 # 2.0.1
 
+First stable release of Fastfetch V2
+
 Changes:
 * Unescape strings only when parsing `.conf` files
     * Previously: `$ NO_CONFIG=1 fastfetch --os-key \\\\ -s os -l none` prints `\: *`. Note the backslashs are unescaped twice (once by shell and once by fastfetch).
     * Now: `$ NO_CONFIG=1 fastfetch --os-key \\\\ -s os -l none` prints `\\: *`
 * Remove option shortcut `-c` (alias of `--color`), which is more commonly used as alias of `--config`
 * Rename `--recache` to `--logo-recache` (which is used for regenerate image logo cache). Remove option shortcut `-r` (alias of `--recache`).
+* Detecting brightness of external displays with DDC/CI is no longer guarded behind `--allow-slow-operations` (Brightness)
 
 Features:
 * Add `--key-width` for aligning the left edge of values, supported both for global `--key-width` and specific module `--module-key-width`
 * Add `--bar-char-elapsed`, `--bar-char-total`, `--bar-width` and `--bar-border` options
+* Add CMake option `ENABLE_SYSTEM_YYJSON`, which allow building fastfetch with system-provided yyjson (for package managers)
 
 Bugfixes:
 * Fix label detection. Use `--disk-key 'Disk ({2})'` to display it (Disk, Linux)
 * Fix some module options were not inited
+* Fix terminal version and font detection on NixOS (Terminal, Linux)
