+- New tutorial: [Extending mpv and mpv.net via Lua scripting](https://github.com/stax76/mpv.net/wiki/Extending-mpv-and-mpv.net-via-Lua-scripting)
+- New options `autofit-image` and `autofit-audio`, like autofit, but used for image and audio files.
+- New [auto-mode](https://github.com/stax76/mpv-scripts) script to use mpv and mpv.net as image viewer and audio player.
+- New [smart-volume](https://github.com/stax76/mpv-scripts) script. Records the volume per file in order to restore it
+  in future sessions. What is recorded and restored is the volume offset relative to the session average volume.
+- New support of the mpv option `snap-window`.
+- New feature to show chapters in the command palette, see binding and menu definition below.
+- New option minimum-aspect-ratio-audio, same as minimum-aspect-ratio but used for audio files.
+- Fix long commands causing key bindings not visible in the command palette.
+- Fix script compatibility with mordenx and mpv-osc-tethys.
+- Fix borderless window not resizable with mouse.
+- Fix start-size=session not working.
+- Fix chapters that are script created after the media file is loaded.
+- Width of command palette slightly increased.
+- The default key bindings for 0 and 9 change the volume, like mpv.
+- When a menu item is defined multiple times with different key bindings,
+  only one menu item is created, it shows all bindings.
