Can't confirm.
Everything is perfectly fine for me.

At least for vanila 'Special Edtion'. Don't own 'Anniversary upgrade'.

The memory leak was reported right here in the GOG forums.I haven't verified the memory leak myself yet, but with the large amount of users reporting it I highly doubt that it's not an issue of the game itself.

I never had memory leak playing the Anniversary version. But maybe I have not played long enough

The memory leak should only affect you after 2-3 hours of continuous play, maybe more depending on your VRAM, do you play for that long each session?

Last time I played - I have pretty long sessions. Sometime for 5+ hours.
Zero problems.

My ram - 16 gb, vram - 8gb.

I also have 16 gb ram and 8gb vram and it still happens after 3 hours that the anniversays version last version freezes due to memory leak.
There is something wrong with Skyrim on gog.

Maybe Anniversary content is our culprit ?

I don't own it. Can't validate.

Albedo: Eyes from Outer Space is currently on the list for "missing updates since May 2015". I compared the Steamdb and the GOGdb pages of the game and I actually discovered that the game on Steam was no longer patched after September 2015 and it was released on GOG only in 2018. I highly doubt they released an earlier version on purpose, so I'd be inclined to take it off the list unless we can demonstrate the GOG version is actually inferior.

Amnesia: The Dark Descent has received the Simplified Chinese translation on GOG.

Escape Goat has received the French language on GOG, but German, Spanish and Italian are still missing.

I don't know anything about the game's state, but I do know that it was released on GOG on April 10, 2015, not in 2018. I myself bought it in December 2015.

My mistake, I had only checked the Changelog section on GOGDb. Yes, the Builds section says that the game was first uploaded in April 2015, and then in 2018 it was updated from "no version" to "1.00".

However, I looked better into this. The changelog on GOGDb claims that this 2018 update was merely an update on the installer structure and nothing was changed on the game itself. But I then checked all the updates that the game received on Steam after April 2015, and all entries on Steamdb read "Manifest ID changed", no other game file was ever changed. So it appears game was not missing updates on GOG all along.

Dungeons 3 the soundtrack is available, not as an individual DLC but as a bonus for those who buy the "Complete Collection" version of the game. Of course, it is technically an issue for a GOG customer who wanted to buy only the OST and ignore all the other DLCs, but it's certainly not the same of just "Missing Sountrack".

But I'm wondering, on a theoretical level, if a GOG customer decided to first buy the Standard edition of the game, then buy each DLC individually, and finally to buy the soundtrack, how much would they pay? Would they have to buy the "Complete Collection" at full price or would GOG automatically generate a price that is in-line with Steam? If I'm not wrong GOG does keep track and make discounts when someone buys a bundle and some of the products are already owned.

Highway Blossoms: The free 18+ content DLC is available on itch.io and compatible with the GOG version. Granted, would have been better if GOG itself provided the DLC or at least a link, but the link to the DLC on itch.io should be put to the spreadsheet, so that people who are interested know where to look instead of assuming that they just can't get it all.

The Linux version of Dropsy has been updated to patch 1.5.

For Shenmue 3 can anyone add a note that I created a mod that restores the missing items for the gog version? It also enables some kickstarter items that are not available even in the steam/epic versions. Although it would still be best to report this to the new publisher ININ Games and maybe they can fix this instead of using this mod:
Here is the link
https://www.gog.com/forum/shenmue_iii/mod_missing_bonus_items_for_gog_version

Surely useful, as the gamers will be able to get many of the missing items "back".

Nonetheless, i am not sure the publisher may care and the dev not at all because this "issue" was fully intended it seems.

It may not hurt to inform them, but in most cases they have been "informed" already and they simply may not sufficiently care.

Soldiers: Heroes of World War II got an update on Steam that modernized the game with more modern APIs, proper 4K support and achievements. Best Way employee said that they plan to port it to GOG build, but it will take them a lot of time since game's multiplayer structure is now based on Steamworks networking.

Here are some links about that:

https://steamcommunity.com/app/11480/discussions/0/601895662819273987/#c601895662819286136

Why even base the update around Steamworks if it complicates the process of porting the patch to other platforms? I highly doubt many people are still playing the game online these days. "Soldiers: Heroes of World War II" is not only available on Steam; it's also sold in multiple other stores. Dumb move by them.

Edit: there were 77 people playing the game on steam in 24 hours. Highly doubt most are playing MP.

I see Skyrim mentioned

Now I'm tempted to... uhm, try it for a couple hours. But I'm not currently in the mood for it, that would be dedicated more to F.E.A.R.
