--info=hidden and --info=inline-right will no longer hide the horizontal separator by default. This gives you more flexibility in customizing the layout.

fzf --border --info=inline-right
fzf --border --info=inline-right --separator ═
fzf --border --info=inline-right --no-separator
fzf --border --info=hidden
fzf --border --info=hidden --separator ━
fzf --border --info=hidden --no-separator

Added two environment variables exported to the child processes

FZF_PREVIEW_LABEL
FZF_BORDER_LABEL

# Use the current value of $FZF_PREVIEW_LABEL to determine which actions to perform
git ls-files |
  fzf --header 'Press CTRL-P to change preview mode' \
      --bind='ctrl-p:transform:[[ $FZF_PREVIEW_LABEL =~ cat ]] \
      && echo "change-preview(git log --color=always \{})+change-preview-label([[ log ]])" \
      || echo "change-preview(bat --color=always \{})+change-preview-label([[ cat ]])"'

Renamed track action to track-current to highlight the difference between the global tracking state set by --track and a one-off tracking action
- track is still available as an alias
Added untrack-current and toggle-track-current actions
- *-current actions are no-op when the global tracking state is set
