Patch 1.5.7
Massive errorfixing patch. Congratulations, you're now playing the total conversion with the smallest possible error.log on startup! (Only 15 lines, discounting any errors from incompatible save games you might have!)
Added cultural delicacies: Chouta, Shin Strawberries, Horneater Stew, Taifruit Salad, Bladefish, and Makabaki Pancakes.
Event: Your master chef (court position) makes you a foreign delicacy.
Feast event: A participating Unkalaki pulls out the Horneater White and challenges you to drink it.
Various localization tweaks

Note: As Paradox Plaza is currently down, I'm unable to upload the patch there, so this one's Steam-only for now.

Patch 1.5.6
Integrated Agamidae's Court Customizer mod
Added stricter caps and new "Max" buttons to Feruchemy; It's still possible for the cap indicators to be incorrect when near the PDX-hardcoded limits, but you can click twice to get the real cap.
Slightly more lenient Stupid Difficulty to avoid negative modifier overflow
If you have a Poet in your party, they will now comment on your decision to kill the abandoned loner during the delve.
Told the Fishing minigame to shut up when not shown. (This was the cause of the annoying seaspray noise at the start of the game)
Wrote a tool for supporting dynamic city sprawl. I don't personally have much use for it in WoK, but it's been shared with other mods who do have use for it.

Patch 1.5.5
Reworked Mercy's Victory: Added the "Grant Mercy's Reprieve" interaction to Forgiving characters to help achieve Mercy's Victory.
You can now achieve Cultivation's Victory as an adult if you have 2 children who satisfy the previous requirement.
Traded favors with Jaime-san from the LotR: Realms team and earned a visually reworked Aimia!
New loading screen art, by Bren Saxton
The Tower of Urithiru holding tiers 4 and 5 each provide +1 building slots (Each effect can only fire once per game)
Buffed the base Feruchemist trait, but capped Feruchemy tapping at 2x the storage cap or at the rest of your stored power, whichever is smaller.
Attempted fix to the issue where AI characters who were being targeted by the player's arranged courtships could get married anyway.
There are now recipient events for the squireship interaction to inform you of what happened.
Fixed Adonalsium not unlocking the console

Patch 1.5.4
Fixed typos which were preventing Nightblood and The Way of Crusader Kings artifacts from being created
Removed vanilla availability blocker which was preventing players from being able to go on a Nightwatcher pilgrimage.
Level 5 Transportation-surgebinders can now teleport to any Dawncity from anywhere. However, if they are not currently in a Dawncity, then they have to pay 50% of the normal investiture cost rather than it being free.
Fixed vanilla bugs with the Feast invitation effect - you should now invite your family members, rather than the family members of the feast itself. (???)
Added some RAFO/PAFO worldbuilding, equal parts from preview material and my own twisted fan theories.
Singer heritage now informs the player that it is required for Singers in order to use non-Slaveform/Dullform forms.
Fixed list builder trigger localization (It used to be broken, I fixed it manually, and now PDX did their own fix by moving to a new system which broke my fixes)

1.5.3
Radiants can no longer wear regular Shardplate, but can now properly benefit from Nightblood.
Greatly reduced the size of the errorlog, and reenabled a few vanilla flavor events in the process.
Added better "Playable difficulty" information breakdowns on the character selection screen (Not the bookmark screen). This helps clarify which regions are well-supported for modded flavor and which regions aren't quite up to that level. It also mentions any unique mechanics they have to deal with, such as consensual marriage or wonky electives.
Localization fixes for the vanilla tooltip for unplayable characters (Since 1.5 it had a broken Perspective set)
Greatly reduced the chances of Elhokar being decapitated in a random court event in the first month.
Slightly toned down the metallicity gene for the Iriali ethnicity.

1.5.2
Integrated changes from CK3 patch 1.5.1.1
Enabled the Make Fabrial decision. It's not super integrated, but it reuses old code so the current implementation was easy to make.
Someone with a Witch secret converting to a faith with Witch doctrine set to Accepted or Promoted will not lose their secret and gain the Witch trait in its stead.
The Master Chef should no longer automatically fire themselves.
The Eastern Shattered Plains' duchy building and duchy capital are now both in sector Jes. (Base game change detached them in 1.5 so that the building is always placed in the first county in the county list rather than the capital)
The Everstorm title is now correctly destroyed when the Harbinger dies, requiring a new storm to be summoned to reform it.
Adjusted the character sort-by-skill buttons to be aligned with the skills of the listed characters
Miscellaneous error fixing

Patch Notes, 1.5.1: Feruchemy and Knobweed
Feruchemy system added
Harmony's victory now grants half your house the Mistborn trait, while the other half gets the Feruchemist trait.
Not all the feruchemical metals are usable by/known to the player character.
The meta-reason for this is because those metals either don't make sense as having geopolitical effects, or because the obvious effect (Steel should store Speed) would easily crash the game (Negative movement speed modifiers crash the game) and there's nothing I can do about that.
Iron: Weight - Stores weight. This should only have a visual effect, no real gameplay impact.
Tin: Senses - Stores Secret Discovery chance
Pewter: Strength - Stores Prowess
Copper: Memories - Stores Learning and lifestyle XP rate
Bronze: Wakefulness - Stores Stress gain and lifestyle XP rate
Gold: Health - Stores Health
Electrum: Determination - Stores AI_Boldness, AKA Dread Resistance
Nicrosil: Investiture - Stores monthly investiture
Aluminum: Identity - Stores prestige, grandeur, and scheme secrecy
Duralumin: Connection - Stores opinion of same faith and same culture characters.

Flavor
Added event chain "Knobweed" about finding some particularly supple knobweed.
Added metallic skin gene, primarily prevalent among the Iriali, but also present in the Singer population.
Added more nuanced terrain to Alm and some of Yezier
Added placeholder terrain to Shinovar (Playing here is still not fully supported, however)

Fixes
Herdaz is once again Feudal
Fixed issue where all impassable terrain, including mountains, counted as sea tiles for the purposes of designating coastal provinces. This was causing trade ports to be built in mountains.

Miscellaneous map bug fixes

Updated for CK3 v1.5.1
Added dynamic custom sidebar for mod compatibility. To demonstrate to modders how easy it is to add new windows, I've added two new sidebar-accessible minigames.

Wokle
It's like wordle. https://www.nytimes.com/games/wordle/
Uses a Coppermind-based word database and uses pattern recognition to provide word suggestions if you're 1 letter away from a valid word.
On hard difficulty or higher, you cannot change letters that you've guessed correctly.
There are minor rewards and penalties based on your performance. It's not easy to make a net profit.
"Requires" literacy.

Tetris
It's Tetris.

Information Networking
Added Information Networking councillor task for cultures with the new Information Trading tradition.
Depending on your councillor's skills and opinions, they may acquire secrets for free, facilitate information trades, or leak your secrets to others.
The more people who are connected to the network, the more likely you are to find a trading partner with a secret of interest to you.

Find Courtship Match
You can now arrange courtships directly from your candidate by using the Find Courtship Match interaction, which is to Find Spouse what Arrange Courtship is to Arrange Marriage.

Tweaks
Adjusted court type availability overall.
Added prototype 3D GFX for Shardblades to dungeon delves.
Refactored investiture script value breakdown to the new Royal Court system.
Fishermen tradition now boosts the Legendary Fisherman trait.

Bugfixes
Shardic artifacts should no longer get upgraded in random events.
Heraldic Faiths no longer consider every faith to be righteous.
Heralds should no longer be super eager to duel people.
Marati duchy capitals should once again have duchy building slots.
Pregnant singers should now enter mateform.
Tons of stability, localization and database error fixes.
Minor mapping fixes.

1.4.2
Added the Master Chef court position. In a future update it will enable foodies who share your favorite food to make a pilgrimage to your realm capital in order to savor the food.
Added Lumicide tradition, rewarding you for executing those darn Radiants.
Added Scalar Health tradition, granting some bonuses to the Scaly trait.

Tweaks:
Bavland now starts vassalized, but exempt from every feudal contract.
New Gerontarch flavor for Eldrics (Still using "Eldric" for most things as I think it sounds more fun)

Bugfixes:
Artifacts now properly affect artifact progression speed of Bondsmiths and Dustbringers.
Fixed spren houses not being assigned correctly.
Fixed Artifabrian soulcaster discount.
Fixed the Revive Shardblade decision.
Exempted characters with scripted visuals from starting with one of the ten randomly distributed shardblades on game start.
Removed vestigal artifact map modes.
Fixed poop events.
Fixed the Dungeon Delve crew selector decision GUI.
Many localization fixes and generic error fixes.

Patch 1.4.1: Patch notes:
- Fixed shartplate event not firing during combat
- Removed the vestigal artifact and shardbearer map mode buttons, as it would not work with the new system.
