 - Correct version chunk splitting in the internal version sort algorithm [#6407](https://github.com/rust-lang/rustfmt/pull/6407)
 - Extend support for single line let-chain formatting to include cases where the left hand side operand is a literal, in alignment with finalized style rules as part of let-chain stabilization [#6492](https://github.com/rust-lang/rustfmt/pull/6492)
 - Begin initial formatting for `use closures` and `use chains` (`#![feature(ergonomic_clones)]`). Previously, the closure and chain was left as the developer wrote it [#6532](https://github.com/rust-lang/rustfmt/pull/6532)

+- Disable the `bytecount/generic-simd` optional dependency when using the `generic-simd` feature. The dependency was preventing rustfmt from building on nightly. simd support will be re-enabled once the issue has been fixed [#6807](https://github.com/rust-lang/rustfmt/pull/6807) [llogiq/bytecount#100](https://github.com/llogiq/bytecount/pull/100)
