     * main: chafa dbus glib imagemagick libelf libxcb libxrandr pulseaudio zlib
     * x11: dconf (Optional)
 * Dependency on `libxfconf` is removed. XFCE related detection now uses `libdbus` instead (Linux)
+* The default format of `Display` module is updated to `{width}x{height} @ {scale-factor}x in {inch}", {refresh-rate} Hz`
+    * Replaced scaled resolution with scale factor for shorter texts and avoiding potential confusion.
 
 Bugfixes:
 * Fixes linking on 32-bit Android (#1939)

 * Enables X11-related info (i.e., WM/DE) detection on Android (Global, Android)
     * This requires many dependencies. See above.
 * Adds scale factors detection for X11 (Display, Linux)
-    * X11 doesn't natively report scale factor as Wayland does. Instead, Fastfetch tries to detect `Xft.dpi` (DPI used by X FreeType to scale fonts), which is usually set by the WM when DPI scaling is enabled.

     * It's not always accurate. For example, XFCE4 has a separate config for text scaling, which is unaffected by the global DPI scaling setting.
-* Adds `display.fraction.trailingZeros: [show|hide]` option for fraction formatting
-* Informs users that module-specific CLI options are no longer supported and provide guidance on transitioning to JSON config
+* Adds `display.fraction.trailingZeros: [always|never]` option for fraction formatting
+    * The default value of `display.fraction.ndigits` is changed from `-1` (unlimited) to `2` for usability.
+    * Used for displaying scale factor in Display module mentioned above, alongside other places for printing raw fraction numbers.
+* Informs users that module-specific CLI options are no longer supported and provide guidance for transitioning to JSON config
 * Adds CPU name detection support for IA64 (CPU, Linux)
 * Support Btrfs allocation profile detection (#1941, Btrfs, Linux)
