##### Support TypeScript 4.3 ([#10945](https://togithub.com/prettier/prettier/pull/10945) by [@sosukesuzuki](https://togithub.com/sosukesuzuki))
##### [`override` modifiers in class elements](https://devblogs.microsoft.com/typescript/announcing-typescript-4-3/#override)
```ts
class Foo extends {
override method() {}
}
```
##### [static index signatures (`[key: KeyType]: ValueType`) in classes](https://devblogs.microsoft.com/typescript/announcing-typescript-4-3/#static-index-signatures)
```ts
class Foo {
static [key: string]: Bar;
}
```
##### [`get` / `set` in type declarations](https://devblogs.microsoft.com/typescript/announcing-typescript-4-3/#separate-write-types)
```ts
interface Foo {
set foo(value);
get foo(): string;
}
```
##### Preserve attributes order for element node ([#10958](https://togithub.com/prettier/prettier/pull/10958) by [@dcyriller](https://github.comdcyriller))
```handlebars
{{!-- Input --}}
{{!-- Prettier stable --}}
{{!-- Prettier main --}}
```
##### Track cursor position properly when it’s at the end of the range to format ([#10938](https://togithub.com/prettier/prettier/pull/10938) by [@j-f1](https://togithub.com/j-f1))
Previously, if the cursor was at the end of the range to format, it would simply be placed back at the end of the updated range.
Now, it will be repositioned if Prettier decides to add additional code to the end of the range (such as a semicolon).
```jsx
// Input (<|> represents the cursor)
const someVariable = myOtherVariable<|>
// range to format: ^^^^^^^^^^^^^^^
// Prettier stable
const someVariable = myOtherVariable;<|>
// range to format: ^^^^^^^^^^^^^^^
// Prettier main
const someVariable = myOtherVariable<|>;
// range to format: ^^^^^^^^^^^^^^^
```
##### Break the LHS of type alias that has complex type parameters ([#10901](https://togithub.com/prettier/prettier/pull/10901) by [@sosukesuzuki](https://togithub.com/sosukesuzuki))
```ts
// Input
type FieldLayoutWith<
T extends string,
S extends unknown = { width: string }
> = {
type: T;
code: string;
size: S;
};
// Prettier stable
type FieldLayoutWith =
{
type: T;
code: string;
size: S;
};
// Prettier main
type FieldLayoutWith<
T extends string,
S extends unknown = { width: string }
> = {
type: T;
code: string;
size: S;
};
```
##### Break the LHS of assignments that has complex type parameters ([#10916](https://togithub.com/prettier/prettier/pull/10916) by [@sosukesuzuki](https://togithub.com/sosukesuzuki))
```ts
// Input
const map: Map<
Function,
Map
> = new Map();
// Prettier stable
const map: Map> =
new Map();
// Prettier main
const map: Map<
Function,
Map
> = new Map();
```
##### Fix incorrectly wrapped arrow functions with return types ([#10940](https://togithub.com/prettier/prettier/pull/10940) by [@thorn0](https://togithub.com/thorn0))
```ts
// Input
longfunctionWithCall12("bla", foo, (thing: string): complex> => {
code();
});
// Prettier stable
longfunctionWithCall12("bla", foo, (thing: string): complex<
type
> => {
code();
});
// Prettier main
longfunctionWithCall12(
"bla",
foo,
(thing: string): complex> => {
code();
}
);
```
##### Avoid breaking call expressions after assignments with complex type arguments ([#10949](https://togithub.com/prettier/prettier/pull/10949) by [@sosukesuzuki](https://togithub.com/sosukesuzuki))
```ts
// Input
const foo = call<{
prop1: string;
prop2: string;
prop3: string;
}>();
// Prettier stable
const foo =
call<{
prop1: string;
prop2: string;
prop3: string;
}>();
// Prettier main
const foo = call<{
prop1: string;
prop2: string;
prop3: string;
}>();
```
##### Fix order of `override` modifiers ([#10961](https://togithub.com/prettier/prettier/pull/10961) by [@sosukesuzuki](https://togithub.com/sosukesuzuki))
```ts
// Input
class Foo extends Bar {
abstract override foo: string;
}
// Prettier stable
class Foo extends Bar {
abstract override foo: string;
}
// Prettier main
class Foo extends Bar {
abstract override foo: string;
}
```

##### Less: Fix formatting of `:extend` ([#7984](https://togithub.com/prettier/prettier/pull/7984) by [@fisker](https://togithub.com/fisker))
```less
// Input

&: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`.

##### Do not add comma for explicit inexact object with indexer property or no properties ([#7923](https://togithub.com/prettier/prettier/pull/7923) by [@DmitryGonchar](https://togithub.com/DmitryGonchar))

##### 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

// Prettier 2.0.0
