Hey Jaxas,
That course is almost 2 years old, and even though it's still completely relevant and useful to anyone making a game now, the weeks I would need to update the course with this content would be a massive undertaking.
This engine could be thought of as an extension of that course though, and the descriptions in the read me outline how everything works, so if you have knowledge of the Udemy course, you would be very well placed to understand the code in this.
So even though I keep the Tile Based course current, and have recently recorded new sections to ensure it is GMS2.3 compatible, I'm currently working on my next course, so do not have the time to add new content into that course.
Thanks for the question though.
