thinking of buying it here instead on steam, do the devs update here ?

Yes, the version here is 1.05, same as on Steam.

Seeing as Steam patch was announced yesterday, there isn't much delay either.

Yes.

Waiting on update 1.10.4. Please bring the update to GoG.

Current version is 1.10.22
It seems like the most up to date version. However, i am unable to find accurate Patch Notes... no matter the platform.

Found patch notes on Steam for 1.10.2 and 1.10.1. Unsure what 1.10.22 is for but probably just a small fix.

-Protag gender graphics in cutscenes fixed
-Steam saves now generate a backup in the backup folder (appdata/roaming/nephilim)
-Many RU localization fixes

-Corrected an issue where memory Trait Tomes from 2 or more cycles ago would not be carried over
-Improved the stats of Memory Dragon Riders for early game
-Increased the STR of Aggarak the Returned
-Increased the SKL of Calden Blackwall
-English/Chinese Voice sfx languages can now be toggled in the options menu
-You can now choose the form and name of your main character after starting a NG+ cycle
-Reduced the passive regeneration for Zanatus claws
-Necromancer and Dark Mage will display a gray promote arrow instead of green one
-Fixed a crash associated with a squad with an aura effect being disbanded
-Further translation fixes
-Mid-chapter summons no longer count toward the move speed or type of their Squad
-Fixed up some enemy scrambles to avoid janky gameplay situations like walled-off melee units

Thanks for updating Devs! Love the game!
