After upgrading to 9.5.3, I am getting warnings such as this, which I
suspect are due to org-fold.et.

Warning (comp): org-fold.el:834:27: Warning: Unused lexical variable
`org-hide-macro-markers' Disable showing Disable logging

Warning (comp): ox.el:79:1: Warning: the function ‘org-at-heading-p’ might

Is org-fold.el documented already? Any pointers to what might be causing
the above?

Thanks,
