Patch 1.8 for Might & Magic: Heroes VI has been announced; it will be released on Monday at 10:00 CET. Check out the full changelog for the game here (see page 27 for the 1.8 changelog).

NB! Some maps will have fixes that makes pre-1.8 saves incompatible with the new version, meaning that once you download the patch, you need to restart those maps. Only the following maps are affected: "Princess of Varn", "Succession Wars" and "A Tale of Two Guardians".
