Cardano Node 8.0.0

๐Ÿ““

Node 8.0.0 is a major release of the Cardano node that adds initial, experimental, support for the Conway ledger era (Protocol Version 9.0). It includes some additional CLI commands, bug fixes, and network configuration options. SPOs are recommended to deploy this version on all their nodes. This version of the Cardano node:

Introduces the Conway era (Voltaire) as a developmental hard fork. Note: the node does not have any Voltaire features yet, this just prepares the way by creating the transaction formats and providing the ability to hard fork into the era. Adds a governance action for SPO polls (cardano-cli governance poll) that the Cardano Foundation will use to conduct an SPO survey Introduces a fairness improvement into the mempool logic Adds query commands to inspect metrics and data in mempool Allows the network to be defined via CARDANO_NODE_NETWORK_ID instead of needing to be passed in every CLI query Adds more detailed output in the query tip CLI command Allows modification via configuration file of connection limits Provides versioned serialization formats for ledger Provides a ledger API Changes the tracking of deposits It also includes some bug fixes and performance improvements.

IMPORTANT: On mainnet, P2P networking is only intended to be ran on a single relay at this time. Please continue to run any other relays with P2P disabled using the legacy topology.

Please note that this version contains breaking changes
