Oh well, whatever changes in the units/technology, at least they are moddable.
The AI improvements are most welcome, as always.
I say this yet again: Using diplomatic score for a wide range of purposes, from creating a royal marriage with a new partner to researching new ship rigging to diploannexin now, is grossly unrealistic and disbalancing.

You don't say? And it took only a mere 8 months after game release for this feeling to accumulate.
Early colonizers already have an advantage in their ideas and in their geographical locations. They just won't be as able in the player's hand to lock the new world down at a far higher pace than was done in history.
