This version of the list only lists the actual changes. It also does not list the changes in the number of required ascension perks because that can be discerned from the perk being listed as basic, intermediate, or advanced.
Basic perks have no requirements and add related permanent research options, typically a tier 2 technology. Intermediate perks require you to already have two basic perk and have some technological requirements, but in several cases a basic perk will give you the requirement as a research option. Advanced perks require you to have four basic or intermediate perks selected first. They have technological requirements, but they will often be less strict than in the unmodded game.
Additionally maximum possible leader level cap is no longer limited to 10 like in the base game. There is effectively no more fixed upper limit anymore. This was necessary to make Transcendent Learning actually work properly and as a side effect the Philosopher King civic and Talented species trait should no longer be useless either. This effect is fully compatible with any other mods that also remove the upper limit of the leader level cap.
