Changelog for update patch 1.25 (GOG-9) (added 07.10.2015):

- The game now works reasonably well on Linux machines using Wine.
- Fixed various graphical glitches that were happening in various places due to recent Nvidia drivers breaking things
- No longer possible for traitor to get into K15’s office and break the game.
- Fix made to prevent extremely rare chance of Zenlil being destroyed by Kiril's forces at the wrong time.
- Additional fix made to prevent R25 from blocking the cockpit entrance before the mercenary fight.
- Zenlil Minigame: tweaked difficulty and removed iDGi-1 static FX
- Shortened abandon distance for the “do you want to talk to the queen?” convo
- Added text with link on main menu for latest news - for The Tower campaign
- More definitively prevented players from entering K15's cabin during the traitor fight.
- Fix for players getting stuck in the cockpit door if trying to follow Pawn 51 into the cockpit
- Fix made for extreme iDGi-1 signal issue that sometimes arose during the traitor fight - should not happen anymore, but if it does, using the utility energy stations will reset the signal back to normal.

Wait! Does this mean, a patch launched on Oct 7. 2015 (probably on steam) took more than 3 months to get released on gog as well?

Have the developers mentioned anything about continuing updating this? I had actually forgotten about this game, remembering reading about some issues so I waited. If this is the last patch, I'll give it a go.
