I don't want to install or even use something like Galaxy to install development updates. Why are devel updates for Neverwinter Nights: Enhanced Edition only available via Galaxy? Does GOG as a company has any say in the matter at all or is it out of their hands? Either way is a very poor practice, might as well fully switch to the Steam model at this point.

Offline installer seems to be there for me when I look.

Of course dear, 89.8193.37-14+DoIWD is indeed there. But where is the offline installer for 89.8193.37-15?

I see. Your first post deceived me. Sometimes it takes a week or so for updates to get to the offline installers. Sometimes they are forgotten entirely and you need to open a support ticket to remind them.

89.8193.37-15+DoIWD is now available... Why does it say "+DoIWD" though? It makes me think it includes that DLC even though it shouldn't... right?

The most recent edition that I show is 89.8193.37-14+DoIWD

I saw an alert on the page that there is an update, so it may be that there is a new build coming.

I see version 89.8193.37-15+DoIWD for Linux and Mac is available as offline game installers.

For Windows it's still on 89.8193.37-14+DoIWD.

It's a bit confusing to me because adding the "+DoIWD" doesn't really explain much. Beamdog changelog for 89.8193.37-15 says "Added Doom of Icewind Dale to the Premium menu.", so is GOG's 89.8193.37-14+DoIWD basically 89.8193.37-15?

But then again, GOGDB, while not an official source but still very reliable with these things I think, shows a 89.8193.37-15 build for Windows dated 2025-02-24 (I have to post the link like this because GOG won't let me post any more links apparently...)

and it only adds to my confusion.

If you do it like this, it's less work for you and for everybody: gogdb.org/product/1097893768/build/58398883718404306
