+#### JavaScript: Fix breaks indentation and idempotency when an arrow function that args include object pattern is passed to a function as parameter. ([#6301] by [@sosukesuzuki])
+
+Previously, Prettier collapses strangely, when an arrow function that args include object pattern is passed to a function as parameter. Also, it breaks idempotency. Please see [#6294](https://github.com/prettier/prettier/issues/6294) for detail.
