10.4.1 Latest
Latest

Node 10.4.1 integrates UTxO-HD into the Cardano node. UTxO-HD is a rework of the Consensus layer of the node which allows the UTxO set to be stored either fully in-memory (as with previous node versions) or else on some external storage medium (e.g. SSD or HD). The latter lowers the memory requirements of the running node at the cost of some speed. This first version of UTxO-HD provides an LMDB backend, but future releases will incorporate a more fine-tailored backend based on LSM trees. More information on UTxO-HD can be found in the consensus website.

This release also provides fixes and enhancements to the tracing system, to the location of LedgerDB configuration options, and to the node CLI and API. It also updates the dependency on Plutus to 1.45.

System testing results for the 10.4.1 release can be found on the corresponding tag testing page.

Benchmarking reports relevant to the 10.4.1 release can be found in this post on Cardano Updates.

Important

Users migrating from a previous version of the node should read the migration guide to properly configure the node and convert the database such that a replay from genesis can be avoided. Mainnet block producers and associated relays should only use the V2InMemory UTXO-HD backend.

This version of the node is mainnet ready. It is recommended for production use using the in-memory backend only.

Warning

The LMDB backend has not yet been benchmarked. While it may provide sufficient performance for edge nodes (wallets, explorers, exchanges etc.) at a valuable reduction in memory usage, it should not be used for block producer or relay nodes on mainnet.

Known Issues

There is a known bug with the experimental Ouroboros Genesis feature that is not yet recommended for mainnet use.
ChainSync Jumping (CSJ) is not disabled once a node is caught up. This should not affect normal operation of the syncing node, but does risk a DoS attack for the caught-up node. It will be corrected in a future release (Issue IntersectMBO/ouroboros-consensus#1490).

10.3.1

Node 10.3.1 primarily improves on performance: it improves execution speed, reduces memory usage and gives faster synchronisation times. In addition, it provides several enhancements to the new tracing system. It also provides support for light-weight checkpointing that is needed to enable ouroboros-genesis. Finally, it includes bug-fixes for a number of CLI commands. The docker images for node and submit-api have also received improvements to streamline operations.

System testing results for the 10.3.1 release can be found on the corresponding tag testing page.

Benchmarking reports relevant to the 10.3.1 release can be found in this post on Cardano Updates.

Known Issues

  • New tracing system: connectionManager_* metrics are incorrect; the underlying trace message ConnectionManagerCounters however logs the correct values.

  • New tracing system: slotsMissed metric is incorrect; it falsely counts slots since the most recent block production as missed. However, the block producer does not actually miss a slot.

  • GenesisMode: the optional peerSnapshotFile declaration in the topology file interprets relative paths with respect to node's binary directory rather than the topology file directory.

  • There is a known bug with the experimental Ouroboros Genesis feature that is not yet recommended for mainnet use.
    ChainSync Jumping (CSJ) is not disabled once a node is caught up. This should not affect normal operation of the syncing node, but does risk a DoS attack for the caught-up node. It will be corrected in a future release (Issue IntersectMBO/ouroboros-consensus#1490).

10.2.1

Node 10.2.1 provides support for the new tracing system and an initial integration of Ouroboros Genesis, a new feature which enables nodes to bootstrap from the network. It also provides a number of bug fixes and enhancements, including fixes and improvements to a number of CLI commands.

Benchmarking reports relevant to the 10.2.x release series can be found in this post on Cardano Updates.

Limitations

Note that lightweight checkpoints are not integrated into node 10.2.1, so it is recommended to only use Ouroboros Genesis for testing purposes (on e.g. Preview or PreProd) and not on Mainnet.

Known Issues

There is a known bug with the experimental Ouroboros Genesis feature that is not yet recommended for mainnet use.
ChainSync Jumping (CSJ) is not disabled once a node is caught up. This should not affect normal operation of the syncing node, but does risk a DoS attack for the caught-up node. It will be corrected in a future release (Issue IntersectMBO/ouroboros-consensus#1490).

Release Notes for cardano-cli (10.2.0.0 to 10.4.0.0)

Main changes

  • Added cardano-cli latest query ledger-peer-snapshot for a snapshot of big ledger peers used when syncing in Genesis
    (feature)
    PR 727

    A new query subcommand ledger-peer-snapshot was introduced to serialize a snapshot of big ledger peers. These relays will be relied on by network layer when a node is syncing up in Genesis consensus mode, since a node may not have any or up to date information from its own ledger which are the big ledger peer relays.

  • Added the debug check-node-configuration --node-configuration-file node-config.json command
    that reads node-config.json and checks that the hashes of genesis files are correct.
    (feature)
    PR 923 based on ADR 5

  • Added anchor data hash checks to transaction build
    (feature)
    PR 951

    This version adds a built-in check that allows cardano-cli to verify anchor data linked by a transaction at the time it is being built if using the command transaction build. The cardano-cli will automatically try to download the referenced anchor data, hash it, and check the obtained hash against the one in the transaction, letting the user know if there is a mismatch.

10.1.4

It is required that all Cardano stake pools and relays upgrade to this node version in order to mitigate a potential DoS attack following a hard fork to Protocol Version 10 ("Plomin" hard fork on mainnet). It is recommended that all other node users upgrade to this version. Node users who do not upgrade put themselves at risk of a potential DoS attack following the hard fork.

Node 10.1.4 is a mainnet-ready release of the Cardano node that is capable of crossing the Chang#2 ("Plomin") hard fork.
It adds safeguards at the mempool level to block specific types of transaction that could lead to a DoS attack following the hard fork.

For further details about cardano-node 10.1.4 please see the release notes for node versions 10.1.1, 10.1.2 and 10.1.3.

Benchmarking reports relevant to the 10.1.4 release can be found in this post on Cardano Updates.

10.1.3

This version of the node has been superseded by version 10.1.4, which has a critical fix. 10.1.3 users on Mainnet should upgrade to node version 10.1.4 prior to the Plomin (Chang#2) hard fork to avoid the risk of a potential DoS attack.

Node 10.1.3 is a mainnet-ready release of the Cardano node that is capable of crossing the Chang#2 hard fork. This update addresses a ledger issue where DRep delegations could be removed under some conditions. This inadvertently affected the ability to withdraw rewards in Protocol Version 10, and changed the stake distribution for some DReps.

For further details about cardano-node 10.1.3 please see the release notes for 10.1.1, since significant upgrades were performed compared to previous versions of the node.

10.1.2

Node 10.1.2 is a mainnet release of the Cardano node that is capable of crossing the Chang#2 hard fork. This update patches cardano-cli only, and does not change the node implementation. As described here, it restores some previous top level commands that were removed in node 10.1.1 such as query tip, which are widely used by SPOs and other node users.

For further details about cardano-node 10.1.2 please see the release notes for 10.1.1, since significant upgrades were performed compared to previous versions of the node.

10.1.1

Node 10.1.1 is a mainnet release of the Cardano node that is capable of crossing the Chang#2 hard fork. It includes a number of improvements to the governance system, including support for SPO delegation to pre-defined voting options, and support for auto-abstain DRep votes supplanting abstaining via rewards address delegation. It also enables new Plutus primitives as defined in CIP-0122, CIP-0123, and CIP-0127. Finally it includes a number of other improvements to the ledger, CLI, API and networking code bases, as detailed below.

Note that, although staking rewards will continue to be earned as usual, in order to withdraw their rewards, following the Chang#2 hard fork, Ada holders will need to delegate to a DRep, which may be one of the pre-defined options, a single key or a Plutus v3 script. Until the hard fork, rewards may be withdrawn normally. Although following the hard fork, rewards may not be withdrawn unless a DRep is delegated to, rewards will continue to accrue to the Ada holder normally, regardless of whether or not a DRep is delegated to.

Benchmarking reports relevant to the 10.1.1 release can be found in this post on Cardano Updates.

Release Notes for cardano-cli-10.1.1.0

Major Changes

  • Introduce "compatible" command group
    (feature, compatible)
    PR 917
Usage: cardano-cli compatible 
                                ( shelley
                                | allegra
                                | mary
                                | alonzo
                                | babbage
                                | conway
                                )

  Limited backward compatible commands for testing only.

Available options:
  -h,--help                Show this help text

Available commands:
  shelley                  Shelley era commands
  allegra                  Allegra era commands
  mary                     Mary era commands
  alonzo                   Alonzo era commands
  babbage                  Babbage era commands
  conway                   Conway era commands

This is a group of commands predominantly exposed for our testing requirements. It paves the way to deprecate all pre-mainnet eras from cardano-cli's interface as users are interested in interacting with the current era and the upcoming era if there is a hardfork on the horizon. Note, this does not imply that prior functionality introduced in previous eras will be unavailable.

  • Large deprecation of legacy commands and removal of related code.
    (breaking)
    PR 905

We waited until after the Chang hardfork to begin refactoring cardano-cli (internal code and the external interface). This is still ongoing work but the summary of the changes are as follows:

cardano-cli - General purpose command-line utility to interact with
cardano-node. Provides specific commands to manage keys, addresses, build &
submit transactions, certificates, etc.
 Usage: cardano-cli

+                     | compatible
                      )

Note:

  • Several of the era agnostic commands have been moved to the top level e.g key, address, node etc.

  • The majority of the legacy commands have been removed and we intend to fully remove the legacy command group in future releases.

Expect future changes to the cli's interface but note that we will be socializing proposed changes via our working group to get feedback from the community.

Features

  • Implement cddl's stake_reg_deleg_cert and vote_reg_deleg_cert and stake_vote_reg_deleg_cert as:

    • cardano-cli conway stake-address registration-and-delegation-certificate
    • cardano-cli conway stake-address registration-and-vote-delegation-certificate
    • cardano-cli conway stake-address registration-stake-and-vote-delegation-certificate
      (feature)
      PR 919

  • create-testnet-data now takes a node configuration file as input. If a file is given, it is augmented with the hashes (and paths) of the genesis files, or if the hashes/paths are present; they are checked.
    (feature, breaking)
    PR 908

  • Add anchor data hash checks to all governance action commands
    (feature, breaking, test)
    PR 915

  • Adding support for script stake credentials and stake address in create-treasury-withdrawal and improving help text. New options are: --funds-receiving-stake-script-file and --funds-receiving-stake-address

    tuning of the costs for reference scripts.
