  (Huge thanks to \ 
[BACKERS.md](https://github.com/junegunn/junegunn/blob/main/BACKERS.md)!)

0.26.0
------
- Added support for fixed header in preview window
  ```sh
  # Display top 3 lines as the fixed header
  fzf --preview 'bat --style=header,grid --color=always {}' --preview-window '~3'
  ```
- More advanced preview offset expression to better support the fixed header
  ```sh
  # Preview with bat, matching line in the middle of the window below
  # the fixed header of the top 3 lines
  #
  #   ~3    Top 3 lines as the fixed header
  #   +{2}  Base scroll offset extracted from the second field
  #   +3    Extra offset to compensate for the 3-line header
  #   /2    Put in the middle of the preview area
  #
  git grep --line-number '' |
    fzf --delimiter : \
        --preview 'bat --style=full --color=always --highlight-line {2} {1}' \
        --preview-window '~3:+{2}+3/2'
  ```
- Added `select` and `deselect` action for unconditionally selecting or
  deselecting a single item in `--multi` mode. Complements `toggle` action.
- Sigificant performance improvement in ANSI code processing
- Bug fixes and improvements
- Built with Go 1.16

0.25.1
------
- Added `close` action
    - Close preview window if open, abort fzf otherwise
- Bug fixes and improvements

0.25.0
------
- Text attributes set in `--color` are not reset when fzf sees another
  `--color` option for the same element. This allows you to put custom text
  attributes in your `$FZF_DEFAULT_OPTS` and still have those attributes
  even when you override the colors.

  ```sh
  # Default colors and attributes
  fzf

  # Apply custom text attributes
  export FZF_DEFAULT_OPTS='--color \ 
fg+:italic,hl:-1:underline,hl+:-1:reverse:underline'

  fzf

  # Different colors but you still have the attributes
  fzf --color hl:176,hl+:177

  # Write "regular" if you want to clear the attributes
  fzf --color hl:176:regular,hl+:177:regular
  ```
- Renamed `--phony` to `--disabled`
- You can dynamically enable and disable the search functionality using the
  new `enable-search`, `disable-search`, and `toggle-search` actions
- You can assign a different color to the query string for when search is disabled
  ```sh
  fzf --color query:#ffffff,disabled:#999999 --bind space:toggle-search
  ```
- Added `last` action to move the cursor to the last match
    - The opposite action `top` is renamed to `first`, but `top` is still
      recognized as a synonym for backward compatibility
- Added `preview-top` and `preview-bottom` actions
- Extended support for alt key chords: alt with any case-sensitive single character
  ```sh
  fzf --bind alt-,:first,alt-.:last
  ```

0.24.4
------
- Added `--preview-window` option `follow`
  ```sh
  # Preview window will automatically scroll to the bottom
  fzf --preview-window follow --preview 'for i in $(seq 100000); do
    echo "$i"
    sleep 0.01
    (( i % 300 == 0 )) && printf "\033[2J"
  done'
  ```
- Added `change-prompt` action
  ```sh
  fzf --prompt 'foo> ' --bind $'a:change-prompt:\x1b[31mbar> '
  ```
- Bug fixes and improvements

0.24.3
------
- Added `--padding` option
  ```sh
  fzf --margin 5% --padding 5% --border --preview 'cat {}' \
      --color bg:#222222,preview-bg:#333333
  ```

0.24.2
------
- Bug fixes and improvements

0.24.1
------
- Fixed broken `--color=[bw|no]` option

0.24.0
------
- Real-time rendering of preview window
  ```sh
  # fzf can render preview window before the command completes
  fzf --preview 'sleep 1; for i in $(seq 100); do echo $i; sleep 0.01; done'

  # Preview window can process ANSI escape sequence (CSI 2 J) for clearing the \ 
display
  fzf --preview 'for i in $(seq 100000); do
    (( i % 200 == 0 )) && printf "\033[2J"
    echo "$i"
    sleep 0.01
  done'
  ```
- Updated `--color` option to support text styles
  - `regular` / `bold` / `dim` / `underline` / `italic` / `reverse` / `blink`
    ```sh
    # * Set -1 to keep the original color
    # * Multiple style attributes can be combined
    # * Italic style may not be supported by some terminals
    rg --line-number --no-heading --color=always "" |
      fzf --ansi --prompt "Rg: " \
          --color fg+:italic,hl:underline:-1,hl+:italic:underline:reverse:-1 \
          --color pointer:reverse,prompt:reverse,input:159 \
          --pointer '  '
    ```
- More `--border` options
  - `vertical`, `top`, `bottom`, `left`, `right`
  - Updated Vim plugin to use these new `--border` options
    ```vim
    " Floating popup window in the center of the screen
    let g:fzf_layout = { 'window': { 'width': 0.9, 'height': 0.6 } }

    " Popup with 100% width
    let g:fzf_layout = { 'window': { 'width': 1.0, 'height': 0.5, 'border': \ 
'horizontal' } }

    " Popup with 100% height
    let g:fzf_layout = { 'window': { 'width': 0.5, 'height': 1.0, 'border': \ 
'vertical' } }

    " Similar to 'down' layout, but it uses a popup window and doesn't \ 
affect the window layout
    let g:fzf_layout = { 'window': { 'width': 1.0, 'height': 0.5, 'yoffset': \ 
1.0, 'border': 'top' } }

    " Opens on the right;
    "   'highlight' option is still supported but it will only take the \ 
foreground color of the group
    let g:fzf_layout = { 'window': { 'width': 0.5, 'height': 1.0, 'xoffset': \ 
1.0, 'border': 'left', 'highlight': 'Comment' } }
    ```
- To indicate if `--multi` mode is enabled, fzf will print the number of
  selected items even when no item is selected
  ```sh
  seq 100 | fzf
    # 100/100
  seq 100 | fzf --multi
    # 100/100 (0)
  seq 100 | fzf --multi 5
    # 100/100 (0/5)
  ```
