Description

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

##### Markdown: Cap ordered list mark at 999,999,999 ([#&#8203;19351](prettier/prettier#19351) by [@&#8203;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:

## [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:

##### 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[primary];
  color: #theme[@name];
  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 -->

// 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;
}
```

[[Foo:Bar]]

<!-- Prettier 3.9.4 -->

<!-- Prettier 3.9.5 -->

```

##### 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

// 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))

```html
