 CHANGELOG
 =========
 
-0.37.0
-------
-- Added a way to customize the separator of inline info
-  ```sh
-  fzf --info 'inline: ╱ ' --prompt '╱ ' --color prompt:bright-yellow
-  ```
-- New event
-    - `focus` - Triggered when the focus changes due to a vertical cursor
-      movement or a search result update
-      ```sh
-      fzf --bind 'focus:transform-preview-label:echo [ {} ]' --preview 'cat {}'
-
-      # Any action bound to the event runs synchronously and thus can make the interface sluggish
-      # e.g. lolcat isn't one of the fastest programs, and every cursor movement in
-      #      fzf will be noticeably affected by its execution time
-      fzf --bind 'focus:transform-preview-label:echo [ {} ] | lolcat -f' --preview 'cat {}'
-
-      # Beware not to introduce an infinite loop
-      seq 10 | fzf --bind 'focus:up' --cycle
-      ```
-- New actions
-    - `change-border-label`
-    - `change-preview-label`
-    - `transform-border-label`
-    - `transform-preview-label`
-- Bug fixes and improvements
-
-0.36.0
-------
-- Added `--listen=HTTP_PORT` option to start HTTP server. It allows external
-  processes to send actions to perform via POST method.
-  ```sh
-  # Start HTTP server on port 6266
-  fzf --listen 6266
-
-  # Send actions to the server
-  curl -XPOST localhost:6266 -d 'reload(seq 100)+change-prompt(hundred> )'
-  ```
-- Added draggable scrollbar to the main search window and the preview window
-  ```sh
-  # Hide scrollbar
-  fzf --no-scrollbar
-
-  # Customize scrollbar
-  fzf --scrollbar ┆ --color scrollbar:blue
-  ```
-- New event
-    - Added `load` event that is triggered when the input stream is complete
-      and the initial processing of the list is complete.
-      ```sh
-      # Change the prompt to "loaded" when the input stream is complete
-      (seq 10; sleep 1; seq 11 20) | fzf --prompt 'Loading> ' --bind 'load:change-prompt:Loaded> '
-
-      # You can use it instead of 'start' event without `--sync` if asynchronous
-      # trigger is not an issue.
-      (seq 10; sleep 1; seq 11 20) | fzf --bind 'load:last'
-      ```
-- New actions
-    - Added `pos(...)` action to move the cursor to the numeric position
-        - `first` and `last` are equivalent to `pos(1)` and `pos(-1)` respectively
-      ```sh
-      # Put the cursor on the 10th item
-      seq 100 | fzf --sync --bind 'start:pos(10)'
-
-      # Put the cursor on the 10th to last item
-      seq 100 | fzf --sync --bind 'start:pos(-10)'
-      ```
-    - Added `reload-sync(...)` action which replaces the current list only after
-      the reload process is complete. This is useful when the command takes
-      a while to produce the initial output and you don't want fzf to run against
-      an empty list while the command is running.
-      ```sh
-      # You can still filter and select entries from the initial list for 3 seconds
-      seq 100 | fzf --bind 'load:reload-sync(sleep 3; seq 1000)+unbind(load)'
-      ```
-    - Added `next-selected` and `prev-selected` actions to move between selected
-      items
-      ```sh
-      # `next-selected` will move the pointer to the next selected item below the current line
-      # `prev-selected` will move the pointer to the previous selected item above the current line
-      seq 10 | fzf --multi --bind ctrl-n:next-selected,ctrl-p:prev-selected
-
-      # Both actions respect --layout option
-      seq 10 | fzf --multi --bind ctrl-n:next-selected,ctrl-p:prev-selected --layout reverse
-      ```
-    - Added `change-query(...)` action that simply changes the query string to the
-      given static string. This can be useful when used with `--listen`.
-      ```sh
-      curl localhost:6266 -d "change-query:$(date)"
-      ```
-    - Added `transform-prompt(...)` action for transforming the prompt string
-      using an external command
-      ```sh
-      # Press space to change the prompt string using an external command
-      # (only the first line of the output is taken)
-      fzf --bind 'space:reload(ls),load:transform-prompt(printf "%s> " "$(date)")'
-      ```
-    - Added `transform-query(...)` action for transforming the query string using
-      an external command
-      ```sh
-      # Press space to convert the query to uppercase letters
-      fzf --bind 'space:transform-query(tr "[:lower:]" "[:upper:]" <<< {q})'
-
-      # Bind it to 'change' event for automatic conversion
-      fzf --bind 'change:transform-query(tr "[:lower:]" "[:upper:]" <<< {q})'
-
-      # Can only type numbers
-      fzf --bind 'change:transform-query(sed "s/[^0-9]//g" <<< {q})'
-      ```
-    - `put` action can optionally take an argument string
-      ```sh
-      # a will put 'alpha' on the prompt, ctrl-b will put 'bravo'
-      fzf --bind 'a:put+put(lpha),ctrl-b:put(bravo)'
-      ```
-- Added color name `preview-label` for `--preview-label` (defaults to `label`
-  for `--border-label`)
-- Better support for (Windows) terminals where each box-drawing character
-  takes 2 columns. Set `RUNEWIDTH_EASTASIAN` environment variable to `1`.
-    - On Vim, the variable will be automatically set if `&ambiwidth` is `double`
-- Behavior changes
-    - fzf will always execute the preview command if the command template
-      contains `{q}` even when it's empty. If you prefer the old behavior,
-      you'll have to check if `{q}` is empty in your command.
-      ```sh
-      # This will show // even when the query is empty
-      : | fzf --preview 'echo /{q}/'
-
-      # But if you don't want it,
-      : | fzf --preview '[ -n {q} ] || exit; echo /{q}/'
-      ```
-    - `double-click` will behave the same as `enter` unless otherwise specified,
-      so you don't have to repeat the same action twice in `--bind` in most cases.
-      ```sh
-      # No need to bind 'double-click' to the same action
-      fzf --bind 'enter:execute:less {}' # --bind 'double-click:execute:less {}'
-      ```
-    - If the color for `separator` is not specified, it will default to the
-      color for `border`. Same holds true for `scrollbar`. This is to reduce
-      the number of configuration items required to achieve a consistent color
-      scheme.
-    - If `follow` flag is specified in `--preview-window` option, fzf will
-      automatically scroll to the bottom of the streaming preview output. But
-      when the user manually scrolls the window, the following stops. With
-      this version, fzf will resume following if the user scrolls the window
-      to the bottom.
-    - Default border style on Windows is changed to `sharp` because some
-      Windows terminals are not capable of displaying `rounded` border
-      characters correctly.
-- Minor bug fixes and improvements
-
-0.35.1
-------
-- Fixed a bug where fzf with `--tiebreak=chunk` crashes on inverse match query
-- Fixed a bug where clicking above fzf would paste escape sequences
-
-0.35.0
-------
-- Added `start` event that is triggered only once when fzf finder starts.
-  Since fzf consumes the input stream asynchronously, the input list is not
-  available unless you use `--sync`.
-  ```sh
-  seq 100 | fzf --multi --sync --bind 'start:last+select-all+preview(echo welcome)'
-  ```
-- Added `--border-label` and `--border-label-pos` for putting label on the border
-  ```sh
-  # ANSI color codes are supported
-  # (with https://github.com/busyloop/lolcat)
-  label=$(curl -s http://metaphorpsum.com/sentences/1 | lolcat -f)
-
-  # Border label at the center
-  fzf --height=10 --border --border-label="╢ $label ╟" --color=label:italic:black
-
-  # Left-aligned (positive integer)
-  fzf --height=10 --border --border-label="╢ $label ╟" --border-label-pos=3 --color=label:italic:black
-
-  # Right-aligned (negative integer) on the bottom line (:bottom)
-  fzf --height=10 --border --border-label="╢ $label ╟" --border-label-pos=-3:bottom --color=label:italic:black
-  ```
-- Also added `--preview-label` and `--preview-label-pos` for the border of the
-  preview window
-  ```sh
-  fzf --preview 'cat {}' --border --preview-label=' Preview ' --preview-label-pos=2
-  ```
-- Info panel (match counter) will be followed by a horizontal separator by
-  default
-    - Use `--no-separator` or `--separator=''` to hide the separator
-    - You can specify an arbitrary string that is repeated to form the
-      horizontal separator. e.g. `--separator=╸`
-    - The color of the separator can be customized via `--color=separator:...`
-    - ANSI color codes are also supported
-  ```sh
-  fzf --separator=╸ --color=separator:green
-  fzf --separator=$(lolcat -f -F 1.4 <<< ▁▁▂▃▄▅▆▆▅▄▃▂▁▁) --info=inline
-  ```
-- Added `--border=bold` and `--border=double` along with
-  `--preview-window=border-bold` and `--preview-window=border-double`
-
-0.34.0
-------
-- Added support for adaptive `--height`. If the `--height` value is prefixed
-  with `~`, fzf will automatically determine the height in the range according
-  to the input size.
-  ```sh
-  seq 1 | fzf --height ~70% --border --padding 1 --margin 1
-  seq 10 | fzf --height ~70% --border --padding 1 --margin 1
-  seq 100 | fzf --height ~70% --border --padding 1 --margin 1
-  ```
-    - There are a few limitations
-        - Not compatible with percent top/bottom margin/padding
-          ```sh
-          # This is not allowed (top/bottom margin in percent value)
-          fzf --height ~50% --border --margin 5%,10%
-
-          # This is allowed (top/bottom margin in fixed value)
-          fzf --height ~50% --border --margin 2,10%
-          ```
-        - fzf will not start until it can determine the right height for the input
-          ```sh
-          # fzf will open immediately
-          (sleep 2; seq 10) | fzf --height 50%
-
-          # fzf will open after 2 seconds
-          (sleep 2; seq 10) | fzf --height ~50%
-          (sleep 2; seq 1000) | fzf --height ~50%
-          ```
-- Fixed tcell renderer used to render full-screen fzf on Windows
-- `--no-clear` is deprecated. Use `reload` action instead.
-
-0.33.0
-------
-- Added `--scheme=[default|path|history]` option to choose scoring scheme
-    - (Experimental)
-    - We updated the scoring algorithm in 0.32.0, however we have learned that
-      this new scheme (`default`) is not always giving the optimal result
-    - `path`: Additional bonus point is only given to the characters after
-      path separator. You might want to choose this scheme if you have many
-      files with spaces in their paths.
-    - `history`: No additional bonus points are given so that we give more
-      weight to the chronological ordering. This is equivalent to the scoring
-      scheme before 0.32.0. This also sets `--tiebreak=index`.
-- ANSI color sequences with colon delimiters are now supported.
-  ```sh
-  printf "\e[38;5;208mOption 1\e[m\nOption 2" | fzf --ansi
-  printf "\e[38:5:208mOption 1\e[m\nOption 2" | fzf --ansi
-  ```
-- Support `border-{up,down}` as the synonyms for `border-{top,bottom}` in
-  `--preview-window`
-- Added support for ANSI `strikethrough`
-  ```sh
-  printf "\e[9mdeleted" | fzf --ansi
-  fzf --color fg+:strikethrough
-  ```
-
-0.32.1
-------
-- Fixed incorrect ordering of `--tiebreak=chunk`
-- fzf-tmux will show fzf border instead of tmux popup border (requires tmux 3.3)
-  ```sh
-  fzf-tmux -p70%
-  fzf-tmux -p70% --color=border:bright-red
-  fzf-tmux -p100%,60% --color=border:bright-yellow --border=horizontal --padding 1,5 --margin 1,0
-  fzf-tmux -p70%,100% --color=border:bright-green --border=vertical
-
-  # Key bindings (CTRL-T, CTRL-R, ALT-C) will use these options
-  export FZF_TMUX_OPTS='-p100%,60% --color=border:green --border=horizontal --padding 1,5 --margin 1,0'
-  ```
-
-0.32.0
-------
-- Updated the scoring algorithm
-    - Different bonus points to different categories of word boundaries
-      (listed higher to lower bonus point)
-        - Word after whitespace characters or beginning of the string
-        - Word after common delimiter characters (`/,:;|`)
-        - Word after other non-word characters
-      ```sh
-      # foo/bar.sh` is preferred over `foo-bar.sh` on `bar`
-      fzf --query=bar --height=4 << EOF
-      foo-bar.sh
-      foo/bar.sh
-      EOF
-      ```
-- Added a new tiebreak `chunk`
-    - Favors the line with shorter matched chunk. A chunk is a set of
-      consecutive non-whitespace characters.
-    - Unlike the default `length`, this scheme works well with tabular input
-      ```sh
-      # length prefers item #1, because the whole line is shorter,
-      # chunk prefers item #2, because the matched chunk ("foo") is shorter
-      fzf --height=6 --header-lines=2 --tiebreak=chunk --reverse --query=fo << "EOF"
-      N | Field1 | Field2 | Field3
-      - | ------ | ------ | ------
-      1 | hello  | foobar | baz
-      2 | world  | foo    | bazbaz
-      EOF
-      ```
-    - If the input does not contain any spaces, `chunk` is equivalent to
-      `length`. But we're not going to set it as the default because it is
-      computationally more expensive.
-- Bug fixes and improvements
-
 0.31.0
 ------
 - Added support for an alternative preview window layout that is activated
