-- Remove `bench` Cargo feature (by shifting benchmarks out of `src/lib.rs` into
- `benches/bench.rs`; it still won’t run on anything but nightly, but that
- don’t signify). Technically a [breaking-change], but it was something for
- development only, so I’m not in the slightest bit concerned by it.
+- Removed the `bench` Cargo feature which was mostly to work around historical
+ Cargo limitations, but was solved by moving benchmarks from `src/lib.rs` to
+ `benches/bench.rs` even before those limitations were lifted. The benchmarks
+ still won’t run on anything but nightly, but that don’t signify.
