debug` |
+| `BUILD_TESTS` | `OFF` | Builds the unit tests in `tests/` |
+| `BUILD_FLASHFETCH` | `ON` | Also builds the stripped-down `flashfetch` |
+| `BINARY_LINK_TYPE` | `dlopen` | `dlopen` / `dynamic` / `static` |
+| `ENABLE_ASAN` | `OFF` | Address Sanitizer |
+| `ENABLE_LTO` | `ON` | Link-time optimization |
+| `MODULE_DISABLE_<NAME>` | `OFF` | Disable a module, e.g. `MODULE_DISABLE_GPU=ON` |
+| `SET_TWEAK` | `ON` | Appends a tweak to the dev version; turned off for releases |
+
+`BINARY_LINK_TYPE=dlopen` (the default) is a deliberate design choice: optional dependencies (Vulkan, Wayland, DBus, ImageMagick, chafa, …) are loaded at runtime, so a missing library never prevents startup. When adding a third-party dependency, use the dlopen helpers in `common/library.h` — do not link it directly.
+
+For a minimal-dependency build, see `.github/workflows/build-no-features-test.yml`:
+
+```sh
+cmake -DBUILD_TESTS=On -DENABLE_VULKAN=OFF -DENABLE_WAYLAND=OFF -DENABLE_X11=OFF \
+      -DENABLE_DBUS=OFF -DENABLE_ZLIB=OFF ... .
+```
+
+### Dependencies
+
+Required: CMake ≥ 3.21 and a C23 compiler (GCC, Clang or MSVC). Everything else is optional.
+
+Optional dependencies are auto-detected: libpci, libdrm, vulkan, wayland, xcb, xrandr, dbus, sqlite3, rpm, imagemagick{6,7}, chafa, zlib, egl, glx, opencl, freetype, pulse, ddcutil, elf, libzfs, and more.

+
+Flow of control:
+
+```
+fastfetch.c  →  options/    (global configuration)
+             →  modules/    (76 modules, formatting and output)
+             →  detection/  (one platform implementation each, raw data)
+             →  common/     (infrastructure)
+```
+
+The number of module directories does not match the number of detection directories, which is expected. The following relationships are structural rather than a fixed inventory:
+
+- **13 modules have no detection directory** — they are either pure layout (`break`, `separator`, `colors`, `title`, `logo`) or reuse another module's detection result (`display`, `monitor`, `kernel`, `shell`, `terminal`, `player`, `custom`, `datetime`).
+- **4 detection directories serve modules with different names** — `displayserver` (→ `display`, `monitor`), `gtk_qt` (→ `theme`, `icons`, `font`, `cursor`), `terminalshell` (→ `terminal`, `shell`) and `libc`.
+
+Therefore, do not assume that `modules/<x>/` always has a matching `detection/<x>/`.
+
+### Layer boundaries
+
+| Layer | Owns | Must not |
+|---|---|---|
+| `options/` | **Global** config (colors, logo, threading, timeouts) | hold per-module options |
+| `modules/` | formatting, printing, JSON serialization | read `/proc`, call Win32 APIs, parse sysfs |
+| `detection/` | cross-platform data retrieval, clean result structs | print anything, read display config |
+| `common/` | general-purpose utilities, no business logic | depend on a specific module |
+
+A simple check: **no file under `detection/` should contain `printf` or read `instance.config`.** Symmetrically, no file under `modules/` should contain `#ifdef __linux__`.
+
+---
+
+## Core architecture: modules vs. detection
+
+This is the most important convention in the codebase. Every feature consists of a fixed set of files; using CPU as the example:
+
+```
+modules/cpu/option.h           module option struct
+modules/cpu/cpu.c              formatting and output
+detection/cpu/cpu.h            platform-independent interface
+detection/cpu/cpu_linux.c     ┐
+detection/cpu/cpu_apple.c     │
+detection/cpu/cpu_windows.c   ├─ platform implementations, one linked per build
+detection/cpu/cpu_bsd.c       │
+detection/cpu/cpu_nosupport.c ┘
+```
+
+The interface is deliberately minimal, typically consisting of only two declarations:
+
+```c
+typedef struct FFCPUResult { ... } FFCPUResult;   // result struct
+const char* ffDetectCPU(const FFCPUOptions* options, FFCPUResult* cpu);
+```
+
+The `const char*` return value is an **error string**; `nullptr` means success. This pattern is used throughout `detection/` — please keep it consistent.
+
+Helper functions are only exposed when they are genuinely shared between platform implementations (as in `cpu.h`: `ffCPUAppleCodeToName`, `ffCPUDetectByCpuid`).
+
+**The benefit of this separation:** adding a platform never touches `modules/`; fixing output formatting never touches `detection/`.
+
+---
+
+## Module registration
+
+### The descriptor
+
+Every module exports one `FFModuleBaseInfo` (defined in `common/option.h:46`) — essentially a hand-written vtable:
+
+```c
+typedef struct FFModuleBaseInfo {
+    const char* name;                    // lookup key, e.g. "cpu"
+    const char* description;             // help text
+    FFModuleDisplayName displayName;     // module name in 20 languages
+
+    void (*initOptions)(void* options);
+    void (*destroyOptions)(void* options);
+    void (*parseJsonObject)(void* options, struct yyjson_val* module);
+    bool (*printModule)(void* options);
+    bool (*generateJsonResult)(void* options, yyjson_mut_doc*, yyjson_mut_val*);
+    void (*generateJsonConfig)(void* options, yyjson_mut_doc*, yyjson_mut_val*);
+
+    FFModuleFormatArgList formatArgs;    // format placeholder table
+    const uint8_t defaultOrder;          // sort weight
+} FFModuleBaseInfo;
+```
+
+The source comment acknowledges that this is undefined behavior, since `void*` is not compatible with `FF*Options*`. It is a pragmatic compromise to obtain polymorphism in C; do not attempt to "fix" it.
+
+### The registry: a first-letter hash bucket
+
+`src/modules/modules.c` defines 26 `static FFModuleBaseInfo*` arrays (`A[]` through `Z[]`), each terminated by `nullptr`, collected into `ffModuleInfos[26]`:
+
+```c
+FFModuleBaseInfo** modules = ffModuleInfos[toupper(name[0]) - 'A'];  // O(1) bucket lookup
+for (; *modules; ++modules) {                                        // linear scan in the bucket
+    if (ffStrEqualsIgnCase(name, (*modules)->name)) { ... }
+}
+```
+
+Because the registry is small, a single arithmetic bucket lookup followed by a few string comparisons is preferable to a general-purpose hash table. When adding a module, place its descriptor in the bucket matching the first letter of `.name`, and keep the existing `nullptr` terminator at the end.
+
+### The calling convention: zero heap allocation
+
+Every dispatch site (`jsonconfig.c:98`, `commandoption.c:189`) follows the same pattern:
+
+```c
+alignas(uint64_t) uint8_t optionBuf[FF_OPTION_MAX_SIZE];  // 256 bytes, on the stack
+baseInfo->initOptions(optionBuf);
+baseInfo->parseJsonObject(optionBuf, jsonVal);             // JSONC path only
+baseInfo->printModule(optionBuf);                          // or generateJsonResult
+baseInfo->destroyOptions(optionBuf);
+```
+
+`FF_OPTION_MAX_SIZE = 1 << 8` (256 bytes). Every module's `option.h` must end with:
+
+```c
+static_assert(sizeof(FFCPUOptions) <= FF_OPTION_MAX_SIZE, "FFCPUOptions size exceeds maximum allowed size");
+```
+
+**In other words, no module option struct may exceed 256 bytes.** This is a hard constraint, enforced at compile time.
+
+The three dispatch entry points:
+
+| Entry point | Location | Used for |
+|---|---|---|
+| `parseModuleJsonObject` | `common/impl/jsonconfig.c:90` | the `modules[]` array in a JSONC config |
+| `parseStructureCommand` | `common/impl/commandoption.c:181` | the colon-separated structure string |
+
+### Build-time module discovery
+
+`CMakeLists.txt:134` globs `src/modules/*/*.c`, keeps only the entries whose file name matches their directory name, and generates a `MODULE_DISABLE_<UPPER>` option for each:
+
+```cmake
+file(GLOB FF_MODULE_SRCS CONFIGURE_DEPENDS RELATIVE "..." ".../src/modules/*/*.c")
+set(FF_MODULE_DIRS "")
+foreach(FF_MODULE_SRC ${FF_MODULE_SRCS})
+    get_filename_component(FF_MODULE_DIR "${FF_MODULE_SRC}" DIRECTORY)
+    get_filename_component(FF_MODULE_NAME "${FF_MODULE_SRC}" NAME_WE)
+    if("${FF_MODULE_DIR}" STREQUAL "${FF_MODULE_NAME}")
+        list(APPEND FF_MODULE_DIRS "${FF_MODULE_DIR}")
+    endif()
+endforeach()
+
+foreach(FF_MODULE_DIR ${FF_MODULE_DIRS})
+    string(TOUPPER "${FF_MODULE_DIR}" FF_MODULE_UPPER)
+    option(MODULE_DISABLE_${FF_MODULE_UPPER} "Disable module ${FF_MODULE_DIR}" OFF)
+endforeach()
+```
+
+Because the glob matches sources rather than directories, a directory counts as a module only when `src/modules/<name>/<name>.c` exists. Empty directories — which git does not track, so they are easy to leave behind — and stray files are ignored instead of breaking the configure step with `Cannot find source file`.
+
+### Module sources are discovered automatically
+
+`FF_MODULE_DIRS` also drives the source list (`CMakeLists.txt:516`):
+
+```cmake
+foreach(FF_MODULE_DIR ${FF_MODULE_DIRS})
+    list(APPEND LIBFASTFETCH_SRC
+        src/modules/${FF_MODULE_DIR}/${FF_MODULE_DIR}.c
+    )
+endforeach()
+```
+
+Consequences:
+
+- `src/modules/<name>/<name>.c` is compiled as soon as the file exists — **there is no source list to edit for the module layer**.
+- The file name must match the directory name. A directory whose `.c` file is named differently, or has none at all, is silently not a module: a typo therefore shows up as a module missing from `fastfetch --list-modules`, not as a build error.
+- The glob uses `CONFIGURE_DEPENDS`, so with the Makefile and Ninja generators the build re-evaluates it and re-runs CMake when a module source is added or removed. With other generators, or to be safe, re-run `cmake -B build` explicitly.
+
+Only the module layer is automated. Sources under `src/detection/` and `src/common/impl/` are **not** globbed and must still be listed by hand — see [step 5](#5-add-the-platform-sources-to-cmakeliststxt).
+
+---
+
+## Walkthrough: adding a module
+
+Adding a `Foo` module, step by step.
+
+### 1. Define the option struct
+
+`src/modules/foo/option.h`:
+
+```c
+#pragma once
+
+#include "common/option.h"
+
+typedef struct FFFooOptions {
+    FFModuleArgs moduleArgs;   // must be the first field
+    bool showBar;
+} FFFooOptions;
+
+static_assert(sizeof(FFFooOptions) <= FF_OPTION_MAX_SIZE, "FFFooOptions size exceeds maximum allowed size");
+```
+
+`FFModuleArgs` must come first. It provides `key`, `format`, `outputColor`, `keyColor`, `keyIcon` and `keyWidth`; because it is the first field, `ffJsonConfigParseModuleArgs()` handles these generically, **so no parsing code is required**.
+
+### 2. Implement detection
+
+`src/detection/foo/foo.h`:
+
+```c
+#pragma once
+#include "fastfetch.h"
+
+typedef struct FFFooResult {
+    FFstrbuf name;
+    uint32_t count;
+} FFFooResult;
+
+const char* ffDetectFoo(const FFFooOptions* options, FFFooResult* result);
+```
+
+`src/detection/foo/foo_linux.c`:
+
+```c
+#include "foo.h"
+
+const char* ffDetectFoo(const FFFooOptions* options, FFFooResult* result) {
+    // read /sys, /proc, sysfs, dbus, ...
+    return nullptr;  // success; return an error string on failure
+}
+```
+
+**Write one file per target platform, plus a `foo_nosupport.c` fallback for the remaining platforms.** The repository currently contains 45 `*_nosupport.c` files serving this purpose.
+
+### 3. Implement the module
+
+`src/modules/foo/foo.c` — implement the six functions, then define the descriptor:
+
+```c
+FFModuleBaseInfo ffFooModuleInfo = {

+    .description = "Print foo information",
+    .displayName = {
+        .en = "Foo", .ar = "Foo", .cs = "Foo", .de = "Foo", .es = "Foo",
+        .fr = "Foo", .gl = "Foo", .he = "Foo", .id = "Foo", .it = "Foo",
+        .ja = "Foo", .ko = "Foo", .pl = "Foo", .pt = "Foo", .ru = "Foo",
+        .tr = "Foo", .uk = "Foo", .vi = "Foo", .zh_CN = "Foo", .zh_TW = "Foo",

+    })),
+    .defaultOrder = 73,
+};
+```
+
+Points to note:
+
+- **`displayName`** is a literal block of all 20 language fields; there is no shortcut macro, so copy the layout from an existing module: **`en`, `ar`, `cs`, `de`, `es`, `fr`, `gl`, `he`, `id`, `it`, `ja`, `ko`, `pl`, `pt`, `ru`, `tr`, `uk`, `vi`, `zh_CN`, `zh_TW`**.
+  **Fill in all 20.** The struct is read by byte offset (see [Pitfalls](#6-localization-uses-byte-offsets-not-enums)) and there is **no fallback** — a missing field means the key prints empty in that language.
+- **`formatArgs`** must be exhaustive. It drives the placeholder list printed by `fastfetch -h foo-format`; **any placeholder omitted here is neither listed nor usable by the user.**
+- The `moduleFormat` section in `doc/json_schema.json` is generated by `fastfetch -h format-json`. Its metadata comes from `FFModuleBaseInfo::formatArgs`. To keep the schema and module descriptors consistent, do not edit the `moduleFormat` section in `doc/json_schema.json` by hand; update the module metadata and regenerate it instead.
+- **`defaultOrder`**: use the current maximum plus 1. Search the existing descriptors for `.defaultOrder =` before choosing a value; do not copy a hard-coded value from this document. Leaving it out, or setting it to `0`, excludes the module from the interactive `--gen-config` picker. Only `logo`, `command` and `custom` rely on this behavior, because they require user arguments or are invoked directly by the display layer.
+
+### 4. Register it
+
+- Add `#include "modules/foo/foo.h"` to `src/modules/modules.h`
+- Insert into the `F[]` array in `src/modules/modules.c`:
+
+```c
+#if !FF_MODULE_DISABLE_FOO
+    &ffFooModuleInfo,
+#endif
+```
+
+`FF_MODULE_DISABLE_FOO` is generated by CMake — you do not define it yourself.
+
+### 5. Add the platform sources to `CMakeLists.txt`
+
+The module layer is discovered by glob (see [Build-time module discovery](#module-sources-are-discovered-automatically)), **but `src/detection/**` and `src/common/impl/**` are not**. `CMakeLists.txt` lists them explicitly, inside one mutually exclusive chain of platform blocks:
+
+| Block | Line | Covers |
+|---|---|---|
+| `if(LINUX)` | `CMakeLists.txt:522` | Linux |
+| `elseif(ANDROID)` | `CMakeLists.txt:608` | Android (Termux) |
+| `elseif(FreeBSD)` | `CMakeLists.txt:691` | FreeBSD, MidnightBSD, DragonFly |
+| `elseif(NetBSD)` | `CMakeLists.txt:788` | NetBSD |
+| `elseif(OpenBSD)` | `CMakeLists.txt:872` | OpenBSD |
+| `elseif(APPLE)` | `CMakeLists.txt:959` | macOS / iOS |
+| `elseif(WIN32)` | `CMakeLists.txt:1046` | Windows |
+| `elseif(SunOS)` | `CMakeLists.txt:1121` | Solaris / illumos |
+| `elseif(Haiku)` | `CMakeLists.txt:1204` | Haiku |
+| `elseif(GNU)` | `CMakeLists.txt:1282` | GNU/Hurd |
+
+Add the platform implementation to every block whose platform it supports, and `foo_nosupport.c` to every remaining block, so that all ten platforms still link:
+
+```cmake
+elseif(FreeBSD)
+    list(APPEND LIBFASTFETCH_SRC
+        ...
+        src/detection/foo/foo_bsd.c
+    )
+```
+
+Points to note:
+
+- Exactly one block is compiled per build, so a file omitted from a block does not exist for that platform, and the link fails with an undefined reference to `ffDetectFoo()` — **on that platform only**. A missing entry therefore builds fine locally and fails in CI; this is why every block must be covered.
+- A platform may reuse another platform's implementation instead of a stub. `src/common/impl/networking_linux.c`, for example, is listed in nine of the ten blocks (all but `WIN32`). Check where the closest sibling module points before adding a new file.
+- `DragonFly` is handled by the inner `if(DragonFly)` sub-block inside the FreeBSD block (`CMakeLists.txt:773`); add the variant there, as `processes`, `top` and `wifi` do.
+- New helpers under `src/common/impl/` follow the same rule: they are not globbed, and each block that needs one must list it.
+- A few files are appended outside the platform chain because they depend on an option or on a specific feature — for example the proprietary GPU backends (`CMakeLists.txt:1379`) and `src/common/impl/wcwidth.c` (`CMakeLists.txt:1408`). Those are written by hand as well.
+
+### 6. Modules that need warm-up
+
+If your module needs a sampling interval (CPU usage) or a network round-trip (public IP, weather), also implement `ffPrepareFoo()` and register it in the switch inside `ffPrepareCommandOption()` in `common/impl/commandoption.c`, under the matching first-letter `case`. Six modules currently do this: CPUUsage, DiskIO, NetIO, PublicIP, Top and Weather.
+
+### 7. Verify
+
+```sh
+cmake -B build && cmake --build build -j
+./build/fastfetch -s foo --format json    # JSON output
+./build/fastfetch -h foo-format           # list formatArgs placeholders
+./build/fastfetch --gen-config            # confirm it appears in the picker
+```
+
+Note the `-format` suffix on the help flag: `fastfetch -h foo` is not supported; only `fastfetch -h foo-format` works.
+
+If you added detection sources, re-check [step 5](#5-add-the-platform-sources-to-cmakeliststxt) before pushing: a platform block you missed compiles fine locally and fails only when that platform is built.

+
+## Walkthrough: adding a logo
+
+A new logo **must** have a corresponding "Logo Request" issue, linked from the PR with `Closes #1234`. Logo PRs without a linked issue are not accepted.
+
+### 1. Add the ASCII file
+
+```
+src/logo/ascii/<first-letter>/<distro>.txt
+```
+
+For example `src/logo/ascii/d/distro.txt`. Directories are already split by first letter (`a/` … `z/`, plus `_/`).
+
+The file is plain ASCII art with `$1` … `$9` as color placeholders:
+
+```
+                 $3 ,-^-___
+$3                /\\\///
+$2refined.$1       /\\\\//
+```
+
+- `$1` … `$9` map to palette slots 1–9; at most 9 are supported (`FASTFETCH_LOGO_MAX_COLORS = 9`)
+- `$$` is a literal `$`
+- Characters without a placeholder inherit the current color. Of the 530 existing logos, 239 use no placeholders at all (monochrome) and 291 do; **new logos should use placeholders**, as monochrome is a legacy style
+- Tabs are expanded to 4 spaces
+- Colors can be overridden with `--logo-color-1` … `--logo-color-9`
+
+### 2. Register it in the `.inc`
+
+CMake turns each `.txt` file into a `FASTFETCH_DATATEXT_LOGO_<UPPERCASE>` macro (`CMakeLists.txt:418`), but **the registry itself is maintained by hand**. Edit `src/logo/ascii/<first-letter>.inc`:
+
+```c
+// src/logo/ascii/d.inc
+
+#ifdef FASTFETCH_DATATEXT_LOGO_DISTRO
+// Distro
+{
+    .names = { "Distro" }, // ID (preferred) or NAME from /etc/os-release, do NOT add both
+    .lines = FASTFETCH_DATATEXT_LOGO_DISTRO,
+    .colors = {
+        FF_COLOR_FG_PRIMARY, // recommended for using as WHITE replacement, light-theme terminal friendly
+        FF_COLOR_FG_BLUE, // preferred
+        FF_COLOR_FG_256 "34",
+        FF_COLOR_FG_RGB "0;255;0", // not recommended because of bad compatibility with raw TTY
+    },
+},
+#endif
+```
+
+- `names` is matched case-insensitively. Do not add names that differ only by case, because they can never be distinguished. Every name is also shown by `--list-logos`, so use user-friendly spelling such as an initial capital where appropriate.
+- For a new logo, use exactly one name unless there is a specific compatibility reason to add more. That name should first be the `ID` from `/etc/os-release`. If the ID cannot distinguish this logo from another logo for the same OS, use the `NAME` value instead. `logoGetBuiltinDetected` in `src/logo/logo.c` documents the detection order: `ID`, then `NAME`, then tokens from `ID_LIKE`, then the platform name fallback. Manual `logo-source` selection uses the name directly.
+- `colors` is positional — entry 0 is `$1`, entry 1 is `$2`, and so on
+- `colors[0]` also becomes the title color and `colors[1]` the key color, unless the user overrides them
+
+If the same OS has multiple logo variants, mark the variant explicitly with `.type`:
+
+```c
+.type = FF_LOGO_LINE_TYPE_SMALL_BIT,
+```
+
+Use `FF_LOGO_LINE_TYPE_ALTER_BIT` for an alternate logo, `FF_LOGO_LINE_TYPE_SMALL_BIT` for a small logo, or combine the flags when both apply. This is also a lookup optimization: a logo marked `FF_LOGO_LINE_TYPE_SMALL_BIT` is considered only for `type = small`, while a logo marked `FF_LOGO_LINE_TYPE_ALTER_BIT` is never selected by automatic detection. Alternate logos are available only when explicitly requested through `-l <source>`.
+
+### 3. Verify
+
+```sh
+./build/fastfetch -l distro
+./build/fastfetch --list-logos | grep -i distro
+```
+
+---
+
+## Platform conventions
+
+The `detection/` layer picks its implementation by **filename suffix**; the choice is made at build time from `CMAKE_SYSTEM_NAME`:
+
+| Suffix | Platform |
+|---|---|
+| `_linux.c` | Linux |
+| `_apple.c` / `_apple.m` | macOS / iOS (`.m` for Objective-C) |
+| `_windows.c` / `_windows.cpp` | Windows (`.cpp` for WinRT / WMI) |
+| `_bsd.c` | FreeBSD |
+| `_nbsd.c` | NetBSD |
+| `_obsd.c` | OpenBSD |
+| `_sunos.c` | Solaris / illumos |
+| `_haiku.c` / `.cpp` | Haiku |
+| `_android.c` | Android (Termux) |
+| `_gnu.c` | GNU/Hurd |
+| `_nosupport.c` | Empty fallback |
+
+Current distribution of platform files in `detection/`:
+
+| Suffix | Files | Suffix | Files |
+|---|---|---|---|
+| `_linux` | 58 | `_obsd` | 16 |
+| `_windows` | 47 | `_haiku` | 13 |
+| `_apple` | 46 | `_android` | 12 |
+| `_nosupport` | 45 | `_gnu` | 3 |
+| `_bsd` | 29 | | |
+| `_sunos` | 19 | | |
+| `_nbsd` | 17 | | |
+
+(These are repository inventory figures, counting `.c`, `.m`, `.cpp`, and `.h`; they may change as platforms and modules are added.)
+
+**Do not accumulate `#ifdef __linux__` blocks in a single file.** When adding platform support, copy the closest existing implementation and change the suffix.
+
+`common/` follows the same convention: `common/impl/` contains `io_unix.c` / `io_windows.c`, `netif_linux.c` / `netif_apple.c` / `netif_bsd.c` and similar files, with `common/apple/`, `common/windows/` and `common/haiku/` holding platform-specific helpers.
+
+When several platform suffixes could apply, use the most specific implementation supported by the build system (for example, `_nbsd.c` instead of the generic `_bsd.c` on NetBSD). Keep the generic file as the fallback for platforms that share its conventions.
+
+---
+
+## Code style
+
+### Formatting
+
+The project uses clang-format with `BasedOnStyle: LLVM` plus these key overrides:
+
+```yaml
+IndentWidth: 4
+UseTab: Never
+ColumnLimit: 0              # never wrap
+InsertBraces: true          # braces even on single-statement ifs
+PointerAlignment: Left      # char* p, not char *p
+SortIncludes: Never         # include order is managed by hand
+AlignAfterOpenBracket: DontAlign
+BinPackParameters: false    # all params on one line, or one per line
+```
+
+Before committing:
+
+```sh
+clang-format -i src/modules/foo/*.c src/modules/foo/*.h
+```
+
+`src/3rdparty/**`, `build/**` and `src/logo/builtin.c` are listed in `.clang-format-ignore` — **do not reformat them.**
+
+`.editorconfig` specifies LF line endings, a 4-space indent, a final newline, and trailing whitespace trimmed (except in Markdown).
+
+### Naming
+
+| Kind | Convention | Example |
+|---|---|---|
+| Functions | `ff` + PascalCase | `ffDetectCPU`, `ffPrintCPU` |
+| Types | `FF` + PascalCase | `FFCPUResult`, `FFModuleBaseInfo` |
+| Variables / fields | camelCase | `coresPhysical`, `keyWidth` |
+| Macros | SCREAMING_SNAKE_CASE | `FF_OPTION_MAX_SIZE` |
+| Module options | `FF<Name>Options` | `FFCPUOptions` |
+| Detection results | `FF<Name>Result` | `FFCPUResult` |
+
+### Spelling
+
+CI runs codespell (`.codespellrc`). Known false positives are listed in `ignore-words-list` (`iterm`, `compiletime`, and various non-English distro words). Add new words there rather than changing the code.
+
+### Compiler warnings
+
+The build enables `-Wall -Wextra -Wconversion` plus several `-Werror`s:
+
+```
+-Werror=uninitialized -Werror=return-type -Werror=vla
+-Werror=incompatible-pointer-types -Werror=implicit-function-declaration -Werror=int-conversion
+```
+
+**`-Wconversion` is strict**: every implicit narrowing conversion needs an explicit cast.
+
+---
+
+## Commit messages
+
+Format:
+
+```
+<Scope>[ (Platform)]: <third-person singular verb> <object>
+```
+
+Scope is the module or subsystem name; Platform is optional. Use the third-person singular present tense, capitalize the first letter, no trailing period.
+
+Real examples from recent history:
+
+```
+Processes (Haiku): honors `options->countKprocs`
+WM (macOS): improves reliability of WM plugin detection
+Memory (Windows): prefers `NQSI`
+Top (Linux): improves performance of `stat` parsing
+Logo (Builtin): adds omarchy
+Global: introduces global macro `FF_PATH_PKG_BASE` to replace `_PATH_LOCALBASE`
+LM (OpenBSD): adds support
+CI: disables fail on alert
+Doc: updates README
+Presets: moves `top` to the bottom of running modules [ci skip]
+```
+
+Common verbs: `adds`, `removes`, `fixes`, `improves`, `updates`, `corrects`, `prefers`, `honors`, `disables`, `enables`, `introduces`, `detects`, `reports`, `skips`, `uses`.
+
+Scopes in use: `Top`, `Processes`, `Memory`, `Logo (Builtin)`, `CI`, `Doc`, `Presets`, `Global`, plus individual module names.
+
+Documentation-only changes use a `[ci skip]` suffix.

+
+## Tests
+
+Tests are standalone executables in `tests/` using a `VERIFY` macro that exits non-zero on failure:
+
+```c
+#define VERIFY(expression) \
+    if (!(expression)) testFailed(&strbuf, #expression, __LINE__)
+```
+
+Current tests: `strbuf.c`, `list.c`, `format.c`, `color.c`, `duration.c`, `strutil.c`.
+
+```sh
+cmake -B build -DBUILD_TESTS=On
+cmake --build build
+cd build && ctest --output-on-failure
+```
+
+Coverage focuses on the core data structures and the formatting engine in `common/`. The `detection/` layer has no automated tests, because it depends on the state of a running system; it is instead covered by the CI matrix — 20 workflows under `.github/workflows/` spanning Linux (including musl, loong64, armv7l, i686), macOS, Windows, FreeBSD, NetBSD, OpenBSD, DragonFly, Solaris, OmniOS and Haiku, plus spellcheck and benchmark jobs.
+
+**If you modify `common/FFstrbuf.h`, `common/format.h` or `common/color.h`, extend the corresponding test.**
+
+---
+
+## Pull requests
+
+1. **Open an issue first** (feature request / bug report / logo request) to confirm that the change is wanted before investing effort. Templates are in `.github/ISSUE_TEMPLATE/`.
+2. Branch off `dev` — **`dev` is the main development branch**, not `master`.
+3. Follow the [commit message convention](#commit-messages).
+4. Update `CHANGELOG.md` for user-visible changes.
+5. Open the PR against `dev` and fill in `.github/pull_request_template.md`:
+   - Summary
+   - Related issue (**required for new logos**; otherwise the PR is not accepted)
+   - Changes
+   - Screenshots (required for visual changes)
+   - Checklist: confirm you tested locally
+
+### Pre-submit checklist
+
+```sh
+clang-format -i <changed files>                  # format

+./build/fastfetch -c presets/all.jsonc --stat false   # smoke-test every module
+```
+
+---
+
+## Pitfalls
+
+The following points are easy to misinterpret when reading this codebase. Most of them follow from the startup-time objective described above.
+
+### 1. Option structs must not exceed 256 bytes
+
+`FF_OPTION_MAX_SIZE = 1 << 8`. Exceeding it is caught at compile time by `static_assert`. Do not attempt to increase the value: it determines the stack cost of every module invocation.
+
+### 2. `FF_MODULE_DISABLE_*` controls registration, not compilation
+
+```c
+// verbatim from the top of modules/modules.c:
+// FF_MODULE_DISABLE_<module> only controls if the module is registered,
+// the module code itself is still compiled.
+// We rely `LTO` to remove the unused code (only enabled in Release mode)
+```
+
+**Disabling modules in a Debug build does not shrink the binary.** LTO is enabled whenever `CMAKE_BUILD_TYPE != Debug`, and the default `RelWithDebInfo` already satisfies that — so measure size with `RelWithDebInfo` or `Release`, never with `Debug`. (The "Release mode" wording in the comment above is imprecise.)
+
+### 3. Only two things are discovered by glob
+
+The module sources (`CMakeLists.txt:134`) and the logo `.txt` files (`CMakeLists.txt:429`). Both use `CONFIGURE_DEPENDS`, so with the Makefile and Ninja generators the build re-checks the glob and re-runs CMake when the result changes; other generators (Visual Studio and Xcode in particular) do not track it as reliably. Re-run `cmake -B build` after adding a module source or a logo file rather than relying on that behavior.
+
+Everything else — `src/detection/**` and `src/common/impl/**`, and any source outside the platform chain — must be listed in `CMakeLists.txt` by hand; see [step 5](#5-add-the-platform-sources-to-cmakeliststxt).
+
+### 4. CLI module options are removed
+
+Per-module command-line flags such as `--cpu-temp` are **no longer supported**. The only job of `ffParseModuleOptions` now is to translate the flag into a JSON key, then `exit(477)` with a pointer to the config file:
+
+```
+Error: Unsupported module option: --cpu-temp
+       Support of module options has been removed. Please add the flag to the JSON config instead.
+       Example (demonstration only): `{ "modules": [ { "type": "cpu", "temp": true } ] }`
+```
+
+**JSONC is the first-class configuration interface; the command line is not.** When adding module options, implement `parseJsonObject` only — do not add a CLI branch.
+
+### 5. `defaultOrder = 0` hides a module from `--gen-config`
+
+`collectModuleInfos` (`genconfig.c:186`) skips any module whose `defaultOrder` is `0`. C zero-initializes the field, so **omitting it is the same as setting it to 0**. Only `logo`, `command` and `custom` rely on this intentionally.
+
+`defaultOrder` affects only the ordering in the interactive `--gen-config` picker; it has no effect on the runtime output order.
+
+### 6. Localization uses byte offsets, not enums
+
+`instance.config.display.keyLanguage` does not hold a language enum — it holds a **byte offset** such as `offsetof(FFModuleDisplayName, zh_CN)`. The macro `FF_MODULE_GET_DISPLAY_NAME` (`common/option.h:123`) does plain pointer arithmetic with it:
+
+```c
+#define FF_MODULE_GET_DISPLAY_NAME(moduleName) \
+    (*(const char**) ((uint8_t*) &ff ## moduleName ## ModuleInfo.displayName + instance.config.display.keyLanguage))
+```
+
+Consequence: **the field order of `FFModuleDisplayName` must never change** — reordering the fields silently corrupts the output for every language.
+
+### 7. The `multithreading` option has limited effect
+
+The global `multithreading` option currently takes effect in exactly one place: `common/impl/networking_linux.c:339`. Modules are still printed sequentially. Modules that need concurrency go through the `ffPrepare*` warm-up hooks instead, which start sampling or fire off requests before the print loop begins.
+
+This may change in the future. The main blocking issue is that there are dependencies between different modules.
+
+### 8. Do not print or read configuration inside `detection/`
+
+The `detection/` layer must stay pure: read system state, fill a struct, return an error string. Any `printf` or any read of `instance.config` there is a design error.
+
+Use `FF_DEBUG` (`src/common/debug.h`) for logging.
+
+### 9. `src/logo/builtin.c` and `3rdparty/` are formatting-exempt
+
+The former is a large generated and hand-maintained data table; the latter is upstream code. Both are excluded via `.clang-format-ignore`; do not reformat either.

 ### Q: Fastfetch shows fewer dpkg packages than neofetch. Is it a bug?
 
-Neofetch incorrectly counts `rc` packages (packages that have been removed but still have configuration files remaining). See bug: https://github.com/dylanaraps/neofetch/issues/2278
+1. Neofetch incorrectly counts `rc` packages for apt (packages that have been removed but still have configuration files remaining). See bug: https://github.com/dylanaraps/neofetch/issues/2278
+2. Neofetch incorrectly counts `gpg-pubkey` as packages for rpm. You may check the results of `dnf list --installed | wc -l` and `rpm -qa | wc -l` to see the difference.
 
 ### Q: I use Debian / Ubuntu / Debian-derived distro. My GPU is detected as `XXXX Device XXXX (VGA compatible)`. Is this a bug?

+# libsixel (encoder subset, vendored)
+
+Encoder-only subset of [libsixel](https://github.com/saitoha/libsixel) `1.8.7-r2`,
+used by `src/logo/image/` to render the `sixel` logo type **on Windows and macOS**.
+
+## Why this is vendored
+
+Neither MSYS2 nor vcpkg packages libsixel, so on Windows there is nothing to
+`dlopen()` or to link against. The encoder is small and has no external
+dependencies, so the necessary files are embedded instead. The intent is to upstream
+a libsixel package to MSYS2 later and switch to it; until then this directory is the
+source of truth.
+
+macOS *does* have a package — Homebrew's `libsixel` is this very version, `1.8.7-r2`
+(`brew info libsixel`) — but it is deliberately not used. It drags in `jpeg-turbo` /
+`libpng` for the decoder side we never call, and linking it would mean a different
+encoder on each platform. Since Windows needs an embedded copy regardless, one shared
+copy is simpler than two.
+
+## Why only Windows and macOS
+
+Windows loses ImageMagick entirely — its image backend moves to WIC, which decodes
+and scales but cannot *encode* sixel — so it needs an encoder of its own.
+
+macOS does not get ImageMagick either: `ENABLE_IMAGEMAGICK6` / `ENABLE_IMAGEMAGICK7`
+are gated on `LINUX OR FreeBSD OR OpenBSD OR NetBSD OR ANDROID OR SunOS OR Haiku OR
+GNU`, with no `APPLE`, and its image backend is ImageIO. So it shares the same
+requirement.
+
+On every other platform ImageMagick stays, and it already produces sixel through
+its own SIXEL coder. Adding libsixel there would mean a second encoder for a
+capability that already works: one more dependency for zero gain. So `ENABLE_SIXEL`
+is gated on `WIN32 OR APPLE`, and these sources are **not compiled at all** on
+Linux / the BSDs.
+
+Consequence: sixel bytes differ between Windows / macOS (libsixel) and the rest
+(ImageMagick). That is deliberate and accepted — see
+`doc/windows-image-backend.md` decision 9.
+
+## Transparency
+
+The subset is used for its keycolor support. `sixel_dither_set_transparent()` marks a
+palette index as the transparent one; `output_rgb_palette_definition()` then leaves that
+entry out of the palette definition, and `sixel_encode_body()` never puts a keycolor
+pixel into the node map, so nothing is drawn there and the terminal background shows
+through. `src/logo/image/sixel.c` drives this for sources that contain fully transparent
+pixels — it maps those pixels onto a dedicated index one past the quantized palette,
+because keying a *content* colour would also drop every opaque pixel that shares it.
+
+Two things have to line up for the background to actually be transparent: the caller has to
+mark a keycolor, so the keyed pixels are never painted (above), **and** the encoder has to ask
+for a transparent background, so the terminal leaves those unpainted pixels alone instead of
+filling them. The second half is the DCS `P2` parameter — see
+[Local modifications](#local-modifications) item 3.
+
+Note what this is and is not: it is a **palette-index** keycolor, not alpha support. A
+partially transparent pixel has to be drawn in its unblended colour, since a sixel has
+no way to blend with whatever the terminal has behind it.
+
+⚠️ Do not vendor a *newer* libsixel in the belief that this version cannot do
+transparency. It can, and it was measured: the official `1.8.7-r2` omits the keycolor
+entry and leaves the keyed pixels unpainted, with the remaining pixels correctly placed.
+When a transparent background is not showing up, check the caller first — historically
+the caller simply never called `sixel_dither_set_transparent()`, and an image logo only
+renders correctly once it does. If the caller *is* setting a keycolor and the background is
+still solid, check `P2` instead: the keyed pixels are being left unpainted correctly, but the
+terminal is filling them.
+
+## What was kept
+
+Starting from `sixel_dither_new` / `sixel_dither_initialize` / `sixel_output_new` /
+`sixel_encode` and following the dependency closure, only these files are reachable:
+
+| File | Provides |
+|---|---|
+| `tosixel.c` | `sixel_encode`, `sixel_putc`, `sixel_node_*`, DCS envelope handling |
+| `dither.c` / `dither.h` | `sixel_dither_new`, `sixel_dither_initialize`, `sixel_dither_unref` |
+| `output.c` / `output.h` | `sixel_output_new`, `sixel_output_unref` |
+| `quant.c` / `quant.h` | Median-cut palette construction |
+| `pixelformat.c` | `sixel_helper_compute_depth`, `sixel_helper_normalize_pixelformat` |
+| `allocator.c` / `allocator.h` | `sixel_allocator_*` |
+| `status.c` / `status.h` | `sixel_helper_set_additional_message` |
+| `malloc_stub.h` | Included by `allocator.c`; compiles to nothing when `HAVE_MALLOC` |
+| `sixel.h` | Public API (upstream `include/sixel.h`) |
+
+## What was removed
+
+Everything else in the upstream tree, in particular:
+
+- **Decoding**: `decoder.c`, `fromsixel.c`, `frompnm.c`, `fromgif.c`, `frame.c`,
+  `loader.c`, `stb_image.h`, `stb_image_write.*`. Image decoding is done by the
+  platform backend (WIC on Windows, ImageIO on macOS, ImageMagick elsewhere), so
+  libsixel only ever sees an RGBA8 buffer here.
+- **The `sixel_encoder_*` / `sixel_decoder_*` high-level API**: `encoder.c`,
+  `writer.c`, `tty.c`, `scale.c`. These pull in file I/O, terminal probing and the
+  loader registry. We call the dither/output/encode trio directly.
+- **`rgblookup.h` / `rgblookup.gperf`**: a gperf-generated color-name table used
+  only by `encoder.c` for `--builtin-palette` parsing.
+- **`converters/`** (`img2sixel`, `sixel2png`), **`python/`**, **`tools/`**,
+  **`tests/`**, **`images/`** (216 test images), and the packaging templates
+  (`package.json.in.in`, `libsixel.pc.in`).
+- **The autotools machinery**: `configure`, `Makefile.in`, `aclocal.m4`, `m4/`,
+  `ltmain.sh`, `config.h.in`, … See item 2 under
+  [Local modifications](#local-modifications).
+- **Six of the nine `LICENSE.*` files**: `LICENSE.images` / `.mesa` / `.pngsuite` /
+  `.sdump` / `.stb` cover only material that was dropped (test images, the OpenGL
+  example, the `sdump` tool, stb). The three that remain are the complete set
+  required by the files above — verified against each file's own header, see
+  [License](#license).
+
+Result: **20 files / 256 KB**, down from 319 files / 11.3 MB. Note that 8.0 MB of
+that 11.3 MB was `images/` fixtures, so the meaningful comparison is code:
+`src/` + `include/` went from 50 files / 1.17 MB to 20 files / 256 KB.
+
+## Local modifications
+
+Three deliberate divergences from upstream. Re-apply all three when re-syncing.
+
+1. **`sixel.h` — `SIXELAPI` is empty.** Upstream defines it as
+   `__declspec(dllexport)` on Windows. This subset is compiled into `libfastfetch`
+   statically rather than into a standalone DLL, so the attribute would (a) add
+   every libsixel symbol to fastfetch's export table and (b) make `sixel.h`'s
+   declarations disagree with the ones in `dither.h` / `output.h` / `quant.h` /
+   `allocator.h`, which do not carry it (clang warns:
+   `-Wdll-attribute-on-redeclaration`).
+
+2. **`config.h` is hand-written.** Upstream generates it with `configure`. Only
+   these vendored files read it, and they reference a small fixed set of macros,
+   so the values are hard-coded. Two things to watch:
+   - `HAVE_TESTS` must stay **undefined**, not `0`: `sixel.h` gates its test-only
+     declarations with `#ifdef HAVE_TESTS`, so `#define HAVE_TESTS 0` would still
+     pull in declarations for functions we do not compile.
+   - `HAVE_MEMORY_H` / `HAVE_STRING_H` must be `1`. fastfetch builds with
+     `-Werror=implicit-function-declaration`, so a missing `<memory.h>` /
+     `<string.h>` include in `pixelformat.c` / `status.c` is a hard error.
+
+3. **`tosixel.c` — the DCS `P2` parameter is initialised to 1.** `sixel_encode_header()`
+   declares `int p[3] = {0, 0, 0}`, and the trailing-zero trimming right below it then drops
+   all three, so the envelope is a bare `ESC P q`. That means `P2 = 0`, which tells the
+   terminal to fill every unset pixel with **colour-table entry 0** — and that entry is
+   defined by the image's own palette, so a keycolor image comes out with a solid rectangle
+   behind it rather than transparency. Setting `p[1] = 1` leaves unset pixels untouched.
+
+   The trimming still drops the trailing aspect-ratio parameter, so the envelope is
+   `ESC P 0;1 q`. `P3` defaults to 0 and the two spellings are equivalent — verified by
+   decoding both with libsixel's own decoder and with ImageMagick's. ImageMagick's SIXEL
+   coder and chafa both write `0;1;0` explicitly.
+
+   This only shows up on a terminal that implements the VT340 background rule. Windows
+   Terminal does (`_backgroundFillRequired = (_conformanceLevel == 1 || !transparent)` in
+   `src/terminal/adapter/SixelParser.cpp`), which is where it was reproduced; WezTerm does
+   not fill, so the identical bytes look correct there. It is also why Linux never showed
+   the problem: that path goes through ImageMagick, which already sends `P2 = 1`.
+
+The vendored sources are also exempted from `-Wconversion` in `CMakeLists.txt`:
+upstream has ~160 implicit int→`unsigned char` narrowing warnings. Everything else
+(`-Wall -Wextra` and fastfetch's `-Werror=` set) applies unchanged, and the subset
+compiles clean.
+
+## Re-syncing with upstream
+
+```sh
+VER=1.8.7-r2
+git clone --depth 1 --branch "$VER" https://github.com/saitoha/libsixel /tmp/libsixel
+
+# 1. copy the closure (paths change from src/foo.c to foo.c, include/sixel.h to sixel.h)
+for f in tosixel.c dither.c dither.h output.c output.h quant.c quant.h \
+         pixelformat.c allocator.c allocator.h status.c status.h malloc_stub.h; do
+    cp "/tmp/libsixel/src/$f" .
+done
+cp /tmp/libsixel/include/sixel.h .
+cp /tmp/libsixel/LICENSE /tmp/libsixel/LICENSE.sixel /tmp/libsixel/LICENSE.pnmcolormap .
+
+# 2. re-apply the three local modifications listed above
+# 3. verify
+```
+
+Verification (must be 0 diagnostics, and the encoder must emit a DCS-wrapped stream).
+Both platforms compile this subset, so run it on both:
+
+```sh
+# Windows: CC=/c/msys64/clang64/bin/cc.exe
+# macOS:   CC=cc   (verified with Apple clang 21: 0 diagnostics)
+CC=cc
+FLAGS="-I. -Wall -Wextra -Wconversion -Wno-conversion -Werror=uninitialized \
+ -Werror=return-type -Werror=vla -Werror=incompatible-pointer-types \
+ -Werror=implicit-function-declaration -Werror=int-conversion -std=gnu23"
+for f in tosixel dither output quant allocator pixelformat status; do
+    $CC $FLAGS -c $f.c -o /dev/null || echo "FAILED: $f"
+done
+```
+
+If upstream adds a call from the closure to a new file, the build fails at link
+time with an undefined `sixel_*` symbol — add that file and repeat.

+// Contract attributes used throughout this header:
+//
+// `gnu::pure` marks a function that reads memory (through its arguments and through globals) but
+// writes nothing observable, so the compiler may cache and reorder calls to it. It is applied to
+// the comparison / search accessors, and deliberately NOT to:
+//   * the `To*` converters -- `strtod` / `strtoull` / `strtoll` write `errno`;
+//   * `ffStrbufEndsWithFn` -- the caller-supplied `fn` may have side effects;
+//   * `ffStrbufWriteTo` / `ffStrbufPutTo` -- they write to a `FILE*`.
+//
+// `gnu::nonnull(N)` is added wherever the function dereferences argument N unconditionally. The
+// two cannot be combined with a null check: clang reports `-Wtautological-pointer-compare` /
+// `-Wpointer-bool-conversion` (both in `-Wall`) when a `nonnull` parameter is compared against
+// null, so a redundant `assert(p != nullptr)` is dropped in favour of the attribute. Asserts that
+// state something `nonnull` cannot express -- pointer aliasing (`value != strbuf`), index ranges
+// (`start <= strbuf->length`), or a non-pointer invariant -- are kept.
+//
+// `nodiscard` is NOT applied to the "was the buffer modified" boolean returns
+// (`ffStrbufSubstr*`, `ffStrbufRemoveSubstr`, `ffStrbufEnsureEndsWithC`, ...). Ignoring that
+// result is a normal, intended use of those functions -- `ffStrbufSubstrBefore` alone has 153 call
+// sites and ~147 of them discard the result -- so `nodiscard` would only produce noise.

+// Android exposes no public C API for the system services that carry the data fastfetch wants: the
+// NDK has no BatteryManager / WifiManager, libbinder_ndk only speaks to AIDL HALs (it refuses to
+// prepare a transaction for a binder that has no NDK class), and `/system/bin/service call` costs a
+// fork/exec worth 15-20 ms. What is left is /dev/binder itself, which is all that `service` uses
+// underneath. This header speaks that protocol directly: open() + mmap() + BINDER_WRITE_READ, no
+// extra shared library, no child process, ~0.13 ms per call once a handle is cached.
+//
+// Three details are easy to get wrong. All three were confirmed against the device's own
+// libbinder.so and with a ptrace trace of `service`, and getting any of them wrong makes the
+// service answer BAD_TYPE (0x80000001) or BR_FAILED_REPLY (0x7211):
+//
+//   * A request parcel must start with three int32 values -- strict mode policy, work source and
+//     'SYST'. Parcel::markForBinder() writes nothing for kernel binder, but the receiving side's
+//     Parcel::enforceInterface() still compares the third word against its own header.
+//   * Parcel::writeString16() writes the length, the UTF-16 code units, a UTF-16 NUL terminator and
+//     then pads to four bytes. Skipping the terminator shifts every following field by four bytes.
+//   * A handle arriving in a reply is owned by that reply buffer. It has to be acquired
+//     (BC_ACQUIRE + BC_INCREFS) before BC_FREE_BUFFER; otherwise only a weak reference survives and
+//     every later transaction on it fails, because the kernel looks up a strong reference.
