 CHANGELOG
 =========
 
+0.32.1
+------
+- Fixed incorrect ordering of `--tiebreak=chunk`
+- fzf-tmux will show fzf border instead of tmux popup border (requires tmux 3.3)
+  ```sh
+  fzf-tmux -p70%
+  fzf-tmux -p70% --color=border:bright-red
+  fzf-tmux -p100%,60% --color=border:bright-yellow --border=horizontal --padding 1,5 --margin 1,0
+  fzf-tmux -p70%,100% --color=border:bright-green --border=vertical
+
+  # Key bindings (CTRL-T, CTRL-R, ALT-C) will use these options
+  export FZF_TMUX_OPTS='-p100%,60% --color=border:green --border=horizontal --padding 1,5 --margin 1,0'
+  ```
+
+0.32.0
+------
+- Updated the scoring algorithm
+    - Different bonus points to different categories of word boundaries
+      (listed higher to lower bonus point)
+        - Word after whitespace characters or beginning of the string
+        - Word after common delimiter characters (`/,:;|`)
+        - Word after other non-word characters
+      ```sh
+      # foo/bar.sh` is preferred over `foo-bar.sh` on `bar`
+      fzf --query=bar --height=4 << EOF
+      foo-bar.sh
+      foo/bar.sh
+      EOF
+      ```
+- Added a new tiebreak `chunk`
+    - Favors the line with shorter matched chunk. A chunk is a set of
+      consecutive non-whitespace characters.
+    - Unlike the default `length`, this scheme works well with tabular input
+      ```sh
+      # length prefers item #1, because the whole line is shorter,
+      # chunk prefers item #2, because the matched chunk ("foo") is shorter
+      fzf --height=6 --header-lines=2 --tiebreak=chunk --reverse --query=fo << "EOF"
+      N | Field1 | Field2 | Field3
+      - | ------ | ------ | ------
+      1 | hello  | foobar | baz
+      2 | world  | foo    | bazbaz
+      EOF
+      ```
+    - If the input does not contain any spaces, `chunk` is equivalent to
+      `length`. But we're not going to set it as the default because it is
+      computationally more expensive.
+- Bug fixes and improvements
+
 0.31.0
 ------
 - Added support for an alternative preview window layout that is activated
