+## [5.0.0] - 2026-02-20
+
+### Changed
+
+- **Breaking change:** All model types have been changed from `class`es to `record`s.
+- **Breaking change:** All property accessors on model types have changed from `{ get; set; }` to `{ get; init; }`.
+
+### Removed
+
+- **Breaking change:** `JsonApiLinksObject` has been removed.
+
+### Remarks
+
+This version refactors the entire model into immutable `record` types. While opinionated, I'm convinced this change is in the best interest of creating robust and resilient code.
+
+If you're not willing to part with mutable `class`es, this version is otherwise identical to version 4.0.0.
