Charles Hoskinson said June will likely be the time when Cardano Node reaches version 9.0. This means that Cardano is ready for the Chang hard fork upgrade and is waiting for 70% of SPO (Stake Pool Operators) to install the new node. Chang hard fork will bring Cardano into the Voltaire Age.

The Voltaire era will focus on decentralized governance and it has 2 parts:

Chang upgrade#1will deploy governance features on Cardano, initiating the technical launch phase outlined in CIP 1694. This phase establishes the foundation for decentralized voting and governance.

Chang upgrade No. 2 will take CIP 1694 out of the technical launch phase, unlocking the final features of on-chain governance, including proxy participation and treasury withdrawals. This is an important step forward, as it empowers the community to propose and fund new projects in the Cardano ecosystem.
