 CHANGELOG
 =========

+0.57.0
+------
+- You can now resize the preview window by dragging the border
+- Built-in walker improvements
+    - `--walker-root` can take multiple directory arguments. e.g. `--walker-root include src lib`
+    - `--walker-skip` can handle multi-component patterns. e.g. `--walker-skip target/build`
+- Removed long processing delay when displaying images in the preview window
+- `FZF_PREVIEW_*` environment variables are exported to all child processes (#4098)
+- Bug fixes in fish scripts
+
+0.56.3
+------
+- Bug fixes in zsh scripts
+    - fix(zsh): handle backtick trigger edge case (#4090)
+    - revert(zsh): remove 'fc -RI' call in the history widget (#4093)
+    - Thanks to @LangLangBart for the contributions
+
+0.56.2
+------
+- Bug fixes
+    - Fixed abnormal scrolling behavior when `--wrap` is set (#4083)
+    - [zsh] Fixed warning message when `ksh_arrays` is set (#4084)
+
+0.56.1
+------
+- Bug fixes and improvements
+    - Fixed a race condition which would cause fzf to present stale results after `reload` (#4070)
+    - `page-up` and `page-down` actions now work correctly with multi-line items (#4069)
+    - `{n}` is allowed in `SCROLL` expression in `--preview-window` (#4079)
+    - [zsh] Fixed regression in history loading with shared option (#4071)
+    - [zsh] Better command extraction in zsh completion (#4082)
+- Thanks to @LangLangBart, @jaydee-coder, @alex-huff, and @vejkse for the contributions
+
+0.56.0
+------
+- Added `--gap[=N]` option to display empty lines between items.
+    - This can be useful to visually separate adjacent multi-line items.
+      ```sh
+      # All bash functions, highlighted
+      declare -f | perl -0777 -pe 's/^}\n/}\0/gm' |
+        bat --plain --language bash --color always |
+        fzf --read0 --ansi --reverse --multi --highlight-line --gap
+      ```
+    - Or just to make the list easier to read. For single-line items, you probably want to set `--color gutter:-1` as well to hide the gutter.
+      ```sh
+      fzf --info inline-right --gap --color gutter:-1
+      ```
+- Added `noinfo` option to `--preview-window` to hide the scroll indicator in the preview window
+- Bug fixes
+    - Thanks to @LangLangBart, @akinomyoga, and @charlievieth for fixing the bugs
+
+0.55.0
+------
+_Release highlights: https://junegunn.github.io/fzf/releases/0.55.0/_
+
+- Added `exact-boundary-match` type to the search syntax. When a search term is single-quoted, fzf will search for the exact occurrences of the string with both ends at word boundaries.
+  ```sh
+  fzf --query "'here'" << EOF
+  come here
+  not there
+  EOF
+  ```
+- [bash] Fuzzy path completion is enabled for all commands
+    - 1. If the default completion is not already set
+    - 2. And if the current bash supports `complete -D` option
+    - However, fuzzy completion for some commands can be "dynamically" disabled by the dynamic completion loader
+    - See the comment in `__fzf_default_completion` function for more information
+- Comments are now allowed in `$FZF_DEFAULT_OPTS` and `$FZF_DEFAULT_OPTS_FILE`
+  ```sh
+  export FZF_DEFAULT_OPTS='
+    # Layout options
+    --layout=reverse
+    --info=inline-right   # Show info on the right side of the prompt line
+    # ...
+  '
+  ```
+- Hyperlinks (OSC 8) are now supported in the preview window and in the main window
+  ```sh
+  printf '<< \e]8;;http://github.com/junegunn/fzf\e\\Link to \e[32mfz\e[0mf\e]8;;\e\\ >>' | fzf --ansi
+
+  fzf --preview "printf '<< \e]8;;http://github.com/junegunn/fzf\e\\Link to \e[32mfz\e[0mf\e]8;;\e\\ >>'"
+  ```
+- The default `--ellipsis` is now `··` instead of `..`.
+- [vim] A spec can have `exit` callback that is called with the exit status of fzf
+    - This can be used to clean up temporary resources or restore the original state when fzf is closed without a selection
+- Fixed `--tmux bottom` when the status line is not at the bottom
+- Fixed extra scroll offset in multi-line mode (`--read0` or `--wrap`)
+- Added fallback `ps` command for `kill` completion on Cygwin
+
+0.54.3
+------
+- Fixed incompatibility of adaptive height specification and 'start:reload'
+  ```sh
+  # A regression in 0.54.0 would cause this to fail
+  fzf --height '~100%' --bind 'start:reload:seq 10'
+  ```
+- Environment variables are now available to `$FZF_DEFAULT_COMMAND`
+  ```sh
+  FZF_DEFAULT_COMMAND='echo $FZF_QUERY' fzf --query foo
+  ```
+
+0.54.2
+------
+- Fixed incorrect syntax highlighting of truncated multi-line entries
+- Updated GoReleaser to 2.1.0 to simplify notarization of macOS binaries
+    - macOS archives will be in `tar.gz` format instead of `zip` format since we no longer notarize the zip files but binaries
+- (Windows) Reverted a mintty fix in 0.54.0
+    - As a result, mouse may not work on mintty in fullscreen mode. However, fzf will correctly read non-ASCII input in fullscreen mode (`--no-height`).
+    - fzf unfortunately cannot read non-ASCII input when not in fullscreen mode on Windows. So if you need to input non-ASCII characters, add `--no-height` to your `$FZF_DEFAULT_OPTS`.
+    - Any help in fixing this issue will be appreciated (#3799, #3847).
+
 0.54.1
