There are far too many threads here on GOG to keep track of them, that's for sure :P.

Probably a good idea to at least follow that one though. It's the "what did just break?" thread.

I think it might have grown out of a discussion in this thread, actually. Either that or the complaints on the thread announcing the unbundling of games.

The fateful post was post #7200 in this thread.

NOTE! CHANGED Windward, changelog (http://www.an-ovel.com/downloads/chg/chg_1434370838.htm)
NOTE! ADD +++ 2015-10-23.1 (26th October 2015)
NOTE! ADD +++ Completely redesigned how ships are structured and stored in the resources. It’s now possible to create custom ships and package them into a single file that will then be picked up by the game. It’s a big change aimed at making modding ships much easier and will be explained with a video in the near future.
NOTE! ADD +++ Added two new ships, bringing the current number of playable ships to 15. Note that due to other changes below you won’t see new ships for sale until you unlock them.
NOTE! ADD +++ Improved how ship sails are structured. Before every sail was a separate cloth item, but now all of the ship’s sails are under one object. This should improve performance, especially on mobile devices.
NOTE! ADD +++ Added ghost ships (/set halloween = true).
NOTE! ADD +++ Improved the look of all ships (more details are shown with higher graphics settings).
NOTE! ADD +++ Before a ship can be purchased, one must now first find and defeat enough enemies sailing that ship (anywhere from 1 to 10, depending on your luck!). If you’ve already unlocked a ship prior to this update, it will stay unlocked.
NOTE! ADD +++ Turtle Ship and Drekkar are no longer limited to King tier AI.
NOTE! ADD +++ When ships become available to be used for AI is now settable via the config file.
NOTE! ADD +++ Altered stats of ships starting from the Galleon onwards, making their stats balanced in regards to each other. Many ships now have higher stats as a result and there is now a much greater variety to choose from, whether you’re Defensive, Offensive, Support spec’d or a hybrid, you should now have an ideal ship for you.
NOTE! ADD +++ Ships tab in towns will now show all ships for which the player has discovered blueprints, even if the town is too small to build them.
NOTE! ADD +++ Players will now do more or less damage to AI ships based on whether they have encountered them before or not. Fighting a new ship type results in players dealing less damage to it than normal. This penalty is quickly reduced as the player defeats that ship type and is gone completely after 5 kills. Past that it turns into a bonus damage instead (up to 25%). This damage bonus is passive and stacks with everything else. The penalty doesn’t start until regions with talent point requirement of 9 and higher.
NOTE! ADD +++ The Zeppelin can now be unlocked by discovering the blueprint like with other ships, then building it in-town. Doing so costs 1 million gold. The quest route is now half that amount.
NOTE! ADD +++ Server admins can now upload custom pennant and sail textures (these are not symbols!) into Pennants and Sails folders, respectively. Same place the Symbols textures would go. The game will request unknown textures from the server automatically.
NOTE! ADD +++ Added an admin command /upload to upload something to the server. For example:
NOTE! ADD +++ /upload Symbols/Some Texture.png ← will upload My Documents/Windward/Symbols/Some Texture.png to the server if it’s present.
NOTE! ADD +++ /upload Pennants/Awesome Pennant.png ← will upload My Documents/Windward/Pennants/Awesome Pennant.png to the server.
NOTE! ADD +++ /upload Ships/New Awesome Ship.bytes ← will upload My Documents/Windward/Ships/New Awesome Ship.bytes to the server.
NOTE! ADD +++ Note that this command makes /uploadSymbol obsolete.
NOTE! ADD +++ Exported ships can now be a part of mods by simply including them in the mod’s Ships folder and referencing them in the mod’s Config file. Using existing ship names will effectively overwrite the built-in ones, so if someone wants to create better models -- they now can.
NOTE! ADD +++ /set command used to set server options can now load files containing a more detailed hierarchy just like you see in the Config.txt and world.config files. Usage: /set . The “path” is relative to the My Documents/Windward folder, so if you are trying to set symbols that will drop in the game as loot, create a file with contents like this: http://pastebin.com/Z71iDQL7, modify it, save it as My Documents/Windward/symbols.txt, then use the /set symbols.txt command to send it over to the server. All this command will do is parse the file like it was a part of the config file and update the appropriate value on the server, automatically merging it with all existing data. You can use a different name than “symbols.txt” of course, just make sure it matches the /set command.
NOTE! ADD +++ Server admins can now upload new custom ships to their server using the /upload command. All players will automatically download these new ships and they will appear in towns and will be used by NPCs as if they were built-in. No mods required this way, assuming the custom ships don’t use any custom code. Tutorial video: https://www.youtube.com/watch?v=UE40pLt1VLw
NOTE! ADD +++ /get and /set commands now support hierarchical paths. For example:
NOTE! ADD +++ /get Factions/Fac0/Multipliers
NOTE! ADD +++ /set Factions/Fac0/Multipliers/Damage = 2
NOTE! ADD +++ Completing a trade or a quest will now result in the town’s production/demand increasing or another quest getting added.
NOTE! ADD +++ Trades that fulfil higher demands will now grant items to the player completing the trade. The greater the demand, the better the reward.
NOTE! ADD +++ When towns gain levels their production and demands are no longer reset.
NOTE! ADD +++ Quests now have random bonus objectives (up to 3), such as avoiding enemies or completing a trade along the way. Finishing a quest with a completed bonus objective gives an item as a reward. The more bonus objectives were completed, the better the reward.
NOTE! ADD +++ World generation no longer places pirates everywhere. Most of the world will now be empty, up to players to colonize. Those that prefer action can still run instances or visit the regions that are still pirate-controlled.
NOTE! ADD +++ It’s now possible to generate flag type items that change the texture used by the pennant on top of the ship’s mast(s), although I’ll leave this as admin rewards / modder items and will cover this in a future tutorial.
NOTE! ADD +++ Added a slider to world creation that lets you adjust the amount of pirate-controlled regions when generating a new world. 0% = no pirates, empty world, yours to colonize. 100% = pirate towns in every region, yours to capture.
NOTE! ADD +++ You can now specify pennant textures used by factions in the config file the same way you can specify symbols (pennant = “Texture Name”). Place the pennant texture in My Documents/Windward/Pennants. It must be a PNG, ideal dimensions of 128x32. The texture will be used as a mask by default where Red = grayscale, Green = mask showing which part is colored by primary and which by secondary pennant color. Blue = unused. Alpha = defines the shape of the pennant. If you don’t want it to be masked and want to use it as-is, make the texture’s name end with “RGB”. Example pennants can be found here: http://www.tasharen.com/windward/pennants.zip (but note that the game can only load PNGs).
NOTE! ADD +++ Added /createPennant , matching the /createSymbol command. To upload custom pennants, use the /upload command. The full process is as follows:
NOTE! ADD +++ Create the pennant texture (128x32 dimensions) and save it under My Documents/Windward/Pennants/.png
NOTE! ADD +++ If playing online or if you want to update an existing texture while in-game, use /upload Pennants/.png
NOTE! ADD +++ Create the equippable pennant item using /createPennant
NOTE! ADD +++ It’s now possible to have colored symbol textures. To have a colored symbol, simply have the texture name end with “RGB”: https://www.dropbox.com/s/caezq5p620owzkp/Smiley.jpg?dl=0
NOTE! ADD +++ Removed the timer on paints and dyes that would dry them and make them “baked in”. This makes it possible to always unequip customization items, restoring faction colors.
NOTE! ADD +++ Note that restoring faction colors won’t work on ships created prior to this update. I chose to do it this way so that players won’t suddenly lose their chosen colors.
NOTE! ADD +++ Made pennants show their texture in inventory much like symbols.
NOTE! ADD +++ Created a ship modding project used by the ship modding tutorial video. http://www.tasharen.com/windward/mod.zip ← requires Unity 4.6.9 (http://beta.unity3d.com/download/7083239589/UnitySetup-4.6.9.exe). Won’t work in Unity 5. Check the ReadMe file for a brief explanation of the steps necessary in order to create and add new ships to Windward.
NOTE! ADD +++ Put up a new PvE server (Tasharen East Coast 1) with a world generated as 50% pirates, giving players the option to either fight or colonize, depending on their preference.

[The Mac installer is still there, but apparently Mac support is officially gone]

Mac file still available here. Thx, also, for the answer re: gog version number bugs a few days ago.

Apparently not a bug:
"Zachtronics has stopped supporting the Gold Award-winning puzzler SpaceChem on iOS and Mac".

The Mac version was also removed from Steam.

Are update notifications broken again?!
I don't get any notifications since days, e.g. for Rebel Galaxy. I never got an update notification for Witcher 3.
How many decades does GOG need to fix this? ;-)

If you'd ask me, I think that unfortunately they don't really care anymore that much since Galaxy and its auto-update possibility.

I'm afraid that you're right. I don't like Galaxy because of this :-(
