The "Patches 1.41+2.1" thread on the official forum includes a notification from community manager Acheval that the patches will be posted on Tuesday only: "Because of the servers changes, we must restrict patch installation until after they are back online."

Jolly Joker, who has been testing the patches for a while, was kind enough to provide information about some of the changes: "Necro Skeleton raising works in principle like before, however, there's a cap called "Dark Energy". A Necro player gets an amount of Dark Energy each week depending on a) Heroes and their level and b) a few dwellings. If you raise skeletons after a battle you have to pay dark energy for it." He also says that the issue with dwarven heroes on the original maps is now fixed. Read the rest of his post in the other thread about the new patches.
