Latest build shows 1.7.1, while the offline installers are 1.6.3.

Not gonna buy the game here if the offline installers are gonna be out of date. This is an issue with a handful of other games here too, like Volgarr II.

I checked GOGdb and it says Songs of Conquest v1.7.1 was released on October 3rd. But the GOG offline installers are still stuck at v1.6.3 which was released on October 1st. Right now the offline installers are 13 days out of date. Will the game dev update this soon?

Any update on this? The offline installers are still stuck on v1.6.3.

They appear to be updated now. Apparently the Galaxy only builds were beta test builds, but now seem to be available in the offline installers.
