Overnight, Apple has pushed a silent update to the Gatekeeper security data for macOS 10.12 Sierra and, presumably, for El Capitan too.
This brings the Gatekeeper Configuration Data to version 109. As usual, Apple provides no information as to what this update brings or protects against, and does not even acknowledge that it has occurred.
At the same time, the Chinese Word List Update has been updated to version 5.15.
Those using my free LockRattler (see Downloads above) should see the Gatekeeper data version incremented accordingly, and I have updated the articles here which maintain this information.
