You can make it backward-compatible with older versions by copying
the contents of the function save-some-buffers-root literally
to your code.  This call should work in older versions:

#+begin_src emacs-lisp
  (save-some-buffers
   t
   (let ((root (or (and (project-current) (project-root (project-current)))
                   default-directory)))
     (lambda () (file-in-directory-p default-directory root))))
#+end_src

Thanks, this is a useful package.  It uses the right strategy
to stash and unstash changes.  This is much better than committing
and undoing commits like we recently discussed in
https://lists.gnu.org/archive/html/emacs-devel/2021-08/msg00346.html
