Configuration Enhancements

Database Path Customization

• Separate Paths for Volatile and Immutable Databases: Users can now specify paths for volatile and immutable databases separately.

Command Line Options:

Users can specify database paths directly via command line:

[ --database-path FILEPATH
| --immutable-database-path FILEPATH --volatile-database-path FILEPATH
]

Configuration File:

Alternatively, paths can be set in the configuration YAML file under the "DatabaseFile" key:

"DatabasePath": {
  "ImmutableDbPath": "mainnetnode/db/node-imm",
  "VolatileDbPath": "mainnetnode/db/node-vol"
},

or for a single path configuration:

"DatabasePath": "mainnetsingle/db/node",

New tracing system

Major rework of the metrics naming schema

• Change all metric names to match those of the current tracing system, simplifying switching back and forth for existing integrations
• Augment metric names with type-spefic suffixes (like e.g. _int)
• Add optional Node config value TraceOptionMetricsPrefix (String) to specify a namespace prefix for metric names

• Add GetProposals and GetRatifyState queries.
• Add NodeToClientV_17 to supportedNodeToClientVersions.

• DRep registration expiration fix: #4547
• Use correct DRep threshold to ratify NoConfidence: 4516
• Added method to compute over-the-wire CBOR encoded transaction size needed for network layer: 4521
• Add governance related ledger state queries: 4514
• Improve Plutus debug functionality: 4503

• tx-submission mini-protocol now starts with a short delay, see #IntersectMBO/ouroboros-network#4927.

Features

• Script-based DRep Support on Update Certificate: Adds support for using a script-based decentralized representatives (DRep) in the update certificate command.
  PR 884

• Enhanced Transaction View: Modifies transaction view to show which inputs redeemers refer to, enhancing traceability.
  PR 861

Breaking Changes

• Propagate Experimental API: Propagates the experimental API to transaction build internals and deprecates pre-Conway eras for transaction build.
  PR 853
• Change in Default Behavior for Testnet Data Creation: The create-testnet-data command no longer defaults the --total-supply option. It now derives the total supply from the Shelley genesis file or uses half of that as the --delegated-supply if not specified.
  PR 874

Bugfixes

• Mandatory Treasury Withdrawal Fields: Makes the funds receiving address and amount mandatory for treasury withdrawal actions, fixing a potential oversight in command requirements.
  PR 877
• Prevent Overflow in Int Parsers: Addresses and forbids incorrect value entries in parsers for Int-like options to prevent silent overflows.
  PR 864
• Fix Estimated Fee Rendering: Corrects the estimated fee output format from Coin 357154 to 357154 Lovelace, improving clarity.
  PR 873

Features

• Upgrade Libraries: Upgrades to cardano-ledger-*, ouroboros-consensus-cardano, ouroboros-network-api, plutus-core, and plutus-ledger-api. PR 610
• New Types: Introduced newtype UnsignedTx and data Era to streamline era management for mainnet and upcoming eras. PR 604

Breaking Changes

• API Updates: Deprecated valueFromList, valueToList, and createAndValidateTransactionBody. Introduced IsList Value instance and recommend using createTransactionBody. PR 622 PR 597
• Transaction Changes: BalancedTxBody now returns UnsignedTx. PR 604
• Treasury Value Fix: Default value now set to Nothing instead of 0. Removed redundant type families in the Experimental API. PR 625

Bugfixes

• Fee Estimation: Fixed fee estimation when autobalancing minted assets. PR 622
• Data Handling: Included datums and redeemers in makeUnsignedTx. PR 623
• Datum Conversion: Fixed datum conversion in fromShelleyTxOut for ShelleyBasedEraAlonzo. PR 613

• Fixed a bug in the Plutus Core type normalizer in IntersectMBO/plutus#6272
• The case-of-case optimization on Plutus IR was removed from the compiler due to it causing OOMs: IntersectMBO/plutus#6248
• Removed Emitter and MonadEmitter, and changed the type of emit to Text -> BuiltinResult (): IntersectMBO/plutus#6224
• Forbade using EvaluationResult in the builtins code in favor of BuiltinResult, so that builtins throw errors with more helpful messages: IntersectMBO/plutus#5926
• Made [] :: [Integer], [] :: [Bool], [] :: [Data], and [(Data, Data)] compile directly to the respective empty list via the MkNil type class without usage of built-in functions or defineBuiltinTerm: IntersectMBO/plutus#6347
