- react/index.js: @eslint-react recommended config + jsx-a11y-x + hooks
- react/rules.js: @eslint-react/ rule prefixes, @stylistic/jsx-self-closing-comp, jsx-a11y-x/ prefixes

Node 20 reached EOL on April 30, 2026. Package engine now requires >=20.19.0, so remove 20.x from test matrix and update dependency-check and publish jobs to Node 22 LTS.
Node 26.0.0 was released May 5, 2026 as the Current release. Adding to the test matrix ensures compatibility is caught early before it enters Active LTS in October 2026.
- Add comprehensive rule prefix migration guide to CHANGELOG - Backfill missing 6.x version history - Add Requirements section to README (Node >=20.19.0, ESLint >=10) - Update install command from eslint@9 to eslint@10
- actions/checkout: v5 → v6.0.3 (9f69817) - actions/setup-node: v5 → v6.4.0 (48b55a0) - github/codeql-action: v4 → v4.36.2 (1a818fd) All actions now pinned by immutable commit SHA with version comments for supply chain security.
- Bump version from 5.0.0 to 7.0.0 - ESLint 9+ → 10+ references - Replace old plugin names with new ones (import-x, @eslint-react, jsx-a11y-x) - Update CI matrix to 22.x/24.x/26.x - Mention SHA-pinned actions - Replace inline version history with CHANGELOG link - Add plugin rename note to Common Tasks
