Impulse version was recently updated to version 1.0352.
Google revealed nothing about this one, but version number suggests that it is more recent one than the GOG has. Does anyone know the origins of this patch, the place to download it (if possible) and the changes included?
Also, is there a chance GOG updates to it as well?..

I have no idea what the patch does but if it changes anything to the gameplay and it isn't just just a custom stability patch for the Impulse platform, GOG should get it. They normally then apply new patches to the game and then upload a new installer. I would give it a few days then if GOG haven't mentioned anything on the forums about it, it wouldn't hurt to email them and ask about it.

You can just install it over the GoG version - extract to your installation directory and run the game with one of the suppied executables (Battlecry1035.exe or Battlecry10352.exe).
Be sure to get the fix and copy that over too.
