1.33.0 -- December 2021

1.32.1 -- November 2021

  • Asset names are now rendered in a more consistent fashion in JSON output. Previously names which happened to be valid ASCII were rendered as such, and ones which were not resulted in unprintable characters. Now all names are rendered as hex. Future clients may choose to additionally render ASCII names if plausible to do so. (#3211)
  • Various testing improvements. (#3361)
  • Expose ledger events via the ledger state API. (#3374)

1.31.0 -- October 2021

  • Various internal improvements and refactorings. (#3163, #3253, #3288)

1.30.0 -- September 2021

  • Improvements to the ledger state API. (#3143)
  • Make it easier to use monadic queries. (#3151)
  • Implement 'getBlockHeader' for Alonzo. This was a stray function that got missed when implementing Alonzo in the API. (#3158)
  • A few additional exports for API consumers. (#3156)
  • Expose ledger events through the API. Ledger events provide a way for consumers to receive details about things that are happening inside the ledger, and will be used by tools such as db-sync. (#3085)
  • Improve the error message reported when you try to spend a non-Plutus locked input using a Plutus script. (#3187)

1.29.0 -- August 2021

  • Support for automated Tx building. (#2953)
  • A few additional exports for API consumers. (#3001, #3055)
  • Miscellaneous internal improvements. (#2948)
  • Block folding interface now derives the network ID automatically from the ledger config. (#2955, #2975)
  • Improve the error generated when a Tx output does not meet the minimum UTxO value. (#3027)
  • Add support for querying the Alonzo ledger state. (#2974)
  • Update the API documentation.

1.28.0 -- July 2021

  • Add a function 'getTransactionBodyContent'. This extracts a general view of the TxBody from the era-specific bodies. (#2663)
  • Add API support for new node queries:
    • QuerySystemStart gets the system start time.
    • QueryStakePools and QueryStakePoolParameters can be used to get details on the currently known stake pools.
    • QueryUTxOFilter provides various ways to query a filtered subset of the UTxO. (#2843)
  • Added functions to the API to assist in automated transaction building:
    • evaluateTransactionBalance computes the current balance of a (partial) transaction, which is helpful for determining what needs to be done to correctly balance it (such that value produced equals value consumed).
    • evaluateTransactionExecutionUnits computes how many ExUnits will be needed by all the scripts in a (partial) transaction.
    • evaluateTransactionFee computes the fee for a (partial) transaction, assuming a given number of VKey witnesses (corresponding to inputs).
    • estimateTransactionKeyWitnessCount attempts to estimate the number of VKey witnesses needed.
    • makeTransactionBodyAutoBalance attempts to create and automatically balance a transaction body, using the above tools. (#2906)
  • Miscellaneous internal improvements. (#2836, #2840)

1.27.0 -- April 2021

  • Add initial support for the ledger state and folding over blocks to the API. (#2633)
  • Scripts are now stored within the TxBody in the API, rather than in the witnesses. (#2547)

1.26.1 -- March 2021

  • The cardano-submit-api now takes transactions encoded as CBOR rather than JSON. This reverts a change to existing behaviour for backwards compatibility. (#2491, #2512)
  • Remove a backwards-compatibility workaround related to the optional query point (#2241 below) when querying the NodeLocalState. This had resulted in spurious notifications of disconnection in the logs. Note that as a consequence of this, instances of the CLI and other tools using the 1.26.1 API will fail to query node state from older versions of the node. (#2540)

1.26.0 -- March 2020

  • Added a demo for the use of cardano-client. This is an API to allow writing programs to interact with the cardano node. (#2295, #2303)
  • Removed code pertaining to the old IPC API (#2319)
  • Add the ability to calculate the minimum deposit needed for a transaction to the API, given a value. (#2325)
  • When querying the NodeLocalState, make the query point optional, and use the chain tip when not specified. (#2241)
  • Various internal improvements and refactoring (#2349, #2458)

1.25.0 -- January 2020

  • New IPC modules for easier interaction with the node, including support for all existing local state queries (#2230, #2238, #2263, #2277, #2286)

  • Make Cardano.Api the primary public module for the API.
  • API support for serialising multi-asset PolicyId and AssetName (#2270)
  • API for pretty-printing JSON output (#2103)
  • Improved tests for Byron era legacy key formats (#2259)
  • More precise error cases for tx outputs that are out of range (#2217)
