This is an old command that is mostly equivalent to git-log. In fact, the man page for git-whatchanged says:

New users are encouraged to use git-log(1) instead.

The difference is that git-whatchanged shows you the changed files in their raw format which can be useful if you know what you are looking for.

See man git-whatchanged for more details.
