I can't find an option to compare different versions of the same page, to see what the changes are.
This is especially important for localization, so localizers can implement the changes only, not having to compare the whole pages every time.
Is there a way to do so in WordPress?
The only workaround I can find require that the editor of the main language's pages save the HTML code of each page after each edit, which of course is prone to errors.
There is also no mechanism that I can see to allow a group of people to be notified of the changes made to a page.
