Hotkeys for the two 'Ok' buttons in the swap manager have been changed from Esc and Enter to Enter and Shift+Enter.
[+] automatic bug fixing improved:
-fix algorithm enhanced;
-synchronization of fixes with opponents in multiplayer improved;
-added a fix for situations where a hero is controlled by two players (including AI);
-added a fix for situations where a hero already hired by someone is available for hire in the tavern.
[+] A patch has been integrated that allows game music to play in 44KHz Stereo instead of the original 22KHz Mono + a corresponding option has been added to HiRez.ini (enabled by default)
[+] "Clip Cursor = 1" mode behavior changed:
the cursor can now be moved outside the heroes window while holding the Ctrl key;
the cursor no longer dives back into the window after being outside, as it did before
[+] Checking an opponent via [F2] now also works when the opponent is in battle or the swap window.

Calling the Thieves' Guild via [G] and through the quick menu now also works while waiting for a turn in multiplayer.

Keyboard handling has been changed, which may resolve issues with HD mod hotkeys not working (for those who experienced such problems)

[-] another original "not me" bug in the adventure window info panel has been fixed.
[-] In multiplayer, the [L] - Load Game hotkey was available in the battle window (it is no longer);
[-] The "Extended Combat Options Dialog" option, which allowed disabling additional buttons in the combat options window, has been removed from HiRez.ini.
[-] The total uncompressed size of the mod has been reduced by 3.2 MB by removing graphics files from the Russian SoD pack by Buki. The removed files will be included in another pack - "Russian Mega Pack", which will be available for separate download.

[+] When pressing [F2] in multiplayer, an opponent (if they also have version HD 2.80 and the game bug fix option enabled) is checked for multiple running instances of heroes (SoD, WoG, TE, WT, .. it doesn't matter) and for a running map editor. If the opponent has multiple instances of heroes running, you will see in response to [F2]: MULTI-INSTANCE DETECTED! If the map editor is running, you will see: MAP EDITOR DETECTED!
