##### Allow custom "else if"-like blocks with block params ([#&#8203;13930](prettier/prettier#13930) by [@&#8203;jamescdavis](https://github.com/jamescdavis))

[#&#8203;13507](prettier/prettier#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.

<!-- prettier-ignore -->

```hbs
{{! Input }}
{{#when isAtWork as |work|}}
  Ship that
  {{work}}!
{{else when isReading as |book|}}

It was a regression in Prettier 2.6.0.

<!-- prettier-ignore -->

```jsx

switch (state) {
  default:
    result = state; // no change
    break;
}

// Prettier 2.8.1

##### Support type annotations on auto accessors via `babel-ts` ([#&#8203;14049](prettier/prettier#14049) by [@&#8203;sosukesuzuki](https://github.com/sosukesuzuki))

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

({}).toString.call(foo.forEach) === "[object Array]"

  : iterateObject(foo);

[diff](prettier/prettier@2.8.6...2.8.7)

##### Allow multiple decorators on same getter/setter ([#14584](prettier/prettier#14584) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```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()
  get foo() {}

  @decorator()
  set foo(value) {}
}
```
##### [\`v2.8.6\`](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#286)

[diff](prettier/prettier@2.8.5...2.8.6)

##### Allow decorators on private members and class expressions ([#14548](prettier/prettier#14548) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```ts
// Input
class A {
  @decorator()
  #privateMethod () {}
}

// Prettier 2.8.5
SyntaxError: Decorators are not valid here. (2:3)
  1 | class A {
> 2 |   @decorator()
    |   ^^^^^^^^^^^^
  3 |   #privateMethod () {}
  4 | }

// Prettier 2.8.6
class A {
  @decorator()
  #privateMethod() {}
}
```
##### [\`v2.8.5\`](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#285)

[diff](prettier/prettier@2.8.4...2.8.5)

##### Support TypeScript 5.0 ([#14391](prettier/prettier#14391) by [@fisker](https://github.com/fisker), [#13819](prettier/prettier#13819) by [@fisker](https://github.com/fisker), [@sosukesuzuki](https://github.com/sosukesuzuki))

TypeScript 5.0 introduces two new syntactic features:

-   `const` modifiers for type parameters
-   `export type *` declarations

##### Add missing parentheses for decorator ([#14393](prettier/prettier#14393) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```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](prettier/prettier#14458) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```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](prettier/prettier#14516) by [@josephfrazier](https://github.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).

<!-- prettier-ignore -->

```html
<!-- Input -->
<div className='HelloWorld' title={`You are visitor number ${ num }`} onMouseOver={onMouseOver}/>

<!-- Prettier 2.8.4 -->
<div
  className="HelloWorld"
  title={`You are visitor number ${num}`}
  onMouseOver={onMouseOver}
/>;

<!-- Prettier 2.8.5 -->
<div className="HelloWorld" title={`You are visitor number ${num}`} onMouseOver={onMouseOver} />;
```
##### [\`v2.8.4\`](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#284)

[diff](prettier/prettier@2.8.3...2.8.4)

##### Fix leading comments in mapped types with `readonly` ([#13427](prettier/prettier#13427) by [@thorn0](https://github.com/thorn0), [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```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](prettier/prettier#14067) by [@jamescdavis](https://github.com/jamescdavis))

This is a follow-up to [#13930](prettier/prettier#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.

<!-- prettier-ignore -->

```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

  Hello

{{! Prettier 2.8.4 }}
{{#block

}}
  Hello
{{else block
  param param param param param param param param param param
  as |blockParam|
}}
  There
{{/block}}
```

##### Ignore files in `.sl/` ([#14206](prettier/prettier#14206) by [@bolinfest](https://github.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](prettier/prettier#14262) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input
const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337});
const b = /** @type {Record<string, string>} */ ({hello: 1337});

// Prettier 2.8.3
const a = /** @Satisfies {Record<string, string>} */ { hello: 1337 };
const b = /** @type {Record<string, string>} */ ({ hello: 1337 });

// Prettier 2.8.4
const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337});
const b = /** @type {Record<string, string>} */ ({hello: 1337});
```

##### Fix parens in inferred function return types with `extends` ([#14279](prettier/prettier#14279) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```ts
// Input
type Foo<T> = T extends ((a) => a is infer R extends string) ? R : never;

// Prettier 2.8.3 (First format)
type Foo<T> = 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> = T extends ((a) => a is infer R extends string) ? R : never;
```
##### [\`v2.8.3\`](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#283)

[diff](prettier/prettier@2.8.2...2.8.3)

##### Allow self-closing tags on custom elements ([#14170](prettier/prettier#14170) by [@fisker](https://github.com/fisker))

See [Angular v15.1.0 release note](https://github.com/angular/angular/releases/tag/15.1.0) for details.

<!-- prettier-ignore -->

```html
// Input
<app-test/>

// Prettier 2.8.2

##### Preserve self-closing tags ([#13691](prettier/prettier#13691) by [@dcyriller](https://github.com/dcyriller))

##### Allow custom "else if"-like blocks with block params ([#13930](prettier/prettier#13930) by [@jamescdavis](https://github.com/jamescdavis))

[#13507](prettier/prettier#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.

<!-- prettier-ignore -->

```hbs
{{! Input }}

##### [\`v2.8.5\`](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#285)

[diff](prettier/prettier@2.8.4...2.8.5)

##### Support TypeScript 5.0 ([#14391](prettier/prettier#14391) by [@fisker](https://github.com/fisker), [#13819](prettier/prettier#13819) by [@fisker](https://github.com/fisker), [@sosukesuzuki](https://github.com/sosukesuzuki))

TypeScript 5.0 introduces two new syntactic features:

-   `const` modifiers for type parameters
-   `export type *` declarations

##### Add missing parentheses for decorator ([#14393](prettier/prettier#14393) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input

```

##### Add parentheses for `TypeofTypeAnnotation` to improve readability ([#14458](prettier/prettier#14458) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```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](prettier/prettier#14516) by [@josephfrazier](https://github.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).

<!-- prettier-ignore -->

```html
<!-- Input -->
<div className='HelloWorld' title={`You are visitor number ${ num }`} onMouseOver={onMouseOver}/>

<!-- Prettier 2.8.4 -->
<div
  className="HelloWorld"
  title={`You are visitor number ${num}`}
  onMouseOver={onMouseOver}
/>;

<!-- Prettier 2.8.5 -->
<div className="HelloWorld" title={`You are visitor number ${num}`} onMouseOver={onMouseOver} />;
```
##### [\`v2.8.4\`](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#284)

[diff](prettier/prettier@2.8.3...2.8.4)

##### Fix leading comments in mapped types with `readonly` ([#13427](prettier/prettier#13427) by [@thorn0](https://github.com/thorn0), [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

  readonly // comment
  [key in Foo];
};

// Prettier 2.8.4
type Type = {
  // comment
  readonly [key in Foo];
};
```

##### Group params in opening block statements ([#14067](prettier/prettier#14067) by [@jamescdavis](https://github.com/jamescdavis))

This is a follow-up to [#13930](prettier/prettier#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.

<!-- prettier-ignore -->

```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|}}

##### Ignore files in `.sl/` ([#14206](prettier/prettier#14206) by [@bolinfest](https://github.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](prettier/prettier#14262) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337});
const b = /** @type {Record<string, string>} */ ({hello: 1337});
```

##### Fix parens in inferred function return types with `extends` ([#14279](prettier/prettier#14279) by [@fisker](https://github.com/fisker))

This version is a republished version of v2.8.7.
A bad version was accidentally published and [it can't be unpublished](npm/cli#1686), apologies for the churn.


## [v2.8.7](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#287)

[diff](prettier/prettier@2.8.6...2.8.7)

##### Allow multiple decorators on same getter/setter ([#14584](prettier/prettier#14584) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```ts
// Input
class A {
  @decorator()

[diff](prettier/prettier@2.8.5...2.8.6)

##### Allow decorators on private members and class expressions ([#14548](prettier/prettier#14548) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```ts
// Input
class A {
  @decorator()
  #privateMethod () {}
}

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

// Prettier 2.8.6
class A {
  @decorator()
  #privateMethod() {}
}
```


## [v2.8.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#285)

[diff](prettier/prettier@2.8.4...2.8.5)

##### Support TypeScript 5.0 ([#14391](prettier/prettier#14391) by [@fisker](https://github.com/fisker), [#13819](prettier/prettier#13819) by [@fisker](https://github.com/fisker), [@sosukesuzuki](https://github.com/sosukesuzuki))

TypeScript 5.0 introduces two new syntactic features:

-   `const` modifiers for type parameters
-   `export type *` declarations

##### Add missing parentheses for decorator ([#14393](prettier/prettier#14393) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```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](prettier/prettier#14458) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```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](prettier/prettier#14516) by [@josephfrazier](https://github.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).

<!-- prettier-ignore -->

```html
<!-- Input -->
<div className='HelloWorld' title={`You are visitor number ${ num }`} onMouseOver={onMouseOver}/>

<!-- Prettier 2.8.4 -->
<div
  className="HelloWorld"
  title={`You are visitor number ${num}`}
  onMouseOver={onMouseOver}
/>;

<!-- Prettier 2.8.5 -->
<div className="HelloWorld" title={`You are visitor number ${num}`} onMouseOver={onMouseOver} />;
```


## [v2.8.4](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#284)

[diff](prettier/prettier@2.8.3...2.8.4)

##### Fix leading comments in mapped types with `readonly` ([#13427](prettier/prettier#13427) by [@thorn0](https://github.com/thorn0), [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```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](prettier/prettier#14067) by [@jamescdavis](https://github.com/jamescdavis))

This is a follow-up to [#13930](prettier/prettier#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.

<!-- prettier-ignore -->

```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

}}
  There
{{/block}}
```

##### Ignore files in `.sl/` ([#14206](prettier/prettier#14206) by [@bolinfest](https://github.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](prettier/prettier#14262) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input
const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337});
const b = /** @type {Record<string, string>} */ ({hello: 1337});

// Prettier 2.8.3
const a = /** @Satisfies {Record<string, string>} */ { hello: 1337 };
const b = /** @type {Record<string, string>} */ ({ hello: 1337 });

// Prettier 2.8.4
const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337});
const b = /** @type {Record<string, string>} */ ({hello: 1337});
```

##### Fix parens in inferred function return types with `extends` ([#14279](prettier/prettier#14279) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```ts
// Input
type Foo<T> = T extends ((a) => a is infer R extends string) ? R : never;

// Prettier 2.8.3 (First format)
type Foo<T> = 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> = T extends ((a) => a is infer R extends string) ? R : never;
```


## [v2.8.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#283)

[diff](prettier/prettier@2.8.2...2.8.3)

##### Allow self-closing tags on custom elements ([#14170](prettier/prettier#14170) by [@fisker](https://github.com/fisker))

See [Angular v15.1.0 release note](https://github.com/angular/angular/releases/tag/15.1.0) for details.

##### Allow custom "else if"-like blocks with block params ([#13930](prettier/prettier#13930) by [@jamescdavis](https://github.com/jamescdavis))

[#13507](prettier/prettier#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.

<!-- prettier-ignore -->

```hbs

##### Support type annotations on auto accessors via `babel-ts` ([#14049](prettier/prettier#14049) by [@sosukesuzuki](https://github.com/sosukesuzuki))

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

[diff](prettier/prettier@2.8.6...2.8.7)

##### Allow multiple decorators on same getter/setter ([#14584](prettier/prettier#14584) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```ts
// Input

  @decorator()
  #privateMethod () {}
}

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

// Prettier 2.8.6
class A {
  @decorator()
  #privateMethod() {}
}
```


## [v2.8.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#285)

[diff](prettier/prettier@2.8.4...2.8.5)

##### Support TypeScript 5.0 ([#14391](prettier/prettier#14391) by [@fisker](https://github.com/fisker), [#13819](prettier/prettier#13819) by [@fisker](https://github.com/fisker), [@sosukesuzuki](https://github.com/sosukesuzuki))

TypeScript 5.0 introduces two new syntactic features:

-   `const` modifiers for type parameters
-   `export type *` declarations

##### Add missing parentheses for decorator ([#14393](prettier/prettier#14393) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```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](prettier/prettier#14458) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```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](prettier/prettier#14516) by [@josephfrazier](https://github.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).

<!-- prettier-ignore -->

```html
<!-- Input -->
<div className='HelloWorld' title={`You are visitor number ${ num }`} onMouseOver={onMouseOver}/>

<!-- Prettier 2.8.4 -->
<div
  className="HelloWorld"
  title={`You are visitor number ${num}`}
  onMouseOver={onMouseOver}
/>;

<!-- Prettier 2.8.5 -->
<div className="HelloWorld" title={`You are visitor number ${num}`} onMouseOver={onMouseOver} />;
```


## [v2.8.4](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#284)

[diff](prettier/prettier@2.8.3...2.8.4)

##### Fix leading comments in mapped types with `readonly` ([#13427](prettier/prettier#13427) by [@thorn0](https://github.com/thorn0), [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```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](prettier/prettier#14067) by [@jamescdavis](https://github.com/jamescdavis))

This is a follow-up to [#13930](prettier/prettier#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.

<!-- prettier-ignore -->

```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

}}
  There
{{/block}}
```

##### Ignore files in `.sl/` ([#14206](prettier/prettier#14206) by [@bolinfest](https://github.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](prettier/prettier#14262) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input
const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337});
const b = /** @type {Record<string, string>} */ ({hello: 1337});

// Prettier 2.8.3
const a = /** @Satisfies {Record<string, string>} */ { hello: 1337 };
const b = /** @type {Record<string, string>} */ ({ hello: 1337 });

// Prettier 2.8.4
const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337});
const b = /** @type {Record<string, string>} */ ({hello: 1337});
```

##### Fix parens in inferred function return types with `extends` ([#14279](prettier/prettier#14279) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```ts
// Input
type Foo<T> = T extends ((a) => a is infer R extends string) ? R : never;

// Prettier 2.8.3 (First format)
type Foo<T> = 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> = T extends ((a) => a is infer R extends string) ? R : never;
```


## [v2.8.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#283)

##### Support type annotations on auto accessors via `babel-ts` ([#14049](prettier/prettier#14049) by [@sosukesuzuki](https://github.com/sosukesuzuki))

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

}
```


## [v2.8.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#285)

[diff](prettier/prettier@2.8.4...2.8.5)

##### Support TypeScript 5.0 ([#14391](prettier/prettier#14391) by [@fisker](https://github.com/fisker), [#13819](prettier/prettier#13819) by [@fisker](https://github.com/fisker), [@sosukesuzuki](https://github.com/sosukesuzuki))

TypeScript 5.0 introduces two new syntactic features:

-   `const` modifiers for type parameters
-   `export type *` declarations

##### Add missing parentheses for decorator ([#14393](prettier/prettier#14393) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```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](prettier/prettier#14458) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```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](prettier/prettier#14516) by [@josephfrazier](https://github.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).

<!-- prettier-ignore -->

```html
<!-- Input -->
<div className='HelloWorld' title={`You are visitor number ${ num }`} onMouseOver={onMouseOver}/>

<!-- Prettier 2.8.4 -->
<div
  className="HelloWorld"
  title={`You are visitor number ${num}`}
  onMouseOver={onMouseOver}
/>;

<!-- Prettier 2.8.5 -->
<div className="HelloWorld" title={`You are visitor number ${num}`} onMouseOver={onMouseOver} />;
```


## [v2.8.4](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#284)

[diff](prettier/prettier@2.8.3...2.8.4)

##### Fix leading comments in mapped types with `readonly` ([#13427](prettier/prettier#13427) by [@thorn0](https://github.com/thorn0), [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```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](prettier/prettier#14067) by [@jamescdavis](https://github.com/jamescdavis))

This is a follow-up to [#13930](prettier/prettier#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.

<!-- prettier-ignore -->

```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

  There

```

##### Ignore files in `.sl/` ([#14206](prettier/prettier#14206) by [@bolinfest](https://github.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](prettier/prettier#14262) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input
const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337});
const b = /** @type {Record<string, string>} */ ({hello: 1337});

// Prettier 2.8.3
const a = /** @Satisfies {Record<string, string>} */ { hello: 1337 };
const b = /** @type {Record<string, string>} */ ({ hello: 1337 });

// Prettier 2.8.4
const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337});
const b = /** @type {Record<string, string>} */ ({hello: 1337});
```

##### Fix parens in inferred function return types with `extends` ([#14279](prettier/prettier#14279) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```ts
// Input

// Prettier 2.8.3 (First format)
type Foo<T> = 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> = T extends ((a) => a is infer R extends string) ? R : never;
```


## [v2.8.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#283)

[diff](prettier/prettier@2.8.2...2.8.3)

##### Allow self-closing tags on custom elements ([#14170](prettier/prettier#14170) by [@fisker](https://github.com/fisker))

##### Allow custom "else if"-like blocks with block params ([#13930](prettier/prettier#13930) by [@jamescdavis](https://github.com/jamescdavis))

[#13507](prettier/prettier#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.

<!-- prettier-ignore -->

```hbs

##### Support type annotations on auto accessors via `babel-ts` ([#14049](prettier/prettier#14049) by [@sosukesuzuki](https://github.com/sosukesuzuki))

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

## [v2.8.8](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#288)

This version is a republished version of v2.8.7.
A bad version was accidentally published and [it can't be unpublished](npm/cli#1686), apologies for the churn.


## [v2.8.7](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#287)

[diff](prettier/prettier@2.8.6...2.8.7)

##### Allow multiple decorators on same getter/setter ([#14584](prettier/prettier#14584) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```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) {}

[diff](prettier/prettier@2.8.5...2.8.6)

##### Allow decorators on private members and class expressions ([#14548](prettier/prettier#14548) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```ts
// Input
class A {
  @decorator()
  #privateMethod () {}
}

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

}
```


## [v2.8.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#285)

[diff](prettier/prettier@2.8.4...2.8.5)

##### Support TypeScript 5.0 ([#14391](prettier/prettier#14391) by [@fisker](https://github.com/fisker), [#13819](prettier/prettier#13819) by [@fisker](https://github.com/fisker), [@sosukesuzuki](https://github.com/sosukesuzuki))

TypeScript 5.0 introduces two new syntactic features:

-   `const` modifiers for type parameters
-   `export type *` declarations

##### Add missing parentheses for decorator ([#14393](prettier/prettier#14393) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```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](prettier/prettier#14458) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```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](prettier/prettier#14516) by [@josephfrazier](https://github.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).

<!-- prettier-ignore -->

```html
<!-- Input -->
<div className='HelloWorld' title={`You are visitor number ${ num }`} onMouseOver={onMouseOver}/>

<!-- Prettier 2.8.4 -->
<div
  className="HelloWorld"
  title={`You are visitor number ${num}`}
  onMouseOver={onMouseOver}
/>;

<!-- Prettier 2.8.5 -->
<div className="HelloWorld" title={`You are visitor number ${num}`} onMouseOver={onMouseOver} />;
```


## [v2.8.4](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#284)

[diff](prettier/prettier@2.8.3...2.8.4)

##### Fix leading comments in mapped types with `readonly` ([#13427](prettier/prettier#13427) by [@thorn0](https://github.com/thorn0), [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```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](prettier/prettier#14067) by [@jamescdavis](https://github.com/jamescdavis))

This is a follow-up to [#13930](prettier/prettier#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.

<!-- prettier-ignore -->

```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

}}
  There
{{/block}}
```

##### Ignore files in `.sl/` ([#14206](prettier/prettier#14206) by [@bolinfest](https://github.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](prettier/prettier#14262) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input
const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337});
const b = /** @type {Record<string, string>} */ ({hello: 1337});

// Prettier 2.8.3
const a = /** @Satisfies {Record<string, string>} */ { hello: 1337 };
const b = /** @type {Record<string, string>} */ ({ hello: 1337 });

// Prettier 2.8.4
const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337});
const b = /** @type {Record<string, string>} */ ({hello: 1337});
```

##### Fix parens in inferred function return types with `extends` ([#14279](prettier/prettier#14279) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```ts
// Input
type Foo<T> = T extends ((a) => a is infer R extends string) ? R : never;

// Prettier 2.8.3 (First format)
type Foo<T> = 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> = T extends ((a) => a is infer R extends string) ? R : never;
```


## [v2.8.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#283)

[diff](prettier/prettier@2.8.2...2.8.3)

##### Allow self-closing tags on custom elements ([#14170](prettier/prettier#14170) by [@fisker](https://github.com/fisker))

See [Angular v15.1.0 release note](https://github.com/angular/angular/releases/tag/15.1.0) for details.

<!-- prettier-ignore -->

##### Allow custom "else if"-like blocks with block params ([#13930](prettier/prettier#13930) by [@jamescdavis](https://github.com/jamescdavis))

[#13507](prettier/prettier#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.

<!-- prettier-ignore -->

```hbs
{{! Input }}
{{#when isAtWork as |work|}}
  Ship that
  {{work}}!
{{else when isReading as |book|}}

<!-- prettier-ignore -->

```scss

  'one': (
     'key': 'value',
  ),

  'two': (
     'key': 'value',
  ),

##### Fix missing parentheses when an expression statement starts with `let[` ([#14000](prettier/prettier#14000), [#14044](prettier/prettier#14044) by [@fisker](https://github.com/fisker), [@thorn0](https://github.com/thorn0))

<!-- prettier-ignore -->

```jsx

// Prettier 2.8.1 (second format)
SyntaxError: Unexpected token (1:5)

##### Support type annotations on auto accessors via `babel-ts` ([#14049](prettier/prettier#14049) by [@sosukesuzuki](https://github.com/sosukesuzuki))

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

##### Support TypeScript 5.0 ([#14391](prettier/prettier#14391) by [@fisker](https://github.com/fisker), [#13819](prettier/prettier#13819) by [@fisker](https://github.com/fisker), [@sosukesuzuki](https://github.com/sosukesuzuki))

TypeScript 5.0 introduces two new syntactic features:

-   `const` modifiers for type parameters
-   `export type *` declarations

##### Add missing parentheses for decorator ([#14393](prettier/prettier#14393) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```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](prettier/prettier#14458) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```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](prettier/prettier#14516) by [@josephfrazier](https://github.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).

<!-- prettier-ignore -->

```html
<!-- Input -->
<div className='HelloWorld' title={`You are visitor number ${ num }`} onMouseOver={onMouseOver}/>

<!-- Prettier 2.8.4 -->
<div
  className="HelloWorld"
  title={`You are visitor number ${num}`}
  onMouseOver={onMouseOver}
/>;

<!-- Prettier 2.8.5 -->
<div className="HelloWorld" title={`You are visitor number ${num}`} onMouseOver={onMouseOver} />;
```


## [v2.8.4](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#284)

[diff](prettier/prettier@2.8.3...2.8.4)

##### Fix leading comments in mapped types with `readonly` ([#13427](prettier/prettier#13427) by [@thorn0](https://github.com/thorn0), [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```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](prettier/prettier#14067) by [@jamescdavis](https://github.com/jamescdavis))

This is a follow-up to [#13930](prettier/prettier#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.

<!-- prettier-ignore -->

```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|}}

```

##### Ignore files in `.sl/` ([#14206](prettier/prettier#14206) by [@bolinfest](https://github.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](prettier/prettier#14262) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input
const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337});
const b = /** @type {Record<string, string>} */ ({hello: 1337});

// Prettier 2.8.3
const a = /** @Satisfies {Record<string, string>} */ { hello: 1337 };
const b = /** @type {Record<string, string>} */ ({ hello: 1337 });

// Prettier 2.8.4
const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337});
const b = /** @type {Record<string, string>} */ ({hello: 1337});
```

##### Fix parens in inferred function return types with `extends` ([#14279](prettier/prettier#14279) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```ts
// Input
type Foo<T> = T extends ((a) => a is infer R extends string) ? R : never;

// Prettier 2.8.3 (First format)
type Foo<T> = 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> = T extends ((a) => a is infer R extends string) ? R : never;
```


## [v2.8.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#283)

##### Allow custom "else if"-like blocks with block params ([#13930](prettier/prettier#13930) by [@jamescdavis](https://github.com/jamescdavis))

[#13507](prettier/prettier#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.

<!-- prettier-ignore -->

```hbs
{{! Input }}
{{#when isAtWork as |work|}}

##### Fix missing parentheses when an expression statement starts with `let[` ([#14000](prettier/prettier#14000), [#14044](prettier/prettier#14044) by [@fisker](https://github.com/fisker), [@thorn0](https://github.com/thorn0))

<!-- prettier-ignore -->

```jsx

```

##### Support type annotations on auto accessors via `babel-ts` ([#14049](prettier/prettier#14049) by [@sosukesuzuki](https://github.com/sosukesuzuki))

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

<!-- prettier-ignore -->

```tsx

[diff](prettier/prettier@2.8.6...2.8.7)

##### Allow multiple decorators on same getter/setter ([#14584](prettier/prettier#14584) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```ts
// Input

##### Allow decorators on private members and class expressions ([#14548](prettier/prettier#14548) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```ts

```


## [v2.8.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#285)

[diff](prettier/prettier@2.8.4...2.8.5)

##### Support TypeScript 5.0 ([#14391](prettier/prettier#14391) by [@fisker](https://github.com/fisker), [#13819](prettier/prettier#13819) by [@fisker](https://github.com/fisker), [@sosukesuzuki](https://github.com/sosukesuzuki))

TypeScript 5.0 introduces two new syntactic features:

-   `const` modifiers for type parameters
-   `export type *` declarations

##### Add missing parentheses for decorator ([#14393](prettier/prettier#14393) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input
class Person {
  @(myDecoratorArray[0])
  greet() {}
}

// Prettier 2.8.4
class Person {
  @myDecoratorArray[0]
  greet() {}
}

// Prettier 2.8.5
class Person {

##### Add parentheses for `TypeofTypeAnnotation` to improve readability ([#14458](prettier/prettier#14458) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```tsx
// Input
type A = (typeof node.children)[];

// Prettier 2.8.4

```

##### Support `max_line_length=off` when parsing `.editorconfig` ([#14516](prettier/prettier#14516) by [@josephfrazier](https://github.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).

<!-- prettier-ignore -->

```html
<!-- Input -->
<div className='HelloWorld' title={`You are visitor number ${ num }`} onMouseOver={onMouseOver}/>

<!-- Prettier 2.8.4 -->
<div
  className="HelloWorld"
  title={`You are visitor number ${num}`}
  onMouseOver={onMouseOver}
/>;

<!-- Prettier 2.8.5 -->
<div className="HelloWorld" title={`You are visitor number ${num}`} onMouseOver={onMouseOver} />;

##### Group params in opening block statements ([#14067](prettier/prettier#14067) by [@jamescdavis](https://github.com/jamescdavis))

This is a follow-up to [#13930](prettier/prettier#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|}}
