What’s New in v.1.9.0

  • Supported KIP-71 dynamic gas fee pricing mechanism. (#328, #327, #329, #330, #331, #334, #343, #344, #346)
    • Added effectiveGasPrice field to the response object of caver.rpc.klay.getTransactionReceipt.
    • Supported value-setting logic for undefined gasPrice with dynamic gas fee pricing mechanism introduced with the proposed Magma hard fork. Any undefined gasPrice will therefore be defaulted to baseFee * 2.
    • Supported tx.suggestGasPrice function in transaction instances to easily determine the gas price.
    • Added newly introduced KIP-71 governance parameters in the return object of caver.rpc.governance APIs.
    • Added newly introduced caver.rpc.klay.getUpperBoundGasPrice and caver.rpc.klay.getLowerBoundGasPrice APIs.
      Please see KIP-71 for details.
  • Supported some of the Admin API to control peers. (#320, #323)
    • caver.rpc.admin.getNodeInfo calls admin_datadir.
    • caver.rpc.admin.getPeers calls admin_peers.
    • caver.rpc.admin.addPeer calls admin_addPeer.
    • caver.rpc.admin.removePeer calls admin_removePeer.

Improvements

  • Updated web3j version to 4.8.8. (#305)
  • Added code examples of the caver.wallet package in javadoc. (#306)
  • Added net_version rpc call to caver.rpc.net. (#320)

Fixes

  • Updated DefaultGasProvider to implement ContractGasProvider to support dynamic gas price. If you are using DefaultGasProvider such as new DefaultGasProvider(), please change it to new DefaultGasProvider(caver), (#322)

Release v1.8.0

v1.8.0 Release Notes

What's New

  • In line with Klaytn's pursuit of Ethereum equivalence, Klaytn now supports Ethereum transaction types. But what is an update without SDKs? You can start using these transactions with caver, via caver.transaction.
    • Access lists are now available with TxTypeEthereumAccessList which was introduced with EIP-2930
      • The EthereumAccessList class is available in caver.transaction.ethereumAccessList as TxTypeEthereumAccessList.
    • The transaction type TxTypeEthereumDynamicFee presented in the proposal EIP-1559 is also available
      • The EthereumDynamicFee class is available in caver.transaction.ethereumDynamicFee as TxTypeEthereumDynamicFee.
  • The newly added klay namespace API functions are now available with caver via caver.rpc.klay!
    • caver.rpc.klay.getHeader
    • caver.rpc.klay.getFeeHistory
    • caver.rpc.klay.getMaxPriorityFeePerGas
    • caver.rpc.klay.createAccessList
  • You can use the ecsign function the new Ethereum transaction types.
    • The nitty-gritty: You have to sign the transaction types EthereumAccessList and EthereumDynamicFee via ecsign to generate the ECDSA signatures.
    • If you are inquisitive, the v in the signature values {v, r, s} for the new Ethreuem transaction types is a parity (0 for even, 1 for odd) of the y-value of the Secp256k1 curve, whereas the v in Klaytn contains chainId, making them incompatible.

Release v1.6.4

v1.6.4 Release Notes

What’s New

  • Good news: You can now use WebSocket to subscribe to events via publish/subscribe API with caver.java. (#278)
    • Subscribe to events using caver.rpc.klay.subscribe.
      • Use the parameters newheads to get notification for the latest block and logs for logs included in new blocks for specific contracts or events.
    • Of course, you can unsubscribe using caver.rpc.klay.unsubscribe.
    • Please refer to Klaytn Docs for more details.

Bug Fixes

  • Did you know that the hex prefix "0x" used to only work in lower case? Now it accepts upper case "0X" too. 271
  • We fortified the validation logic for the privateKey. 272, 275
  • We also made some improvements in the validation logic for caver.utils.compressedPublicKey, caver.utils.decompressedPublicKey274, 285
* In the rpc layer, the default value of the parameter isFullTransaction for the methods caver.rpc.getBlockByXXX used to be true, but now it’s set to false. 280
  • We fixed and improved the contract.once method. 282
    • The EventFilterOptions class has been refactored so that you can convert and manage subscription topics more easily.
    • Before, subscribing to an event returned only the raw data. Now with the new subscribeFlowable method, you can configure the data stream yourself, i.e. register callback methods for various cases.
