+- 'Tools > Execute mpv command' was replaced with [mpv-repl](https://github.com/rossy/mpv-repl)
+- many [wiki pages](https://github.com/stax76/mpv.net/wiki) were improved
+- the logo/icon had a very small cosmetic change
+- the help in the context menu was improved,
+  for quick access consider the command palette (F1 key)
+- config options specific to mpv.net are now available from the command line
+- the input editor no longer has known limitations, 'alt gr' and ctrl+alt are working now
+- the help in the input editor was simplified and the filter logic was improved
+- fixed issue in file associations causing mpv.net not to appear in OS default apps
+- 'Tools > Manage File Associations' was replaced by 'Tools > OS Setup',
+  it has now a feature to add and remove mpv.net to and from the Path
+  environment variable and the OS default apps settings can be opened (Win 10 only)
+- startup folder and config folder beeing identical was causing a critical issue
+  as mpv.net was loading extensions twice and scripts four times, now identical
+  folders are no longer permitted
+- error messages are shown when unknown scripts and extensions are found in the startup folder
+  because user scripts and extensions are supposed to be located in the config folder instead
+- changing from maximized to fullscreen did not work
+- the search field in the config editor was not always remembered
+- new setting remember-volume added, saves volume and mute on exit
+  and restores it on start.
+- it's now enforced that mpv properties on the command line and in
+  the mpv.conf config file are lowercase, if not a error is shown
+- gpu-api vulkan was not working if media files were opened via
+  command line (that included Explorer)
+- new setting minimum-aspect-ratio added, minimum aspect ratio for the window,
+  this was previously hard coded to 1.3
+- new setting auto-load-folder added, for single files automatically load
+  the entire directory into the playlist, previously this was forced,
+  now it can be disabled
+- new setting themed-menu added, follow theme color in context menu,
+  default: no. UI related settings have now a separate UI tab in the config editor
+
