   ```
+- 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
