  • style/useTemplate
  • suspicious/noMisleadingCharacterClass

• Fix #​4190, where the rule noMissingVarFunction wrongly reported a variable as missing when used inside a var() function that was a newline. Contributed by @​ematipico

• Fix #​4041. Now the rule useSortedClasses won't be triggered if className is composed only by inlined variables. Contributed by @​ematipico

• useImportType and useExportType now report useless inline type qualifiers (#​4178).

  The following fix is now proposed:

  - import type { type A, B } from "";
  + import type { A, B } from "";
  
  - export type { type C, D };
  + export type { C, D };

  Contributed by @​Conaclos

• useExportType now reports ungrouped export from.

  The following fix is now proposed:

  - export { type A, type B } from "";
  + export type { A, B } from "";

• noVoidTypeReturn now accepts void expressions in return position (#​4173).

  The following code is now accepted:

  function f(): void {
    return void 0;
  }

  Contributed by @​Conaclos

• noUselessFragments now correctly handles fragments containing HTML escapes (e.g.  ) inside expression escapes { ... } (#​4059).

  The following code is no longer reported:

  function Component() {
    return (
      <div key={index}>{line || <>&nbsp;</>}</div>
    )
  }

  Contributed by @​fireairforce

• noUnusedFunctionParameters and noUnusedVariables no longer reports a parameter as unused when another parameter has a constructor type with the same parameter name (#​4227).

  In the following code, the name parameter is no longer reported as unused.

  export class Foo {
    bar(name: string, _class: new (name: string) => any) {
      return name
    }
  }

• noUndeclaredDependencies now accepts dependency names with dots. Contributed by @​Conaclos

• useFilenamingConvention now correctly handles renamed exports (#​4254).

  The rule allows the filename to be named as one of the exports of the module.
  For instance, the file containing the following export can be named Button.

  class Button {}
  export { Button }

  The rule now correctly handles the renaming of an export.
  For example, the file containing the following export can only be named Button.
  Previously the rule expected the file to be named A.

  class A {}
  export { A as Button }

• useConsistentMemberAccessibility now ignore private class members such as #property (#​4276). Contributed by @​Conaclos

• noUnknownFunction correctly handles calc-size function (#​4212).

  .a { height: calc-size(0px); }

  Contributed by @​fireairforce

• useNamingConvention now allows configuring conventions for readonly index signatures.

Contributed by @​sepruko

• noDuplicateCustomProperties now correctly handles custom properties and ignores non-custom properties.
  Previously, the rule incorrectly reported duplicates for all properties, including non-custom ones. Contributed by @​togami2864

Parser

Bug Fixes

• The CSS parser now accepts more emoji in identifiers (#​3627).

  Browsers accept more emoji than the standard allows.
  Biome now accepts these additional emojis.

  The following code is now correctly parsed:

  p {
    --✨-color: red;
    color: var(--✨-color);
  }

• Add support for parsing typescript's resolution-mode in Import Types(#​2115)

  export type Fs = typeof import('fs', { with: { 'resolution-mode': 'import' } });
  export type TypeFromRequire =
    import("pkg", { with: { "resolution-mode": "require" } }).TypeFromRequire;
  export type TypeFromImport =
    import("pkg", { with: { "resolution-mode": "import" } }).TypeFromImport;
