Sui's testnet has been updated to version v1.75.1, bringing a set of protocol and data‑structure refinements. The release is documented on GitHub and targets developers working on the Sui ecosystem.
A key change is the introduction of protocol version 129. This new version adds explicit bounds for binary pools, replacing the previous implicit constraints. The update is purely internal and does not alter any user‑visible functionality.
The commit also adds two new methods to the sui::linked_table type: insert_before and insert_after. These methods allow developers to insert entries relative to existing keys, improving table manipulation flexibility.
Additionally, the sui::coin module now utilizes defining_ids. This adjustment refines how coin identifiers are handled within the protocol, potentially simplifying future extensions.
Node‑related updates are available in the repository, but the release notes do not detail specific validator or full‑node changes. Developers can review the linked GitHub pages for further information.
