Minecarts and such would be 0.34.08. Since then, we got -
* World activation - creatures now get born, married, armies attack sites, and people die off-site and assume entity positions as needed.
* Adventure mode visitable forest retreats, dark towers, and mountain halls (and spoiler sites as well).
* Multitile trees, and a few tons of plants.
* Fortress retirement (and unretirement)
* Adventure mode climbing, jumping, and tracking, and updated movement/stealth mechanics.
* Combat has threat levels now, differentiating between fisticuffs and lethal combat among others
* Adventure mode conversation and recruitment overhaul - it's more of a action/reaction now, and NPCs talk among themselves (quite a lot)
* The old thoughts system was replaced with an circumstance/emotion system that tracks stresses.
* Civilizations have values now that lead to individual goals
* Certain creatures can now be gelded (neutered), and reproduction requires contact.
* Job priorities got reworked and should get more important jobs quicker now. There's also a Do it now option for building tasks (workshops/levers)
* Designations can be given priorities from 1 to 7 (1 most important, 7 least), and can be places as markers (and be toggled).
* Mining designations can be switched to valuable stones only and be set to follow veins automatically.
* Wall/floor/road building uses a skill-less labor rather than masonry/carpentry etc.
* Haulers can generally carry multiple small items.
