Protocol
Sui Protocol Version in this release: 127
#26896: added protocol version 127 enabling always_advance_dkg_to_resolution. Corrects version 126 which was incorrectly modified after being released to testnet.
#26901: Updated gas prices for range proof verification and Ristretto group operations in protocol version 127.
#26998: Enable Ristretto255 group operations and bulletproofs range proof verification on testnet.
#26996: Mainnet switches to timestamp-based epoch close at protocol version 127. No operator action required.
Nodes (Validators and Full nodes)
#26973: A node now reports and disconnects state-sync peers that are consistently unreachable even when it is not actively syncing from them; previously this could fail to happen. No operator action required.
#26989: Fixes a spurious panic that could occur during a normal node shutdown/restart. No action required.
gRPC
#26763: `SimulateTransaction` now accepts `gas_price=0` for gasless-tier-eligible transactions (both via the unresolved proto path and as pre-built BCS transactions) instead of returning an error.
CLI
#26991: adds sui move lint command
#27012: Renamed the --forking-mode flag to --skip-signing to more correctly represent what it does.
