0.55.0

Only requiring '-suffix in --exact mode is confusing and not
straightforward. Requiring '-prefix in --exact mode means that
the users can experience unintended mode switches while typing.

e.g.
     'it   -> fuzzy (many results)
     'it'  -> boundary (few results)
     'it's -> fuzzy (many results)

However, user who intends to input a boundary query should not be
interested in the intermediate results, and the number of matches
decreases as she types, so it should be okay.

On the other hand, user who does intend to type "it's" will be surprised
by the sudden decrease of the match count, but eventually get the right
result.

 CHANGELOG
 =========
 
+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 and 'start:reload'
+- 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
