 -------------------------------------------------------------------------------
 
 nnn v1.0
 2017-04-13
 
 Modifications
 - Behaviour and navigation
   - Detail view (default: disabled) with:
     - file type (directory, regular, symlink etc.)
     - modification time
     - human-readable file size
     - current item in reverse video
     - number of items in current directory
     - full name of currently selected file in 'bar'
   - Show details of the currently selected file (stat, file)
   - Disk usage analyzer mode (within the same fs, doesn't follow symlinks)
   - Directories first (even with sorting)
   - Sort numeric names in numeric order
   - Case-insensitive alphabetic content listing instead of upper case first
   - Key `-` to jump to last visited directory
   - Roll over at the first and last entries of a directory (with Up/Down keys)
   - Removed navigation restriction with relative paths (and let permissions handle it)
   - Sort entries by file size (largest to smallest)
   - Shortcut to invoke file name copier (set using environment variable `NNN_COPIER`)
 - File association
   - Set `NNN_OPENER` to let a desktop opener handle it all. E.g.:
         export NNN_OPENER=xdg-open
         export NNN_OPENER=gnome-open
         export NNN_OPENER=gvfs-open
   - Selective file associations (ignored if `NNN_OPENER` is set):
     - Associate plain text files (determined using file) with vi
     - Associate common audio and video mimes with mpv
     - Associate PDF files with [zathura](https://pwmt.org/projects/zathura/)
     - Removed `less` as default file opener (there is no universal standalone opener utility)
     - You can customize further (see [how to change file associations](#change-file-associations))
   - `NNN_FALLBACK_OPENER` is the last line of defense:
     - If the executable in static file association is missing
     - If a file type was not handled in static file association
     - This may be the best option to set your desktop opener to
   - To enable the desktop file manager key, set `NNN_DE_FILE_MANAGER`. E.g.:
         export NNN_DE_FILE_MANAGER=thunar
 - Optimization
   - All redundant buffer removal
   - All frequently used local chunks now static
   - Removed some redundant string allocation and manipulation
   - Simplified some roundabout procedures
   - Compiler warnings fixed
   - strip the final binary
