If your entity has a wacky state that doesn't fit the active_state option, you can now set guess_mode to true—enabling advanced AI† to guess whether the timer is active or idle!‡
That's all! There's not much else in this release, save for modificationss to the debug pane.
† Sorry; it's simply a few if statements
‡ As long as your entity does not rely on using the last-changed-time when computing time remaining.
