0.31.0

• Added support for an alternative preview window layout that is activated
  when the size of the preview window is smaller than a certain threshold.

  # If the width of the preview window is smaller than 50 columns,
  # it will be displayed above the search window.
  fzf --preview 'cat {}' --preview-window 'right,50%,border-left,<50(up,30%,border-bottom)'
  
  # Or you can just hide it like so
  fzf --preview 'cat {}' --preview-window '<50(hidden)'

• fzf now uses SGR mouse mode to properly support mouse on larger terminals
• You can now use characters that do not satisfy unicode.IsGraphic constraint
  for --marker, --pointer, and --ellipsis. Allows Nerd Fonts and stuff.
  Use at your own risk.
• Bug fixes and improvements
• Shell extension
  • kill completion now requires trigger sequence (**) for consistency
