The new patch for Heroes of Might and Magic V is out! The easiest way to download it is by using the game's auto-updater, which came with patch 1.1. If you don't have patch 1.1 installed, or if you would rather perform a standard download, look for the appropriate link here (thanks evilp). You need to apply patch 1.1 before you can install 1.2.

You can view the patch readme while you download. Enjoy!
