Concordium Node has been released for testnet in version 7.0.4
This is a major release that contains support for protocol version 7. This protocol version introduces changes to stake cooldown behaviour, disables shielded transfers, reduces smart contract execution costs, adds new smart contract functionality, and redefines the block hashing scheme.
The protocol update will be effective on testnet on September 30th. Node runners MUST upgrade to version 7.0.4 before the protocol update to ensure that their nodes do not shut down. The node release and protocol update on testnet are in preparation for a similar node release and protocol update on mainnet, which are planned for October 3rd and October 30th respectively.
This release also includes improvements and bug fixes, details of which are in the release notes.
