ea9dd8aThanks @dyc3! - Improved performance ofnoImportCycles.#11247
52b44d6Thanks @dyc3! - Added the nursery rulenoSvelteLegacyConst, which disallows legacy Svelte{@const}tags and recommends declaration tags with$derived().Invalid:

bca1f73Thanks @denbezrukov! - Fixed #11280: CSS formatting keeps comments inside functional pseudo-classes and pseudo-elements instead of moving them before the function name.#11080
af16a0bThanks @dyc3! - HTMLstyleattribute values are now parsed as CSS. All Biome CSS lint rules are applied to thestyleattributes.#11195
6a85588Thanks @dyc3! - Fixed Svelte files failing to parse when an expression begins with an object literal.Now the following snippet is correctly parsed:
#11173
481d008Thanks @Austin1serb! - Fixed #10242: JavaScript GritQL patterns with multiple metavariables now match snippets consistently in WebAssembly.#11187
23c0369Thanks @ematipico! - Added the nursery rulenoInvalidPropertyInitValue, which reports an@propertywhoseinitial-valuedoes not match itssyntaxdescriptor. For example, the following declaration triggers the rule becauseredis not a<length>:#11272
73896e6Thanks @ematipico! - Improved the diagnostic emitted bynoRootType.#11240
bd0b68dThanks @ematipico! - Fixed #11223: Improved theperformance of
noMisusedPromiseswhen analyzing async class methods that call other methods through
this.#11172
4a0bc5cThanks @saberoueslati! - Fixed #10806:noUselessFragmentsno longer causes Biome to panic when its unsafe fix removes a fragment used as a JSX attribute value.#11227
4d603b0Thanks @saberoueslati! - Fixed #11178:noUndeclaredVariablesno longer reports Vue's built-in instance properties, such as$slotsand$attrs, in template expressions or$eventin inline event-handler expressions.

23c0369Thanks @ematipico! - Fixed CSS parsing of registered custom properties: Biome now correctly validates thesyntaxdescriptor of@propertyrules.v2.5.7Compare Source
Patch Changes
#10822
c171b3bThanks @pkallos! - Added the optionignoreIfStatementsto useNullishCoalescing. Biome now flagsifstatements that only assign to a nullish variable (such asif (!a) { a = b }) and can rewrite them to??=. When enabled, Biome ignores thoseifstatements.#11136
e63354cThanks @AkashNaickar! - Added a new nursery rulenoExtendNative, which reports extending the prototype of a built-in object.#10094
e007143Thanks @THEjacob1000! - Added the nursery rulenoTailwindArbitraryValue. Biome now reports Tailwind CSS arbitrary values such asw-[400px], including in HTML/JSX class attributes, configured utility functions, and tagged templates.#11184
135f476Thanks @subotac! - Fixed #11176:noUnknownPseudoClassnow recognizes Vue's:deep()pseudo-class inside.vuestyle blocks.#8239
a519f9dThanks @cormacrelf! - Fixed #8233, where Biome CLI instdin mode didn't work correctly when handling files in projects with nested
configurations. For example, with the following structure,
--stdin-file-path=subdirectory/...would not use the nested configuration insubdirectory/biome.json:biome format --write --stdin-file-path=subdirectory/lib.js < subdirectory/lib.jsNow, the nested configuration is correctly picked up and applied.
In addition, Biome now shows a warning if
--stdin-file-pathis provided butthat path is ignored and therefore not formatted or fixed.
#11138
8c2c6bdThanks @ematipico! - FixednoUnnecessaryConditions: Biome now chooses the same function overload as TypeScript when an argument is a callback, so conditions that were previously missed are reported.The following code is now invalid, because a parameter typed
() => voidaccepts anasynccallback andscheduletherefore returnsstring:The following code is also now invalid, because
map(() => 42)returns42:#11138
8c2c6bdThanks @ematipico! - Fixed #11087:noUnnecessaryConditionsno longer reports optional chains and nullish coalescing whose receiver can be nullish.For example, the optional chain and fallback in the following code are no longer reported:
#11118
9c16840Thanks @subotac! - Fixed #11098: The HTML formatter now preserves the configured trailing newline when a file ends with a comment.#11201
0e80610Thanks @Bishwas-py! - Fixed #11182: suppression comments fornoPositiveTabindexnow suppress the rule in HTML files when the attributes of the element span multiple lines.#11079
607afd2Thanks @dyc3! - The HTML formatter now lays out thesrcsetattribute of<img>and<source>as the list of candidates it is. Runs of whitespace between candidates collapse, and once the list no longer fits on one line each candidate goes on its own line with the descriptors aligned:#11156
fed72c7Thanks @saberoueslati! - Fixed #11129:noUnusedVariablesno longer reports Vue bindings as unused when they are assigned through automatically unwrapped template refs.#11124
d890b39Thanks @denbezrukov! - Fixed CSS formatting of line comments between a declaration colon and value to preserve their source indentation..test { background: - /////// foo - // bar + /////// foo + // bar radial-gradient(circle, #​000, transparent); }#11113
3d8ab73Thanks @denbezrukov! - Fixed CSS formatting of long block comments between comma-separated property values:.foo { box-shadow: - 1000px /* long long long long long long long long long long long long comment */ 1000px /* long long long long long long long long long comment */ 2px color(srgb 0.555555555 0.555555555 0.555555555), + 1000px + /* long long long long long long long long long long long long comment */ + 1000px /* long long long long long long long long long comment */ 2px + color(srgb 0.555555555 0.555555555 0.555555555), 1px 1px black; }#11127
da5c1a5Thanks @dyc3! - The HTML formatter now picks the quote character for an attribute by counting the quotes in the value rather than looking only for a double quote.'and"count as the characters they stand for, and only the character that ends up as the delimiter stays escaped:Entities that are not quotes, such as
&or&[#​39](https://redirect.github.com/biomejs/biome/issues/39);, are left exactly as written.#11193
77035bbThanks @dyc3! - Fixed the HTML formatter collapsing the blank line between an element and the text that follows it. A blank line before text is now kept, the way one before another element already was:<div>foo</div> - text#11106
ad80f57Thanks @dyc3! - The HTML formatter now writes the HTML5 doctype in lowercase, matching Prettier:This only applies to a plain
.htmlfile whose doctype stands alone. A doctype that names a DTD keeps the case it was written with, since the rest of the declaration is not lowercased either:<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">A
.vue,.svelte, or.astrofile keeps whatever the author wrote.#11188
60679dbThanks @dyc3! - Fixed the HTML formatter printing a comment twice when it ended the line of the last element in a document:#11077
4dcd0d9Thanks @dyc3! - Fixed a bug where the HTML formatter collapsed the whitespace inside<textarea>,<xmp>and<plaintext>, changing what the page renders.Biome now prints the content of these elements exactly as it appears in the source, matching the existing behavior for
<pre>.#11194
abfbb11Thanks @dyc3! - Fixed the HTML formatter refusing to format a Svelte file containing an array pattern that skips a position:{#each animals as [, value]} <p>{value}</p> {/each}#10094
e007143Thanks @THEjacob1000! - FixeduseSortedClassesto correctly detect unsorted classes in static member expression tagged templates (e.g.tw.div\...``). Previously, these were silently skipped due to surrounding whitespace trivia not being stripped from the tag name.#11078
10da30eThanks @dyc3! - Fixed Vue single-file components failing to parse when they contain a custom block such as<i18n>or<docs>, or a<template>written in another language. Their content is no longer read as HTML, so a block may hold whatever its own tooling expects:Previously both blocks produced a parse error and the whole file was left unformatted. Biome now prints their content unchanged while still formatting the opening tag.
#11231
4afd901Thanks @ematipico! - Improved the performance of the following lint rules:noArguments.noGlobalAssign.noUndeclaredVariables.noRestrictedGlobals.noInvalidUseBeforeDeclaration.noShadow.noRedeclare.#11134
2fa0a62Thanks @yanthomasdev! - Clarified the warning emitted when using the experimentaljsonandjson-prettyreporters.#11198
ed88b13Thanks @saberoueslati! - Fixed #11171: variables referenced only inside a Svelte attachment ({@attach ...}) are no longer reported as unused bynoUnusedVariablesandnoUnusedImports.#11155
6ee17eaThanks @dyc3! - Improved performance when printing diagnostics to the console.#11160
217f8adThanks @dyc3! - Improved the performance ofnoFloatingPromisesby skipping type inference for assignment statements, which are always considered handled.#11159
26c23d9Thanks @saberoueslati! - Fixed #11144:noFloatingPromisesno longer reports already-awaited optional Promise values.#11138
8c2c6bdThanks @ematipico! - Fixed #11121:noUnnecessaryConditionsno longer reports conditions based on an inapplicable function overload.For example, the condition in the following code is no longer reported because
query({})selects the overload that returnsboolean:#11152
c4fc6a9Thanks @dyc3! - Improved the performance of collecting rule timings with--profile-rulesin heavily multithreaded environments.#11128
4d3ff76Thanks @ematipico! - Fixed #7635:noDeprecatedImportsnow detects deprecated ambient declarations that are exported separately.#11117
01f7ef5Thanks @subotac! - Fixed #11014:noDeleteno longer reportsprocess.env["FOO"]style property deletions.#11168
9847e68Thanks @saberoueslati! - Added the nursery rulenoNonScalableViewport, which reports viewport metadata that disables user scaling withuser-scalable=no.For example:
#11154
a1d6b1fThanks @dyc3! - Improved the performance ofnoImportCyclesby skipping graph traversals for imports that cannot be part of a cycle.#11175

Patch Changes
#11035
0e4b03bThanks @ematipico! - Fixed a performance regression innoMisusedPromisesthat caused type inference to run repeatedly while linting a file.#11043
22ec076Thanks @denbezrukov! - Fixed CSS formatting for multiline function arguments preceded by comments:.example { value: outer( 1, /* comment */ nested( - first, - second - ) + first, + second + ) ); }#11007

50a9bd8Thanks @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
8ffe2b9Thanks @dadavidtseng! - Fixed #11092: ThenoUselessTernaryquick fix now preserves operator spacing when simplifying or inverting boolean ternary expressions.#10533
5809875Thanks @Mokto! - Fixed #10515:biome check --writewas 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
0abb620Thanks @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
6d18204Thanks @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
2c36626Thanks @ematipico! - Improved the accuracy of type-aware lint rules by resolving more inferred types. For example,noFloatingPromisesnow detects floating Promises returned by aliased callbacks and arrays of Promises created by async mapping callbacks.The following statements are now reported:
#10973
9cb044cThanks @ematipico! - Fixed false positives innoMisleadingReturnTypewhen 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:#11071
15047a2Thanks @dyc3! - The HTML parser now accepts mixed-casedoctypedeclarations.#11030
cc90e65Thanks @marschattha! - Therdjsonreporter now populates the severity field of each diagnostic (ERROR,WARNING, orINFO), so tools consuming Reviewdog Diagnostic Format output no longer need to assume a default severity.#11009
2c36626Thanks @ematipico! - Fixed a performance regression in type-aware JavaScript lint rules by inferring only requested types and memoizing export resolution.#11056
903b177Thanks @dyc3! - Added support for Svelte declaration tags usingletandconst. Biome can now parse, format, and lint bindings declared in these tags.#11045
89c27c6Thanks @ematipico! - Improved the performance of Biome formatter up to ~7% across the board.#9806
781d68dThanks @dyc3! - Added the nursery rulenoJsRestrictedProperties, which ports ESLint'sno-restricted-propertiesrule. Biome now flags restricted member access and object destructuring, andbiome migrate eslintpreserves the rule's options.Configuration
