Claude Code assist writing code and I review it.

Summary

Fixes #6201

  • /[\\-]/ is now treated as valid because the \\ is an escaped backslash and the trailing - is a literal hyphen.
  • Patterns with 1 or 3+ consecutive backslashes before -] (e.g. /[\-]/, /[\\\-]/) are still reported.

Test Plan

Added failing fixtures for the false positive (/[\\-]/ valid; /[\\\-]/, /[\\\\-]/ invalid).

…alse positive

Two cases that should be valid but currently get flagged:

- /[\\-]/  — `\\` is an escaped backslash, trailing `-` is a literal
  hyphen at the end of the class. The rule mistakes the second `\`
  for an unescaped backslash and reports `\-` as useless.
- /[\\\\-]/ — same pattern with another pair of escaped backslashes,
  ensures the lookback handles even longer chains correctly.

Refs biomejs#6201.
…shes before \`-\`

The closing-bracket lookback in the character-class scanner only checked
that the byte two positions back was a backslash. For input like
\`/[\\\\-]/\` that meant the second \`\\\` of the escape pair was treated
as if it were escaping the trailing \`-\`, producing a false positive
whose safe fix removed both backslashes and broke the regex.

Count the consecutive backslashes that precede the dash: an odd count
means the leading \`\\\` is unescaped and genuinely escaping the dash
(\`/[\\-]/\` and \`/[\\\\\\-]/\` still flag); an even count means they
pair up so the dash stands alone (\`/[\\\\-]/\` and \`/[\\\\\\\\-]/\`
no longer flag).

Fixes biomejs#6201.
…seless

Replace the parity-based count with a strict lookback: only the exact
two-backslash case (`\\-]`, an escape pair followed by a literal dash)
is treated as valid. One, three, four, or more backslashes are all
reported.

Move `/[\\\\-]/` out of the valid fixtures and into the invalid ones
alongside `/[\\\-]/` to match the new policy.
Drop the dead `index < 3` branch and the redundant `index >= 4` guard,
collapsing the nested negation into a single `||`. Move the new
3+-backslash fixtures next to the existing `[\-]` cases.

Walkthrough

This PR fixes a false positive in the noUselessEscapeInRegex lint rule. The issue occurred when a regex character class contained an escaped backslash followed by a hyphen (e.g., /[\\-]/). The rule was incorrectly flagging this as a useless escape when the first backslash actually escapes the second backslash, leaving the hyphen unescaped. The fix refines the character-class scanning logic to properly detect escape pairs, with additional test cases covering both valid and invalid patterns.

[Compare Source](https://github.com/biomejs/biome/compare/@biomejs/biome@2.4.13...@biomejs/biome@2.4.14)

##### Patch Changes

- [#&#8203;9393](biomejs/biome#9393) [`491b171`](biomejs/biome@491b171) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Added the nursery rule [`useTestHooksOnTop`](https://biomejs.dev/linter/rules/use-test-hooks-on-top) in the `test` domain. The rule flags lifecycle hooks (`beforeEach`, `beforeAll`, `afterEach`, `afterAll`) that appear after test cases in the same block, enforcing that hooks are defined before any test case.

- [#&#8203;10157](biomejs/biome#10157) [`eefc5ab`](biomejs/biome@eefc5ab) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;7882](biomejs/biome#7882): The HTML parser will now emit better diagnostics when it encounters a void element with a closing tag, such as `<br></br>`. Previously, the parser would emit multiple diagnostics with conflicting advice. Now it emits a single diagnostic that clearly states that void elements should not have closing tags.

- [#&#8203;10054](biomejs/biome#10054) [`0e9f569`](biomejs/biome@0e9f569) Thanks [@&#8203;minseong0324](https://github.com/minseong0324)! - [`noMisleadingReturnType`](https://biomejs.dev/linter/rules/no-misleading-return-type/) no longer misses widening from concrete object types, class instances, object literals, tuples, functions, and regular expressions to `: object`.

  A function annotated `: object` returning an object literal:

  ```ts
  function f(): object {
    return { retry: true };
  }
  ```

- [#&#8203;10116](biomejs/biome#10116) [`53269eb`](biomejs/biome@53269eb) Thanks [@&#8203;jiwon79](https://github.com/jiwon79)! - Fixed [#&#8203;6201](biomejs/biome#6201): [`noUselessEscapeInRegex`](https://biomejs.dev/linter/rules/no-useless-escape-in-regex/) no longer flags an escaped backslash followed by `-` as a useless escape. Patterns like `/[\\-]/` are now considered valid because the second `\` is the escaped backslash, not an unnecessary escape of the trailing dash.

- [#&#8203;10092](biomejs/biome#10092) [`33d8543`](biomejs/biome@33d8543) Thanks [@&#8203;Conaclos](https://github.com/Conaclos)! - Fixed [#&#8203;9097](biomejs/biome#9097): [`organizeImports`](https://biomejs.dev/assist/actions/organize-imports/) no longer adds a blank line between a never-matched group and a matched group.

  Given the following `organizeImports` options:

  ```json
  {
    "groups": [":NODE:", ":BLANK_LINE:", ":PACKAGE:", ":BLANK_LINE:", ":PATH:"]
  }
  ```

  The following code...

  ```js
  // Comment
  import "package";
  import "./file.js";
  ```

  ...was organized as:

  ```diff
  +
    // Comment
    import "package";
  +
    import "./file.js";
  ```

  A blank line was added even though the group ':NODE:' doesn't match any imports here.
  `:BLANK_LINE:` between never-matched groups and matched groups are now ignored.
  The code is now organized as:

  ```diff
    // Comment
    import "package";
  +
    import "./file.js";
  ```

- [#&#8203;10138](biomejs/biome#10138) [`a10b6c1`](biomejs/biome@a10b6c1) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed Vue `v-for` handling for [`noUndeclaredVariables`](https://biomejs.dev/linter/rules/no-undeclared-variables/) and [`noUnusedVariables`](https://biomejs.dev/linter/rules/no-unused-variables/). Biome now recognizes variables declared by `v-for` directives and references to iterated values in Vue templates.

- [#&#8203;10115](biomejs/biome#10115) [`d428d76`](biomejs/biome@d428d76) Thanks [@&#8203;minseong0324](https://github.com/minseong0324)! - [`noMisleadingReturnType`](https://biomejs.dev/linter/rules/no-misleading-return-type/) no longer reports false positives when a union return type's `boolean` variant is covered by both `true` and `false` returns.

- [#&#8203;9922](biomejs/biome#9922) [`7acf1e0`](biomejs/biome@7acf1e0) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Added the new nursery rule [`noReactStringRefs`](https://biomejs.dev/linter/rules/no-react-string-refs/), which disallows legacy React string refs such as `ref="hello"` and `this.refs.hello`.

  Biome also reports template-literal refs such as ``ref={`hello`}``, so React code can consistently migrate to callback refs, `createRef()`, or `useRef()`.

- [#&#8203;10010](biomejs/biome#10010) [`f3e76ab`](biomejs/biome@f3e76ab) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed a bug in the LSP file watcher registration so Biome now watches `.biome.json` and `.biome.jsonc` configuration files and reloads workspace settings when they change.

- [#&#8203;10176](biomejs/biome#10176) [`8a40ef8`](biomejs/biome@8a40ef8) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;10011](biomejs/biome#10011): The [`noThisInStatic`](https://biomejs.dev/linter/rules/no-this-in-static/) rule no longer reports `this` when it is used as the constructor target in `new this(...)`, which is required for inherited static factory methods.

- [#&#8203;10163](biomejs/biome#10163) [`6867e96`](biomejs/biome@6867e96) Thanks [@&#8203;jiwon79](https://github.com/jiwon79)! - Fixed [#&#8203;9884](biomejs/biome#9884): The [`useSortedAttributes`](https://biomejs.dev/assist/actions/use-sorted-attributes/) auto-fix no longer corrupts source code when both an outer JSX element and a nested JSX-valued attribute have unsorted attributes in the same pass. Multiple unsorted groups separated by spread or shorthand attributes within the same JSX element are now reported as a single diagnostic.

- [#&#8203;10079](biomejs/biome#10079) [`d29dd19`](biomejs/biome@d29dd19) Thanks [@&#8203;Damix48](https://github.com/Damix48)! - Fixed false positive in `noAssignInExpressions` for Svelte `{@&#8203;const}` blocks. Assignments in `{@&#8203;const name = value}` are now correctly recognized as declarations rather than accidental assignments in expressions.

- [#&#8203;10080](biomejs/biome#10080) [`5d8fdac`](biomejs/biome@5d8fdac) Thanks [@&#8203;Damix48](https://github.com/Damix48)! - Fixed parsing of closing parentheses in Svelte `{#each}` block key expressions. Biome now correctly parses method calls and other parenthesised expressions used as keys.

  For example, the following snippets are now parsed correctly:

  ```svelte
  {#each numbers as number, index (number.toString())}
    <p>{number}</p>
  {/each}

  {#each numbers as number (key(number))}
    <p>{number}</p>
  {/each}
  ```

- [#&#8203;10140](biomejs/biome#10140) [`e7024b9`](biomejs/biome@e7024b9) Thanks [@&#8203;solithcy](https://github.com/solithcy)! - Fixed [#&#8203;10135](biomejs/biome#10135): Biome no longer crashes on missing Svelte template expressions.

  The following code snippet longer panics:

  ```svelte
  {#if }
   <p>^ this would previously crash</p>
  {/if}
  {@&#8203;const }
  <p>    ^ this would also crash</p>
  ```

- [#&#8203;10111](biomejs/biome#10111) [`7818009`](biomejs/biome@7818009) Thanks [@&#8203;jiwon79](https://github.com/jiwon79)! - Fixed [#&#8203;9997](biomejs/biome#9997): [`noDuplicateSelectors`](https://biomejs.dev/linter/rules/no-duplicate-selectors/) no longer reports false positives for selectors inside `@scope` queries. Biome now treats `@scope` as a separate at-rule context, like `@media`, `@supports`, `@container`, and `@starting-style`.

  The following snippet is no longer flagged as a duplicate:

  ```css
  .Example {
    padding: 0;
  }

  @&#8203;scope (.theme-dark) {
    .Example {
      color: white;
    }
  }
  ```

- [#&#8203;9926](biomejs/biome#9926) [`d62b331`](biomejs/biome@d62b331) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Added the nursery lint rule [`useMathMinMax`](https://biomejs.dev/linter/rules/use-math-min-max/), which prefers `Math.min()` and `Math.max()` over equivalent ternary comparisons.

  For example, this code:

  ```js
  const min = a < b ? a : b;
  ```

  is much more readable when rewritten as:

  ```js
  const min = Math.min(a, b);
  ```

- [#&#8203;10115](biomejs/biome#10115) [`d428d76`](biomejs/biome@d428d76) Thanks [@&#8203;minseong0324](https://github.com/minseong0324)! - [`useExhaustiveSwitchCases`](https://biomejs.dev/linter/rules/use-exhaustive-switch-cases/) now flags missing `true`/`false` cases for `boolean` discriminants, including when `boolean` is a union variant.

- [#&#8203;10125](biomejs/biome#10125) [`a55a0b6`](biomejs/biome@a55a0b6) Thanks [@&#8203;bmish](https://github.com/bmish)! - Fixed a resolver bug where packages that define a typed entry point through `package.json`'s `main` field but omit `types` were ignored during type-aware resolution. Type-aware rules such as [`noFloatingPromises`](https://biomejs.dev/linter/rules/no-floating-promises/) can now inspect imports from those packages.

- [#&#8203;10117](biomejs/biome#10117) [`895e809`](biomejs/biome@895e809) Thanks [@&#8203;denizdogan](https://github.com/denizdogan)! - Added support for the `corner-shape` family of CSS properties and the `superellipse()`/`squircle()` value functions, so [`noUnknownProperty`](https://biomejs.dev/linter/rules/no-unknown-property/) and [`noUnknownFunction`](https://biomejs.dev/linter/rules/no-unknown-function/) no longer flag them as unknown.

  New known properties: `corner-shape`, `corner-block-end-shape`, `corner-block-start-shape`, `corner-bottom-left-shape`, `corner-bottom-right-shape`, `corner-bottom-shape`, `corner-end-end-shape`, `corner-end-start-shape`, `corner-inline-end-shape`, `corner-inline-start-shape`, `corner-left-shape`, `corner-right-shape`, `corner-start-end-shape`, `corner-start-start-shape`, `corner-top-left-shape`, `corner-top-right-shape`, `corner-top-shape`.

  New known value functions: `superellipse()`, `squircle()`.

- [#&#8203;8620](biomejs/biome#8620) [`8df8f73`](biomejs/biome@8df8f73) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;8062](biomejs/biome#8062): Added support for parsing Vue `v-for` directives more accurately.

- [#&#8203;10191](biomejs/biome#10191) [`aa055cd`](biomejs/biome@aa055cd) Thanks [@&#8203;guney](https://github.com/guney)! - Now the rule [`noStaticElementInteractions`](https://biomejs.dev/linter/rules/no-static-element-interactions/) doesn't trigger custom elements.

- [#&#8203;9757](biomejs/biome#9757) [`2c62594`](biomejs/biome@2c62594) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;9099](biomejs/biome#9099): the HTML formatter collapsing non-text children (inline elements, Svelte expressions, comments) onto a single line when the source had them on separate lines. Biome now preserves the user's intended line breaks for exclusively non-text children.

  For example, the following Svelte snippet is now preserved instead of being collapsed to `<div>{name}<!-- comment --></div>`:

  ```svelte
  <div>
    {name}<!-- comment -->
  </div>
  ```

  Similarly, HTML elements like `<span>` inside a `<div>` are now preserved when written on their own line:

  ```html
  <div>
    <span>text</span>
  </div>
  ```

- [#&#8203;10105](biomejs/biome#10105) [`e7c1a6d`](biomejs/biome@e7c1a6d) Thanks [@&#8203;jiwon79](https://github.com/jiwon79)! - Fixed [#&#8203;10039](biomejs/biome#10039): [`useReadonlyClassProperties`](https://biomejs.dev/linter/rules/use-readonly-class-properties/) now detects unreassigned private members in class expressions and export default classes, not only in class declarations.

  The following patterns are now correctly flagged:

  ```ts
  const AnonClass = class {
    #prop = 123;
    constructor() {
      console.log(this.#prop);
    }
  };

  export default class {
    #prop = 123;
    constructor() {
      console.log(this.#prop);
    }
  }
  ```

- [#&#8203;10141](biomejs/biome#10141) [`46a77d0`](biomejs/biome@46a77d0) Thanks [@&#8203;minseong0324](https://github.com/minseong0324)! - Improved [`noUnnecessaryConditions`](https://biomejs.dev/linter/rules/no-unnecessary-conditions/) to detect conditions that are always truthy because they check built-in global class instances such as `Date`, `Map`, `Set`, `WeakMap`, and `Error`.

- [#&#8203;10178](biomejs/biome#10178) [`7b05a89`](biomejs/biome@7b05a89) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;10177](biomejs/biome#10177): The HTML parser no longer reports lowercase `html` or `doctype` text as invalid after void elements such as `<br>`.

- [#&#8203;10155](biomejs/biome#10155) [`0d4595d`](biomejs/biome@0d4595d) Thanks [@&#8203;jiwon79](https://github.com/jiwon79)! - Fixed [#&#8203;10045](biomejs/biome#10045): the CSS formatter no longer compounds indentation inside nested functional pseudo-classes such as `:not(:where(...))`, `:is(:where(...))`, and similar combinations. The same fix also removes one level of unnecessary indentation that was added inside any pseudo-class function whose argument list wrapped onto multiple lines, including `:nth-child(... of ...)`, `::part(...)`, and `:active-view-transition-type(...)`.
  The following snippet is now correctly formatted, matching Prettier.

  ```css
  input:not(
    :where(
      [type="submit"],
      [type="checkbox"],
      [type="radio"],
      [type="button"],
      [type="reset"]
    )
  ) {
    inline-size: 100%;
  }
  ```

- [#&#8203;10112](biomejs/biome#10112) [`6f0251e`](biomejs/biome@6f0251e) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;10110](biomejs/biome#10110): Biome's parser now accepts surrogate code points in JavaScript string `\u{...}` escapes.

- [#&#8203;10141](biomejs/biome#10141) [`46a77d0`](biomejs/biome@46a77d0) Thanks [@&#8203;minseong0324](https://github.com/minseong0324)! - Improved [`noMisleadingReturnType`](https://biomejs.dev/linter/rules/no-misleading-return-type/) to detect `object` return annotations that hide built-in global class instances such as `Date`, `Map`, `Set`, `WeakMap`, and `Error`.

- [#&#8203;10083](biomejs/biome#10083) [`4a664c1`](biomejs/biome@4a664c1) Thanks [@&#8203;ematipico](https://github.com/ematipico)! - Added two new options to [`noShadow`](https://biomejs.dev/linter/rules/no-shadow/), both defaulting to `true` to match typescript-eslint's behavior.

  Fixed [#&#8203;9482](biomejs/biome#9482): Added `ignoreFunctionTypeParameterNameValueShadow` option. When enabled, parameter names inside function type annotations (e.g. `(options: unknown) => void`) are not flagged as shadowing outer variables.

  Fixed [#&#8203;7812](biomejs/biome#7812): Added `ignoreTypeValueShadow` option. When enabled, a value binding that shares its name with a type-only declaration (type alias or interface) is not flagged, since types and values occupy separate namespaces in TypeScript.

- [#&#8203;9286](biomejs/biome#9286) [`52695cf`](biomejs/biome@52695cf) Thanks [@&#8203;Hugo-Polloli](https://github.com/Hugo-Polloli)! - Fixed [#&#8203;6316](biomejs/biome#6316): Biome now resolves Svelte `$store` references to the underlying `store` binding in semantic analysis, preventing false `noUndeclaredVariables` diagnostics when the store is declared.

- [#&#8203;10188](biomejs/biome#10188) [`ae659dd`](biomejs/biome@ae659dd) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Added a new nursery rule [`noExcessiveNestedCallbacks`](https://biomejs.dev/linter/rules/no-excessive-nested-callbacks/), which disallows callbacks nested deeper than the configured maximum.

- [#&#8203;9757](biomejs/biome#9757) [`2c62594`](biomejs/biome@2c62594) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;9450](biomejs/biome#9450): the HTML formatter now correctly preserves multiline formatting for nested `<template>` elements (e.g. `<template #body>`) when the source has children on separate lines. Previously, the children were collapsed onto a single line.

##### Patch Changes

- [#&#8203;9393](biomejs/biome#9393) [`491b171`](biomejs/biome@491b171) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Added the nursery rule [`useTestHooksOnTop`](https://biomejs.dev/linter/rules/use-test-hooks-on-top) in the `test` domain. The rule flags lifecycle hooks (`beforeEach`, `beforeAll`, `afterEach`, `afterAll`) that appear after test cases in the same block, enforcing that hooks are defined before any test case.

- [#&#8203;10157](biomejs/biome#10157) [`eefc5ab`](biomejs/biome@eefc5ab) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;7882](biomejs/biome#7882): The HTML parser will now emit better diagnostics when it encounters a void element with a closing tag, such as `<br></br>`. Previously, the parser would emit multiple diagnostics with conflicting advice. Now it emits a single diagnostic that clearly states that void elements should not have closing tags.

- [#&#8203;10054](biomejs/biome#10054) [`0e9f569`](biomejs/biome@0e9f569) Thanks [@&#8203;minseong0324](https://github.com/minseong0324)! - [`noMisleadingReturnType`](https://biomejs.dev/linter/rules/no-misleading-return-type/) no longer misses widening from concrete object types, class instances, object literals, tuples, functions, and regular expressions to `: object`.

  A function annotated `: object` returning an object literal:

  ```ts
  function f(): object {
    return { retry: true };
  }
  ```

- [#&#8203;10116](biomejs/biome#10116) [`53269eb`](biomejs/biome@53269eb) Thanks [@&#8203;jiwon79](https://github.com/jiwon79)! - Fixed [#&#8203;6201](biomejs/biome#6201): [`noUselessEscapeInRegex`](https://biomejs.dev/linter/rules/no-useless-escape-in-regex/) no longer flags an escaped backslash followed by `-` as a useless escape. Patterns like `/[\\-]/` are now considered valid because the second `\` is the escaped backslash, not an unnecessary escape of the trailing dash.

- [#&#8203;10092](biomejs/biome#10092) [`33d8543`](biomejs/biome@33d8543) Thanks [@&#8203;Conaclos](https://github.com/Conaclos)! - Fixed [#&#8203;9097](biomejs/biome#9097): [`organizeImports`](https://biomejs.dev/assist/actions/organize-imports/) no longer adds a blank line between a never-matched group and a matched group.

  Given the following `organizeImports` options:

  ```json
  {
    "groups": [":NODE:", ":BLANK_LINE:", ":PACKAGE:", ":BLANK_LINE:", ":PATH:"]
  }
  ```

  The following code...

  ```js
  // Comment
  import "package";
  import "./file.js";
  ```

  ...was organized as:

  ```diff
  +
    // Comment
    import "package";
  +
    import "./file.js";
  ```

  A blank line was added even though the group ':NODE:' doesn't match any imports here.
  `:BLANK_LINE:` between never-matched groups and matched groups are now ignored.
  The code is now organized as:

  ```diff
    // Comment
    import "package";
  +
    import "./file.js";
  ```

- [#&#8203;10138](biomejs/biome#10138) [`a10b6c1`](biomejs/biome@a10b6c1) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed Vue `v-for` handling for [`noUndeclaredVariables`](https://biomejs.dev/linter/rules/no-undeclared-variables/) and [`noUnusedVariables`](https://biomejs.dev/linter/rules/no-unused-variables/). Biome now recognizes variables declared by `v-for` directives and references to iterated values in Vue templates.

- [#&#8203;10115](biomejs/biome#10115) [`d428d76`](biomejs/biome@d428d76) Thanks [@&#8203;minseong0324](https://github.com/minseong0324)! - [`noMisleadingReturnType`](https://biomejs.dev/linter/rules/no-misleading-return-type/) no longer reports false positives when a union return type's `boolean` variant is covered by both `true` and `false` returns.

- [#&#8203;9922](biomejs/biome#9922) [`7acf1e0`](biomejs/biome@7acf1e0) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Added the new nursery rule [`noReactStringRefs`](https://biomejs.dev/linter/rules/no-react-string-refs/), which disallows legacy React string refs such as `ref="hello"` and `this.refs.hello`.

  Biome also reports template-literal refs such as ``ref={`hello`}``, so React code can consistently migrate to callback refs, `createRef()`, or `useRef()`.

- [#&#8203;10010](biomejs/biome#10010) [`f3e76ab`](biomejs/biome@f3e76ab) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed a bug in the LSP file watcher registration so Biome now watches `.biome.json` and `.biome.jsonc` configuration files and reloads workspace settings when they change.

- [#&#8203;10176](biomejs/biome#10176) [`8a40ef8`](biomejs/biome@8a40ef8) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;10011](biomejs/biome#10011): The [`noThisInStatic`](https://biomejs.dev/linter/rules/no-this-in-static/) rule no longer reports `this` when it is used as the constructor target in `new this(...)`, which is required for inherited static factory methods.

- [#&#8203;10163](biomejs/biome#10163) [`6867e96`](biomejs/biome@6867e96) Thanks [@&#8203;jiwon79](https://github.com/jiwon79)! - Fixed [#&#8203;9884](biomejs/biome#9884): The [`useSortedAttributes`](https://biomejs.dev/assist/actions/use-sorted-attributes/) auto-fix no longer corrupts source code when both an outer JSX element and a nested JSX-valued attribute have unsorted attributes in the same pass. Multiple unsorted groups separated by spread or shorthand attributes within the same JSX element are now reported as a single diagnostic.

- [#&#8203;10079](biomejs/biome#10079) [`d29dd19`](biomejs/biome@d29dd19) Thanks [@&#8203;Damix48](https://github.com/Damix48)! - Fixed false positive in `noAssignInExpressions` for Svelte `{@&#8203;const}` blocks. Assignments in `{@&#8203;const name = value}` are now correctly recognized as declarations rather than accidental assignments in expressions.

- [#&#8203;10080](biomejs/biome#10080) [`5d8fdac`](biomejs/biome@5d8fdac) Thanks [@&#8203;Damix48](https://github.com/Damix48)! - Fixed parsing of closing parentheses in Svelte `{#each}` block key expressions. Biome now correctly parses method calls and other parenthesised expressions used as keys.

  For example, the following snippets are now parsed correctly:

  ```svelte
  {#each numbers as number, index (number.toString())}
    <p>{number}</p>
  {/each}

  {#each numbers as number (key(number))}
    <p>{number}</p>
  {/each}
  ```

- [#&#8203;10140](biomejs/biome#10140) [`e7024b9`](biomejs/biome@e7024b9) Thanks [@&#8203;solithcy](https://github.com/solithcy)! - Fixed [#&#8203;10135](biomejs/biome#10135): Biome no longer crashes on missing Svelte template expressions.

  The following code snippet longer panics:

  ```svelte
  {#if }
   <p>^ this would previously crash</p>
  {/if}
  {@&#8203;const }
  <p>    ^ this would also crash</p>
  ```

- [#&#8203;10111](biomejs/biome#10111) [`7818009`](biomejs/biome@7818009) Thanks [@&#8203;jiwon79](https://github.com/jiwon79)! - Fixed [#&#8203;9997](biomejs/biome#9997): [`noDuplicateSelectors`](https://biomejs.dev/linter/rules/no-duplicate-selectors/) no longer reports false positives for selectors inside `@scope` queries. Biome now treats `@scope` as a separate at-rule context, like `@media`, `@supports`, `@container`, and `@starting-style`.

  The following snippet is no longer flagged as a duplicate:

  ```css
  .Example {
    padding: 0;
  }

  @&#8203;scope (.theme-dark) {
    .Example {
      color: white;
    }
  }
  ```

- [#&#8203;9926](biomejs/biome#9926) [`d62b331`](biomejs/biome@d62b331) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Added the nursery lint rule [`useMathMinMax`](https://biomejs.dev/linter/rules/use-math-min-max/), which prefers `Math.min()` and `Math.max()` over equivalent ternary comparisons.

  For example, this code:

  ```js
  const min = a < b ? a : b;
  ```

  is much more readable when rewritten as:

  ```js
  const min = Math.min(a, b);
  ```

- [#&#8203;10115](biomejs/biome#10115) [`d428d76`](biomejs/biome@d428d76) Thanks [@&#8203;minseong0324](https://github.com/minseong0324)! - [`useExhaustiveSwitchCases`](https://biomejs.dev/linter/rules/use-exhaustive-switch-cases/) now flags missing `true`/`false` cases for `boolean` discriminants, including when `boolean` is a union variant.

- [#&#8203;10125](biomejs/biome#10125) [`a55a0b6`](biomejs/biome@a55a0b6) Thanks [@&#8203;bmish](https://github.com/bmish)! - Fixed a resolver bug where packages that define a typed entry point through `package.json`'s `main` field but omit `types` were ignored during type-aware resolution. Type-aware rules such as [`noFloatingPromises`](https://biomejs.dev/linter/rules/no-floating-promises/) can now inspect imports from those packages.

- [#&#8203;10117](biomejs/biome#10117) [`895e809`](biomejs/biome@895e809) Thanks [@&#8203;denizdogan](https://github.com/denizdogan)! - Added support for the `corner-shape` family of CSS properties and the `superellipse()`/`squircle()` value functions, so [`noUnknownProperty`](https://biomejs.dev/linter/rules/no-unknown-property/) and [`noUnknownFunction`](https://biomejs.dev/linter/rules/no-unknown-function/) no longer flag them as unknown.

  New known properties: `corner-shape`, `corner-block-end-shape`, `corner-block-start-shape`, `corner-bottom-left-shape`, `corner-bottom-right-shape`, `corner-bottom-shape`, `corner-end-end-shape`, `corner-end-start-shape`, `corner-inline-end-shape`, `corner-inline-start-shape`, `corner-left-shape`, `corner-right-shape`, `corner-start-end-shape`, `corner-start-start-shape`, `corner-top-left-shape`, `corner-top-right-shape`, `corner-top-shape`.

  New known value functions: `superellipse()`, `squircle()`.

- [#&#8203;8620](biomejs/biome#8620) [`8df8f73`](biomejs/biome@8df8f73) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;8062](biomejs/biome#8062): Added support for parsing Vue `v-for` directives more accurately.

- [#&#8203;10191](biomejs/biome#10191) [`aa055cd`](biomejs/biome@aa055cd) Thanks [@&#8203;guney](https://github.com/guney)! - Now the rule [`noStaticElementInteractions`](https://biomejs.dev/linter/rules/no-static-element-interactions/) doesn't trigger custom elements.

- [#&#8203;9757](biomejs/biome#9757) [`2c62594`](biomejs/biome@2c62594) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;9099](biomejs/biome#9099): the HTML formatter collapsing non-text children (inline elements, Svelte expressions, comments) onto a single line when the source had them on separate lines. Biome now preserves the user's intended line breaks for exclusively non-text children.

  For example, the following Svelte snippet is now preserved instead of being collapsed to `<div>{name}<!-- comment --></div>`:

  ```svelte
  <div>
    {name}<!-- comment -->
  </div>
  ```

  Similarly, HTML elements like `<span>` inside a `<div>` are now preserved when written on their own line:

  ```html
  <div>
    <span>text</span>
  </div>
  ```

- [#&#8203;10105](biomejs/biome#10105) [`e7c1a6d`](biomejs/biome@e7c1a6d) Thanks [@&#8203;jiwon79](https://github.com/jiwon79)! - Fixed [#&#8203;10039](biomejs/biome#10039): [`useReadonlyClassProperties`](https://biomejs.dev/linter/rules/use-readonly-class-properties/) now detects unreassigned private members in class expressions and export default classes, not only in class declarations.

  The following patterns are now correctly flagged:

  ```ts
  const AnonClass = class {
    #prop = 123;
    constructor() {
      console.log(this.#prop);
    }
  };

  export default class {
    #prop = 123;
    constructor() {
      console.log(this.#prop);
    }
  }
  ```

- [#&#8203;10141](biomejs/biome#10141) [`46a77d0`](biomejs/biome@46a77d0) Thanks [@&#8203;minseong0324](https://github.com/minseong0324)! - Improved [`noUnnecessaryConditions`](https://biomejs.dev/linter/rules/no-unnecessary-conditions/) to detect conditions that are always truthy because they check built-in global class instances such as `Date`, `Map`, `Set`, `WeakMap`, and `Error`.

- [#&#8203;10178](biomejs/biome#10178) [`7b05a89`](biomejs/biome@7b05a89) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;10177](biomejs/biome#10177): The HTML parser no longer reports lowercase `html` or `doctype` text as invalid after void elements such as `<br>`.

- [#&#8203;10155](biomejs/biome#10155) [`0d4595d`](biomejs/biome@0d4595d) Thanks [@&#8203;jiwon79](https://github.com/jiwon79)! - Fixed [#&#8203;10045](biomejs/biome#10045): the CSS formatter no longer compounds indentation inside nested functional pseudo-classes such as `:not(:where(...))`, `:is(:where(...))`, and similar combinations. The same fix also removes one level of unnecessary indentation that was added inside any pseudo-class function whose argument list wrapped onto multiple lines, including `:nth-child(... of ...)`, `::part(...)`, and `:active-view-transition-type(...)`.
  The following snippet is now correctly formatted, matching Prettier.

  ```css
  input:not(
    :where(
      [type="submit"],
      [type="checkbox"],
      [type="radio"],
      [type="button"],
      [type="reset"]
    )
  ) {
    inline-size: 100%;
  }
  ```

- [#&#8203;10112](biomejs/biome#10112) [`6f0251e`](biomejs/biome@6f0251e) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;10110](biomejs/biome#10110): Biome's parser now accepts surrogate code points in JavaScript string `\u{...}` escapes.

- [#&#8203;10141](biomejs/biome#10141) [`46a77d0`](biomejs/biome@46a77d0) Thanks [@&#8203;minseong0324](https://github.com/minseong0324)! - Improved [`noMisleadingReturnType`](https://biomejs.dev/linter/rules/no-misleading-return-type/) to detect `object` return annotations that hide built-in global class instances such as `Date`, `Map`, `Set`, `WeakMap`, and `Error`.

- [#&#8203;10083](biomejs/biome#10083) [`4a664c1`](biomejs/biome@4a664c1) Thanks [@&#8203;ematipico](https://github.com/ematipico)! - Added two new options to [`noShadow`](https://biomejs.dev/linter/rules/no-shadow/), both defaulting to `true` to match typescript-eslint's behavior.

  Fixed [#&#8203;9482](biomejs/biome#9482): Added `ignoreFunctionTypeParameterNameValueShadow` option. When enabled, parameter names inside function type annotations (e.g. `(options: unknown) => void`) are not flagged as shadowing outer variables.

  Fixed [#&#8203;7812](biomejs/biome#7812): Added `ignoreTypeValueShadow` option. When enabled, a value binding that shares its name with a type-only declaration (type alias or interface) is not flagged, since types and values occupy separate namespaces in TypeScript.

- [#&#8203;9286](biomejs/biome#9286) [`52695cf`](biomejs/biome@52695cf) Thanks [@&#8203;Hugo-Polloli](https://github.com/Hugo-Polloli)! - Fixed [#&#8203;6316](biomejs/biome#6316): Biome now resolves Svelte `$store` references to the underlying `store` binding in semantic analysis, preventing false `noUndeclaredVariables` diagnostics when the store is declared.

- [#&#8203;10188](biomejs/biome#10188) [`ae659dd`](biomejs/biome@ae659dd) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Added a new nursery rule [`noExcessiveNestedCallbacks`](https://biomejs.dev/linter/rules/no-excessive-nested-callbacks/), which disallows callbacks nested deeper than the configured maximum.

- [#&#8203;9757](biomejs/biome#9757) [`2c62594`](biomejs/biome@2c62594) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;9450](biomejs/biome#9450): the HTML formatter now correctly preserves multiline formatting for nested `<template>` elements (e.g. `<template #body>`) when the source has children on separate lines. Previously, the children were collapsed onto a single line.

  ```diff
   <template>
     <UModal>
  -    <template #body> <p>content</p> </template>
  +    <template #body>
  +      <p>content</p>

   </template>
  ```

- [#&#8203;10118](biomejs/biome#10118) [`c6edcb4`](biomejs/biome@c6edcb4) Thanks [@&#8203;Netail](https://github.com/Netail)! - Fixed [#&#8203;10024](biomejs/biome#10024): `biome migrate eslint` correctly migrates `eslint` rules that belong to multiple Biome rules.

    "groups": [":NODE:", ":BLANK_LINE:", ":PACKAGE:", ":BLANK_LINE:", ":PATH:"]
  }
  ```

  The following code...

  ```js
  // Comment
  import "package";
  import "./file.js";
  ```

  ...was organized as:

  ```diff
  +
    // Comment
    import "package";
  +
    import "./file.js";
  ```

  A blank line was added even though the group ':NODE:' doesn't match any imports here.
  `:BLANK_LINE:` between never-matched groups and matched groups are now ignored.
  The code is now organized as:

  ```diff
    // Comment
    import "package";
  +
    import "./file.js";
  ```

- [#&#8203;10138](biomejs/biome#10138) [`a10b6c1`](biomejs/biome@a10b6c1) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed Vue `v-for` handling for [`noUndeclaredVariables`](https://biomejs.dev/linter/rules/no-undeclared-variables/) and [`noUnusedVariables`](https://biomejs.dev/linter/rules/no-unused-variables/). Biome now recognizes variables declared by `v-for` directives and references to iterated values in Vue templates.

- [#&#8203;10115](biomejs/biome#10115) [`d428d76`](biomejs/biome@d428d76) Thanks [@&#8203;minseong0324](https://github.com/minseong0324)! - [`noMisleadingReturnType`](https://biomejs.dev/linter/rules/no-misleading-return-type/) no longer reports false positives when a union return type's `boolean` variant is covered by both `true` and `false` returns.

- [#&#8203;9922](biomejs/biome#9922) [`7acf1e0`](biomejs/biome@7acf1e0) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Added the new nursery rule [`noReactStringRefs`](https://biomejs.dev/linter/rules/no-react-string-refs/), which disallows legacy React string refs such as `ref="hello"` and `this.refs.hello`.

  Biome also reports template-literal refs such as ``ref={`hello`}``, so React code can consistently migrate to callback refs, `createRef()`, or `useRef()`.

- [#&#8203;10010](biomejs/biome#10010) [`f3e76ab`](biomejs/biome@f3e76ab) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed a bug in the LSP file watcher registration so Biome now watches `.biome.json` and `.biome.jsonc` configuration files and reloads workspace settings when they change.

- [#&#8203;10176](biomejs/biome#10176) [`8a40ef8`](biomejs/biome@8a40ef8) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;10011](biomejs/biome#10011): The [`noThisInStatic`](https://biomejs.dev/linter/rules/no-this-in-static/) rule no longer reports `this` when it is used as the constructor target in `new this(...)`, which is required for inherited static factory methods.

- [#&#8203;10163](biomejs/biome#10163) [`6867e96`](biomejs/biome@6867e96) Thanks [@&#8203;jiwon79](https://github.com/jiwon79)! - Fixed [#&#8203;9884](biomejs/biome#9884): The [`useSortedAttributes`](https://biomejs.dev/assist/actions/use-sorted-attributes/) auto-fix no longer corrupts source code when both an outer JSX element and a nested JSX-valued attribute have unsorted attributes in the same pass. Multiple unsorted groups separated by spread or shorthand attributes within the same JSX element are now reported as a single diagnostic.

- [#&#8203;10079](biomejs/biome#10079) [`d29dd19`](biomejs/biome@d29dd19) Thanks [@&#8203;Damix48](https://github.com/Damix48)! - Fixed false positive in `noAssignInExpressions` for Svelte `{@&#8203;const}` blocks. Assignments in `{@&#8203;const name = value}` are now correctly recognized as declarations rather than accidental assignments in expressions.

- [#&#8203;10080](biomejs/biome#10080) [`5d8fdac`](biomejs/biome@5d8fdac) Thanks [@&#8203;Damix48](https://github.com/Damix48)! - Fixed parsing of closing parentheses in Svelte `{#each}` block key expressions. Biome now correctly parses method calls and other parenthesised expressions used as keys.

  For example, the following snippets are now parsed correctly:

  ```svelte
  {#each numbers as number, index (number.toString())}
    <p>{number}</p>
  {/each}

  {#each numbers as number (key(number))}
    <p>{number}</p>
  {/each}
  ```

- [#&#8203;10140](biomejs/biome#10140) [`e7024b9`](biomejs/biome@e7024b9) Thanks [@&#8203;solithcy](https://github.com/solithcy)! - Fixed [#&#8203;10135](biomejs/biome#10135): Biome no longer crashes on missing Svelte template expressions.

  The following code snippet longer panics:

  ```svelte
  {#if }
   <p>^ this would previously crash</p>
  {/if}
  {@&#8203;const }
  <p>    ^ this would also crash</p>
  ```

- [#&#8203;10111](biomejs/biome#10111) [`7818009`](biomejs/biome@7818009) Thanks [@&#8203;jiwon79](https://github.com/jiwon79)! - Fixed [#&#8203;9997](biomejs/biome#9997): [`noDuplicateSelectors`](https://biomejs.dev/linter/rules/no-duplicate-selectors/) no longer reports false positives for selectors inside `@scope` queries. Biome now treats `@scope` as a separate at-rule context, like `@media`, `@supports`, `@container`, and `@starting-style`.

  The following snippet is no longer flagged as a duplicate:

  ```css
  .Example {
    padding: 0;
  }

  @&#8203;scope (.theme-dark) {
    .Example {
      color: white;
    }
  }
  ```

- [#&#8203;9926](biomejs/biome#9926) [`d62b331`](biomejs/biome@d62b331) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Added the nursery lint rule [`useMathMinMax`](https://biomejs.dev/linter/rules/use-math-min-max/), which prefers `Math.min()` and `Math.max()` over equivalent ternary comparisons.

  For example, this code:

  ```js
  const min = a < b ? a : b;
  ```

  is much more readable when rewritten as:

  ```js
  const min = Math.min(a, b);
  ```

- [#&#8203;10115](biomejs/biome#10115) [`d428d76`](biomejs/biome@d428d76) Thanks [@&#8203;minseong0324](https://github.com/minseong0324)! - [`useExhaustiveSwitchCases`](https://biomejs.dev/linter/rules/use-exhaustive-switch-cases/) now flags missing `true`/`false` cases for `boolean` discriminants, including when `boolean` is a union variant.

- [#&#8203;10125](biomejs/biome#10125) [`a55a0b6`](biomejs/biome@a55a0b6) Thanks [@&#8203;bmish](https://github.com/bmish)! - Fixed a resolver bug where packages that define a typed entry point through `package.json`'s `main` field but omit `types` were ignored during type-aware resolution. Type-aware rules such as [`noFloatingPromises`](https://biomejs.dev/linter/rules/no-floating-promises/) can now inspect imports from those packages.

- [#&#8203;10117](biomejs/biome#10117) [`895e809`](biomejs/biome@895e809) Thanks [@&#8203;denizdogan](https://github.com/denizdogan)! - Added support for the `corner-shape` family of CSS properties and the `superellipse()`/`squircle()` value functions, so [`noUnknownProperty`](https://biomejs.dev/linter/rules/no-unknown-property/) and [`noUnknownFunction`](https://biomejs.dev/linter/rules/no-unknown-function/) no longer flag them as unknown.

  New known properties: `corner-shape`, `corner-block-end-shape`, `corner-block-start-shape`, `corner-bottom-left-shape`, `corner-bottom-right-shape`, `corner-bottom-shape`, `corner-end-end-shape`, `corner-end-start-shape`, `corner-inline-end-shape`, `corner-inline-start-shape`, `corner-left-shape`, `corner-right-shape`, `corner-start-end-shape`, `corner-start-start-shape`, `corner-top-left-shape`, `corner-top-right-shape`, `corner-top-shape`.

  New known value functions: `superellipse()`, `squircle()`.

- [#&#8203;8620](biomejs/biome#8620) [`8df8f73`](biomejs/biome@8df8f73) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;8062](biomejs/biome#8062): Added support for parsing Vue `v-for` directives more accurately.

- [#&#8203;10191](biomejs/biome#10191) [`aa055cd`](biomejs/biome@aa055cd) Thanks [@&#8203;guney](https://github.com/guney)! - Now the rule [`noStaticElementInteractions`](https://biomejs.dev/linter/rules/no-static-element-interactions/) doesn't trigger custom elements.

- [#&#8203;9757](biomejs/biome#9757) [`2c62594`](biomejs/biome@2c62594) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;9099](biomejs/biome#9099): the HTML formatter collapsing non-text children (inline elements, Svelte expressions, comments) onto a single line when the source had them on separate lines. Biome now preserves the user's intended line breaks for exclusively non-text children.

  For example, the following Svelte snippet is now preserved instead of being collapsed to `<div>{name}<!-- comment --></div>`:

  ```svelte
  <div>
    {name}<!-- comment -->
  </div>
  ```

  Similarly, HTML elements like `<span>` inside a `<div>` are now preserved when written on their own line:

  ```html
  <div>
    <span>text</span>
  </div>
  ```

- [#&#8203;10105](biomejs/biome#10105) [`e7c1a6d`](biomejs/biome@e7c1a6d) Thanks [@&#8203;jiwon79](https://github.com/jiwon79)! - Fixed [#&#8203;10039](biomejs/biome#10039): [`useReadonlyClassProperties`](https://biomejs.dev/linter/rules/use-readonly-class-properties/) now detects unreassigned private members in class expressions and export default classes, not only in class declarations.

  The following patterns are now correctly flagged:

  ```ts
  const AnonClass = class {
    #prop = 123;
    constructor() {
      console.log(this.#prop);
    }
  };

  export default class {
    #prop = 123;
    constructor() {
      console.log(this.#prop);
    }
  }
  ```

- [#&#8203;10141](biomejs/biome#10141) [`46a77d0`](biomejs/biome@46a77d0) Thanks [@&#8203;minseong0324](https://github.com/minseong0324)! - Improved [`noUnnecessaryConditions`](https://biomejs.dev/linter/rules/no-unnecessary-conditions/) to detect conditions that are always truthy because they check built-in global class instances such as `Date`, `Map`, `Set`, `WeakMap`, and `Error`.

- [#&#8203;10178](biomejs/biome#10178) [`7b05a89`](biomejs/biome@7b05a89) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;10177](biomejs/biome#10177): The HTML parser no longer reports lowercase `html` or `doctype` text as invalid after void elements such as `<br>`.

- [#&#8203;10155](biomejs/biome#10155) [`0d4595d`](biomejs/biome@0d4595d) Thanks [@&#8203;jiwon79](https://github.com/jiwon79)! - Fixed [#&#8203;10045](biomejs/biome#10045): the CSS formatter no longer compounds indentation inside nested functional pseudo-classes such as `:not(:where(...))`, `:is(:where(...))`, and similar combinations. The same fix also removes one level of unnecessary indentation that was added inside any pseudo-class function whose argument list wrapped onto multiple lines, including `:nth-child(... of ...)`, `::part(...)`, and `:active-view-transition-type(...)`.
  The following snippet is now correctly formatted, matching Prettier.

  ```css
  input:not(
    :where(
      [type="submit"],
      [type="checkbox"],
      [type="radio"],
      [type="button"],
      [type="reset"]
    )
  ) {
    inline-size: 100%;
  }
  ```

- [#&#8203;10112](biomejs/biome#10112) [`6f0251e`](biomejs/biome@6f0251e) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;10110](biomejs/biome#10110): Biome's parser now accepts surrogate code points in JavaScript string `\u{...}` escapes.

- [#&#8203;10141](biomejs/biome#10141) [`46a77d0`](biomejs/biome@46a77d0) Thanks [@&#8203;minseong0324](https://github.com/minseong0324)! - Improved [`noMisleadingReturnType`](https://biomejs.dev/linter/rules/no-misleading-return-type/) to detect `object` return annotations that hide built-in global class instances such as `Date`, `Map`, `Set`, `WeakMap`, and `Error`.

- [#&#8203;10083](biomejs/biome#10083) [`4a664c1`](biomejs/biome@4a664c1) Thanks [@&#8203;ematipico](https://github.com/ematipico)! - Added two new options to [`noShadow`](https://biomejs.dev/linter/rules/no-shadow/), both defaulting to `true` to match typescript-eslint's behavior.

  Fixed [#&#8203;9482](biomejs/biome#9482): Added `ignoreFunctionTypeParameterNameValueShadow` option. When enabled, parameter names inside function type annotations (e.g. `(options: unknown) => void`) are not flagged as shadowing outer variables.

  Fixed [#&#8203;7812](biomejs/biome#7812): Added `ignoreTypeValueShadow` option. When enabled, a value binding that shares its name with a type-only declaration (type alias or interface) is not flagged, since types and values occupy separate namespaces in TypeScript.

- [#&#8203;9286](biomejs/biome#9286) [`52695cf`](biomejs/biome@52695cf) Thanks [@&#8203;Hugo-Polloli](https://github.com/Hugo-Polloli)! - Fixed [#&#8203;6316](biomejs/biome#6316): Biome now resolves Svelte `$store` references to the underlying `store` binding in semantic analysis, preventing false `noUndeclaredVariables` diagnostics when the store is declared.

- [#&#8203;10188](biomejs/biome#10188) [`ae659dd`](biomejs/biome@ae659dd) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Added a new nursery rule [`noExcessiveNestedCallbacks`](https://biomejs.dev/linter/rules/no-excessive-nested-callbacks/), which disallows callbacks nested deeper than the configured maximum.

- [#&#8203;9757](biomejs/biome#9757) [`2c62594`](biomejs/biome@2c62594) Thanks [@&#8203;dyc3](https://github.com/dyc3)! - Fixed [#&#8203;9450](biomejs/biome#9450): the HTML formatter now correctly preserves multiline formatting for nested `<template>` elements (e.g. `<template #body>`) when the source has children on separate lines. Previously, the children were collapsed onto a single line.

  ```diff
   <template>
     <UModal>
  -    <template #body> <p>content</p> </template>
  +    <template #body>
  +      <p>content</p>
  +    </template>
     </UModal>
   </template>
  ```

- [#&#8203;10118](biomejs/biome#10118) [`c6edcb4`](biomejs/biome@c6edcb4) Thanks [@&#8203;Netail](https://github.com/Netail)! - Fixed [#&#8203;10024](biomejs/biome#10024): `biome migrate eslint` correctly migrates `eslint` rules that belong to multiple Biome rules.
