A few previously disabled gameplay mechanics have been re-enabled, along with some brand new mechanics.
Some balance changes to Building costs and Productions have also been made.

GAMEPLAY

• New mechanic: Entropy
  • Entropy causes resources in stockpiles to slowly decay over time, higher Entropy makes the decay faster
    
  • Entropy is increased by high population and number of buildings
    
  • Some buildings/goods reduce Entropy
    
  
  
• New mechanic: Transfer capacity
  • Moving goods around now requires Transfer capacity
    
  • Too little Transfer capacity means goods can't get to where they're needed
    
  • Some buildings increase Transfer capacity
    
  
  
• New mechanic: Production chains
  • Buildings can take goods they need directly from adjacent buildings
    
  • Goods transferred directly between adjacent buildings in this way does not use Transfer capacity
    
  
  
• Stockpile building has been renamed to Horreum
  
• Citadel now provides -30% Global Entropy
  
• Citadel now provides -30% Global Upkeep
  
• Citadel now provides 5 Transfer capacity
  
• Horreum now provides 1 Transfer capacity
  
• Max stockpile gained from Citadel reduced to 50 from 250
  
• Max stockpile gained from Horreum reduced to 50 from 250
  
• Farms now produce Vegetables
  
• Farms now produce Wood
  
• Certain resources now have an inherent decay over time (ex. Vegetables) independent of Entropy
  
• Unwanted buildings can now be razed
  
• Several new goods and resources added
  
• Some new building modifiers
  
• The cost of most buildings have been changed
  
  

INTERFACE

• Building stockpiles no longer appear empty if there's active production
  
• It is now possible to right-click in addition to left-click in order to "go back" to planet view after selecting a building
  
• Greatly improved UI responsiveness to left- or right-clicking
  
• Planetary stockpile view is now sorted alphabetically
  
  

BUGS

• Fixed unknown modifier on Stockpile
  
• Fixed certain productions not consuming their required inputs
  
• Fixed recipes with optional inputs not consuming properly
  
• Fixed tooltip issue with selected construction sites
  
• Fixed population not growing properly
