The main focus of this update is to respond to player feedback by creating a better balance in terms of difficulty and to serve up more challenge. We have tried to leave no stone unturned in this exercise, so the patch includes many granular level changes. You can see all of them laid out in detail here but below is a summary:

Increased cost of buildings, in particular higher tier buildings
Food costs for higher tier buildings increased, and more food cost for some Market income buildings added
Adjusted some bonuses from Market income buildings to tone down how much income some late game provinces could get
Estates now cost -100 gold for each one not held by your King
All tax levels now give public order penalties, halved public order hit from occupying settlements from -10 to -5
Changed Victory Conditions for many factions to improve variety of play styles and fix some instances of too-early victories
Reduced some bonuses from technologies so they are less overpowered, in particular the +15 melee skill technologies are now +6 bonuses as the previous value was a huge increase for many unit types
Reduced upkeep and recruitment cost reduction bonuses from traits from -50% to -25%
Adjusted AI bonuses from difficulty levels
Change to Supplies so armies start with a lower value and some bonuses from buildings reduced and Supplies lost in enemy territory increased so Supplies has more of an impact
Changed when different negative faction food penalties are applied so harsher penalties apply earlier, and changed the effects to have more impact
Made changes to War Fervour so only changes to score in last turn shown, and impact of War Fervour technology changed as well
Some unit balance adjustments made, in particular to Berserkers
Made changes to increased the length of melee combat so battle line will be closer to the length we want to see
Changed spotting values so units in trees can hide better
The beta also includes a number of quality of life improvements to the UI, some Art improvements and bug fixes.
