All eight candidates are exact matches on Sourcify and verified on Blockscout. FilFox verification was attempted for every candidate and returned an unknown verification error.

Action Required For Integrators

• Stop calling removed piece-metadata getters and index PieceAdded events where metadata is required.
• Account for the new operation fees and lifecycle-reserve target; existing data sets may need additional FilecoinPay funds on their next rate-touching operation.
• Support programmable data-set authorizers and the expanded authorization payloads where used.
