+# [v0.32.2](https://github.com/aDotInTheVoid/rustdoc-types/releases/tag/v0.32.2) - 2024-10-23
+
+**Library Improvement**: `ItemKind`, `TraitBoundModifier`, and `MacroKind` all now implement `Copy` ([rust#131976](https://github.com/rust-lang/rust/pull/131976)).

 # [v0.32.1](https://github.com/aDotInTheVoid/rustdoc-types/releases/tag/v0.32.1) - 2024-10-20
 
 **New Feature**: The optional `rustc-hash` cargo feature has been added.
 This changes the hashing algorithm used to [a speedy non-cryptographic hashing algorith](https://github.com/rust-lang/rustc-hash) also used in rustc. 
-This has lead to [modest but appreciable](https://rust-lang.zulipchat.com/#narrow/channel/266220-t-rustdoc/topic/rustc-hash.20and.20performance.20of.20rustdoc-types/near/474855731) performace gains for some consumers.

+//! We expose a `rustc-hash` feature that is disabled by default. This feature switches the
+//! [`std::collections::HashMap`] for [`rustc_hash::FxHashMap`] to improve the performance of said
+//! `HashMap` in specific situations.
+//!
+//! `cargo-semver-checks` for example, saw a [-3% improvement][1] when benchmarking using the
+//! `aws_sdk_ec2` JSON output (~500MB of JSON). As always, we recommend measuring the impact before
+//! turning this feature on, as [`FxHashMap`][2] only concerns itself with hash speed, and may
+//! increase the number of collisions.
