Release Notes

nomiclabs/hardhat (@​nomiclabs/hardhat-solhint)

v4.0.0

Compare Source

This release is a major update. It fixes the issue of the check task always exiting with exit code 0, even if solhint reports errors (#​5057). It also updates the solhint dependency to v5.0.2.

Changes

• cc79bd7: Ensured the check task exits with exit code 1 when solhint raises any errors; this is a breaking change since the check task would previously always exit with exit code 0
• 9cae5e7: Updated solhint dependency to v5.0.2
