2.9.1

Patch Changes

  • 69a6434e: Fix a bug that made Hardhat Network hang when connecting MetaMask (#2380)

2.9.0

Minor Changes

  • bf017963: Add a new RPC method, hardhat_mine, which supports the mining of multiple blocks in a single call (#1112)

  • 345ebab7: The test task now supports a --parallel flag to run tests in parallel. There are also two other new flags: --bail, to stop the execution after the first test failure, and --grep, to filter which tests should be run.

    To support running tests in parallel, the version of mocha used by Hardhat was upgraded to its latest version. This should be a mostly backward-compatible change, but there could be some edge cases where this breaks existing tests.
