2.8.6 Changes:
-------------------------------

Population required for every additional specialty district is reduced by 1. So a city can build another district at pop 3, 5, 7, 9 and so on. (was every 3 pop in base game).

With 2.8, eras are longer than in the base game and getting stuck for a long time in a dark age can really suck, therefore:
Citizen pressure (loyalty) for golden and heroic ages reduced to 1.25 (was 1.5)
Pressure from dark age increased to 0.75 (was 0.5).

Increased resource cost for units in the Medieval and later eras slightly.
Barracks and Stables now get +2 production to encourage AI to build them (was +1).
Gold cost of upgrading units increased to 150% of production cost, so highly promoted will be a bit more expensive to upgrade (was 100%).

Removed adjacency bonus for Commerical Hubs and Harbors of Gold from every 2 adjacent districts.
Harbors get +1 gold for every adjacent Camp.
Commercial Hubs now get +1 Gold for every adjacent Neighborhood.

Kurgan improvements now start with 2 Gold (was 1).
Kurgans provide +1 loyalty to city.

Pantheons:

Goddess of the Hunt providdes 2 Faith (was 1).

Metal Casting is slightly more expensive. Costs the same as Mass production.

Brazil's trait has been reworked again.
Now Campus, Commerical Hub and Theater Square receive +1 adjacency bonus for every 2 adjacent Rainforests. Holy sites are unchanged.

Updated texts in the Civilopedia to reflect some changes by the mod.
Updated texts for district projects to add more specific info about rewards.

Fixed: Submarines dealing minimal damage vs embarked units.
Fixed: Recon promotion combat bonuses should now preview correctly.
Fixed: Text for Aqueduct, Bath, Military Engineer, Builder etc.

Farms receive +1 Food for every 3 adjacent Marsh tiles.

Embarked strength for Medieval era is now 35 (was 40).
Galleys and Quadrireme receive +5 CS when attacking Coast tiles from Naval Tradition (and Iron surplus).
Brazil's Campuses no longer receive adjacency bonus for resources. Bonus from rainforests are quite enough.

Compatibility with JNR's "Stone rocks!" and probably compatibility with a lot of other mods is now implemented! Please report any incompatibility issues.

2.8.3 changes:

Spies should now be invisible to other Civs again. Turns out that "Team visibility" doesn't affect visibility of unit within team but rather visibility to players not in the team.

2.8.2 changes
----------------------

-------------------------------------

Finally 2.8 is uploaded and this is one of the biggest updates yet. A lot of changes have been made in a lot of different areas. A lot of inconsistencies and other issues have been dealt with. Far too much have been changed to list it all, but a few tidbits are written below:

Techs in Eras ahead are now twice as expensive (+40%). Techs in Eras behind are the same (-20%)

--CIVIC TREE
Embarked Units can now ignore cost of ocean tiles with Colonialism. (was Square rigging tech in 2.7.3).
Basically you're encouraged to use naval units to escort your embarked units across Oceans, until you get Colonialism.

Forts and other defensive improvements now provide housing, and some small yields.

Fixed a lot of issues with building improvements on resources with various features.

--BARBARIANS
Inspired by Angryr's Harsh Existence mod:
Barbarian tech level is now 75% of player's (was 50%)
Barbarian kills now give 2 XP after lvl 1 (was 1)

-- UNIT MAINTENANCE AND ATTRITION
Gold Maintenance costs are now increased for all units, scaling up with the Eras.
No extra maintenance costs from having units in enemy territory or embarked.
Instead, Combat units that are outside and not adjacent to owner's borders take 1 attrition damage per turn, unless the unit is inside a district or fort improvement.
And Combat units inside enemy territory and not adjacent to owner's borders take an additional 1 attrition damage per turn, unless the unit is inside a district or fort improvement. Recon units are excluded from this additional attrition.

-- SPECIFIC UNITS

All melee, anti-cavalry, light cavalry, heavy cavalry units and warrior monks now start with a ranged attack of 1 CS, and range 0. This allows these units to make ranged attacks if they acquire one of the ranged support units above.
AT-crew and Modern AT have also been converted into Support units. They grant escorting units a melee bonus vs. Tanks, Modern Armor, Mechanized Infantry and so on.
All recon units may now move after attacking.
All light cavalry units may now pillage for only 1 movement point.

Battering Ram and Siege Tower now grant the same bonus (full damage vs walls) and both work against Medieval Walls. They also grant combat bonuses to their escorting units.

Spies should now no longer become visible to players on your team, which should include emergency allies (?).

-- GOVERNMENTS

-- POLICY CARDS
Conscription and Levée en masse reduces maintenance costs but also reduce combat strength by a tiny amount.

-- RELIGION
Pressure from trade routes reduced to 0.5 for origin and destination.

--EMERGENCIES
