What's New

Upgrade to protocol v137 adds allowances, gas cost adjustments, and PTB reference checks.

Breaking Changes

  • The derivation of SuiTransactionBlockEffects.shared_objects changed to include implicitly read system objects.

New Features

  • New allowances feature for transaction management.
  • Support for public(package) constants in Move packages.
  • New memory invariant check for reference/value usage in PTBs.
  • TransactionExpiration::Validity now accepted on all networks.
  • Archival gRPC service now serves MovePackageService endpoints.

Improvements

  • Gas cost adjustments for LdConst abstract value size.
  • Object-funds withdrawal checks enabled on devnet.
  • Consensus transaction pool optimization for validators.
  • gRPC services enhanced with V1 effect details.
  • Ristretto255 range proof verification is cheaper.

Upgrade Notes

Consumers must filter SuiTransactionBlockEffects.shared_objects against transaction inputs as it may include implicitly read system objects. Gas costs for LdConst have increased slightly due to abstract value size calculation.
