Unfortunately I have to agree here. I now have a stack of unsolved support tickets with the last one just being an outdated offline installer (so it should not take long to fix it). Right now there does not seem to be much difference if GOG support exists or if it does not exist at all.

Count me in.
Something really wrong with GOG support since december.

Yeah, it's really sad that they don't care about this issue. Shouldn't be hard to fix.
I've a support ticket pending as well. C'mon GOG, please reply to our tickets!

2021-01-09 Changelog Extended Changelog for a detailed overview.

This doesn't replace the changelogs posted here but in my opinion it's a good list to check if there are any updates in the downloads of the games we own but are not currently installed.

Oddly, I can't download the offline installer through Galaxy unless I have the game installed. Go figure.

Why did you do it that way, GOG? *boggle*

AI War 2 (offline installer)
Version 2.714 Frigate Surge And CSGs
(Released January 9th, 2021)

The Praetorian Guard no longer gets any mark level upgrades above the ambient of the AI during tutorials. This makes it so that the PG does not show up in force and decimate new players in Midlander.
Thanks to Matalus and smidlee for reporting.

Fixed a very strange error that we are not sure how it was not erroring for everyone, where we were calling some window management stuff from a background thread for the last month or so. Only cracking it open in the unity editor seemed to make it error. At any rate, it's corrected now, but we're not sure if it actually affected anyone.

New Included Mod: AI Shield Generators by cml

This mod adds a special faction, "AI Shield Generators," to the game. This faction consists of a number of shield generators which must be destroyed before the dire guard posts on the AI Homeworld(s) can be destroyed.
Setup:
Enable one or more "AI Shield Generators" factions.
Set the Faction Color, Number of Shield Generators, and Number to Destroy for each AI Shield Generators faction. The first two options should be self-explanatory, while the last is explained in more detail below. It is recommended that you select a different colour for each faction so that you can distinguish between them in-game.
Gameplay:
During the game, you will discover that a number of Shield Generator structures have been added to the map. These structures will be invulnerable to damage until you capture the planet they are on. Alternatively, there is a hack which will allow you to destroy them outright without capturing the planet.
Each Shield Generator faction represents a network of AI Shield Generators. Destroying a number of generators equal to the Number to Destroy will cause any remaining generators in that network to self destruct.
In games where at least one Shield Generator network is present, an AI Homeworld Shield Generator will be added to each AI Homeworld, but they will self-destruct once all of the non-homeworld shield generators have been destroyed.

Included Mod Updates

AMU
Fixed the CostBasedShipSpawner.canSpend() method instead of using the current spawn target cost always using the minimum cost contained. This lead to the ship spawner being able to go into debt even when it wasn't supposed to.
Created the CostBasedShipSpawner.canAffordAnything() method to allow a check on whether or not anything at all can be afforded.

KM
Fixed a slight debug mishap where until Kaizers Marauders were set to spawn by the true invasion time they would read that they were defeated.
Thanks to Doc_Den for a save that lead to finding this.

More System Defenders mod by CRCGamer updated:
Notable changes are that frigates are generally less power hungry, counts found in fleets, ARS, and GCA have gone up. And I rebalanced the AI Cruise Missile Battery to be a little more threatening.

Buffs To Player Frigates

Frigate energy cost rebalance (buffs):
All of the frigates with energy cost 12.5k now have an energy cost of 9k.
This is almost all frigates.
Defensive assault frigates (station-keepers) are now 6k energy instead of 12.5k.
Watchman Frigates (station-keepers) are now 1k energy instead of 3k.
Raid Frigates are now 6.5k instead of 7.5.
Brawlers and Muggers are now 10k instead of 25k.
Thanks to CRCGamer in particular for the suggestions, and ussdefiant60 as well.

Balance adjustments to make Frigates more usable by always having a bit more of them in ship lines:
For all of these, the changes have been pretty universal.
Ranges of 1-2 are now 2-2.
Ranges of 3-3 are now 4-4. (This is mostly Raid and variants. Are they now too strong?)
Ranges of 2-3 are now 3-3.
Ranges of 2-2 are now 3-3.
Ranges of 1-1 stayed that.
Base Game:
Assault Frigate (no changes to its variants, where were all ranges 1-1; are these now too weak?)
Raid Frigate
Bounty Hunter Frigate
Apparition Frigate
Suppressor Frigate (range of 2-4 became 2; this is crazy powerful in general).
Siege Frigate
Devestator Frigate
Ion Disruptor Frigate
Tritium Sniper Frigate
Ramifier Frigate
Warbird Frigate
Ripper Frigate
Warbird Hydra Frigate
DLC1:
Tesla Torpedo Frigate
Tackle Drone Launcher Frigate

The assault frigate variants that had a range of 1-1 now have a range of 2-2. For the defensive station-keeper ones that were 2-2 for some, and 1-1 for logistical, those are now 3-3 and 2-2, respectively.
Thanks to zeus for suggesting.

Trine 4: The Nightmare Prince

Updated to 1.0.0.8580 (Galaxy & Offline Installer)

Changelog from Steam:

I have the game installed and can't download anything through GOG Galaxy. Galaxy has many problems with this game in general.

1) You can't download the offline installer files
2) The activity feed is not working for the game
3) Some achievements do not unlock (I have beaten the game on "I am death incarnate" but the achievement is still locked)
4) GOG Galaxy keeps desyncing the game so it becomes a "Unknown game" and sometimes every available version and DLC for this game suddenly is listed as a seperate entry.

Nobody at GOG seems to care when it comes to fixing all this stuff which is kinda weird since they love their launcher so much usually.

Oh btw, if you have seen the "Could not write crash dump" thread in the Wolfenstein series subforum: I'm in contact with the Bethesda support since some days and told them all the things I experienced with this issue. They replied to me today that they have forwarded this to their developer team to see if another patch might be needed. When I have any new infos I'll let you know.

Stellar Tactics

Windows offline installer updated to version 0.569

Changelog for 0.568 and 0.569 posted by the devs in the game's forum.

From the GOG Database

2021-01-10 Changelog 2021-01-11 Changelog Extended Changelog for a detailed overview.

(EDITED 2021-01-11 list)

I don't know if it could be the issue, but as you can see here Wolfenstein II: The New Colossus is of "Package" type, I've noticed that games with downloads (offline installers/extras/...) are of "Game" type (or "DLC") as you can see e.g. here, so... wrong type assignment?

"Product changed" is useless for this thread.
We just need "Downloads changed"

Astrox Imperium

From 0.0110 to 0.0111 (Galaxy & Offline Installer)

Changelog from The Astrox Imperium Wiki:

OK, done.

In my intentions I thought I would just copy and paste the daily changelog so as not to take long and maybe not to miss updates made in a "strange" way (I have not searched the list enough but sometimes it is not very clear to me what is actually changed and surely it is not my intention to check every change every day), however it does not cost me so much to remove them (without checking).
