🔧 Bug Fixes & Patches (6)

Fixed #9463: the "Biome found a configuration file outside of the current working directory" diagnostic now includes the configuration file path and the working directory, giving users actionable information to debug the issue.
Fixed #8959: Fixed TypeScript arrow function formatting when a comment appears after `=>`.
Added the rule `noDrizzleUpdateWithoutWhere` to prevent accidental full-table updates when using Drizzle ORM without a `.where()` clause.
Fixed #9187: Astro frontmatter containing regex literals with quotes (`/'/`, `/"/`) or dashes (`/---/`) no longer causes parse errors.
Fixed #9524: remove extra space before `>` when `bracketSameLine` is true and the self-closing slash is absent in HTML formatter.
Fixed #9238: The HTML parser no longer incorrectly reports `---` inside element content (e.g. `<td>---</td>`) as an "Unexpected value or character" error.

Previously, a pattern like `"./*"` could match before `"./features/*"`, causing resolution failures for packages with overlapping subpath patterns. - [#9515](https://github.com/biomejs/biome/pull/9515) [`f85c069`](https://github.com/biomejs/biome/commit/f85c069acd182382832dbbc116ff28b1dca9d9be) Thanks [@shivamtiwari3](https://github.com/shivamtiwari3)! - Fixed [#9506](https://github.com/biomejs/biome/issues/9506) and [#9479](https://github.com/biomejs/biome/issues/9479): Biome no longer reports false parse errors on `<script type="speculationrules">` and `<script type="application/ld+json">` tags.

Previously, the `vcs.root` setting was ignored and Biome always looked for the ignore file in the workspace directory. - [#9521](https://github.com/biomejs/biome/pull/9521) [`af39936`](https://github.com/biomejs/biome/commit/af3993681b91a8434da0974833249d20ff844bab) Thanks [@ematipico](https://github.com/ematipico)! - Fixed [#9483](https://github.com/biomejs/biome/issues/9483). Now the rule `noRedeclare` doesn't panic when it encounters constructor overloads. - [#9490](https://github.com/biomejs/biome/pull/9490) [`60cf024`](https://github.com/biomejs/biome/commit/60cf0248221f5e3e4eacbbfa29a8b25f2b3c1a79) Thanks [@willfarrell](https://github.com/willfarrell)! - Added support for modern CSS properties, pseudo-classes, and pseudo-elements.

New pseudo-classes: `:active-view-transition-type`, `:has-slotted`, `:target-after`, `:target-before`, `:target-current`. - [#9526](https://github.com/biomejs/biome/pull/9526) [`4d42823`](https://github.com/biomejs/biome/commit/4d42823aa6d71908cd5b52ebae460c8a77388980) Thanks [@ematipico](https://github.com/ematipico)! - Fixed [#9358](https://github.com/biomejs/biome/issues/9358) and [#9375](https://github.com/biomejs/biome/issues/9375). Now attributes that have text expressions such as `class={buttonClass()}` are correctly tracked in Svelte files. - [#9520](https://github.com/biomejs/biome/pull/9520) [`61f53ee`](https://github.com/biomejs/biome/commit/61f53ee073310879d095239312e31628841efb3d) Thanks [@ematipico](https://github.com/ematipico)! - Fixed [#9519](https://github.com/biomejs/biome/issues/9519). Now `noUnusedVariables` doesn't flag variables that are used as `typeof` type. - [#9487](https://github.com/biomejs/biome/pull/9487) [`331dc0d`](https://github.com/biomejs/biome/commit/331dc0d53b9cdde93c3d56956428631ef07df984) Thanks [@mvanhorn](https://github.com/mvanhorn)! - Fixed [#9477](https://github.com/biomejs/biome/issues/9477): `source.fixAll.biome` no longer sorts imports when `source.organizeImports.biome` is disabled in editor settings. The organize imports action is now excluded from the fix-all pass unless explicitly requested. - [#9525](https://github.com/biomejs/biome/pull/9525) [`e7b3b10`](https://github.com/biomejs/biome/commit/e7b3b104590fd13b38a2ab044a297fecbcb49e8c) Thanks [@ViniciusDev26](https://github.com/ViniciusDev26)! - Added the rule [`noDrizzleDeleteWithoutWhere`](https://biomejs.dev/linter/rules/no-drizzle-delete-without-where/) to prevent accidental full-table deletes when using Drizzle ORM without a `.where()` clause. ## What's Changed * fix(formatter/md): fix formatting for MdHardLine by @tidefield in https://github.com/biomejs/biome/pull/9480 * chore(deps): update rust:1.94.0-bookworm docker digest to 6a544e5 by @renovate[bot] in https://github.com/biomejs/biome/pull/9493 * chore(deps): update rust:1.94.0-bullseye docker digest to 9d1864f by @renovate[bot] in https://github.com/biomejs/biome/pull/9494 * chore(deps): update rust crate tracing-subscriber to 0.3.23 by @renovate[bot] in https://github.com/biomejs/biome/pull/9498 * chore(benchmark): upgrade to Debian 13 Trixie, Node.js 24 by @siketyan in https://github.com/biomejs/biome/pull/9499 * fix: missing rule source reference by @Netail in https://github.com/biomejs/biome/pull/9504 * chore: manually import dev dependencies by @ematipico in https://github.com/biomejs/biome/pull/9512 * test: infrastructure for embedded langauges by @ematipico in https://github.com/biomejs/biome/pull/9509 * feat(css): parse scss interpolated selector names by @denbezrukov in https://github.com/biomejs/biome/pull/9486 * feat(css): add support for modern CSS properties, pseudo-classes, and pseudo-elements by @willfarrell in https://github.com/biomejs/biome/pull/9490 * fix(html): skip unsupported <script> types instead of treating as JS (fixes #9506, #9479) by @shivamtiwari3 in https://github.com/biomejs/biome/pull/9515 * fix(semantic): regression in tracking scopes by @ematipico in https://github.com/biomejs/biome/pull/9521 * fix(noUnusedVariables): regression in previous refactor by @ematipico in https://github.com/biomejs/biome/pull/9520 * fix(diagnostic): include config path and CWD in ConfigurationOutsideProject by @mvanhorn in https://github.com/biomejs/biome/pull/9488 * fix(lsp): changes file corruption by @ematipico in https://github.com/biomejs/biome/pull/9528 * fix(embeds): track attributes text expressions by @ematipico in https://github.com/biomejs/biome/pull/9526 * fix(core): idempotence formatting html-ish files by @ematipico in https://github.com/biomejs/biome/pull/9532 * fix(ts/formatter): format comment after => in arrow functions by @mdm317 in https://github.com/biomejs/biome/pull/9527 * feat(lint): add noDrizzleDeleteWithoutWhere and noDrizzleUpdateWithoutWhere rules by @ViniciusDev26 in https://github.com/biomejs/biome/pull/9525 * fix(lsp): filter organizeImports from fixAll code action by @mvanhorn in https://github.com/biomejs/biome/pull/9487 * fix(parser/html): regex literals in frontmatter by @ematipico in https://github.com/biomejs/biome/pull/9531 * fix(core): vcs root resolution by @ematipico in https://github.com/biomejs/biome/pull/9514 * fix(resolver): patterns resolution by @ematipico in https://github.com/biomejs/biome/pull/9462 * feat(css): parse scss interpolation for selectors and declaration names by @denbezrukov in https://github.com/biomejs/biome/pull/9529 * fix(noSubstr): query more nodes by @ematipico in https://github.com/biomejs/biome/pull/9538 * fix(html-formatter): remove extra space before > when bracketSameLine… by @leno23 in https://github.com/biomejs/biome/pull/9535 * fix(html/parser): fence in html files by @ematipico in https://github.com/biomejs/biome/pull/9537 * ci: release by @github-actions[bot] in https://github.com/biomejs/biome/pull/9517 ## New Contributors * @willfarrell made their first contribution in https://github.com/biomejs/biome/pull/9490 * @shivamtiwari3 made their first contribution in https://github.com/biomejs/biome/pull/9515 * @mvanhorn made their first contribution in https://github.com/biomejs/biome/pull/9488 * @ViniciusDev26 made their first contribution in https://github.com/biomejs/biome/pull/9525 * @leno23 made their first contribution in https://github.com/biomejs/biome/pull/9535 **Full Changelog**: https://github.com/biomejs/biome/compare/@biomejs/[email protected]...@biomejs/[email protected]
