Mysten Labs has published the Sui mainnet release v1.74.1, advancing the protocol to version 128. The primary change in this version is the introduction of explicit bounds for binary pools, which were previously constrained only implicitly. This adjustment does not affect end‑user functionality but clarifies internal pool mechanics for developers.
The release also incorporates changes from protocol version 127, which adds the always_advance_dkg_to_resolution flag. This flag enables deterministic progression of the distributed key generation process to its resolution stage, improving consistency across network participants.
Additionally, the update corrects an earlier mistake in version 126, which had been unintentionally altered after its deployment on testnet. The correction ensures that version numbering and feature sets remain aligned with the intended roadmap.
No direct user‑visible alterations are expected, but developers should review the updated repository pull requests for detailed implementation notes. The full changes are available on the Sui GitHub releases page.
Stakeholders are encouraged to monitor upcoming releases for further protocol refinements and to test any integration impacts in a controlled environment before deploying to production.
