Release Notes

NomicFoundation/hardhat (hardhat)

v3.7.0

Compare Source

Minor Changes

• #​8200 ce430ac Thanks @​tenderdeve! - Hardhat 3 is now stable, the "Beta" wording is being dropped from the hardhat --init process and project templates.

v3.6.0

Compare Source

Minor Changes

• #​8327 dee44f6 Thanks @​alcuadrado! - Add a cleanupArtifacts option to SolidityBuildSystem#build. When true, the build system runs cleanupArtifacts against the build's root file paths after a successful build, deleting orphan artifacts and unreachable build-info files for the scope.

• #​8327 dee44f6 Thanks @​alcuadrado! - Deprecate the following SolidityHooks: getCompiler, onCleanUpArtifacts, preprocessProjectFileBeforeBuilding, preprocessSolcInputBeforeBuilding, readSourceFile, invokeSolc, and readNpmPackageRemappings. They will be removed in a future release.

  Use processArtifactsAfterSuccessfulBuild instead of onCleanUpArtifacts, and getCompilationJobErrors instead of invokeSolc.

• #​8327 dee44f6 Thanks @​alcuadrado! - Add SolidityHooks#getCompilationJobErrors hook, which lets plugins process the compiler output errors of a compilation job before they are reported to the user.

• #​8327 dee44f6 Thanks @​alcuadrado! - Add SolidityHooks#processArtifactsAfterSuccessfulBuild hook to let plugins post-process the artifacts. The hook receives the resolved build options as a new exported ResolvedBuildOptions type.

Patch Changes

• #​8327 dee44f6 Thanks @​alcuadrado! - SolidityBuildSystem#cleanupArtifacts now returns the list of artifact paths that remain after the cleanup.

• #​8335 a4bf547 Thanks @​gultekinmakif! - Allow STRING_WITHOUT_DEFAULT and FILE_WITHOUT_DEFAULT as positional arguments

• #​8326 959f2e1 Thanks @​kanej! - Fixed hardhat flatten silently producing a misleading output for projects with cyclic Solidity dependencies.

• #​8262 d3ba170 Thanks @​fvictorio! - Add AGENTS.md and agentic skills to sample projects

• Updated dependencies:

  • @​nomicfoundation/hardhat-utils@​4.1.3
  • @​nomicfoundation/hardhat-errors@​3.0.14

v3.5.1

Compare Source

Patch Changes

• #​8316 971a135 Thanks @​alcuadrado! - Fix hardhat --init when used with pnpm 11

• #​8302 fb99caa Thanks @​ChristopherDedominici! - Suppress solc warnings that are direct side effects of --coverage instrumentation.

• #​8315 90650fd Thanks @​schaable! - Improved error messages for common migration errors.

v3.5.0

Compare Source

Minor Changes

• #​8301 793cc84 Thanks @​kanej! - Disable transaction gas cap and block gas limit when running tests under --coverage.

• #​8270 cf2823b Thanks @​schaable! - Solidity test configuration now also accepts { profiles: { default: ... } }. Only the default profile is currently supported, other profile names will be supported in a future release. The previous flat shape continues to work unchanged.

  The resolved HardhatConfig.test.solidity is now profile-keyed: read per-profile fields at hre.config.test.solidity.profiles.default.* instead of hre.config.test.solidity.*. Plugins that read the resolved Solidity test config need to be updated.

Patch Changes

• #​8298 83b1ae1 Thanks @​Wodann! - - Fixed a bug when using a test filter where the setUp function would be run for empty test suites

  • Fixed a bug where snapshot cheatcodes would throw an error if names were invalid
  • Fixed coverage instrumentation interfering with the single-call vm.prank cheatcode
  • Added support for instrumentation of Solidity 0.8.35

• #​8264 8452f97 Thanks @​alcuadrado! - Export ./package.json so consumers can import the package's manifest.

• #​8310 9f394ec Thanks @​js360000! - Fix JSON-RPC error.data shape for revert errors (code 3): return the raw revert hex string directly instead of a { message, txHash, data } wrapper object. This matches the geth/anvil/EVM-node convention that client tooling (viem, ethers, web3.js) relies on when decoding custom errors. Closes #​8075.

• #​8269 045cb8d Thanks @​alcuadrado! - Always load the builtin plugins' type extensions

• #​8243 08805db Thanks @​ChristopherDedominici! - Support EIP-712 cheatcodes in Solidity Test.

• #​8259 1d1204f Thanks @​kanej! - Fixed build overrides not being respected when running compile

• #​8188 d48bbfd Thanks @​alcuadrado! - Add --init --template <template-name> to initialize projects in a non-interactive way. Also add --init --templates to get the list of template names.

• #​8290 3a15b11 Thanks @​gultekinmakif! - Fixed abstract contracts being picked up as test suites by the Solidity test runner (#​8203).

• #​8266 325bae1 Thanks @​schaable! - Sanitized snapshot cheatcode group names to avoid issues when persisting them to disk. A warning is shown when a group is renamed suggesting the user to update their snapshot group names to match the on-disk names.

• #​8312 76c15ff Thanks @​alcuadrado! - Update the Hardhat 3 TypeScript project templates for TypeScript 6.
