 CHANGELOG
 =========
 
+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:$GETTER" \
+      --bind "focus:+bg-transform-input-label:$GETTER" \
+      --bind "focus:+bg-transform-list-label:$GETTER" \
+      --bind "focus:+bg-transform-header-label:$GETTER" \
+      --bind "focus:+bg-transform-footer-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
+    hl:#719872 hl+:#719899
+    pointer:#e12672 marker:#e17899
+    header:#719872
+    spinner:#719899 info:#727100
+    prompt:#0099bd query:#616161
+    border:#e1e1e1
+  '
+  ```
+- Added `alt-bg` color to create striped lines to visually separate rows
+  ```sh
+  fzf --color bg:237,alt-bg:238,current-bg:236 --highlight-line
+
+  declare -f | perl -0777 -pe 's/^}\n/}\0/gm' |
+    bat --plain --language bash --color always |
+    fzf --read0 --ansi --reverse --multi \
+        --color bg:237,alt-bg:238,current-bg:236 --highlight-line
+  ```
+- [fish] Improvements in CTRL-R binding (@bitraid)
+    - You can trigger CTRL-R in the middle of a command to insert the selected item
+    - You can delete history items with SHIFT-DEL
+- Bug fixes and improvements
+    - Fixed unnecessary 100ms delay after `reload` (#4364)
+    - Fixed `selected-bg` not applied to colored items (#4372)
+
+0.61.3
+------
+- Reverted #4351 as it caused `tmux run-shell 'fzf --tmux'` to fail (#4559 #4560)
+- More environment variables for child processes (#4356)
+
+0.61.2
+------
+- Fixed panic when using header border without pointer/marker (@phanen)
+- Fixed `--tmux` option when already inside a tmux popup (@peikk0)
+- Bug fixes and improvements in CTRL-T binding of fish (#4334) (@bitraid)
+- Added `--no-tty-default` option to make fzf search for the current TTY device instead of defaulting to `/dev/tty` (#4242)
+
+0.61.1
+------
+- Disable bracketed-paste mode on exit. This fixes issue where pasting breaks after running fzf on old bash versions that don't support the mode.
+
+0.61.0
+------
+- Added `--ghost=TEXT` to display a ghost text when the input is empty
+  ```sh
+  # Display "Type to search" when the input is empty
+  fzf --ghost "Type to search"
+  ```
+- Added `change-ghost` and `transform-ghost` actions for dynamically changing the ghost text
+- Added `change-pointer` and `transform-pointer` actions for dynamically changing the pointer sign
+- Added `r` flag for placeholder expression (raw mode) for unquoted output
+- Bug fixes and improvements
+
+0.60.3
+------
+- Bug fixes and improvements
+    - [fish] Enable multiple history commands insertion (#4280) (@bitraid)
+    - [walker] Append '/' to directory entries on MSYS2 (#4281)
+    - Trim trailing whitespaces after processing ANSI sequences (#4282)
+    - Remove temp files before `become` when using `--tmux` option (#4283)
+    - Fix condition for using item numlines cache (#4285) (@alex-huff)
+    - Make `--accept-nth` compatible with `--select-1` (#4287)
+    - Increase the query length limit from 300 to 1000 (#4292)
+    - [windows] Prevent fzf from consuming user input while paused (#4260)
+
+0.60.2
+------
+- Template for `--with-nth` and `--accept-nth` now supports `{n}` which evaluates to the zero-based ordinal index of the item
+- Fixed a regression that caused the last field in the "nth" expression to be trimmed when a regular expression delimiter is used
+    - Thanks to @phanen for the fix
+- Fixed 'jump' action when the pointer is an empty string
+
+0.60.1
+------
+- Bug fixes and minor improvements
+    - Built-in walker now prints directory entries with a trailing slash
+    - Fixed a bug causing unexpected behavior with [fzf-tab](https://github.com/Aloxaf/fzf-tab). Please upgrade if you use it.
+- Thanks to @alexeisersun, @bitraid, @Lompik, and @fsc0 for the contributions

     \fR
 
+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.

 .SS PREVIEW BINDING
 
 With \fBpreview(...)\fR action, you can specify multiple different preview
