According to NewsBTC, Cardano continued developing Leios, a scaling project involving the production of endorser blocks, certificate verification and vote transmission.
The rc-2026w44 prototype added adaptive endorsements, while an update to ouroboros-consensus is expected to reduce memory usage when writing ledger snapshots. These changes do not yet mean that Leios has launched on mainnet.
A separate Hydra report detailed monitoring improvements and bug fixes. The Plutus team added 65 conformance tests for new built-in Value operations.
