@@ -50,6 +50,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - **Go-to-definition, rename, and highlight accuracy.** References in `@see` tags to qualified names like `App\Foo::bar()` now land on the correct location, and renaming a property selects the whole `$name` instead of `$nam`.
 - **`@phpstan-require-extends` and `@phpstan-require-implements` navigation.** Class and interface names in these trait constraint tags now support go-to-definition and hover, and an import used only by such a tag is no longer flagged as unused. Contributed by @calebdw in https://github.com/PHPantom-dev/phpantom_lsp/pull/172.
 - **Renaming variables captured by nested closures and arrow functions.** Renaming or finding references to a variable used inside deeply nested arrow functions (`fn () => fn () => $var`) or closures with `use ($var)` now updates every occurrence, whether the rename is triggered on the declaration or from deep inside the nesting. Contributed by @calebdw in https://github.com/AJenbo/phpantom_lsp/pull/145.
+- **Member rename stays scoped to the declaration it targets.** Renaming a method or property no longer touches same-named members on unrelated classes. A private method rename updates only that method and its real usages, calls on a receiver whose type cannot be resolved are left alone, renaming one implementation of an interface no longer renames sibling implementations, and renaming a child override stays on the child branch. Renaming a parent or interface declaration still updates the inherited overrides and implemented usages. Contributed by @calebdw in https://github.com/PHPantom-dev/phpantom_lsp/pull/160.
 - **Find references on a constructor lists every call site.** Finding references to a `__construct` declaration now reports the `new ClassName(...)` instantiations, `#[ClassName(...)]` attribute usages, and explicit delegation calls written as `parent::__construct()`, `self::__construct()`, or `Class::__construct()`, including for subclasses that inherit the constructor (and excluding subclasses that override it). Attribute classes that are never written as `new` are now found. Contributed by @RemcoSmitsDev in https://github.com/AJenbo/phpantom_lsp/pull/155.
 - **Positions on lines with multibyte characters.** Signature help, go-to-definition on virtual properties, named-argument completion, unused-import removal, and the `@phpstan-ignore` quickfix placed cursors and edits at the wrong column on lines containing multibyte characters; they now use the correct UTF-16 columns. Type strings containing `*` wildcards or variance annotations are also no longer mangled.
 - **Unused-import hint location.** When two imports share a name prefix (`use App\Foo;` and `use App\FooBar;`), the "unused import" dimming now lands on the correct statement.
