- New channels require both peers to support the on-chain full payment hash feature; nodes no longer open Legacy channels.
- Existing Legacy channels retain their original settlement layout. After the database migration ships, operators should close existing Legacy channels when practical.
- This RC requires a new database. Upgrading an existing database is not supported until a subsequent release provides the migration.
- Existing databases upgrade in place via a migration that adds the `commitment_contract_features` field (defaulting to Legacy) to channel actor state, channel open records, and watchtower channel data.
- Watchtower `create_watch_channel` now accepts `commitment_contract_features` as `"0x0"` (Legacy) or `"0x1"` (full payment hash).
