Add lint rule useJsxKeyInIterable from Eslint rule react/jsx-key. Contributed by @vohoanglong0107
The analyzer now infers the correct quote from javascript.formatter.quoteStyle, if set. This means that code fixes suggested by the analyzer will use the same quote of the formatter. Contributed by @ematipico

Enhancements

noUnusedVariables ignores unused rest spread silbings.
The following code is now valid:
```
const { a, ...rest } = { a: 0, b: 1 };
console.log(rest);
```
Contributed by @ah-yu
Fix #1931. Built-in React hooks such as
useEffect() can now be validated by the
useExhaustiveDependendies, even
when they're not being imported from the React library. To do so, simply configure them like
any other user-provided hooks.
Contributed by @arendjr

Bug fixes

Fix #1748. Now for the following case we won't provide an unsafe fix
for the noNonNullAssertion rule:
```
x[y.z!];
```
Contributed by @ah-yu

Imports that contain the protocol : are now sorted after the npm: modules, and before the URL modules.
Contributed by @ematipico

import express from "npm:express";
- import Component from "./component.js"
- import { sortBy } from "virtual:utils";
+ import { sortBy } from "virtual:utils";
+ import Component from "./component.js"

Fix #1081. The useAwait rule does not report for await...of.
Contributed by @unvalley
Fix #1827 by properly analyzing nested try-finally statements. Contributed by @ah-yu
Fix #1924 Use the correct export name to sort in the import clause. Contributed by @ah-yu
Fix #1805 fix formatting arrow function which has conditional expression body Contributed by @mdm317
Fix #1781 by avoiding the retrieval of the entire static member expression for the reference if the static member expression does not start with the reference. Contributed by @ah-yu

CLI

New features

Add a new command biome migrate prettier. The command will read the file .prettierrc/prettier.json
and .prettierignore and map its configuration to Biome's one.
Due to the different nature of .prettierignore globs and Biome's globs, it's highly advised to make sure that
those still work under Biome.
Now the file name printed in the diagnostics is clickable. If you run the CLI from your editor, you can
Ctrl/⌘ + Click on the file name, and the editor will open said file. If row and columns
are specified e.g. file.js:32:7, the editor will set the cursor right in that position. Contributed by @ematipico
Add an option --linter to biome rage. The option needs to check Biome linter configuration. Contributed by
@seitarof
Add an option --formatter to biome rage. The option needs to check Biome formatter configuration. Contributed by
@seitarof
The CLI now consistently reports the number of files tha were changed, out of the total files that were analysed. Contributed by @ematipico
The CLI now consistently shows the number of errors and warnings emitted. Contributed by @ematipico

Bug fixes

Don't process files under an ignored directory.
Previously, Biome processed all files in the traversed hierarchy,
even the files under an ignored directory.
Now, it completly skip the content of ignored directories.
Fix #1508 by excluding deleted files from being processed. Contributed
by @ematipico
Fix #1173. Fix the formatting of a single instruction with commented
in a control flow body to ensure consistency. Contributed by @mdm317
Fix overriding of javascript.globals. Contributed by @arendjr

Fix a bug where syntax rules weren't run when pulling the diagnostics. Now Biome will emit more parsing diagnostics,
e.g.

check.js:1:17 parse/noDuplicatePrivateClassMembers ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  × Duplicate private class member "#foo"

  > 1 │ class A { #foo; #foo }
      │                 ^^^^

Contributed by @ematipico

Fix #1774 by taking into account the option --no-errors-on-unmatched when running the CLI using --changed. Contributed by @antogyn

Enhancements

Removed a superfluous diagnostic that was printed during the linting/check phase of a file:

test.js check ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  × The file contains diagnostics that needs to be addressed.

Contributed by @ematipico

The command format now emits parsing diagnostics if there are any, and it will terminate with a non-zero exit code. Contributed by @ematipico

Configuration

New features

Add the ability to resolve the configuration files defined inside extends from the node_modules/ directory.
If you want to resolve a configuration file that matches the specifier @org/configs/biome, then your package.json
file must look this:
```
{
  "name": "@org/configs",
  "exports": {
    "./biome": "./biome.json"
  }
}
```
And the biome.json file that "imports" said configuration, will look like this:
```
{
  "extends": "@org/configs/biome"
}
```
Read the documentation to better understand how it
works, expectations and restrictions.

Editors

Bug fixes

Fix a regression where ignored files where formatted in the editor. Contributed by @ematipico

Fix a bug where syntax rules weren't run when pulling the diagnostics. Now Biome will emit more parsing diagnostics,
e.g.

check.js:1:17 parse/noDuplicatePrivateClassMembers ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  × Duplicate private class member "#foo"

  > 1 │ class A { #foo; #foo }
      │                 ^^^^

Contributed by @ematipico

Formatter

New features

Biome now allows to format the package.json file. This is now the default behaviour and users can remove their
workarounds.
If you rely on other tools to format package.json, you'll have to ignore it via configuration. Contributed by
@pattrickrice
New formatter option attributePosition that have similar behavior as
Prettier singleAttributePerLine #1706. Contributed by @octoshikari
Add partial for .astro files. Biome is able to format the frontmatter of the Astro files. Contributed by @ematipico
```
---
- statement ( );
+ statement();
---

<div></div>
```
Add partial for .vue files. Biome is able to format the script block of Vue files. Contributed by @nhedger
```
<script setup lang="ts">
- statement ( );
+ statement();
</script/>

<template></template>
```
Add partial for .svelte files. Biome is able to format the script block of Svelte files. Contributed by @ematipico
```
<script setup lang="ts">
- statement ( );
+ statement();
</script/>

<div></div>
```

Enhancements

composer.json, deno.json, jsconfig.json, package.json and tsconfig.json are no longer protected files.
This means that you can now format them.
If you want to ignore these files, you can use the files.ignore configuration:
```
{
  "files": {
    "ignore": [
      "composer.json",
      "jsconfig.json",
      "package.json",
      "tsconfig.json",
      "typescript.json",
      "deno.json",
      "deno.jsonc"
    ]
  }
}
```
The following files are still protected, and thus ignored:
- composer.lock
- npm-shrinkwrap.json
- package-lock.json
- yarn.lock
Contributed by @pattrickrice and @Conaclos

Bug fixes

Fix #1039. Check unicode width instead of number of bytes when
checking if regex expression is a simple argument.
This no longer breaks.
```
s(/🚀🚀/).s().s();
```
Contributed by @kalleep
Fix #1218, by correctly preserving empty lines in member chains.
Contributed by @ah-yu
Fix #1659 and #1662, by correctly taking into account the leading comma inside the formatter options. Contributed by @ematipico

```
Contributed by @DaniGuardiola
Add rule noUndeclaredependencies, to detect the use of
dependencies that aren't present in the package.json
Add rule noNamespaceImport, to report namespace imports:
```
import * as foo from "foo";
```
Contributed by @unvalley
Add partial support for .astro files. Biome is able to lint and fix the frontmatter of the Astro files. Contributed
by @ematipico
```
---
- delete a.b
+ a.b = undefined
---

<div></div>
```
Add partial support for .vue files. Biome is able to lint and fix the script block of the Vue files. Contributed by
@nhedger
```
<script setup lang="ts">
- delete a.b
+ a.b = undefined
<script>

<template></template>
```
Add rule useNodeAssertStrict, which promotes the use
of node:assert/strict over node:assert. Contributed by @ematipico
Add rule noExportsInTest which disallows export or modules.exports in files
containing test. Contributed by @ah-yu

Add rule noSemicolonInJsx to detect possible wrong semicolons inside JSX elements.

const Component = () => {
  return (
    <div>
      <div />;
    </div>
  );
}

Contributed by @fujiyamaorange

Enhancements

noUselessTernary now provides unsafe code fixes. Contributed by
@vasucp1207
noApproximativeNumericConstant now provides
unsafe code fixes and handle numbers without leading zero and numbers with digit separators.
The following numbers are now reported as approximated constants.
```
3.14_15; // PI
.4342; // LOG10E
```
Contributed by @Conaclos
noPrecisionLoss no longer reports number with extra zeros.

```
.1230000000000000000000000;
1230000000000000000000000.0;
```
Contributed by @Conaclos
useNamingConvention now
supports unicase
letters (#1786).
unicase letters have a single case: they are neither uppercase nor lowercase.
Previously, Biome reported names in unicase as invalid.
It now accepts a name in unicase everywhere.
The following code is now accepted:
```
const 안녕하세요 = { 안녕하세요: 0 };
```
We still reject a name that mixes unicase characters with lowercase or uppercase characters:
The following names are rejected:
```
const A안녕하세요 = { a안녕하세요: 0 };
```
Contributed by @Conaclos
useNamingConvention
and useFilenamingConvention now provides a new option requireAscii to require identifiers to
be in ASCII.
To avoid any breaking change, this option is turned off by default.
We intend to turn it on in the next major release of Biome (Biome 2.0).
Set the requireAscii rule option to true to require identifiers to be in ASCII.
```
{
  "linter": {
    "rules": {
      "style": {
        "useNamingConvention": { "options": { "requireAscii": false } }
      },
      "nursery": {
        "useFilenamingConvention": { "options": { "requireAscii": false } }
      }
    }
  }
}
```

```
Contributed by @lucasweng

Fix #1651. noVar now
ignores TsGlobalDeclaration. Contributed by @vasucp1207
Fix #1640. useEnumInitializers code action now generates valid code when last member has a comment but no comma. Contributed by @kalleep
Fix #1653. Handle a shorthand value in useForOf to avoid the false-positive case. Contributed by @togami2864
Fix #1656. useOptionalChain code action now correctly handles logical and chains where methods with the same name are invoked with different arguments:
```
- tags·&&·tags.includes('a')·&&·tags.includes('b')
+ tags?.includes('a') && tags.includes('b')
```
Contributed by @lucasweng
Fix #1704. Convert / to escaped slash \/ to avoid parsing error in
the result of autofix. Contributed by @togami2864

Contributed by @togami2864
Fix #603. Trim trailing whitespace to avoid double insertion.
Contributed by @togami2864
Fix #1765. Now the rule noDelete doesn't trigger when deleting a
dataset:
```
delete element.dataset.prop;
```
Contributed by @ematipico
useNamingConvention
and useFilenamingConvention now reject identifiers with consecutive delimiters.
The following name is now invalid because it includes two underscores:
```
export const MY__CONSTANT = 0;
```
Note that we still allow consecutive leading and consecutive trailing underscores.
Contributed by @Conaclos
Fix #1932 Allow redeclaration of type parameters in different declarations.
Contributed by @keita-hino
Fix #1945 Allow constructor with default parameters in noUselessConstructor

declare global
{ }

declare module foo {
  global
  { }
}
```
Contributed by @ah-yu
