Version 2.1.0

  • Updated packages to their latest versions (updated @nomicfoundation/hardhat-verify to version 2.0.4).
  • Added a save function to the Deployer class to enable saving the contract to storage without deploying it.

Version 2.0.1

  • Fixed a bug where an instance of a storage object overwrote the state of another object in the file.
  • Changed the way of naming for Truffle transactions to txName.

Version 2.0.0

  • Removed redundant Hardhat Runtime Extensions.
  • Removed Verifier from Migrator class.
  • Revised the test infrastructure and architecture.
  • Fixed bugs related to the recovery of contract names.

Version 2.0.0-alpha.22

  • Enforce the overwriting in ArtifactStorage in the case of bytecodeHash as a key

Version 2.0.0-alpha.21

  • Fix a bug related to parsing the same bytecode for two different contracts

Version 2.0.0-alpha.20

  • Remove redundant initializers in a verifier task

Version 2.0.0-alpha.19

  • Handle the potentially undefined tx.customData.txName field

Version 2.0.0-alpha.18

  • Handle the partially linked Bytecode in the Truffle Adapter.

Version 2.0.0-alpha.17

  • Separated the logic of the Reporter and moved transaction-related functions to the TransactionRunner class.
  • Added the ability to specify a name for each transaction, essentially enabling the same transaction to be distinguishable. Also fixed a few bugs related to migration storage.

  • Should the name be located, the ContractFieldsToSave is disregarded and is not used as a key within the Transaction Storage.

Version 2.0.0-alpha.2

  • Library linking fully relies on the hardhat artifacts.

Version 2.0.0-alpha.1

This release represents a major update to our plugin. We have completely rebuilt the core logic from scratch, now using ethersV6. Additionally, we have conducted a comprehensive code walkthrough, addressing and resolving bugs, as well as introducing new features.

Breaking changes

  • Removed the logger from migrations. Logging functionality is now fully integrated within the plugin.
  • Restructured the arguments passed to the deploy function.
  • Transitioned to using the hardhat-verify plugin for contract verification.

Deployer

  • Added support for EthersV5, EthersV6, and TruffleV5 through Adapters.
  • Introduced types support for EthersV5 and EthersV6 only, including constructor arguments validation.
  • Implemented a library linking during contract deployment.
  • Enhanced reporting during contract deployment.
  • Enabled recoverability of contract deployments.
  • Improved error reporting during contract deployment.
  • Added special user storage between deployments.

Verifier

  • Utilized the hardhat-verify plugin for contract verification.
  • Added three types of verification: "immediately," "at-the-end," and "none."
  • Introduced Verification processor and Verification Storage to enable verification of all deployed contracts at the end of the migration.
  • Implemented verification error handling.
  • Utilized Reporter to override the default 'hardhat-verify' logging.

New tools

Reporter

Centralizes all console logging.

Storage

A module that stores necessary data for the migration process in a JSON file. The default path is the artifacts/build-info folder.
