Is there any move on this? For documentation/educational purposes, I would definitely need a tool like this, but without PHP 7.1+ support it becomes tedious to generate a dependency graph for classes, since there's not many tools for this purpose...

@mamuz If you ever need help, can you give hints on where to start for people that never contributed to this project? 😉

will be fixed with next major
