```ts
// Input
class A {
@decorator()
get foo () {}
@decorator()
set foo (value) {}
}
// Prettier 2.8.6
SyntaxError: Decorators cannot be applied to multiple get/set accessors of the same name. (5:3)
3 | get foo () {}
4 |
> 5 | @decorator()
| ^^^^^^^^^^^^
6 | set foo (value) {}
7 | }
// Prettier 2.8.7
class A {
@decorator()

@decorator()

}
```

@decorator()
#privateMethod () {}

// Prettier 2.8.5
SyntaxError: Decorators are not valid here. (2:3)
1 | class A {

| ^^^^^^^^^^^^
3 | #privateMethod () {}
4 | }
// Prettier 2.8.6
class A {
@decorator()
#privateMethod() {}
}
```
### [`v2.8.5`](https://togithub.com/prettier/prettier/blob/HEAD/CHANGELOG.md#285)
[Compare Source](https://togithub.com/prettier/prettier/compare/2.8.4...2.8.5)
[diff](https://togithub.com/prettier/prettier/compare/2.8.4...2.8.5)
##### Support TypeScript 5.0 ([#14391](https://togithub.com/prettier/prettier/pull/14391) by [@fisker](https://togithub.com/fisker), [#13819](https://togithub.com/prettier/prettier/pull/13819) by [@fisker](https://togithub.com/fisker), [@sosukesuzuki](https://togithub.com/sosukesuzuki))
TypeScript 5.0 introduces two new syntactic features:
- `const` modifiers for type parameters
- `export type *` declarations
##### Add missing parentheses for decorator ([#14393](https://togithub.com/prettier/prettier/pull/14393) by [@fisker](https://togithub.com/fisker))
```jsx
// Input
class Person {
@(myDecoratorArray[0])
greet() {}
}
// Prettier 2.8.4
class Person {
@myDecoratorArray[0]
greet() {}
}
// Prettier 2.8.5
class Person {
@(myDecoratorArray[0])
greet() {}
}
```
##### Add parentheses for `TypeofTypeAnnotation` to improve readability ([#14458](https://togithub.com/prettier/prettier/pull/14458) by [@fisker](https://togithub.com/fisker))
```tsx
// Input
type A = (typeof node.children)[];
// Prettier 2.8.4
type A = typeof node.children[];
// Prettier 2.8.5
type A = (typeof node.children)[];
```
##### Support `max_line_length=off` when parsing `.editorconfig` ([#14516](https://togithub.com/prettier/prettier/pull/14516) by [@josephfrazier](https://togithub.com/josephfrazier))
If an .editorconfig file is in your project and it sets `max_line_length=off` for the file you're formatting,
it will be interpreted as a `printWidth` of `Infinity` rather than being ignored
(which previously resulted in the default `printWidth` of 80 being applied, if not overridden by Prettier-specific configuration).
```html
;
;
```
### [`v2.8.4`](https://togithub.com/prettier/prettier/blob/HEAD/CHANGELOG.md#284)
[Compare Source](https://togithub.com/prettier/prettier/compare/2.8.3...2.8.4)
[diff](https://togithub.com/prettier/prettier/compare/2.8.3...2.8.4)
##### Fix leading comments in mapped types with `readonly` ([#13427](https://togithub.com/prettier/prettier/pull/13427) by [@thorn0](https://togithub.com/thorn0), [@sosukesuzuki](https://togithub.com/sosukesuzuki))
```tsx
// Input
type Type = {
// comment
readonly [key in Foo];
};
// Prettier 2.8.3
type Type = {
readonly // comment
[key in Foo];
};
// Prettier 2.8.4
type Type = {
// comment
readonly [key in Foo];
};
```
##### Group params in opening block statements ([#14067](https://togithub.com/prettier/prettier/pull/14067) by [@jamescdavis](https://togithub.com/jamescdavis))
This is a follow-up to [#13930](https://togithub.com/prettier/prettier/issues/13930) to establish wrapping consistency between opening block statements and else blocks by
grouping params in opening blocks. This causes params to break to a new line together and not be split across lines
unless the length of params exceeds the print width. This also updates the else block wrapping to behave exactly the
same as opening blocks.
```hbs
{{! Input }}
{{#block param param param param param param param param param param as |blockParam|}}
Hello
{{else block param param param param param param param param param param as |blockParam|}}
There
{{/block}}
{{! Prettier 2.8.3 }}
{{#block
param
param
param
param
param
param
param
param
param
param
as |blockParam|
}}
Hello
{{else block param
param
param
param
param

There
{{/block}}
{{! Prettier 2.8.4 }}
{{#block
param param param param param param param param param param
as |blockParam|
}}
Hello
{{else block
param param param param param param param param param param

}}
There
{{/block}}
```
##### Ignore files in `.sl/` ([#14206](https://togithub.com/prettier/prettier/pull/14206) by [@bolinfest](https://togithub.com/bolinfest))
In [Sapling SCM](https://sapling-scm.com/), `.sl/` is the folder where it stores its state, analogous to `.git/` in Git. It should be ignored in Prettier like the other SCM folders.
##### Recognize `@satisfies` in Closure-style type casts ([#14262](https://togithub.com/prettier/prettier/pull/14262) by [@fisker](https://togithub.com/fisker))
```jsx
// Input
const a = /** @satisfies {Record} */ ({hello: 1337});
const b = /** @type {Record} */ ({hello: 1337});
// Prettier 2.8.3
const a = /** @satisfies {Record} */ { hello: 1337 };
const b = /** @type {Record} */ ({ hello: 1337 });
// Prettier 2.8.4
const a = /** @satisfies {Record} */ ({hello: 1337});
const b = /** @type {Record} */ ({hello: 1337});
```
##### Fix parens in inferred function return types with `extends` ([#14279](https://togithub.com/prettier/prettier/pull/14279) by [@fisker](https://togithub.com/fisker))
```ts
// Input
type Foo = T extends ((a) => a is infer R extends string) ? R : never;
// Prettier 2.8.3 (First format)
type Foo = T extends (a) => a is infer R extends string ? R : never;
// Prettier 2.8.3 (Second format)
SyntaxError: '?' expected.
// Prettier 2.8.4
type Foo = T extends ((a) => a is infer R extends string) ? R : never;
```

[Compare Source](https://togithub.com/prettier/prettier/compare/2.8.2...2.8.3)
[diff](https://togithub.com/prettier/prettier/compare/2.8.2...2.8.3)
##### Allow self-closing tags on custom elements ([#14170](https://togithub.com/prettier/prettier/pull/14170) by [@fisker](https://togithub.com/fisker))
See [Angular v15.1.0 release note](https://togithub.com/angular/angular/releases/tag/15.1.0) for details.
```html
// Input

##### Preserve self-closing tags ([#13691](https://togithub.com/prettier/prettier/pull/13691) by [@dcyriller](https://togithub.com/dcyriller))
```hbs
{{! Input }}

{{! Prettier 2.8.2 }}
```
##### Allow custom "else if"-like blocks with block params ([#13930](https://togithub.com/prettier/prettier/pull/13930) by [@jamescdavis](https://togithub.com/jamescdavis))
[#13507](https://togithub.com/prettier/prettier/issues/13507) added support for custom block keywords used with `else`, but failed to allow block params. This updates printer-glimmer to allow block params with custom "else if"-like blocks.
```hbs
{{! Input }}
{{#when isAtWork as |work|}}
Ship that
{{work}}!
{{else when isReading as |book|}}
You can finish
{{book}}
eventually...
{{else}}

/* Prettier 2.8.2 */
$map: (
'one': (
'key': 'value',
),
'two': (
'key': 'value',
),
)
```
##### Fix missing parentheses when an expression statement starts with `let[` ([#14000](https://togithub.com/prettier/prettier/pull/14000), [#14044](https://togithub.com/prettier/prettier/pull/14044) by [@fisker](https://togithub.com/fisker), [@thorn0](https://togithub.com/thorn0))
```jsx
// Input

(let)[0] = 2;
```

}
.unary_minus_multi {

}
```
##### Add parentheses for TSTypeQuery to improve readability ([#14042](https://togithub.com/prettier/prettier/pull/14042) by [@onishi-kohei](https://togithub.com/onishi-kohei))

It was a regression in Prettier 2.6.0.

[The bug that `@babel/parser` cannot parse auto accessors with type annotations](https://togithub.com/babel/babel/issues/15205) has been fixed. So we now support it via `babel-ts` parser.
