Changelog for Patch 1.800 (added 02 May 2017):

New Features
- Added new Build a Water Fortress ability. This enables embarked Builder Units to create Fortresses on water and claim water structures more easily.
- Added new Oyster Reef structure. Oyster Reef generate gold and population within your domain.

Tactical Combat
- Fixed 2 issues where units could sometimes shoot through walls and other obstacles without a line of sight penalty. So your dudes and dudettes are safe behind their walls now.
- Fixed an issue where entering combat would wipe extra move points gained from Death March. Allowing you to use Victory Rush to the fullest.
- Mind controlled/ghouled units now always have 0 move points on the world map after battle. This is intended as nerf strategies based on unit acquisition in combat.
- Mind controlled units can no longer retreat from battle. No more cheap summon stealing, sorry.
- Chaos Rift, Great Immolation and Great Stoning now warn the AI that it needs to abandon siege defense during tactical combat. Charge!!!

Balance
- If a summoned unit evolves, then the summoning spell will be cancelled, and the unit will become a normal unit with a higher mana upkeep. The mana cost is based on the typical cost to summon a unit of the unit's new tier.
- Fixed a bug in the random map generator when generating a map with teams enabled. Teams would always be generated counter-clockwise around the map, making it possible to predict the location of other teams.

Stability
- Fixed a crash when clicking the 'center' button in the 'structure captured' popup after the structure was razed.
- Fixed a crash that would sometimes occur when releasing a city or a dwelling as a vassal.
- Fixed a bug where items being couriered would remain stuck in the hero inventory when an AI hero joins by surrendering.
- Fixed a bug where AI attacked vassal city of friendly player.
- Fixed a bug where unit buffs/debuffs from global spells would sometimes vanish without any reason
- Human Crusader now has the right impact sound.

Multiplayer and PBEM
- Fixed PBEM exploits that allowed a bodged turn to be replayed through save game manipulation.
- Fixed hang in PBEM when one human player remained. Now you can end the remaining AIs rightly.
- Fixed PBEM notifaction issue for other players turn.
- Fixed PBEM issue where player was not properly notified of defeat. This prevents a dead state that has you staring at clouds.
- Fixed PBEM issue when swapping slots in setup. So the host can now safely take slot 2.
- Fixed PBEM issue when PBEM settings where changed before the session was launched. This could prevent a game from being launched, etc.

Modding and Tools
- Fixed a crash when starting a map for which the first map layer was removed in the Level Editor.
- Added mod support for charging mana to build structures and roads on the world map

Graphics and Glitches
- Fixed popups being removed when they shouldn't be. Should help when reading damage popups for spells in combat.
- Changed the ‘Reaper Scythe’ AoW Item Visualization link from a spear to the ‘Necro_Scythe’ model.
- Fixed the Imperial Hand Cannon visualization in Tactical combat.
- Assassin's Stiletto of Silent Murder now has correct weapon displayed.

Text and Localization
- Removed the obsolete 'Vanquish Evil Player' and 'Vanquish Good Player' entries in the Tome of Wonders under alignment modifiers.
- Linked text to fix empty table entries in the ToW under relation modifiers.
- Fixed an incomplete description for the goblin military level 5 race governance skill. It now also states that the relevant unit types get +5 hitpoint.
- Fixed an issue where terrain penalties would still be listed, even through they were disabled by the Bolster spell.

Changelog for patch 1.800 PBEMPATCH / (Windows) (added 11 May 2017):

- Fix for mod incompatibility in the Play by Email multiplayer mode, across game version.

The editor crash patch that was released on Steam (October 2017), never got released here on GOG.

I doubt it ever will. The devs just bypassed the question when asked it about on Steam.

Of course it will be released on GOG. It always takes longer for GOG to get to it

...and 4 months (and counting) is an acceptable time lapse?

Seems the devs couldn't care less about 'supporting' the game here?

Changelog for Patch 1.801 (added 29 March 2018):

Tactical Combat
- Fixed an issue with the Oyster Reef Tactical Map where units were not positioned correctly on their hex due to them being placed too high relative to the water plane.

Balance
- Fixed necromantic circles spawning too close to other spawners, causing roaming unit hotspots.

Stability
- Fixed a rare crash that crashed the game when selling items.
- Fixed a crash that occured when opening a diplomatic proposal which included a structure - e.g. a fortress - that has been razed. The offer is now automatically declined and the razed structure is removed from the proposal.
- Fixed a rare crash in campaign when finishing a map with an active quest which had concealed units.
- Oyster reefs no longer appear in lava lakes in the underground.

Exploits
- When selecting 'Give me a different hero' on a 'Hero Join' event it was possible to kill the declined hero to gain XP and Items. This has been fixed by despawning the hero when requesting a new hero.

UI
- Added support for cursor scaling on all resolutions. Should help people see the cursor when playing on high resolutions.

Modding
- Added a workaround to allow people with high end PCs to run heavy mods.
Especially mods that increase the number of figures - characters - on screen, such as the 'Regiments' mods.
- Create a text file called 'Game.cfg' in the user 'Config/' folder of the game's user directory. E.g. '/Documents/My Games/AoW3/Config/Game.cfg' on Windows.
- Using a text editor - e.g. notepad - add a line saying 'SHADER_SIZE=2'. This doubles the render call limit.
- Please note that this is a workaround and not an officially supported feature. I.e. the game could become unstable and the workaround might still not resolve issues with many figures on screen.

Changelog for patch 1.801 fix (added 30 April 2018):

- Resolved an issue where the launcher would crash when downloading a lot of mods at the same time.

(copied from elsewhere but comes pre-installed)
Age of Wonder III, Version 1.802. Oct 1, 2018

Updated the game to reflect the requirements of the General Data Protection Regulation (GDPR) - a legal act created to enhance your privacy rights; we are working hard to continue to earn your trust, and that’s why we want to keep up to date with best practices.

Stability
Fixed a rare cash caused by quests modifying cities that have been razed during the campaign.
Fixed an issue where removing a mod that allowed more layers than the base game would causes crashes in random map setup.
Fixed an issue where removing a mod that added a new race to the game would cause crashes in leader customization.

UPDATE:
Pushed out a minor patch that changes which documents are shown when logging in, making these documents Triumph account specific. This will require people to accept the privacy policy again. Sorry for the inconvenience.

UPDATE: Just made the version in 'open_beta' public, as it seems to have solved the dead-state issues reported with the v1.802 build.
