Full version. from here
Some parts were quite difficult to translate, as the meaning of certain text passages wasn't entirely clear, but you'll see for yourself. I hope you'll understand =)

Hotkeys CTRL + 1,2,3 in castles

Four new Multiplayer maps:

List of fixes:

Game crashes and stability.

Maps.

Fixed in-game bugs.
- a ghost cannot see the number of creatures on the map if one of the heroes has not developed the "Scouting" ability
- all creatures can now use their special abilities, even when "Subjugated" by an opponent
- the "Tax Collector" ability works correctly, even if peasants are split into several stacks
- fixed a bug where artifacts previously bought at half price could be sold for full value
- "Summon Ship" now works normally under bridges and on beaches
- Remote Control ability fixed
- elementals can become sworn enemies
- a hero equipped with angel wings only needs one mouse click to continue moving.
- if a hero passes through a whirlpool or portal, he (updates himself its Patch now) - meaning... uh... gets experience, maybe?.
- AI now collects artifacts normally.

Gameplay balance changes:
- meteor shower damage reduced on advanced and expert levels
- "subjugation" is not removed from a stack even if it is attacked, however, each hero can only have 1 subjugated stack
- fire traps no longer appear in random places on the map, but in a 5x5 square specified by the player. Within that square, the placement is random.
- Arcane Armor absorbs more damage
- no more than one phantom of each stack can be on the battlefield. Phantoms have as many shots as the original they were copied from
- the "Summon Creatures" spell consumes 75% of movement. Therefore, it cannot be used at the end of a turn
- each "Raise Dead" reduces the stack's HP by 20%
- each "Resurrection" reduces the stack's HP by 10%
- the "Spirit Master" ability allows increasing the spell power level when casting "Holy Word" by +4
- the "Pain Master" ability allows increasing the spell power level when casting "Unholy Word" by +4
- ghosts and wraiths have more HP but less damage
- the "Cavalry Commander" specialization gives a general bonus to damage, rather than to (put back field) possibly, to each cell, which apparently seriously "nerfs" Axel
- the "Iron Maiden" specialization increases spell power by 1 for every 5 levels with each casting of Fireball
- the "rapid slamming shut" specialization gives an initiative bonus to troops of 0.5% per level only at the very beginning of the battle
- the "Animation" specialization gives a spell power bonus of 1 for every 5 levels with each casting of Raise Dead
- construction costs in castles have been rebalanced
- "Poison Lord" specialization now works correctly.
- Eruina: duel mode: army slightly weakened
- Lethos: duel mode: "four-leaf clover" replaced by "tunic of carved flesh".
- Mana cost for casting level 3, 4, and 5 spells has been increased
- the "War Machines" skill now adds HP to those very machines.
- the catapult has infinite ammunition.
- all mages, warlocks, and necromancers start the game with a spell.

Camera and interface settings changes
- spell effects now match the animation
- the camera follows the hero's movements instead of staying in place as before
- knights no longer disappear from the screen if they use Gegenwehr (not even found in the Russian-German dictionary) against obsidian gargoyles
- if a municipality or town hall is built, textures no longer disappear
- in ghost mode, the camera has a corresponding interface (strange)
- battles on bridges now always occur in the correct zone (probably on the bridges themselves rather than nearby)

Interface.
- after defeating an enemy hero, you will see a table with trophies
- some hints (?) in the duel lobby (meaning directly during hero selection, probably) have been corrected
- in the duel interface, hero icons no longer cover their level and army information

- switching between heroes in the tavern works correctly.
- allies can now see the map revealed by a player using an observatory or magic hut.
- several texts have been corrected
