I have prepared a scientific manuscript for a Springer journal in LaTeX (The Springer template defines "svjour3" document class). After a review process, the editor ask me to change some parts of the paper and submit again for the second review process. In Microsoft Word, revising is defined as "track change". This feature highlights the changes within the document. I just want to know if LaTeX has a similar feature like track change in MS Word?
If not, what's the best way to highlight changes in a LaTeX document?
