What's changing
Note
A terminal disclaimer is on file and its reference is not resolved. No cap is applied and none is guessed
Open question
A terminal disclaimer is on file (approved) and its reference document is not resolved. A disclaimer would cap the term earlier than Oct 7, 2025. We will not guess the cap.
