What's New
Protocol v138 removes transaction dependency reporting and adds GraphQL/CLI features
Breaking Changes
- Transaction effects no longer report dependencies; the effects encoding retains an empty dependency vector.
- Fullnodes no longer restrict simulated transactions to their preferred proposers by default.
- Validators now pull transactions from a consensus-side pool at block proposal time instead of the admission queue.
New Features
- GraphQL query multiGetDynamicFields for fetching multiple dynamic fields.
- GraphQL fields derivedObject and multiGetDerivedObjects for addressable objects.
- CLI command withdrawal for address balance withdrawals in PTBs.
- Test helper functions withdraw_balance_from_address and settled_balance.
- Metric epoch_execution_time_observer_tracked_object_utilization for tracking specific object utilization.
Improvements
- gRPC improvements for Rosetta prevent transient checkpoint failures on fullnodes.
- New memory invariant check for reference/value usage in PTBs.
- Colliding deferred-transaction keys in the consensus handler merge their entries instead of overwriting.
- Optional object-utilization-metric-tracked-ids configuration for detailed tracking.
Upgrade Notes
Upgrading to protocol v138 removes transaction dependency reporting from effects (empty vector). Fullnodes now allow simulated transactions from any proposer by default. Validators must adapt to pulling transactions from the consensus-side pool during block proposal.
