Ubisoft has just released patch 1.6 for Heroes of Might and Magic V. In addition to a series of fixes, the update includes interesting features, some of which I think already appear in the Tribes of the East expansion:

Kingdom Overview

Extended Number of Turns on Cursor

Wait Button

Sleep Mode for Heroes

Threat Indicator for Enemy Stacks

Autocombat Without Magic

You can download the file from the Ubisoft FTP, or look for a list of mirrors on the official site. According to Jolly Joker at the Round Table, patch 3.1 (for the Tribes expansion) will be released soon as well, but you will have to wait a little more for Hammers of Fate's patch 2.2: "[I] can't imagine 2.2 being released earlier than at least a month after 1.6 and 3.1."
