Ever so often, I receive update notifications for games in my library.
Which could be a nice and useful thing, of course...IF the changelog would mention, what exactly has changed.

But quite often, there isn't even a changelog attached.
And even when there is one available - the latest entry is usually long out-of-date (most recent example from today: more than three years old).

So my question is:
What's the point of having a changelog, if it isn't put to effective use?
Respectively, what is the point of having a changelog, if it isn't updated to the latest status?

I have complained about this to no end, only to hear the same broken record answer, "They only can publish the changelogs that they get". As with game version parity between GOG and other store fronts, they just do not enforce it. It would be nice if users didn't have to do the legwork of GOG employees, having to find and post changelogs on their own accord. However that would be too much for GOG to handle apparently. As with a slew of other long standing issues, this will most likely never change.

It is pretty absurd that in order to see what's changed with a new GOG update you're basically encouraged to visit a certain competitor and click on their "View Update History". But then along with missing achievements / Linux versions / DLC / mods, delayed updates, etc, it's simply the natural outcome of moving game support from the developer's site (where only one patch was needed and worked the same for everyone regardless of where you bought it) to each individual middle-man seller's store (knowing full well in advance that smaller stores that came after the first one would be disproportionately impacted by the walled-garden "convenience" Steam 'invented' (which in reality has ended up just another word for "intentional industry fragmentation").

Hellblade: Senua's Sacrifice was updated a few days ago. It's a graphical overhaul like Metro Exodus, but there was no announcement anywhere as far as I know. I didn't even get a blue pip in my library. For that matter, there's no patch available; you have to download the full game. And the latest entry in the changelog is from 2018. To find out what changed, you have to go digging through the forum -- it's not in the sticky Changelog topic.

I wish whoever is in charge of posting updates wouldn't sabotage the games with their laziness.

The reason it's never done is because developers don't bother with gog.
It's not gog's job to post the changelogs, how would they know what every single game update changelog is? That's the developers job.

Only dedicated hardworking developers do this. Hellblade hasn't posted once on gog, obviously they aren't posting their changelogs here either. I'd say 95%+ of the games here don't have an accurate changelog, and shocker, the ones that are posted for those games aren't posted by the developer but by our community. We have to dig through steam, and chances are they don't even bother to have a parity version number.

For example, many developers dump the game here after it's been out for months elsewhere. Elsewhere the version is 1.1.33, and they put the same version on gog, as 1.0, complicating things even more.

What is, or should be gog's job, is to correct this when curating a game, but they aren't good at their job.
Lazy, understaffed, incompetent, the reason doesn't really matter, the outcome is the same. This is why the hardworking developers that actually spend time here, and monitor/update their forums on a daily basis should be supported, but instead, DRM devs get the most support on gog.
