Why increased PT-USDG supply cap suddenly?

Just 20 minutes ago, the PT-USDG supply cap on AAVE V4 suddenly increased from 15 million to 30 million, but I haven’t seen any comments from a Risk Steward regarding this action??? Why was the supply cap suddenly increased??? Furthermore, while the supply cap was raised, the borrowing limit wasn’t increased—what’s the point of that? Was this done by Llamarisk, or was a vulnerability exploited?
