Bun runtime and module support expands linting (
c5c8315, a20f44a)
Biome now understands Bun-builtins across import resolution and linting, so rules like noUnresolvedImports, noUndeclaredDependencies, and the Node-module checker stop flagging Bun runtime modules such as bun:sqlite and bun:test. A new noBunModules nursery rule also lands to explicitly forbid Bun builtins where desired, making runtime-specific module handling much more precise.
New noThisOutsideOfClass JS rule (
1fc42ed)
Biome adds a nursery lint rule that reports this used outside class members, while still allowing TypeScript functions with an explicit this parameter. The commit also wires the rule into ESLint migration/configuration metadata and adds full JS/TS coverage.
Vue deprecated scoped slots rule added (6c7fd27)
A new Vue nursery rule flags deprecated $scopedSlots usage and can suggest an unsafe $slots replacement. This broadens Biome’s framework-specific linting and includes backend/schema wiring plus migration support from ESLint.
Malformed for...of parsing no longer crashes (
6586ceb)
Biome fixes a parser recovery bug that could crash linting on malformed for...of input. The parser now classifies certain broken arrow-like constructs as bogus expressions, improving resilience on invalid code.
noUnusedVariables now handles merged interfaces correctly (a689cb5, 65742b3)
Two fixes tighten TypeScript unused-variable analysis around interface merging and namespace merging. That prevents false positives in patterns that intentionally split declarations across multiple interface/namespace blocks.
CSS parser/analysis gets several correctness fixes (
15350fc, d4a0716, b6611dd)
Biome fixes SCSS nesting recovery, legacy IE filter parsing/formatting, and duplicate-property detection across nested at-rules. These changes improve both parser robustness and lint accuracy on real-world CSS/Sass edge cases.
Grit plugins can now use function = ... node arguments (67963b4)
Biome’s Grit parser and CLI regression coverage were updated so plugins can use function = ... in node arguments. This unblocks a parser bug that previously rejected valid plugin patterns.
