Overleaf

For immediate use, upload texchanges.sty beside the project’s main document and load it with \usepackage[review]{texchanges}.

Overleaf compiles projects with TeX Live. New CTAN packages become available through a later TeX Live and Overleaf update, so CTAN acceptance does not make the package immediately available on every Overleaf project.

The repository also includes an automatic comparison example. Its latexmkrc runs latexdiff against complete old and new revisions. Use explicit Texchanges commands when reviewers or editing tools need stable authors, IDs, comments, and decision statuses.
