The credit purchase amount input has been redesigned from a filtered numeric text field to a validated text field with inline error feedback. Amounts must be entered as 20 or 20.50; a separate "Confirm amount" dialog now requires typing yes to confirm a billing action.
Evidence
Amount validator returning "Enter an amount like 20 or 20.50" (search for "Enter an amount like 20 or 20.50") and new confirmation dialog (search for "Confirm amount")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
