 CHANGELOG
 =========
 
+0.66.0
+------
+
+### Introducing "raw" mode
+
+This version introduces a new "raw" mode (named so because it shows the list
+"unfiltered"). In raw mode, non-matching items stay in their original positions,
+but appear dimmed. This allows you see surrounding items of a match and better
+understand the context of it. You can enable raw mode by default with `--raw`,
+but it's often more useful when toggled dynamically with the `toggle-raw`
+action.
+
+```sh
+tree | fzf --reverse --bind alt-r:toggle-raw
+```
+
+While non-matching items are displayed in a dimmed color, they are treated just
+like matching items, so you place the cursor on them and perform any action. If
+you prefer to navigate only through matching items, use the `down-match` and
+`up-match` actions, which are from now on bound to `CTRL-N` and `CTRL-P`
+respectively, and also to `ALT-DOWN` and `ALT-UP`.
+
+| Key        | Action       | With `--history` |
+| :--        | :--          | :--              |
+| `down`     | `down`       |                  |
+| `up`       | `up`         |                  |
+| `ctrl-j`   | `down`       |                  |
+| `ctrl-k`   | `up`         |                  |
+| `ctrl-n`   | `down-match` | `next-history`   |
+| `ctrl-p`   | `up-match`   | `prev-history`   |
+| `alt-down` | `down-match` |                  |
+| `alt-up`   | `up-match`   |                  |
+
+> [!NOTE]
+> `CTRL-N` and `CTRL-P` are bound to `next-history` and `prev-history` when
+> `--history` option is enabled, so in that case, you'll need to manually bind
+> them, or use `ALT-DOWN` and `ALT-UP` instead.
+
+> [!TIP]
+> `up-match` and `down-match` are equivalent to `up` and `down` when not in
+> raw mode, so you can safely bind them to `up` and `arrow` keys if you prefer.
+> ```sh
+> fzf --bind up:up-match,down:down-match
+> ```
+
+#### Customizing the behavior
+
+In raw mode, the input list is presented in its original order, unfiltered, and
+your cursor will not move to the matching item automatically. Here are ways to
+customize the behavior.
+
+```sh
+# When the result list is updated, move the cursor to the item with the best score
+# (assuming sorting is not disabled)
+fzf --raw --bind result:best
+
+# Move to the first matching item in the original list
+# - $FZF_RAW is set to 0 when raw mode is enabled and the current item is a non-match
+# - $FZF_DIRECTION is set to either 'up' or 'down' depending on the layout direction
+fzf --raw --bind 'result:first+transform:[[ $FZF_RAW = 0 ]] && echo $FZF_DIRECTION-match'
+```
+
+#### Customizing the look
+
+##### Gutter
+
+To make the mode visually distinct, the gutter column is rendered in a dashed
+line using `▖` character. But you can customize it with the `--gutter-raw CHAR`
+option.
+
+```sh
+# Use a thinner gutter instead of the default dashed line
+fzf --bind alt-r:toggle-raw --gutter-raw ▎
+```
+
+##### Color and style of non-matching items
+
+Non-matching items are displayed in a dimmed color by default, but you can
+change it with the `--color nomatch:...` option.
+
+```sh
+fzf --raw --color nomatch:red
+fzf --raw --color nomatch:red:dim
+fzf --raw --color nomatch:red:dim:strikethrough
+fzf --raw --color nomatch:red:dim:strikethrough:italic
+```
+
+For colored input, dimming alone may not be enough, and you may prefer to remove
+colors entirely. For that case, a new special style attribute `strip` has been
+added.
+
+```sh
+fd --color always | fzf --ansi --raw --color nomatch:dim:strip:strikethrough
+```
+
+#### Conditional actions for raw mode
+
+You may want to perform different actions depending on whether the current item
+is a match or not. For that, fzf now exports `$FZF_RAW` environment variable.
+
+It's:
+
+- Undefined if raw mode is disabled
+- `1` if the current item is a match
+- `0` otherwise
+
+```sh
+# Do not allow selecting non-matching items
+fzf --raw --bind 'enter:transform:[[ ${FZF_RAW-1} = 1 ]] && echo accept || echo bell'
+```
+
+#### Leveraging raw mode in shell integration
+
+The `CTRL-R` binding (command history) now lets you toggle raw mode with `ALT-R`.
+
+### Style changes
+
+This version includes a few minor updates to fzf's classic visual style:
+
+- The gutter column is now narrower, rendered with the left-half block character (`▌`).
+- Markers no longer use background colors.
+- The `--color base16` theme (alias: `16`) has been updated for better compatibility with both dark and light themes.
+
+### Added options
+
+#### `--gutter CHAR`
+
+The gutter column can now be customized using `--gutter CHAR` and styled with
+`--color gutter:...`. Examples:
+
+```sh
+# Right-aligned gutter
+fzf --gutter '▐'
+
+# Even thinner gutter
+fzf --gutter '▎'
+
+# Yellow checker pattern
+fzf --gutter '▚' --color gutter:yellow
+
+# Classic style
+fzf --gutter ' ' --color gutter:reverse
+```
+
+#### `--gutter-raw CHAR`
+
+As noted above, the `--gutter-raw CHAR` option was also added for customizing the gutter column in raw mode.
+
+### Added actions
+
+| Action        | Description                                                                                       |
+| ---           | ---                                                                                               |
+| `up-match`    | Move up to the matching item; identical to `up` if raw mode is disabled                           |
+| `down-match`  | Move down to the matching item; identical to `down` if raw mode is disabled                       |
+| `toggle-raw`  | Toggle raw mode                                                                                   |
+| `enable-raw`  | Enable raw mode                                                                                   |
+| `disable-raw` | Disable raw mode                                                                                  |
+| `best`        | Move to the first matching item with the best score; identical to `first` if raw mode is disabled |
+
+### Added environment variable
+
+`$FZF_DIRECTION` is now exported to child processes, indicating the list direction of the current layout.
+
+- `up` for the default layout
+- `down` for `reverse` or `reverse-list`
+
+This simplifies writing transform actions involving layout-dependent actions
+like `{up,down}-match`, `{up,down}-selected`, and `toggle+{up,down}`.
+
+```sh
+fzf --raw --bind 'result:first+transform:[[ $FZF_RAW = 0 ]] && echo $FZF_DIRECTION-match'
+```
+
+### Breaking changes
+
+#### Hiding the gutter column
+
+In the previous versions, the recommended way to hide the gutter column was to
+set `--color gutter:-1`. That's because the gutter column was just a space
+character, reversed. But now that it's using a visible character (`▌`), applying
+the default color is no longer enough to hide it. Instead, you can set it to
+a space character.
+
+```sh
+# Hide the gutter column
+fzf --gutter ' '
+
+# Classic style
+fzf --gutter ' ' --color gutter:reverse
+```
+
+#### `--color` option
+
+In the previous versions, some elements had default style attributes applied and
+you would have to explicitly unset them with `regular` attribute if you wanted
+to reset them. This is no longer needed now, as the default style attributes
+are applied only when you do not specify any color or style for that element.
+
+```sh
+# No 'dim', just red and italic.
+fzf --ghost 'Type to search' --color ghost:red:italic
+```
+
+#### Compatibility changes
+
+Starting with this release, fzf is built with Go 1.23. Support for some old OS versions has been dropped.
+
+See https://go.dev/wiki/MinimumRequirements.
+
+0.65.2
+------
+- Bug fixes and improvements
+    - Fix incorrect truncation of `--info-command` with `--info=inline-right` (#4479)
+    - [install] Support old uname in macOS (#4492)
+    - [bash 3] Fix `CTRL-T` and `ALT-C` to preserve the last yank (#4496)
+    - Do not unset `FZF_DEFAULT_*` variables when using winpty (#4497) (#4400)
+    - Fix rendering of items with tabs when using a non-default ellipsis (#4505)
+- **This is the final release to support Windows 7.**
+    - Future versions will be built with the latest Go toolchain, which has dropped support for Windows 7.
+
+0.65.1
+------
+- Fixed incorrect `$FZF_CLICK_HEADER_WORD` and `$FZF_CLICK_FOOTER_WORD` when the header or footer contains ANSI escape sequences and tab characters.
+- Fixed a bug where you cannot unset the default `--nth` using `change-nth` action.
+- Fixed a highlighting bug when using `--color fg:dim,nth:regular` pattern over ANSI-colored items.
+
+0.65.0
+------
+- Added `click-footer` event that is triggered when the footer section is clicked. When the event is triggered, the following environment variables are set:
+    - `$FZF_CLICK_FOOTER_COLUMN` - clicked column (1-based)
+    - `$FZF_CLICK_FOOTER_LINE` - clicked line (1-based)
+    - `$FZF_CLICK_FOOTER_WORD` - the word under the cursor
+  ```sh
+  fzf --footer $'[Edit] [View]\n[Copy to clipboard]' \
+      --with-shell 'bash -c' \
+      --bind 'click-footer:transform:
+        [[ $FZF_CLICK_FOOTER_WORD =~ Edit ]] && echo "execute:vim \{}"
+        [[ $FZF_CLICK_FOOTER_WORD =~ View ]] && echo "execute:view \{}"
+        (( FZF_CLICK_FOOTER_LINE == 2 )) && (( FZF_CLICK_FOOTER_COLUMN < 20 )) &&
+            echo "execute-silent(echo -n \{} | pbcopy)+bell"
+      '
+  ```
+- Added `trigger(...)` action that triggers events bound to another key or event.
+  ```sh
+  # You can click on each key name to trigger the actions bound to that key
+  fzf --footer 'Ctrl-E: Edit / Ctrl-V: View / Ctrl-Y: Copy to clipboard' \
+      --with-shell 'bash -c' \
+      --bind 'ctrl-e:execute:vim {}' \
+      --bind 'ctrl-v:execute:view {}' \
+      --bind 'ctrl-y:execute-silent(echo -n {} | pbcopy)+bell' \
+      --bind 'click-footer:transform:
+        [[ $FZF_CLICK_FOOTER_WORD =~ Ctrl ]] && echo "trigger(${FZF_CLICK_FOOTER_WORD%:})"
+      '
+  ```
+    - You can specify a series of keys and events
+      ```sh
+      fzf --bind 'a:up,b:trigger(a,a,a)'
+      ```
+- Added support for `{*n}` and `{*nf}` placeholder.
+    - `{*n}` evaluates to the zero-based ordinal index of all matched items.
+    - `{*nf}` evaluates to the temporary file containing that.
+- Bug fixes and improvements
+    - [neovim] Fixed margin background color when `&winborder` is used (#4453)
+    - Fixed rendering error when hiding a preview window without border (#4465)
+    - fix(shell): check for mawk existence before version check (#4468)
+        - Thanks to @LangLangBart and @akinomyoga
+    - Fixed `--no-header-lines-border` behavior (08027e7a)
+
+0.64.0
+------
+- Added `multi` event that is triggered when the multi-selection has changed.
+  ```sh
+  fzf --multi \
+      --bind 'ctrl-a:select-all,ctrl-d:deselect-all' \
+      --bind 'multi:transform-footer:(( FZF_SELECT_COUNT )) && echo "Selected $FZF_SELECT_COUNT item(s)"'
+  ```
+- [Halfwidth and fullwidth alphanumeric and punctuation characters](https://en.wikipedia.org/wiki/Halfwidth_and_Fullwidth_Forms_(Unicode_block)) are now internally normalized to their ASCII equivalents to allow matching with ASCII queries.
+  ```sh
+  echo ＡＢＣ| fzf -q abc
+  ```
+- Renamed `clear-selection` action to `clear-multi` for consistency.
+    - `clear-selection` remains supported as an alias for backward compatibility.
+- Bug fixes
+    - Fixed a bug that could cause fzf to abort due to incorrect update ordering.
+    - Fixed a bug where some multi-selections were lost when using `exclude` or `change-nth`.
+
+0.63.0
+------
+_Release highlights: https://junegunn.github.io/fzf/releases/0.63.0/_
+
+- Added footer. The default border style for footer is `line`, which draws a single separator line.
+  ```sh
+  fzf --reverse --footer "fzf: friend zone forever"
+  ```
+  - Options
+      - `--footer[=STRING]`
+      - `--footer-border[=STYLE]`
+      - `--footer-label=LABEL`
+      - `--footer-label-pos=COL[:bottom]`
+  - Colors
+      - `footer`
+      - `footer-bg`
+      - `footer-border`
+      - `footer-label`
+  - Actions
+      - `change-footer`
+      - `transform-footer`
+      - `bg-transform-footer`
+      - `change-footer-label`
+      - `transform-footer-label`
+      - `bg-transform-footer-label`
+- `line` border style is now allowed for all types of border except for `--list-border`.
+  ```sh
+  fzf --height 50% --style full:line --preview 'cat {}' \
+      --bind 'focus:bg-transform-header(file {})+bg-transform-footer(wc {})'
+  ```
+- Added `{*}` placeholder flag that evaluates to all matched items.
+  ```bash
+  seq 10000 | fzf --preview "awk '{sum += \$1} END {print sum}' {*f}"
+  ```
+  - Use this with caution, as it can make fzf sluggish for large lists.
+- Added asynchronous transform actions with `bg-` prefix that run asynchronously in the background, along with `bg-cancel` action to cancel currently running `bg-transform` actions.
+  ```sh
+  # Implement popup that disappears after 1 second
+  #   * Use footer as the popup
+  #   * Use `bell` to ring the terminal bell
+  #   * Use `bg-transform-footer` to clear the footer after 1 second
+  #   * Use `bg-cancel` to cancel currently running background transform actions
+  fzf --multi --list-border \
+      --bind 'enter:execute-silent(echo -n {+} | pbcopy)+bell' \
+      --bind 'enter:+transform-footer(echo Copied {} to clipboard)' \
+      --bind 'enter:+bg-cancel+bg-transform-footer(sleep 1)'
+
+  # It's okay for the commands to take a little while because they run in the background
+  GETTER='curl -s http://metaphorpsum.com/sentences/1'
+  fzf --style full --border --preview : \
+      --bind "focus:bg-transform-header:$GETTER" \
+      --bind "focus:+bg-transform-footer:$GETTER" \
+      --bind "focus:+bg-transform-border-label:$GETTER" \
+      --bind "focus:+bg-transform-preview-label:$GETTER" \

+      --bind "focus:+bg-transform-ghost:$GETTER" \
+      --bind "focus:+bg-transform-prompt:$GETTER"
+  ```
+- Added support for full-line background color in the list section
+  ```sh
+  for i in $(seq 16 255); do
+    echo -e "\x1b[48;5;${i}m\x1b[0Khello"
+  done | fzf --ansi
+  ```
+- SSH completion enhancements by @akinomyoga
+- Bug fixes and improvements
+
+0.62.0
+------
+- Relaxed the `--color` option syntax to allow whitespace-separated entries (in addition to commas), making multi-line definitions easier to write and read
+  ```sh
+  # seoul256-light
+  fzf --style full --color='
+    fg:#616161 fg+:#616161
+    bg:#ffffff bg+:#e9e9e9 alt-bg:#f1f1f1

+A common mistake when writing a \fBtransform\fR action is not escaping
+placeholder expressions when passing them back to fzf. In the following
+example, if you don't escape \fB{}\fR, fzf will immediately replace it with the
+single-quoted string of the current item. This causes single quotes to appear
+in the header and footer, and the script will break if any item contains
+double-quote characters.

+.SS TRANSFORM IN THE BACKGROUND
+
+Transform actions are synchronous, meaning fzf becomes unresponsive while the
+command runs. To avoid this, each \fBtransform*\fR action has a corresponding
+\fBbg\-transform*\fR variant that runs in the background. Unless you need to
+chain multiple transform actions where later ones depend on earlier results,
+prefer using the \fBbg\fR variant. To cancel currently running background
+transform processes, use \fBbg\-cancel\fR action.
