The Sui devnet has been updated to version 1.81.0, marking a significant milestone in the development of the Sui protocol. This release brings a range of improvements and updates, including changes to the gas model, memory invariant checks, and enhancements to transaction effects and node configurations.
One of the key updates in this release is the addition of a new memory invariant check for reference/value usage in PTBs. This change is aimed at improving the security and reliability of the Sui protocol. Additionally, the release includes updates to the gas model, which will help to optimize transaction processing and reduce congestion on the network.
The update also includes improvements to transaction effects, which will enable more efficient and accurate processing of transactions. Specifically, transaction effects no longer report transaction dependencies, and object versions and per-object previous-transaction metadata remain unchanged.
In terms of node configurations, the release includes updates to the execution-time-observer-config and the consensus-transaction-pool. The execution-time-observer-config now includes an optional map from object ID to name, which will help to improve the reporting of object utilization metrics. The consensus-transaction-pool has also been updated to enable validators to pull transactions from a consensus-side pool at block proposal time.
The release also includes updates to the gRPC and GraphQL APIs. The gRPC API now fetches latest checkpoint data in one request, preventing transient failures when fullnodes behind a load balancer have different heights. The GraphQL API has been updated to include new fields and functions, including `derivedObject` and `multiGetDerivedObjects`.
Overall, the Sui devnet upgrade to version 1.81.0 represents a significant step forward in the development of the Sui protocol. The updates and improvements included in this release will help to improve the security, reliability, and efficiency of the network, and will pave the way for future growth and development.
