2.5.6

Patch Changes

  • #11035 0e4b03b Thanks @ematipico! - Fixed a performance regression in noMisusedPromises that caused type inference to run repeatedly while linting a file.

  • #11043 22ec076 Thanks @denbezrukov! - Fixed CSS formatting for multiline function arguments preceded by comments: 

     .example {
   value: outer(
     1,
     /* comment */
     nested(
-      first,
-      second
-    )
+        first,
+        second
+      )
   );
 }

  • #11007 c9acb25 Thanks @BTF-Kabir-2020! - Fixed #9195: useHookAtTopLevel no longer reports hooks in named forwardRef components that receive a ref parameter.

  • #10152 50a9bd8 Thanks @Zelys-DFKH! - Fixed #10131: Biome now correctly parses curried arrow functions in ternary consequents when the inner arrow's parameters use a destructuring pattern, e.g. cond ? (x) => ({ a, b }) => body : alt.

  • #11105 8ffe2b9 Thanks @dadavidtseng! - Fixed #11092: The noUselessTernary quick fix now preserves operator spacing when simplifying or inverting boolean ternary expressions.

  • #10533 5809875 Thanks @Mokto! - Fixed #10515: biome check --write was not idempotent on Svelte files — multi-line template literals in <script> blocks and block comments in <style> blocks gained an extra indent level on every run.

  • #11040 0abb620 Thanks @Mokto! - Fixed an issue where the HTML formatter would duplicate a comment placed directly before a Svelte {@const ...} or {@debug ...} block. The duplication compounded on every subsequent --write, causing the file to grow exponentially.

  • #10858 6d18204 Thanks @ruidosujeira! - Fixed #10839: Svelte {#each} array destructuring no longer includes spaces inside square brackets, and multiline bind function expressions now indent their getter, setter, and function body correctly.

  • #11009 2c36626 Thanks @ematipico! - Improved the accuracy of type-aware lint rules by resolving more inferred types. For example, noFloatingPromises now detects floating Promises returned by aliased callbacks and arrays of Promises created by async mapping callbacks.

    The following statements are now reported: 

    type AsyncCallback = () => Promise<void>;
declare const callback: AsyncCallback;
callback();

[1, 2, 3].map(async (value) => value);

  • #10973 9cb044c Thanks @ematipico! - Fixed false positives in noMisleadingReturnType when generic-constraint, normalization, substitution, or structural return-type comparison cannot complete. The rule now suppresses diagnostics rather than suggesting a return type derived from partial information. For example, this unresolved return type is no longer reported: 

    function unresolvedReturnType(): MissingType {
  return "value" as const;
}

  • #11071 15047a2 Thanks @dyc3! - The HTML parser now accepts mixed-case doctype declarations.

  • #11030 cc90e65 Thanks @marschattha! - The rdjson reporter now populates the severity field of each diagnostic (ERROR, WARNING, or INFO), so tools consuming Reviewdog Diagnostic Format output no longer need to assume a default severity.

  • #11009 2c36626 Thanks @ematipico! - Fixed a performance regression in type-aware JavaScript lint rules by inferring only requested types and memoizing export resolution.

  • #11056 903b177 Thanks @dyc3! - Added support for Svelte declaration tags using let and const. Biome can now parse, format, and lint bindings declared in these tags.

  • #11045 89c27c6 Thanks @ematipico! - Improved the performance of Biome formatter up to ~7% across the board.

  • #9806 781d68d Thanks @dyc3! - Added the nursery rule noJsRestrictedProperties, which ports ESLint's no-restricted-properties rule. Biome now flags restricted member access and object destructuring, and biome migrate eslint preserves the rule's options.
