Major lint expansion across JS and CSS
Biome added a large batch of new nursery rules, including useMathTrunc, useMathAbs, useIteratorZip, noPathConcat, noDanglingUnderscore, noEagerArrayMethodsInLoops, and more. These tighten correctness and performance guidance across JavaScript and CSS, and several of them come with new migration mappings from ESLint/Stylelint to help users adopt Biome faster.
Framework-aware linting grows for Vue, React Native, and TanStack Query
The repo now has dedicated rules for Vue emit declarations, Vue typed refs, React Native platform colors, and TanStack Query rest destructuring. That work is paired with a new tanstackQuery domain and broader framework metadata, which makes the linter smarter about library-specific patterns instead of treating them as generic JS.
Vue semantic model lands and powers Vue rule refactors
Biome introduced a new Vue semantic model and wired HTML analysis into it, with follow-up changes in Vue lint rules to use semantic symbols instead of older declaration queries. This is a notable internal foundation shift that should make Vue analysis more precise and easier to extend going forward.
Formatter fix preserves parens for instantiation expressions
The JS formatter now keeps parentheses around looser operands of instantiation expressions when needed. This is a targeted correctness fix that prevents Biome from emitting code with altered meaning in TypeScript-heavy codebases.
