##### Less: Fix formatting of `:extend` ([#7984](https://togithub.com/prettier/prettier/pull/7984) by [@fisker](https://togithub.com/fisker))
```less
// Input
.class {
&:extend(.some-class .some-other-class .some-very-loooooooooooooong-class all);
}
// Prettier 2.0.4

##### 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;
};
```

- TypeScript: Add trailing comma in tsx, only for arrow function ([#6190] by [@sosukesuzuki])
Prettier inserts a trailing comma to single type parameter for arrow functions in tsx, since v 1.18. But, this feature inserts a trailing comma to type parameter for besides arrow functions too (e.g, function , interface). This change fix it.
```tsx
// Input
interface Interface1 {
one: "one";
}
function function1() {
return "one";
}
// Output (Prettier 1.18.0)
interface Interface1 {
one: "one";

```
- Config: Match dotfiles in config overrides ([#6194] by [@duailibe])
When using [`overrides`](https://prettier.io/docs/en/configuration.html#configuration-overrides) in the config file, Prettier was not matching dotfiles (files that start with `.`). This was fixed in 1.18.1

- JavaScript: Fix closure compiler typecasts ([#5947] by [@jridgewell])
If a closing parenthesis follows after a typecast in an inner expression, the typecast would wrap everything to the that following parenthesis.
```js
// Input

test(/** @type {!Array} */((arrOrString)).length + 1);
// Output (Prettier 1.17.0)
test(/** @type {!Array} */ (arrOrString.length));
test(/** @type {!Array} */ (arrOrString.length + 1));
// Output (Prettier 1.17.1)

- JavaScript: Improved multiline closure compiler typecast comment detection ([#6070] by [@yangsu])
Previously, multiline closure compiler typecast comments with lines that

```js
// Input

*/({
width,
});
// Output (Prettier 1.17.0)
const style =/**

- API: Fix `prettier.getSupportInfo()` reporting babel parser for older versions of Prettier. ([#5826] by [@azz])
In version `1.16.0` of Prettier, the `babylon` parser was renamed to `babel`. Unfortunately this lead to a minor breaking change: `prettier.getSupportInfo('1.15.0')` would report that it supported `babel`, not `babylon`, which breaks text-editor integrations. This has now been fixed.

There's an internal change introduced in Prettier 1.16.2,
which updated `typescript-estree` to its new package name,
but unfortunately it broke the output
so we reverted it as a temporary workaround for now.

- CLI: Fix CI detection to avoid unwanted TTY behavior ([#5804] by [@kachkaev])
In Prettier 1.16.0 and 1.16.1, `--list-different` and `--check` logged every file in some CI environments, instead of just unformatted files.
This unwanted behavior is now fixed.
- HTML: Do not format non-normal whitespace as normal whitespace ([#5797] by [@ikatyang])
Previously, only non-breaking whitespaces (U+00A0) are marked as non-normal whitespace,
which means other non-normal whitespaces such as non-breaking narrow whitespaces (U+202F)
could be formatted as normal whitespaces, which breaks the output. We now follow the spec to
exclude all non-[ASCII whitespace](https://infra.spec.whatwg.org/#ascii-whitespace) from whitespace normalization.
(`·` represents a non-breaking narrow whitespace)

- JavaScript: Add necessary parentheses for decorators ([#5785] by [@ikatyang])
Parentheses for decorators with nested call expressions are optional for legacy decorators
but they're required for decorators in the current [proposal](https://tc39.github.io/proposal-decorators/#sec-syntax).
```js
// Input
class X {
@(computed().volatile())
prop
}
// Output (Prettier 1.16.0)
class X {
@computed().volatile()
prop
}
// Output (Prettier 1.16.1)
class X {
@(computed().volatile())
prop
}
```
- TypeScript: Stable parentheses for function type in the return type of arrow function ([#5790] by [@ikatyang])
There's a regression introduced in 1.16 that
parentheses for function type in the return type of arrow function were kept adding/removing.
Their parentheses are always printed now.
```ts
// Input
const foo = (): (() => void) => (): void => null;
const bar = (): () => void => (): void => null;
// First Output (Prettier 1.16.0)
const foo = (): () => void => (): void => null;
const bar = (): (() => void) => (): void => null;
// Second Output (Prettier 1.16.0)
const foo = (): (() => void) => (): void => null;
const bar = (): () => void => (): void => null;
// Output (Prettier 1.16.1)
const foo = (): (() => void) => (): void => null;
const bar = (): (() => void) => (): void => null;
```
- MDX: Correctly recognize inline JSX ([#5783] by [@ikatyang])
Previously, some inline JSXs are wrongly recognized as block HTML/JSX,
which causes unexpected behaviors. This issue is now fixed.
```md
_foo bar_
_foo
bar_
_foo bar_
```

### [`v2.0.5`](https://togithub.com/prettier/prettier/blob/master/CHANGELOG.md#205) [Compare Source](https://togithub.com/prettier/prettier/compare/2.0.4...2.0.5) [diff](https://togithub.com/prettier/prettier/compare/2.0.4...2.0.5) ##### Less: Fix formatting of `:extend` ([#7984](https://togithub.com/prettier/prettier/pull/7984) by [@fisker](https://togithub.com/fisker)) ```less // Input .class { &:extend(.some-class .some-other-class .some-very-loooooooooooooong-class all); } // Prettier 2.0.4 .class { &:extend( .some-class .some-other-class .some-very-loooooooooooooong-class all ); } // Prettier 2.0.4 (Second format) .class { &: extend( .some-class .some-other-class .some-very-loooooooooooooong-class all ); } // Prettier 2.0.5 .class { &: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`. ### [`v2.0.4`](https://togithub.com/prettier/prettier/blob/master/CHANGELOG.md#204) [Compare Source](https://togithub.com/prettier/prettier/compare/2.0.3...2.0.4) [diff](https://togithub.com/prettier/prettier/compare/2.0.3...2.0.4) ##### Revert [#7869](https://togithub.com/prettier/prettier/pull/7869), "[TypeScript] format TSAsExpression with same logic as BinaryExpression" ([#7958](https://togithub.com/prettier/prettier/pull/7958)) ### [`v2.0.3`](https://togithub.com/prettier/prettier/blob/master/CHANGELOG.md#203) [Compare Source](https://togithub.com/prettier/prettier/compare/2.0.2...2.0.3) [diff](https://togithub.com/prettier/prettier/compare/2.0.2...2.0.3) ##### JavaScript ##### Fix `prettier-ignore` inside JSX ([#7877](https://togithub.com/prettier/prettier/pull/7877) by [@fisker](https://togithub.com/fisker)) ```jsx // Input
