### [`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 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 as |blockParam| }} 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; ```
