Release v5.19.1 (2026-09-15) · Rel1cx/eslint-react

What's Changed

react-x/immutability: the first parameter of a function is now classified as props only when the function is a confirmed component — one that returns JSX or calls hooks — so mutating the first parameter of a function that merely looks like a component (e.g. an event-handler factory whose returned function never renders and calls no hooks) is no longer reported. (#1952, closes #1951)

react-x/immutability: renamed MUTATING_METHODS/NAVIGATION_HOOKS to KNOWN_MUTATING_METHODS/KNOWN_MUTATING_HOOKS and added precise behavior boundary tests.
react-x/globals: restructured internals (split into collect, effects, and origins modules) to match the in-progress feat/environment-config implementation; no behavior change.
Website: awaited the async llms.txt index generation and fixed the website data update step to run before building.
CI: removed the generated file verification step.
Bumped typescript-eslint to 8.70.0, react/react-dom to 19.3.0, next to 16.3.5, vite to 8.3.0, effect to 3.22.2, fumadocs to 16.15.10, eslint-plugin-jsdoc to 64.3.9, tailwind-merge to 3.7.0, ansis to 4.4.0, nx to 23.2.1, eslint-plugin-react-refresh to 0.5.6, eslint-plugin-package-json to 1.8.1, @types/node to 26.5.1, @types/react to 19.3.0, @types/react-dom to 19.3.0, and pnpm to 12.4.1.
