Cardano has announced the release of Node v11.0.1, marking a significant step towards the Van Rossem hard fork. The upgrade, which is crucial for the mainnet hard fork, requires ecosystem participants to update from node v10.7.1, as the older version cannot cross the protocol version 11.0 boundary. The differences between the two versions are minimal, ensuring a smooth transition. The Van Rossem hard fork is entering its first live-governance-driven activation phase, with the Plutus cost model protocol parameter update submitted for approval. The target effective date for this update is May 21. Meanwhile, Cardano's ADA token has seen a 2.18% decline in the past 24 hours, trading at $0.278, but has gained 11.88% over the past week. The price remains in a consolidation phase, with key levels at $0.25 and $0.22.
