Version 2.5.00-PR7 (The Evil Beneath):
This update only effects the 2.0 closed beta.
Influence Tracking:
- Orc influence tracking now takes account of the powers of The Evil Beneath.
- Orc influence tracking now takes account of armies and settlements killed and razed, respectively, by The Evil Beneath.

Great Construction:
- The utility score for the orcs' Great Construction national action no longer considers adjacent orc camps as a positive factor for orcish mines.
- - This is because they have no army type, and therefore do not benefit from their neighbours' orcish industry.
- The utility of building mines has been reduced from 80 to 40. This functionally lowers the maximum number of mines that orcs will try to maintain from 8 to 4.

God Specific Tenet:
- Implemented "Secrets of Destruction" god specific tenet for The Evil beneath.
- - At -1, orc industry will produce explosives, stored in the "Explosive Stockpile" property, which orc armies will use to quickly raze settlements.
- - At -2, orc armies will also use explosives in army battle, dealing damage to all armies on the opposing side and causing devastation.

Version 2.5.00-PR6 (Pathfinding Fix):
- (2.0 closed beta) Updated to account for Community Library Update (Version 2.0.00-PR10).

- (2.0 closed beta) Orc Hordes created as a result of civil wars will now start with knowledge of the underground if their parent orc horde had it.

Version 2.5.00-PR1 (Experimental):
This update provides experimental support for the closed-beta for the upcoming underground expansion. As far as I can tell, all features are functioning, but there may be interactions from new game content that are not yet accounted for or properly handled.

The following change-log applies only when suing the closed-beta branch of the game:
- Updated civil war logic to prevent crashes when sorting camps by specialism.
- New orc camp specialism (specialism 6), has been introduced; Orc Mines.
- - Despite having only 1 function (to allow orcs to move underground), hosting no army, and having no special features, this still counts as a specialised camp for purposes of building Great Halls, choosing a new capital, performing challenges, and so on.

Version 2.4.05 (Dockyard Brawler Improvement):
- Improved target acquisition rules for Dockyard Brawler minion trait when the minion is held by an agent of a good society.

Version 2.4.03 (Fixes):
- The Raid Outpost challenge in orc camps will now consider intolerance, and ignore those that they are totally tolerant of.
- - When a player agent uses this challenge, it will always target outposts of societies that are not dark, even if the orc camp belongs to an orc culture with intolerance +2.
- The Dockyard Brawler minion trait will no longer disrupt those who are lying low.
- The Dockyard Brawler minion trait will not disrupt player agents if the agent with the minion with the Dockyard Brawler trait is a player agent themselves or belongs to a dark society.
