SRI-CSL/latextrack
LaTeX Track Changes shows changes over time for a .tex file that has its history stored in a git or svn repository. The user can customize how to view the changes: limited to certain authors or by revision or date among other filters. An Emacs mode provides the user interface. Plug-ins for other editors (such as TeXShop or Atom) are planned.
