Happily updated the Windows version yesterday! But I have checked off and on for a Linux version all day, and it's still on the older build. Is it just GoG's Q&A slowing down the publishing process?

Yup I'll chime in on this too. I actually saw the update logo for Hollow Knight and blindly installed it. I noticed that the install file had the same version number as the previous file already saved on my computer and found that a little suspicious.

I installed the game anyway and it doesn't seem to have any of the new updates. There are several small clues, but obviously the Linux version available for download is NOT the newest version.

If the powers that be can get on this, fans of the game will appreciate it.

I don't know what is slowing it down, but yep. Still no 1.3.1.5 for Linux; Windows and even Mac got it very early yesterday. I checked all day, and this morning; still no Linux. Team Cherry said it would be up for all players on Humble & GOG "within 24 hours".

As of writing this it has been 30 hours.

Thanks for the answer! I couldn't find this anywhere.

Well, that's a kick in the hype train. Maybe it's held up in Q&A over something, but it's exactly things like this that makes me happy to be a Steam/GoG crossbuyer for indie games. I get updates the instant they're available on Steam, and updates for the DRM-free builds whenever GoG gets around to publishing them.

Seriously, waiting for GoG to play catch-up with the Steam counterpart of a game is frustrating. Sometimes a completely broken build makes it through anyway, so what's the point? And we still can't edit our reviews to reflect those changes?

What do you mean by that? Do you buy your indie games twice - once on steam and once on GOG? Or do you mean you buy them from Steam and then use GOG connect? Neither choice seems reasonable to me. I agree this is an issue that GOG should have solved long ago. Devs should be able to automatically push updates to their games. Whatever layers of packaging GOG decides need to go into each build are not worth the frustration the players experience by having to wait longer than customers of other stores for their updates.
EDIT: Please disregard this point. Apparently I am mis-informed!

Indies are so affordable compared to AAA games, and more often need the support, I don't think it's unreasonable to have extra layers of convenience, especially if it puts more money in my favorite dev's pockets. Once on Steam so I can get fast updates, as well as games GoG doesn't have, and a second time on GoG if the Steam version isn't DRM-free. The occasional sale price slash helps make this easier.

This is why I didn't buy Shovel Knight or Hyper Light Drifter twice. The Steam versions launch without the client, so I have all the DRM-free backups I want.

All of this would be different if GoG would allow developers to push updates themselves. The Galaxy Client getting beta updates isn't enough for me, because I buy games on GoG to get away bloated gaming management clients. Galaxy's not even on Linux, either, and they have no intention of fixing that. Meanwhile, Steam has been on *everything* for years.

tl;dr, I like GoG, but they're annoyingly behind the curve on this growing digital marketplace, which has an impact on my spending habits. Otherwise, I would buy all my favorite indies here, and only here. They're not doing enough to diminish Steam's gross monopoly on PC games.

They can.

Just as an FYI, if no one else has noticed, a new download is up for the Linux version of Hollow Knight.

On a side note, its significantly smaller than the previous installer (1.1 gb vs 1.6). I wonder if that means anything.
