    A protocol update to implement smart contract upgradability and performance improvements will take effect on mainnet on December 13, 2022.

    New node software compliant with the protocol update is released for Linux, Windows, and MacOS here.

    The new node version also fixes a security issue in node version 4. Therefore, we strongly recommend all nodes to get updated as soon as possible after the node release and latest before the protocol update on December 13. Old nodes will stop processing new blocks at that point.

    For more details on the protocol update, see concordium-update-proposals. The security advisory describing the security issue will be published on December 13.
