Devices behind a dock or hub now show where they're plugged in

This release is about your dock. If you connect through a dock, a hub, or a
monitor with USB ports, the devices hanging off it now appear nested under what
they're actually plugged into, instead of as a flat list or not at all.

Fixed

• Devices behind a dock or hub are listed, and nested correctly. WhatCable
  now shows everything behind a dock or hub with each device under the hub it
  sits on, so a trackpad behind a hub behind your dock reads as exactly that.
  Before, those devices could appear as a flat list with no hierarchy, or be
  counted but never listed. Thanks to @jesserobbins and @tomjn for the reports.

Under the hood

• Improved diagnostic data. The Contribute Diagnostic Data feature now
  collects more accurate USB, Thunderbolt, and display information, which helps
  us improve cable, port, and display detection across more Macs.
