```tsx

type Foo =
Foooooooooooooooooooooooooooooooooooooooooooooooooooooooooo extends []
? Foo3
: Foo4;
// Prettier 2.5.0
type Foo = Foooooooooooooooooooooooooooooooooooooooooooooooooooooooooo extends [
]
? Foo3

##### Fix compatibility with Jest inline snapshot test ([#11892](https://togithub.com/prettier/prettier/pull/11892) by [@fisker](https://togithub.com/fisker))
A internal change in Prettier@v2.5.0 accidentally breaks the Jest inline snapshot test.
##### Support Glimmer's named blocks ([#11899](https://togithub.com/prettier/prettier/pull/11899) by [@duailibe](https://togithub.com/duailibe))
Prettier already supported this feature, but it converted empty named blocks to self-closing, which is not supported by the Glimmer compiler.
See: [Glimmer's named blocks](https://emberjs.github.io/rfcs/0460-yieldable-named-blocks.html).

&:extend(.some-class .some-other-class .some-very-loooooooooooooong-class all);

##### Editor integration: Use [`resolve`](https://www.npmjs.com/package/resolve) if builtin `require.resolve` is overridden ([#8072](https://togithub.com/prettier/prettier/pull/8072) by [@fisker](https://togithub.com/fisker))
This fixes issues that the users of Atom and WebStorm faced with 2.0.4.
Prettier now switches to using the `resolve` module for resolving configuration files and plugins if it detects that `require.resolve` isn't Node's builtin function (doesn't support the second argument), which happens in environments like editor extensions. To force the fallback, set the `PRETTIER_FALLBACK_RESOLVE` environment variable to `true`.

##### TypeScript: Avoid trailing commas on index signatures with only one parameter ([#7836](https://togithub.com/prettier/prettier/pull/7836) by [@bakkot](https://togithub.com/bakkot))
TypeScript index signatures technically allow multiple parameters and trailing commas, but it's an error to have multiple parameters there, and Babel's TypeScript parser does not accept them. So Prettier now avoids putting a trailing comma there when you have only one parameter.
```ts
// Input
export type A = {
a?: {
[
x: string
]: typeof SomeLongLongLongTypeName[keyof typeof SomeLongLongLongTypeName];
} | null;
};
// Prettier 2.0.0
export type A = {
a?: {
[
x: string,
]: typeof SomeLongLongLongTypeName[keyof typeof SomeLongLongLongTypeName];
} | null;
};
// Prettier 2.0.2
export type A = {
a?: {
[
x: string
]: typeof SomeLongLongLongTypeName[keyof typeof SomeLongLongLongTypeName];
} | null;
};
```

##### Other changes

```ts
// Input

// Prettier 2.0.0
