New JS rule enforces Error objects in Promise rejections (
9bbff0c)
Biome now ships usePromiseRejectErrors, a nursery lint rule that flags Promise.reject(...) and rejection paths that use non-Error values. The rule is wired into configuration, diagnostics, migration mapping, and the public schema, so it can be enabled and surfaced consistently across the toolchain.
New nursery rule bans self-imports (
81b0adb)
noSelfImport was added to catch modules importing themselves, a common source of accidental circular or nonsensical imports. The rule is fully registered in config, diagnostics, and ESLint migration support, and includes dedicated tests.
Tailwind arbitrary-value checks now use shared syntax detection (0884e29)
noTailwindArbitraryValue was refactored to rely on the shared Tailwind syntax query instead of its own attribute parsing and Tailwind parser path. This also removes the rule’s attributes and functions options, simplifying the API while aligning detection with other Tailwind-based rules.
Rule-doc analyzer now handles HTML-like snippets for JS rules (
17a2560)
Biome improved documentation snippet analysis so JavaScript rule docs can include HTML-like embedded examples, including Astro cases. This makes rule docs more accurate and reduces false failures when validating embedded examples.
Other misc changes
- Updated the Tailwind v4 class-sorting preset to Tailwind CSS 4.3.3 (
