junegunn/fzf 0.39.0 on GitHub

Added one event that is triggered when there's only one match

# Automatically select the only match
seq 10 | fzf --bind one:accept

Added --track option that makes fzf track the current selection when the
result list is updated. This can be useful when browsing logs using fzf with
sorting disabled.
```
git log --oneline --graph --color=always | nl |
    fzf --ansi --track --no-sort --layout=reverse-list
```

If you use --listen option without a port number fzf will automatically
allocate an available port and export it as $FZF_PORT environment
variable.

# Automatic port assignment
fzf --listen --bind 'start:execute-silent:echo $FZF_PORT > /tmp/fzf-port'

# Say hello
curl "localhost:$(cat /tmp/fzf-port)" -d 'preview:echo Hello, fzf is listening on $FZF_PORT.'

A carriage return and a line feed character will be rendered as dim ␍ and
␊ respectively.
```
printf "foo\rbar\nbaz" | fzf --read0 --preview 'echo {}'
```
fzf will stop rendering a non-displayable character as a space. This will
likely cause less glitches in the preview window.
```
fzf --preview 'head -1000 /dev/random'
```
