Release 1.56.1
Your Mac doesn't sleep in the middle of your agents' work. Before, if you left agents working and went for a coffee, the Mac went to sleep after a few minutes and the work stopped halfway. Now, while any agent is in the middle of a task, the Mac doesn't go to sleep from inactivity. As soon as the last one finishes or starts waiting for your answer, the Mac goes back to its normal energy settings.
A Mac awake badge in the footer shows when this is in effect. The display still turns off as usual, and closing the laptop lid still puts the Mac to sleep.
It comes on by default. In Settings › Agents you can turn it off, or ask for the display to stay on too while the agents work.
