##### Fix config file search ([#15363](https://togithub.com/prettier/prettier/pull/15363) by [@fisker](https://togithub.com/fisker))
Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.
```text
├─ .prettierrc
└─ test.js (A directory)
└─ .prettierrc
```
```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// /test.js/.prettierrc
// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// /.prettierrc
```
##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](https://togithub.com/prettier/prettier/pull/15533) by [@sanmai-NL](https://togithub.com/sanmai-NL))
Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.
In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.
##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](https://togithub.com/prettier/prettier/pull/15662) by [@auvred](https://togithub.com/auvred))
```jsx
// Input
aaaaaaaaaaaaaaa
? bbbbbbbbbbbbbbbbbb
: ccccccccccccccc
? ddddddddddddddd
: eeeeeeeeeeeeeee
? fffffffffffffff
: gggggggggggggggg;
// Prettier 3.1.0
aaaaaaaaaaaaaaa
? bbbbbbbbbbbbbbbbbb
: ccccccccccccccc
? ddddddddddddddd
: eeeeeeeeeeeeeee
? fffffffffffffff
: gggggggggggggggg;
// Prettier 3.1.1
aaaaaaaaaaaaaaa
? bbbbbbbbbbbbbbbbbb
: ccccccccccccccc
? ddddddddddddddd
: eeeeeeeeeeeeeee
? fffffffffffffff
: gggggggggggggggg;
```
##### Improve config file search ([#15663](https://togithub.com/prettier/prettier/pull/15663) by [@fisker](https://togithub.com/fisker))
The Prettier config file search performance has been improved by more effective cache strategy.
##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](https://togithub.com/prettier/prettier/pull/15708) by [@sosukesuzuki](https://togithub.com/sosukesuzuki))
```tsx
// Input
const {
foo,
// bar
// baz
}: Foo = expr;
// Prettier 3.1.0
const {
foo1,
} // bar
// baz
: Foo = expr;
// Prettier 3.1.0 second output
const {
foo1, // bar
} // baz
: Foo = expr;
// Prettier 3.1.1
const {
foo1,
// bar
// baz
}: Foo = expr;
```
##### Support "Import Attributes" ([#15718](https://togithub.com/prettier/prettier/pull/15718) by [@fisker](https://togithub.com/fisker))
[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://togithub.com/tc39/proposal-import-attributes) proposal.
```tsx
import something from "./something.json" with { type: "json" };
```
##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](https://togithub.com/prettier/prettier/pull/15750) by [@ExplodingCabbage](https://togithub.com/ExplodingCabbage))
The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://togithub.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.
##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](https://togithub.com/prettier/prettier/pull/15756) by [@fisker](https://togithub.com/fisker))
```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';
// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";
// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```
##### Keep empty import attributes and assertions ([#15757](https://togithub.com/prettier/prettier/pull/15757) by [@fisker](https://togithub.com/fisker))
```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};
// Prettier 3.1.0
import foo from "foo";
import bar from "bar";
// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};

##### Add `preferUnplugged: true` to `package.json` ([#15169](https://togithub.com/prettier/prettier/pull/15169) by [@fisker](https://togithub.com/fisker) and [@so1ve](https://togithub.com/so1ve))
Prettier v3 uses dynamic imports, user [will need to unplug Prettier](https://togithub.com/yarnpkg/berry/pull/5411#issuecomment-1523502224) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.
##### Support shared config that forbids `require()` ([#15233](https://togithub.com/prettier/prettier/pull/15233) by [@fisker](https://togithub.com/fisker))
If an external shared config package is used, and the package `exports` don't have `require` or `default` export.
In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.
```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in /package.json
```
##### Allow argument of `require()` to break ([#15256](https://togithub.com/prettier/prettier/pull/15256) by [@fisker](https://togithub.com/fisker))
```jsx
// Input
const plugin = require(
global.STANDALONE
? path.join(__dirname, "../standalone.js")
: path.join(__dirname, "..")
);
// Prettier 3.0.2
const plugin = require(global.STANDALONE

// Prettier 3.0.3
const plugin = require(
global.STANDALONE
? path.join(__dirname, "../standalone.js")
: path.join(__dirname, "..")
);
```
##### Do not print trailing commas in arrow function type parameter lists in `ts` code blocks ([#15286](https://togithub.com/prettier/prettier/pull/15286) by [@sosukesuzuki](https://togithub.com/sosukesuzuki))
````md
```ts
const foo = () => {}

##### Support TypeScript 5.2 `using` / `await using` declaration ([#15321](https://togithub.com/prettier/prettier/pull/15321) by [@sosukesuzuki](https://togithub.com/sosukesuzuki))
Support for the upcoming Explicit Resource Management feature in ECMAScript. [`using` / `await using` declaration](https://devblogs.microsoft.com/typescript/announcing-typescript-5-2/#using-declarations-and-explicit-resource-management)
```tsx
{

##### Fix cursor positioning for a special case ([#14812](https://togithub.com/prettier/prettier/pull/14812) by [@fisker](https://togithub.com/fisker))
```js
// <|> is the cursor position
/* Input */

/* Prettier 3.0.1 */
function a(b) {
if (b) return 1; // comment

}
```
##### Add missing type definition for `printer.preprocess` ([#15123](https://togithub.com/prettier/prettier/pull/15123) by [@so1ve](https://togithub.com/so1ve))
```diff
export interface Printer {
// ...

TypeScript 5.0 introduces two new syntactic features:
- `const` modifiers for type parameters
- `export type *` declarations
##### Add missing parentheses for decorator ([#14393](https://togithub.com/prettier/prettier/pull/14393) by [@fisker](https://togithub.com/fisker))

##### Add parentheses for `TypeofTypeAnnotation` to improve readability ([#14458](https://togithub.com/prettier/prettier/pull/14458) by [@fisker](https://togithub.com/fisker))
```tsx

##### Support `max_line_length=off` when parsing `.editorconfig` ([#14516](https://togithub.com/prettier/prettier/pull/14516) by [@josephfrazier](https://togithub.com/josephfrazier))
If an .editorconfig file is in your project and it sets `max_line_length=off` for the file you're formatting,
it will be interpreted as a `printWidth` of `Infinity` rather than being ignored
(which previously resulted in the default `printWidth` of 80 being applied, if not overridden by Prettier-specific configuration).

##### Group params in opening block statements ([#14067](https://togithub.com/prettier/prettier/pull/14067) by [@jamescdavis](https://togithub.com/jamescdavis))
This is a follow-up to [#13930](https://togithub.com/prettier/prettier/issues/13930) to establish wrapping consistency between opening block statements and else blocks by
grouping params in opening blocks. This causes params to break to a new line together and not be split across lines
unless the length of params exceeds the print width. This also updates the else block wrapping to behave exactly the
same as opening blocks.
```hbs
{{! Input }}
{{#block param param param param param param param param param param as |blockParam|}}
Hello
{{else block param param param param param param param param param param as |blockParam|}}

##### Ignore files in `.sl/` ([#14206](https://togithub.com/prettier/prettier/pull/14206) by [@bolinfest](https://togithub.com/bolinfest))
In [Sapling SCM](https://sapling-scm.com/), `.sl/` is the folder where it stores its state, analogous to `.git/` in Git. It should be ignored in Prettier like the other SCM folders.
##### Recognize `@satisfies` in Closure-style type casts ([#14262](https://togithub.com/prettier/prettier/pull/14262) by [@fisker](https://togithub.com/fisker))
