What probably matters to youSection of the release
What
The screenshot tool's scale parameter now has a real description instead of an empty stub. It explains that a scale of 0.5 returns roughly a quarter as many tokens, and that coordinates you pass back are always in the full-resolution frame regardless of the scale used. A new action set including zoom and the usual mouse actions was added alongside it.
Evidence
Coordinates are ALWAYS in the full-resolution coordinate frame
