[#​6199]: [#​6199](https://togithub.com/prettier/prettier/pull/6199) [@​duailibe]: ### [`v1.18.1`](https://togithub.com/prettier/prettier/blob/master/CHANGELOG.md#​1181) [Compare Source](https://togithub.com/prettier/prettier/compare/1.18.0...1.18.1) [diff](https://togithub.com/prettier/prettier/compare/1.18.0...1.18.1) - 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"; } function function1() { return "one"; } // Output (Prettier 1.18.1) interface Interface1 { one: "one"; } function function1() { return "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 [#​6190]: https://togithub.com/prettier/prettier/pull/6190 [#​6194]: https://togithub.com/prettier/prettier/pull/6194 [@​duailibe]: https://togithub.com/duailibe [@​sosukesuzuki]: https://togithub.com/sosukesuzuki ### [`v1.18.0`](https://togithub.com/prettier/prettier/blob/master/CHANGELOG.md#​1180) [Compare Source](https://togithub.com/prettier/prettier/compare/1.17.1...1.18.0) [diff](https://togithub.com/prettier/prettier/compare/1.17.1...1.18.0) 🔗 [Release Notes](https://prettier.io/blog/2019/06/06/1.18.0.html)
