+# [v0.51.0](https://github.com/rust-lang/rustdoc-types/releases/tag/v0.51.0) - 2025-06-23
+
+**Breaking Change**: Change `AssocItemConstraint::args` and `Type::QualifiedPath::args` from `GenericArgs` to `Option<Box<GenericArgs>>`.
+This is consistent with `Path::args`, and smaller on disk ([rust#142502](https://github.com/rust-lang/rust/pull/142502)).
