Scheduled

We are upgrading our Sui Testnet infrastructure to v1.78.1. This release introduces protocol version 135, which disables defer_unpaid_amplification on all networks and applies v134's original_package_id costs and consensus block limits on mainnet.

The upgrade includes improvements to gRPC error messaging, GraphQL subscription and query reliability, and Move compiler bug fixes.

During the maintenance window, brief interruptions to RPC availability may occur.

RPC Changes:
- TransactionExecutionService simulate/resolve — Error messages for version-mismatch and digest-mismatch now include the offending object ID and render provided/actual values consistently for better debugging.
- GraphQL transactions subscription — Transaction subscriptions can now be created from a historical cursor, enabling catch-up and replay of transaction streams from a specific point in time.
- GraphQL transactions and events queries — Fixed a race condition where these queries could non-deterministically omit recently-created data when served via --ledger-grpc-url.
