Version 3.3
- Fixed: Square Rigging no longer hanging, it is a prereq for Steam Power.
- Changed: To balance the above extra connection, one was also added to Sanitation and Economics.
- Changed: An additional connection for Military Engineering, Metal Casting, and Siege Tactics. This makes slightly harder to progress via a domination path and allows a bit more time for others to up their defenses.

Version 3.2
- Fixed: (GS only) Mass Production is no longer a leaf - restored the vanilla connection to Industrialization.

Version 3.1
- Updated for June 2019 Patch: Adjustments to Stirrups and Chemistry.
- Changed: The AffectsSavedGames flag is now set to 1 to better support MP games.

Version 3.0
- Updated for Gathering Storm.
- Removed new placement for Tier1 governments due to an issue with missing Diplo policies when going first for Classical Republic.

Version 2.4
- Civics Tree has additional dependencies to limit beelining a bit more and achieve better balance.
- Added an optional placement for some governments (see screenshot). This is disabled by default.
