##### Markdown: Cap ordered list mark at 999,999,999 ([#19351](prettier/prettier#19351) by [@tats-u](https://github.com/tats-u))

CommonMark parsers only support ordered list item numbers up to 999,999,999.

With this change, Prettier now caps the ordered list item number at 999,999,999 to ensure that the output is correctly parsed as an ordered list by CommonMark parsers. Numbers larger than 999,999,999 are not parsed as list item numbers and are left unchanged in the output:

##### Markdown: Avoid corrupting empty link with title ([#19487](prettier/prettier#19487) by [@andersk](https://github.com/andersk))

Do not remove `<>` from an inline link or image with an empty URL and a title, as this removal would change its interpretation.

<!-- prettier-ignore -->

```md
<!-- Input -->
[link](<> "title")

<!-- Prettier 3.9.4 -->

<!-- Prettier 3.9.5 -->

##### CSS: Prevent addition space in `type()` with `+` ([#19516](prettier/prettier#19516) by [@bigandy](https://github.com/bigandy))

This fixes the addition space before `+` in CSS `type()` declaration. For example `type(<number>+)` was being converted into `type(<number> +)` which is invalid CSS and does not work.

<!-- prettier-ignore -->

```css
/* Input */
div {

##### Markdown: Cap ordered list mark at 999,999,999 ([#19351](prettier/prettier#19351) by [@tats-u](https://github.com/tats-u))

CommonMark parsers only support ordered list item numbers up to 999,999,999.

With this change, Prettier now caps the ordered list item number at 999,999,999 to ensure that the output is correctly parsed as an ordered list by CommonMark parsers. Numbers larger than 999,999,999 are not parsed as list item numbers and are left unchanged in the output:

##### Markdown: Avoid corrupting empty link with title ([#19487](prettier/prettier#19487) by [@andersk](https://github.com/andersk))

Do not remove `<>` from an inline link or image with an empty URL and a title, as this removal would change its interpretation.

<!-- prettier-ignore -->

<!-- Input -->

##### CSS: Prevent addition space in `type()` with `+` ([#19516](prettier/prettier#19516) by [@bigandy](https://github.com/bigandy))

This fixes the addition space before `+` in CSS `type()` declaration. For example `type(<number>+)` was being converted into `type(<number> +)` which is invalid CSS and does not work.

<!-- prettier-ignore -->

/* Input */
div {

##### Markdown: Preserve single tildes in Markdown ([#19739](prettier/prettier#19739) by [@lazerg](https://github.com/lazerg))

Since 3.9.0, single-tilde spans like `H~2~O` were rewritten to double tildes, turning subscript syntax into strike-through. Only double tildes are treated that way now, matching GitHub.

<!-- Input -->
H~2~O

H~~2~~O

##### JavaScript: Added a new official plugin `@prettier/plugin-yuku` ([#19628](prettier/prettier#19628), [#19629](prettier/prettier#19629) by [@fisker](https://github.com/fisker))

`@prettier/plugin-yuku` is powered by [Yuku](https://yuku.fyi/) (A high-performance JavaScript/TypeScript compiler toolchain written in Zig).

This plugin includes two new parsers: `yuku` (JavaScript syntax) and `yuku-ts` (TypeScript syntax).

**To use this plugin:**

1. Install the plugin:

   ```bash
   yarn add --dev prettier @prettier/plugin-yuku
   ```

2. Add it to your `.prettierrc`:

   ```yaml
   plugins:
     - "@prettier/plugin-yuku"
   ```

Due to package size limitations, this plugin is not bundled with the main prettier package and must be installed separately.

For more information, check [the package homepage](https://github.com/prettier/prettier/tree/main/packages/plugin-yuku).

Big thanks to [@arshad-yaseen](https://github.com/arshad-yaseen) for his excellent work.


## [v3.9.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#395)

[diff](prettier/prettier@3.9.4...3.9.5)

##### Markdown: Cap ordered list mark at 999,999,999 ([#19351](prettier/prettier#19351) by [@tats-u](https://github.com/tats-u))

CommonMark parsers only support ordered list item numbers up to 999,999,999.

With this change, Prettier now caps the ordered list item number at 999,999,999 to ensure that the output is correctly parsed as an ordered list by CommonMark parsers. Numbers larger than 999,999,999 are not parsed as list item numbers and are left unchanged in the output:

<!-- prettier-ignore -->

```markdown
<!-- Input -->
999999998. text
999999998. text
999999998. text
999999998. text

1234567890123456789012) text

<!-- Prettier 3.9.4 -->

##### Markdown: Avoid corrupting empty link with title ([#19487](prettier/prettier#19487) by [@andersk](https://github.com/andersk))

Do not remove `<>` from an inline link or image with an empty URL and a title, as this removal would change its interpretation.

<!-- prettier-ignore -->

```md
<!-- Input -->
[link](<> "title")

<!-- Prettier 3.9.4 -->
[link]( "title")

<!-- Prettier 3.9.5 -->
[link](<> "title")
```

##### Less: Remove extra spaces after `[` in map lookups ([#19503](prettier/prettier#19503) by [@kovsu](https://github.com/kovsu))

<!-- prettier-ignore -->

```less
// Input
.foo {
  color: #theme[ primary];
  color: #theme[@name];
  color: #theme[@@name];
}

// Prettier 3.9.4
.foo {
  color: #theme[ primary];
  color: #theme[ @name];
  color: #theme[ @@name];
}

// Prettier 3.9.5
.foo {

  color: #theme[@@name];
}
```

##### CSS: Prevent addition space in `type()` with `+` ([#19516](prettier/prettier#19516) by [@bigandy](https://github.com/bigandy))

This fixes the addition space before `+` in CSS `type()` declaration. For example `type(<number>+)` was being converted into `type(<number> +)` which is invalid CSS and does not work.

<!-- prettier-ignore -->

```css
/* Input */
div {
  border-radius: attr(br type(<length>+));
}

/* Prettier 3.9.4 */
div {
  border-radius: attr(br type(<length> +));
}

/* Prettier 3.9.5 */
div {
  border-radius: attr(br type(<length>+));
}
```

##### Less: Remove spaces between merge markers and colons ([#19517](prettier/prettier#19517) by [@kovsu](https://github.com/kovsu))

<!-- prettier-ignore -->

```less
// Input
a {
  box-shadow  +  : 0 0 1px #000;
}

// Prettier 3.9.4
a {
  box-shadow+  : 0 0 1px #000;
}

// Prettier 3.9.5
a {
  box-shadow+: 0 0 1px #000;
}
```

<!-- Prettier 3.9.4 -->
[[Foo]]

<!-- Prettier 3.9.5 -->
[[Foo:Bar]]
```

##### TypeScript: Fix comments being dropped on shorthand `type` import/export specifiers ([#19565](prettier/prettier#19565) by [@kirkwaiblinger](https://github.com/kirkwaiblinger))

<!-- prettier-ignore -->

```tsx
// Input
export { type /* comment */ T } from "foo";
import { type /* comment */ T } from "foo";

// Prettier 3.9.4
Error: Comment "comment" was not printed. Please report this error!

// Prettier 3.9.5
export { type /* comment */ T } from "foo";
import { type /* comment */ T } from "foo";
```

##### Miscellaneous: Preserving comments' `placement` property ([#19567](prettier/prettier#19567) by [@Janther](https://github.com/Janther))

Prettier\@3.9.0 deleted an undocumented property on comments, which was already used by plugins, `comment.placement` is now available again after comment attach.

##### Flow: Stop enforcing empty module declaration to break ([#19568](prettier/prettier#19568) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

  @default never(state);
}

<!-- Prettier 3.9.4 -->
@switch (state.mode) {
  @default never;

<!-- Prettier 3.9.5 -->
@switch (state.mode) {
  @default never(state);
}
```

##### TypeScript: Ignore comments inside mapped type when checking type parameter comments ([#19572](prettier/prettier#19572) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```tsx
// Input

  // comment
  [key in keyof Foo]: number
