At present, this release includes patch 1.0 - 1.4 , 1.4-.1.5 with Russian and English language packs. I added them in case if something happends to the official site. 1.0 - 1.4 patch upgrades your game to the Enhanced Edition. 1.5 adds the Djinni toolset for the game. 

Installation:

1) Download language pack and patches.
2) Launch 1.0 - 1.4 patch, then choose the necessary language pack. 
3) Patch the game. Wait until the patching ends.
4) Install 1.5 patch.
5) Play the game!

Disclaimer: The patches belong to CD Projekt RED, not to me.

P.S:
All other than Russian and English language packs (Czech, French, German, Hungarian, Italian, Polish and Spanish) are added now too.
