+## [Unreleased]
+
+-   **New class-based API.** More ergonomic for managing large resource definitions and
+    inheriting/overriding behavior. Complex fields can be extracted into their own classes and
+    reused across resources.
+
+-   **Typed attributes.** Implementations of typed attributes are provided to match the data types
+    in the OpenAPI specification. Attributes can be marked as required and nullable.
+
+-   **Customizable endpoints.** Each endpoint is now opt-in for each resource and can be configured
+    and implemented separately. Also adds the ability for custom endpoints to be added.
+
+-   **Restructured internals.** The codebase is cleaner and easier to reason about, especially the
+    serialization process.
+
+Still to come:
+
+-   Implementation of Laravel stuff (currently it is documented but not implemented)
+-   Ability to generate OpenAPI definitions
+-   Additional attribute types (array, object)
+-   Benchmarks
