0.40.0

• Added zero event that is triggered when there's no match
• New actions
  • Added track action which makes fzf track the current item when the
    search result is updated. If the user manually moves the cursor, or the
    item is not in the updated search result, tracking is automatically
    disabled. Tracking is useful when you want to see the surrounding items
    by deleting the query string.

    # Narrow down the list with a query, point to a command,
    # and hit CTRL-T to see its surrounding commands.
    export FZF_CTRL_R_OPTS="
      --preview 'echo {}' --preview-window up:3:hidden:wrap
      --bind 'ctrl-/:toggle-preview'
      --bind 'ctrl-t:track+clear-query'
      --bind 'ctrl-y:execute-silent(echo -n {2..} | pbcopy)+abort'
      --color header:italic
      --header 'Press CTRL-Y to copy command into clipboard'"

  • Added change-header(...)
  • Added transform-header(...)
  • Added toggle-track action
• Fixed --track behavior when used with --tac
  • However, using --track with --tac is not recommended. The resulting
    behavior can be very confusing.
• Bug fixes and improvements
