Sui Testnet v1.80.1 Expands Protocol 137 Features For Node Operators

Mysten Labs has released Sui testnet v1.80.1 using protocol version 137. The build includes updates across protocol logic, GraphQL, JSON-RPC, and archival services. Ristretto255 range-proof verification becomes cheaper and supports larger batches, while the GraphQL subscription root moves into the production schema. Archival infrastructure gets broader package-query support through the Bigtable-backed gRPC service. This is a testnet release, not a live mainnet upgrade.
