gildas-lormeau/SingleFile@biomejs/biome@2.5.3Jul 8, 2026by github-actions[bot]

AI Summary

This is a patch release that addresses various bug fixes and performance improvements. Notable updates include fixes for parser panics in CSS Modules, Svelte store subscription handling, and Vue directive validation, alongside enhancements to Markdown and YAML formatting capabilities.

Key Highlights

  • Fixed parser crashes when encountering unsupported CSS Modules `@value` rules or scoped `@keyframes` at EOF.
  • Resolved false positives for Svelte store subscriptions (`$store`) and `$bindable()` props in the `noUnusedVariables` rule.
  • Enhanced the `noUnsafeOptionalChaining` rule to detect unsafe chains wrapped in TypeScript `as`, `satisfies`, and instantiation expressions.
  • Fixed a deadlock issue in the Biome Language Server when the scanner was enabled.

New Features

  • Added support for sequence mapping in YAML formatting.
  • Improved Markdown formatting compatibility with quotes, thematic breaks, and link definitions.
  • Optimized Markdown parsing to reduce emitted nodes and fold code content lines.
  • Improved embedded range plumbing for general performance.

### Patch Changes

- [#10815](https://github.com/biomejs/biome/pull/10815) [`86613d5`](https://github.com/biomejs/biome/commit/86613d5b01eb965b460ccefbf27f168d87774aaf) Thanks [@WaterWhisperer](https://github.com/WaterWhisperer)! - Fixed a parser panic reported in [#10708](https://github.com/biomejs/biome/issues/10708): Biome now recovers when unsupported CSS Modules `@value` rules or scoped `@keyframes` names end at EOF.

- [#10534](https://github.com/biomejs/biome/pull/10534) [`da9b403`](https://github.com/biomejs/biome/commit/da9b403b6bbacc8d75d56e327a46f4ed0285913e) Thanks [@Mokto](https://github.com/Mokto)! - Fixed [`noUnusedVariables`](https://biomejs.dev/linter/rules/no-unused-variables/) false positives in Svelte files: Svelte store subscriptions (`$store` references in templates now keep the underlying `store` binding from being flagged), and `$bindable()` props that are only written to in the script block (write-only is intentional for bindable props) are no longer reported as unused.

- [#10827](https://github.com/biomejs/biome/pull/10827) [`098ba41`](https://github.com/biomejs/biome/commit/098ba41c99e6efaac8eb182eec258a567bb00123) Thanks [@Aqu1bp](https://github.com/Aqu1bp)! - Fixed [#10698](https://github.com/biomejs/biome/issues/10698): The [`noUnsafeOptionalChaining`](https://biomejs.dev/linter/rules/no-unsafe-optional-chaining/) rule now reports unsafe optional chains wrapped in TypeScript `as`, `satisfies`, type assertion, and instantiation expressions, such as `new (value?.constructor as Constructor)()`.

- [#10773](https://github.com/biomejs/biome/pull/10773) [`3c6513d`](https://github.com/biomejs/biome/commit/3c6513d4e9a82a195785144caa9d96093c3861ff) Thanks [@otkrickey](https://github.com/otkrickey)! - Fixed [#10772](https://github.com/biomejs/biome/issues/10772): [`useVueValidVOn`](https://biomejs.dev/linter/rules/use-vue-valid-v-on/) no longer reports a missing handler for v-on directives using a verb modifier (`.stop` / `.prevent`) without an expression, e.g. `<div @click.stop></div>`. The rule also accepts the arg-less object syntax `<div v-on="$listeners"></div>` instead of reporting a missing event name.

- [#10721](https://github.com/biomejs/biome/pull/10721) [`d83c66b`](https://github.com/biomejs/biome/commit/d83c66b39a820703d94100f8a6502cc6dbad26a1) Thanks [@minseong0324](https://github.com/minseong0324)! - Improved type-aware lint rule inference for built-in globals and indexed function calls. Biome now resolves `Error(...)`, `new Error(...)`, optional `Error#stack`, and calls through indexed function values such as `handlers[0]()` more accurately.

- [#10865](https://github.com/biomejs/biome/pull/10865) [`6450276`](https://github.com/biomejs/biome/commit/6450276764ee4794a0fcb46c139f95b68d892427) Thanks [@ematipico](https://github.com/ematipico)! - Fixed [#10845](https://github.com/biomejs/biome/issues/10845). Biome Language Server no longer goes in deadlock when the scanner is enabled.

- [#10853](https://github.com/biomejs/biome/pull/10853) [`93d8e53`](https://github.com/biomejs/biome/commit/93d8e5352454bccfbd179db03b3155776599c52c) Thanks [@Netail](https://github.com/Netail)! - Fixed [#10840](https://github.com/biomejs/biome/issues/10840): Astro shorthand attribute syntax is now correctly being parsed from embedded nodes.

- [#10820](https://github.com/biomejs/biome/pull/10820) [`bba3092`](https://github.com/biomejs/biome/commit/bba30920715920142e933939f6270feedca933a5) Thanks [@JamBalaya56562](https://github.com/JamBalaya56562)! - Fixed [#10619](https://github.com/biomejs/biome/issues/10619): [`noProcessEnv`](https://biomejs.dev/linter/rules/no-process-env/) now also reports computed (bracket) member access. Previously only dot access was checked, so `process["env"]` and `env["NODE_ENV"]` (where `env` is imported from `node:process`) were missed. Both static and computed accesses are now reported.

- [#10835](https://github.com/biomejs/biome/pull/10835) [`3447b2f`](https://github.com/biomejs/biome/commit/3447b2f5a3c430efc8e917514260af5341c5509d) Thanks [@dyc3](https://github.com/dyc3)! - Fixed [#10824](https://github.com/biomejs/biome/issues/10824): [`useDomQuerySelector`](https://biomejs.dev/linter/rules/use-dom-query-selector/) now supports an `ignore` option for receiver identifiers that should not be reported.

- [#10875](https://github.com/biomejs/biome/pull/10875) [`b12e486`](https://github.com/biomejs/biome/commit/b12e486d0f0b80d02d2208e239190f8756d39d48) Thanks [@dyc3](https://github.com/dyc3)! - Fixed [#10795](https://github.com/biomejs/biome/issues/10795): `--profile-rules` now reports timings for each plugin separately as `plugin/<pluginName>`, matching the naming used by plugin suppressions, instead of aggregating all plugins under a single `plugin/plugin` entry.

- [#10877](https://github.com/biomejs/biome/pull/10877) [`d6bc447`](https://github.com/biomejs/biome/commit/d6bc4473a210758ee49f6cad41bc69587a7cf125) Thanks [@ematipico](https://github.com/ematipico)! - Fixed [biome-zed#164](https://github.com/biomejs/biome-zed/issues/164): Biome no longer inserts stray whitespace when format-on-type runs after closing delimiters such as `)`, `]`, and `}`.

- [#10867](https://github.com/biomejs/biome/pull/10867) [`a21463e`](https://github.com/biomejs/biome/commit/a21463e5f616a2db5035b470cd206ac9da4d9423) Thanks [@dyc3](https://github.com/dyc3)! - Fixed [#10864](https://github.com/biomejs/biome/issues/10864): Biome no longer crashes when checking or linting HTML files with unquoted attribute values such as `<textarea rows=4></textarea>`.
