 CHANGELOG
 =========
 
-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
