7.0.1

• Disallowed passing inline useEffectEvent values as JSX props to guard against accidental propagation. (#34820 by @jf-eirinha)
• Switch to export = so eslint-plugin-react-hooks emits correct types for consumers in Node16 ESM projects. (#34949 by @karlhorky)
• Tightened the typing of configs.flat so the configs export is always defined. (#34950 by @poteto)
• Fix named import runtime errors. (#34951, #34953 by @karlhorky)

7.0.0

This release slims down presets to just 2 configurations (recommended and recommended-latest), and all compiler rules are enabled by default.

• Breaking: Removed recommended-latest-legacy and flat/recommended configs. The plugin now provides recommended (legacy and flat configs with all recommended rules), and recommended-latest (legacy and flat configs with all recommended rules plus new bleeding edge experimental compiler rules). (@poteto in #34757)

6.1.1

Note: 6.1.0 accidentally allowed use of recommended without flat config, causing errors when used with ESLint v9's defineConfig() helper. This has been fixed in 6.1.1.

• Fix recommended config for flat config compatibility. The recommended config has been converted to flat config format. Non-flat config users should use recommended-legacy instead. (@poteto in #34700)
• Add recommended-latest and recommended-latest-legacy configs that include React Compiler rules. (@poteto in #34675)
• Remove unused NoUnusedOptOutDirectives rule. (@poteto in #34703)
• Remove hermes-parser and dependency. (@poteto in #34719)
• Remove @babel/plugin-proposal-private-methods dependency. (@ArnaudBarre and @josephsavona in #34715)
• Update for Zod v3/v4 compatibility. (@kolian and @josephsavona in #34717)

6.1.0

Note: Version 6.0.0 was mistakenly released and immediately deprecated and untagged on npm. This is the first official 6.x major release and includes breaking changes.

• Breaking: Require Node.js 18 or newer. (@michaelfaith in #32458)
• Breaking: Flat config is now the default recommended preset. Legacy config moved to recommended-legacy. (@michaelfaith in #32457)
• New Violations: Disallow calling use within try/catch blocks. (@poteto in #34040)
• New Violations: Disallow calling useEffectEvent functions in arbitrary closures. (@jbrown215 in #33544)
