Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
Concordium node version 8.0.3 contains support for protocol version 8. The new consensus protocol will take effect on the testnet on February 24, 2025. Node runners should upgrade to version 8.0.3 before the protocol update to ensure that their nodes do not shut down. Validators in particular are encouraged to update their nodes, as the new protocol introduces suspension of inactive validators, meaning that failing to update may result in your validator being suspended.
Protocol version 8 introduces the following changes:
Validators are automatically suspended if they do not produce blocks for a certain number of rounds.
The configure-validator transaction can suspend or resume a validator, including adding a validator in a suspended state.
Suspended validators are paused from participating in the consensus algorithm.
Additionally, the node release includes a number of fixes and improvements:
Add suspension info to BakerPoolStatus / CurrentPaydayBakerPoolStatus query results.
Add GetConsensusDetailedStatus gRPC endpoint for getting detailed information on the status of the consensus, at consensus version 1.
Update Rust version to 1.82.
Update GHC version to 9.6.6 (LTS-22.39).
Add GetScheduledReleaseAccounts endpoint for querying the list of accounts that have scheduled releases.
Add GetCooldownAccounts, GetPreCooldownAccounts and GetPrePreCooldownAccounts endpoints for querying the lists of accounts that have pending cooldowns in protocol version 7 onwards.
gRPC endpoints DryRun, GetBlockItemStatus and GetBlockTransactionEvents now report the parameter used to initialize a smart contract instance as part of a ContractInitializedEvent.
Fix a bug where, after a protocol update in consensus version 1 (P6 onwards), a node may miscalculate the absolute height of blocks when it is restarted.
Fix a bug where GetBlockInfo reports the parent block of a genesis block to be the last finalized block of the previous genesis index, instead of the terminal block.
