+## 2.1.0 - 2025-03-02
+
+### Added
+
+* Add support for retrieving properties on collection items that are accessible via
+  magic methods `__get` and `__isset` ([#126](https://github.com/ramsey/collection/pull/126))
+* Certify support for PHP 8.3 and 8.4 ([#127](https://github.com/ramsey/collection/pull/127))
+
+### Fixed
+
+* Use the correct return type annotation of `list<T>` instead of `array<int, mixed>`
+  for `CollectionInterface::column()` ([#124](https://github.com/ramsey/collection/issues/124))
+* If an element has a property and method of the same name, check the property visibility
+  on the element before attempting to access it; if it is private, attempt to call the
+  method instead ([#123](https://github.com/ramsey/collection/pull/123))
+* `ValueExtractorTrait` expects `getType(): string` to exist on the using class, but it did
+  not declare an abstract to force this requirement; now it does, and any classes using this
+  trait must implement `getType(): string`
+* Avoid calling `contains()` twice when using `AbstractSet::add()`, significantly improving
+  performance for very large collections ([#68](https://github.com/ramsey/collection/issues/68))
