 [v0.4.0 milestone]: https://github.com/rust-marker/marker/milestone/4
 [#278]: https://github.com/rust-marker/marker/pull/278
+[#288]: https://github.com/rust-marker/marker/pull/288
 
 ### Breaking Changes
 - [#278]: Moved the `span()` method from the inherent impl to `HasSpan` trait for `ClosureParam`, `FnParam`, `StructFieldPat`.
 - [#278]: The trait `TyData` no longer has own `span()` method, but instead requires `HasSpan` as a supertrait.
 - [#278]: All public methods that took `&Span` as a parameter now take `impl HasSpan`. This is a minor breaking change, as `&Span` implements `HasSpan`, but if you relied on type inference based on the function parameter type, then making a method generic may break your code.
+- [#288]: Lint identifiers use the lint crate name as a new infix, to prevent name collisions across lint crates.
