## eslint-plugin-react-refresh 0.5

### Breaking changes

- The package now requires ESLint 9. (0.5.0) — [release notes](https://github.com/ArnaudBarre/eslint-plugin-react-refresh/releases/tag/v0.5.0)
- Replaces `customHOCs`; use it to specify additional HOCs for validation. (0.5.0) — [release notes](https://github.com/ArnaudBarre/eslint-plugin-react-refresh/releases/tag/v0.5.0)
- HOC call validation is stricter, distinguishing actual React HOC calls from random call expressions; add HOCs such as `connect` or `styled` to `extraHOCs` when needed. (0.5.0) — [release notes](https://github.com/ArnaudBarre/eslint-plugin-react-refresh/releases/tag/v0.5.0)
- The package now requires Node 20. (0.5.0) — [release notes](https://github.com/ArnaudBarre/eslint-plugin-react-refresh/releases/tag/v0.5.0)

### New APIs and options

- Adds an option that suppresses warnings when components are exported together in an object; every member must be a component, and anonymous functions need a component name as key. Defaults to false, or true in vite config. (0.5.7) — [release notes](https://github.com/ArnaudBarre/eslint-plugin-react-refresh/releases/tag/v0.5.7)
- Add instant to allowExportNames in Next config. (0.5.4) — [release notes](https://github.com/ArnaudBarre/eslint-plugin-react-refresh/releases/tag/v0.5.4)
- A named export provides the plugin object and configuration presets; its preset functions accept custom options, merge them with defaults, and return a config object. (0.5.0) — [release notes](https://github.com/ArnaudBarre/eslint-plugin-react-refresh/releases/tag/v0.5.0)

### Behavior and default changes

- The Next config allowExportNames list now includes contentType and size. (0.5.5) — [release notes](https://github.com/ArnaudBarre/eslint-plugin-react-refresh/releases/tag/v0.5.5)
- Supports nested function calls for extraHOCs. (0.5.1) — [release notes](https://github.com/ArnaudBarre/eslint-plugin-react-refresh/releases/tag/v0.5.2), [release notes](https://github.com/ArnaudBarre/eslint-plugin-react-refresh/releases/tag/v0.5.1)

- Fixes detection of non-component classes exported via export { }. (0.5.3) — [release notes](https://github.com/ArnaudBarre/eslint-plugin-react-refresh/releases/tag/v0.5.3)
- False positives with TypeScript function overloading are supported. (0.5.1) — [release notes](https://github.com/ArnaudBarre/eslint-plugin-react-refresh/releases/tag/v0.5.1)
- The rule now handles ternaries and chained HOC patterns such as `customHOC(props)(Component)`, allowing it to correctly support those files. (0.5.0) — [release notes](https://github.com/ArnaudBarre/eslint-plugin-react-refresh/releases/tag/v0.5.0)
