+# 1.7.1
+
+This release brings a lot of bug fixes and improvements for MacOS. Big thanks to @CarterLi for the help on this!
+
+Features:
+* The color of the title and the keys can now be configured individually, using `--color-keys` and `--color-title` respectively. Some distros have different defaults now, similar to neofetch
+* Swap module, similar to the Memory module, but for swap. Add `Swap` to your structure to enable it (#225)
+
+Logos:
+* Slackware (#227)
+
+Bugfixes:
+* Used disk space is now calculated much more accurately
+* On Linux, GPU names are no longer truncated, if they are longer than 32 characters (#224)
+* On Linux, NVIDIA GPUs once again have a proper name
+
+* On M1 platforms, showing the GPU name no longer crashes the program (#222)
+* Brew package count does now work on M1 platforms too
+* The Vulkan module now does work on MacOS too
+* The OpenGL and OpenCL modules now work on MacOS too (@CarterLi, #226)
+* The LocalIp module now works on MacOS too (@CarterLi, #232)
+* Detecting custom WMs on MacOS does now work
+
+Other:
+* GitHub actions now builds a dmg file for MacOS, as you can see in the release page
+
+# 1.7.0
+
+This release brings support for MacOS!  
+The basics things are working, but it is far from feature parity with Linux.
+I developed this in a VM, so bugs on real hardware are likely.
+If you have a Mac and no idea what to do with your free time, i am very happy to accept pull requests / work on issues.
+
+A lot of things were changed under the hood to make this possible, which should bring better performance and stability on all platforms. 
+
+Besides that, the following things have changed:
+
+Features:
+* The binary prefix used can now be configured, and is used consistently across all modules. Set `--binary-prefix` to `iec` (default), `si` or `jedec`.
+* AMD GPUs now have a much better name, if the file `/usr/share/libdrm/amdgpu.ids` exists. For example my dedicated GPU, which was displayed as `AMD/ATI Radeon RX 5600 OEM/5600 XT / 5700/5700 XT`, is now `AMD Radeon RX 5600M`.
+
+Logos:
+* MacOS
+* CachyOS small (@sirlucjan, #220)
+* MSYS2 (#219)
+
+Bugfixes:
+* the `--file` option, which can be used to display the contents of a file as the logo, is now working again.
+
+# 1.6.5
+
+Fixes parsing quoted values in config files
+
+# 1.6.4
+
+Releasing this, so fedora can package fastfetch. Thanks to @jonathanspw for doing that!
+
+Features:
+* --set-keyless option (#215)
+* Replace `\n`, `\t`, `\e` and `\\` in user provided strings, just like c would do it (#215)
+* APK (Alpine Package Keeper) support (@mxkrsv, #216)
+
+Logos:
+* Alma Linux (@jonathanspw, #214)
+
+Bugfixes:
+* replace deprecated gethostbyname call with getaddrinfo (#217)
+
+# 1.6.3
+
+Fixes installing presets in their own directory (@ceamac, #212)
+
+# 1.6.2
+
+Releasing this, so void linux can package fastfetch.
+
+Logos:
+* Rosa linux (#206)
+* KISS linux (@draumaz, #207)
+* LangitKetujuh (@hervyqa, #208)
+
+Bugfixes:
+* Using musl as libc does work now (#210)
+* XBPS packages are once again printed (#209)
+* configured target dirs are applied to install directories too
+* empty XDG_* env vars don't cause a crash anymore
+
+# 1.6.1
+
+Fixes build on android (#205)
+
+# 1.6.0
+
+Features:
+* Detect QT on more DEs than just KDE Plasma. The [Plasma] category was therefore renamed to [QT]
+* Alacritty font detection
+* Load `/etc/fastfetch/config.conf` before user config
+* Disk: print one decimal point if size < 100GB
+* `--title-fqdn` option, to print fully qualified domain name instead of host name in title
+ 
+Logos:
+* updated old NixOS logo
+
+Bugfixes:
+* Correctly detect GTK on DEs that store their settings in dconf
+* Correctly detect NixOS packages
+* Mutter WM detected once again
+* Show full NixOS version in OS output
+* Don't segfault if an invalid structure is given
+* WSL doesn't output GPU anymore, as the name is always meaningless

 ## Customization
 
 With customization and speed being two competing goals, this project actually builds two executables.  
 The main one being `fastfetch`, which can be very greatly configured via flags. These flags can be made persistent in `~/.config/fastfetch/config.conf`. To view the available options run `fastfetch --help`.  
-The second executable being buildt is called `flashfetch`, which is configured at compile time to eliminate any possible overhead. Configuration of it can be very easily done in [`src/flashfetch.c`](src/flashfetch.c).  
+The second executable being built is called `flashfetch`, which is configured at compile time to eliminate any possible overhead. Configuration of it can be very easily done in [`src/flashfetch.c`](src/flashfetch.c).  
 At the moment the performance difference is measurable, but too small to be human recognizable. But the leap will get bigger with more and more options coming, and on slow machines this might actually make a difference.  
-  
-There are some presets defined for fastfech in [`presets`](presets), you can can load them with `--load-config`. They may also serve as a good example for format arguments.

+There are some premade config files in [`presets`](presets), including the ones used for the screenshots above. You can load them using `--load-config <filename>`. They may also serve as a good example for format arguments.
 
 ## Dependencies
 
 Fastfetch dynamically loads needed libraries if they are available. Therefore its only hard dependencies are `libc` (any implementation of the c standard library), `libdl` and `libpthread`. They are all shipped with [`glibc`](https://www.gnu.org/software/libc/), which is already installed on most linux distributions, so you probably don't have to worry about it.  
 
 The following libraries are used if present at runtime:
-*  [`libpci`](https://github.com/pciutils/pciutils): GPU output.
-*  [`libvulkan`](https://www.vulkan.org/): Fallback for GPU output.
-*  [`libxcb-randr`](https://xcb.freedesktop.org/),
-   [`libXrandr`](https://gitlab.freedesktop.org/xorg/lib/libxrandr),
-   [`libxcb`](https://xcb.freedesktop.org/),
-   [`libX11`](https://gitlab.freedesktop.org/xorg/lib/libx11): At least one of them sould be present in X11 sessions for better resolution detection and faster WM detection. The `*randr` ones provide multi monitor support. The `libxcb*` ones usually have better performance.
-*  [`libwayland-client`](https://wayland.freedesktop.org/): Better resolution performance and output in wayland sessions. Supports different refresh rates per monitor.
-*  [`libGIO`](https://developer.gnome.org/gio/unstable/): Needed for values that are only stored GSettings.
-*  [`libDConf`](https://developer.gnome.org/dconf/unstable/): Needed for values that are only stored in DConf + Fallback for GSettings.
-*  [`libDBus`](https://www.freedesktop.org/wiki/Software/dbus): Needed for detecting current media player and song.
-*  [`libXFConf`](https://gitlab.xfce.org/xfce/xfconf): Needed for XFWM theme and XFCE Terminal font.
-*  [`librpm`](http://rpm.org/): Needed for rpm package count.
+* [`libpci`](https://github.com/pciutils/pciutils): GPU output.
+* [`libvulkan`](https://www.vulkan.org/): Vulkan module & fallback for GPU output.
+* [`libxcb-randr`](https://xcb.freedesktop.org/),
+    [`libXrandr`](https://gitlab.freedesktop.org/xorg/lib/libxrandr),
+    [`libxcb`](https://xcb.freedesktop.org/),

+* [`libDConf`](https://developer.gnome.org/dconf/unstable/): Needed for values that are only stored in DConf + Fallback for GSettings.
+* [`libmagickcore` (ImageMagick)](https://www.imagemagick.org/): Images in terminal using sixel or kitty graphics protocol.
+* [`libchafa`](https://github.com/hpjansson/chafa): Image output as ascii art.
+* [`libZ`](https://www.zlib.net/): Faster image output when using kitty graphics protocol.
+* [`libDBus`](https://www.freedesktop.org/wiki/Software/dbus): Needed for detecting current media player and song.
+* [`libEGL`](https://www.khronos.org/registry/EGL/),
+    [`libGLX`](https://dri.freedesktop.org/wiki/GLX/),
+    [`libOSMesa`](https://docs.mesa3d.org/osmesa.html): At least one of them is needed by the OpenGL module for gl context creation.
+* [`libOpenCL`](https://www.khronos.org/opencl/): OpenCL module
+* [`libXFConf`](https://gitlab.xfce.org/xfce/xfconf): Needed for XFWM theme and XFCE Terminal font.
+* [`libsqlite3`](https://www.sqlite.org/index.html): Needed for rpm package count.
+* [`librpm`](http://rpm.org/): Slower fallback for rpm package count. Needed on openSUSE.

 If pkg-config fails to find the headers for a library listed in [dependencies](#dependencies), fastfetch will simply build without support for that specific feature. This means, it won't look for it at runtime and just act like it isn't available.
 
 ## Packaging
 
-* [AUR](https://aur.archlinux.org/packages/fastfetch-git/): Packaged by me. Will install the fastfetch binary, bash completion and the presets. Git version
-* [Manjaro Repositories](https://gitlab.manjaro.org/packages/community/fastfetch): Packaged by a manjaro maintainer. Usually a bit outdated.
-* [Gentoo (Guru)](https://github.com/gentoo/guru/tree/master/app-misc/fastfetch): Packed by some other guy. May be out of date some times.
-* DEB / RPM: Run `cmake -B build && cmake --build build --target package` to build the packages in build.
-* Manually:
-    * Build: Follow the [build instructions](#building).
-    * Install: `sudo cmake --install build --prefix /usr/local`

@@ -19,24 +19,18 @@ If a "{?}" is found without an opener, it is printed as is.
 To only print something if a variable is not set, do the same as with if, just replace every '?' with a '!'.
 For example to print a fallback for a second value if it is not set, use "{?2}{2}{?}{/2}Second value fallback{/}"
 
-There is a special variable set if an error occured during detection. You can access it with "{e}", "{error}" o

 To print something with color, start a placeholder with a '#' and then the linux terminal color encoding.
 "\\033[" at the start, and an 'm' at the end is automatically added, so don't do that.
 A "{#}" is equivalent to a "{#0}" and resets everything to normal.
 For example to print something pink and underline, use "{#4;35}...{#}".

 Information about what the numbers mean can be found here: https://en.wikipedia.org/wiki/ANSI_escape_code#SGR_(Sele
 Which escape codes are supported and how they look is defined by your terminal.
 
 If a format string evaluates to an empty value, the whole line in the output will be discarded.
 You can therefore use --host-format " " to disable host output.
 Note that --host-format "" would evaluate as not set, and therefore use the built-in host format
-This can be used to print nothing if an error occured: prefix the format string with "{?e}{-}{?}...".
 
 Format string is also the way to go to set a fixed value - just use one without placeholders.
 For example when running in headless mode, you could use "--resolution-format "Preferred".
