Cardano Node 8.2.0-pre Pre-release
Pre-release

NOTE: THIS RELEASE IS ONLY RECOMMENDED FOR USE ON THE SANCHONET AND PREVIEW PUBLIC TEST ENVIRONMENTS AT THIS TIME. IT IS NOT RECOMMENDED FOR USE ON THE PREPROD TEST ENVIRONMENT OR MAINNET.

Node 8.2.0 is a major release of the Cardano node. Updates to the ledger packages extend progress on the Conway ledger era to support new governance features via CIP-1694. Updates to the networking packages prepare the road for peer sharing. This release is phase 1 of the SanchoNet roll out that was referenced in the CIP-1694 workshop in Edinburgh on July 12 2023. It allows SPOs to vote on changes to the on-chain constitution. This release also adds the ability to start the node in block production mode with no secrets loaded using the --non-producing-node flag. This can be used to promote a backup block producer without having to restart the node, for example.

This version also fixes an issue with the ledger TICKF rule that caused loss of block producer synchronisation on SanchoNet.

Consensus *NONE*
Ledger
  • Restructure certificate interface
  • Conway related changes:
    • Introduction of a DRep with pre-defined DReps that vote No and Abstain.
    • Change DCert type to a TxCert type family and introduce new certificates
    • Implement voting on NewConstitution by StakePools as the most basic example of voting.
    • Implement query for getting Constitution hash from the ledger state.
    • Change structure of Governance Procedures in the TxBody
    • Fix TICKF rule, avoiding VRF verification and syncing issues
    • Clear out TxOuts with zero value from the UTxO upon translation into Conway
Network
  • Added --start-as-non-producing-node flag and implemented a way to enable block production dynamically: #5383, #5399. Note: we haven't yet verified if the performance regression of P2P BP nodes was fixed (ref).
  • Implemented an optional explicit warm valency for local root peers: #5409.
  • Implemented bootstraping for peer sharing (also known as light peer sharing): IntersectMBO/ouroboros-network#3596; new trace is included: TraceKnownInboundConnection which is emitted when an inbound peer is shared with the outbound governor (and thus it could be used as an upstream peer).
  • Renamed FetchDeclineChainNoIntersection as FetchDeclineChainIntersectionTooDeep: IntersectMBO/ouroboros-network#4608.
  • We limit concurrency used by dns resolution in P2P mode. We only resolve up to 8 dns names
    concurrently for public / ledger peers and up to 2 for local root peers.
    This will affect how quickly node connects to ledger peers when it starts. IntersectMBO/ouroboros-network#4596.
  • Improved memory footprint of peer metrics: IntersectMBO/ouroboros-network#4620.
  • We turned on by default the following traces:
    • LocalConnectionManagerTracer
    • LocalInboundGovernor
    • LocalHandshake
    • LocalServer
    • Server
      See #5353
Cardano-cli

  • cardano-cli split out to a separate repository

  • Era-sensitive command structure

  • Set default era to Babbage in stake-address, stake-pool and governance commands

  • CARDANO_ERA environment variable support

  • Make it build with ghc-9.6

  • Add a query for the hash of the constitution

  • Update cardano-cli with the ability to create votes and governance actions.
    Update transaction build with the ability to specify votes and governance actions.

  • The --protocol-params-file option of the transaction build command is
    now marked as deprecated in Usage help. The option was already deprecated
    and ignored.

  • cardano-cli ping changes:

    • timestamp format changed to ISO8601
    • added --query-versions flag, instread of doing version negotiation the remote
      side will reply with its set of supported versions.
    • fixed support for node-to-client mini-protocol over Unix socket.

  • Add --conway-era flag.

Cardano Node 8.1.0 Pre-release
Pre-release

THIS RELEASE IS NOT RECOMMENDED FOR USE ON ANY NETWORKS
Node 8.1.0 is a major release of the Cardano node. Updates to the ledger packages extend progress on the Conway ledger era, including the introduction of Plutus V3. They also improve performance at the epoch boundary, resolving a long-standing issue where a large computation was disrupting the block leader check (see #4421). Updates to the networking packages introduce a new query to the handshake, which is helpful for debugging. The cardano-api has been moved to a separate repository.

NOTE Because of P2P bug fix, this is superseded by 8.1.1

The release also includes a number of bug fixes and further performance improvements.
In particular, a DNS issue was partially resolved which affected peer-to-peer networking.

Please note that this version contains breaking changes

  • The ledger state serialization has been changed to accommodate the Conway ledger era
  • The Ping command now takes a new parameter, query.

Known Issues

  • Please see list of 8.1.0 issues
  • If there's no DNS name in any of the local root groups of P2P topology, then all ip addresses will be ignored

  • Fix query serialization for backwards compatibility. The GetCurrentPParams query now uses the legacy en-/decoding for its result again when the NodeToClientVersion is <15, restoring compatibility with older clients.
  • Optimise GetStakeSnapshots query to not traverse all delegations
    per stake pool, but instead compute the total stake per pool in a
    map and do a lookup
  • Fix performance regression of GetFilteredDelegationsAndRewardAccounts query.
  • Introduce NodeToClientV_15 that enables the deposits query.
  • Increase the minimum reconnection delay from 0s to 10s.
Ledger
  • Plutus V3 support, only available in the conway ledger era.
  • PState is now parametric in era, not crypto.
  • Adjust for new conway era certificates.
  • Ledger UMapCompact is now UMap
  • Ledger types with names involving DState are renamed to CertState.

Cardano Node 8.0.0

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

  • Needs newer libsodium-vrf revision dbb48cce5429cb6585c9034f002568964f1ce567

Consensus
  • The transactions in the mempool are now guaranteed to be processed irrespective of their sizes. This change also caused tryAddTxs to be removed in favour of a new addTx function.
Ledger
  • The provenance for the reward calculation has been removed. The type signature to the API function getRewardProvenance has not changed, it just returns an empty provenance value.
  • We have created a Ledger API, with the aim of providing a user-friendly interface to the ledger libraries. See here.
  • The initial funds and staking in the Shelley genesis type (used only for testing) now use ListMap instead of Map.
  • There is a new calculatePoolDistr' function which is similar to calculatePoolDistr but has a new filter argument to only include the stake pool ids (stake pool key hashes) that are needed.
  • The ledger events are not guaranteed to appear in any given order within a block. For this reason, motivated by the use case in db-sync, the TotalDeposits event now includes a transaction ID and emits the change in deposits instead of the value.
  • We changed the way deposits are tracked. See here for the details.
  • We changed the API function Cardano.Ledger.Shelley.API.Wallet(evaluateTransactionBalance) to take DPState as input. This can no longer be computed without the DPState
  • Some noticeable changes have been made which will only become apparent starting at major protocol version 9:
    • There is a new ledger era, namely conway.
    • We now have the ability to more easily change serializations when the major protocol version changes. Though this change is not immediately visible to the node, it enables visible changes in the future. See CIP-80 For the deprecation cycle.
    • Pointer addresses will no longer accrue rewards starting with version 9.
    • We fixed the incorrect conversion of the validity interval's upper bound in transVITime.
    • Starting in version 9, duplicate keys in CBOR maps and sets are no longer allowed.
    • Starting in version 9, CostModels can now be deserialized from any map of Word8 values to lists of integers. Only valid cost models are actually converted to evaluation contexts that can be used. Errors and unrecognized language versions are stored in the CostModel type so that:
      • They can accept cost models that they do not yet understand.
      • Upon deserializing after a software update, new cost models are available from the prior serialization.
Network
Cardano-cli
  • cardano-cli provides ping command, which previous was available as a standalone cardano-ping executable.
  • Rename TestEnableDevelopmentHardForkEras to ExperimentalHardForksEnabled and TestEnableDevelopmentNetworkProtocols to ExperimentalProtocolsEnabled
  • Auto-balance multi asset transactions
  • Default to the ledger's CDDL format for transaction body creation by removing flags --cddl-format and --cli-format from build and build-raw
  • Update create-staked with the ability to specify relays for all created stake pools
Cardano-api
  • Append, not prepend change output when balancing a transaction
  • Preserve ScriptData bytes with HashableScriptData
  • Remove distinction between multisig and timelock scripts
