## @eslint-react/eslint-plugin 5

### Breaking changes

- Class declarations in a component body are recognized as per-render constructions, so using one as a context value is reported. (5.28.3) — [release notes](https://github.com/Rel1cx/eslint-react/blob/80e6b4be530dcc532012116ba61eda53505c7779/CHANGELOG.md#v5283-2026-10-20)
- Identifier resolution is bounded by the enclosing component scope: render-scoped values in nested callbacks are detected, module-level values are treated as stable, and nested components report each value once from the innermost component. (5.28.3) — [release notes](https://github.com/Rel1cx/eslint-react/blob/80e6b4be530dcc532012116ba61eda53505c7779/CHANGELOG.md#v5283-2026-10-20)
- Class declarations in a component body are recognized as per-render constructions, so using one as a default prop is reported. (5.28.3) — [release notes](https://github.com/Rel1cx/eslint-react/blob/80e6b4be530dcc532012116ba61eda53505c7779/CHANGELOG.md#v5283-2026-10-20)

### Behavior and default changes

- General-purpose presets now enable JSX syntax support, so you no longer need to configure it yourself. (5.28.0) — [release notes](https://github.com/Rel1cx/eslint-react/blob/80e6b4be530dcc532012116ba61eda53505c7779/CHANGELOG.md#v5280-2026-10-16)

### Fixes and other changes

- Builtin member resolution no longer follows computed or unknown middle segments, preventing false reports of non-builtin calls. (5.28.8) — [release notes](https://github.com/Rel1cx/eslint-react/blob/80e6b4be530dcc532012116ba61eda53505c7779/CHANGELOG.md#v5288-2026-10-24)
- Now reports Date calls during render, including Date(), Date(arg), and window.Date(); unlike new Date(arg), Date(arg) always returns the current time. (5.28.7) — [release notes](https://github.com/Rel1cx/eslint-react/blob/80e6b4be530dcc532012116ba61eda53505c7779/CHANGELOG.md#v5287-2026-10-23)
- The ref-derived parameter exemption now also applies to helpers wrapped in useCallback. (5.28.6) — [release notes](https://github.com/Rel1cx/eslint-react/blob/80e6b4be530dcc532012116ba61eda53505c7779/CHANGELOG.md#v5286-2026-10-22)
- The suggested fix now adds rel="noreferrer" instead of rel="noreferrer noopener", because noreferrer already implies noopener; values combining both tokens remain valid. (5.28.5) — [release notes](https://github.com/Rel1cx/eslint-react/blob/80e6b4be530dcc532012116ba61eda53505c7779/CHANGELOG.md#v5285-2026-10-22)
- Reverted component-scope-bounded identifier resolution and per-component single-report attribution; class declarations in a component body remain recognized as per-render constructions. (5.28.4) — [release notes](https://github.com/Rel1cx/eslint-react/blob/80e6b4be530dcc532012116ba61eda53505c7779/CHANGELOG.md#v5284-2026-10-21)
- Reverted component-scope-bounded identifier resolution and per-component single-report attribution; class declarations in a component body remain recognized as per-render constructions. (5.28.4) — [release notes](https://github.com/Rel1cx/eslint-react/blob/80e6b4be530dcc532012116ba61eda53505c7779/CHANGELOG.md#v5284-2026-10-21)
- Identifier resolution is bounded by the enclosing component scope: render-scoped values in nested callbacks are detected, module-level values are treated as stable, and nested components report each value once from the innermost component. (5.28.3) — [release notes](https://github.com/Rel1cx/eslint-react/blob/80e6b4be530dcc532012116ba61eda53505c7779/CHANGELOG.md#v5283-2026-10-20)
- The script now emits YAML-safe quoted descriptions so scaffolded rules cannot reintroduce the website build failure. (5.28.2) — [release notes](https://github.com/Rel1cx/eslint-react/blob/80e6b4be530dcc532012116ba61eda53505c7779/CHANGELOG.md#v5282-2026-10-19)
- Stops reporting the React camelCase SVG prop renderingIntent as unknown, including when produced by the rule's autofix for rendering-intent. (5.28.1) — [release notes](https://github.com/Rel1cx/eslint-react/blob/80e6b4be530dcc532012116ba61eda53505c7779/CHANGELOG.md#v5281-2026-10-17)
