 ## Unreleased
 
   - Rename `Task#stop` to `Task#cancel` for better clarity and consistency with common concurrency terminology. The old `stop` method is still available as an alias for backward compatibility, but it is recommended to use `cancel` going forward.
+  - Forward arguments from `Task#wait` -> `Promise#wait`, so `task.wait(timeout: N)` is supported.
 
 ## v2.37.0
 
   - Introduce `Async::Loop` for robust, time-aligned loops.
+  - Add support for `Async::Promise#wait(timeout: N)`.
 
 ## v2.36.0
